EMCrit 393 – CV-EMCrit – Inotrope Basics Part 1 and 2

What Heart Rate to Shoot For?

90-110 in most patients (may go higher if compensating for RHF or extremely low EF)

The Inotropes
Dobutamine, the ChronoInotrope

Hits B1, B2 and at higher doses, alpha

Not as much vasodilation as milrinone, but a lot of chronotropy and the possibility of arrhythmia induction

Dose: 1-5 mcg/kg/min (can go up to 10, but you start risking excessive chronotropy)

Milrinone, the InoDilator

Phosphodiesterase-3 (PDE-3) inhibitor that increases cAMP levels in cardiac myocytes by inhibiting cAMP breakdown by the PDE-3 enzyme leading to increased availability of Ca

Inotropy, lusitropy, but not as much chronotropy. Also comes with vasodilation (arterial, venous, and pulmonary arterial)

Our Dose Recs: 0.125 – 0.25 mcg/kg/min (max out at 0.37 mcg/kg/min)

45 minutes to see effect, avoid in ED because of long half life and Epi can do most of what Milrinone does.

Inotropic Epinephrine, Dual-faced: the pure Inotrope/Inopressor

0.01-0.08 mcg/kg/min (for a 70 kg pt, this is 1-5 mcg/min)

Hits B1, B2, and at higher doses, Alpha

Digoxin, Original-G

Trina uses this in AF with RVR in patients with reduced EF

30-45 min before you see clinical effects after a bolus

Delayed clearance with renal dysfunction

125-250 mcg bolus, may repeat x 1, two hours after 1st dose

after those 2 boluses, you really need levels

Calcium, “God’s” Inotrope

Correct low ionized calcium, will improve inotropy and hypotension if ionized calcium is low.

Dopamine, Fool’s Inotrope

Just don’t do it, just don’t…

  4. Atropine 1mg
  5. Epinephrine drip or push dose
  6. Calcium 3g IV over 5-10min
  7. Isoproterenol great for bradycardia but very expensive so pharmacy may not carry it

Urology Suite: Stone Cold Facts

Chris Reilly, MD, and Meghan Cooper, DO

Dr. Reilly and Dr. Cooper discuss the diagnosis and ED management of kidney stones.

Kidney Stones: 

  • Does size matter?
    • Stones <5 mm have >90% chance of passing in 2-4 weeks.
    • Stones 5-7mm have a 50%-60% chance of passing.
    • Stones >7mm have a <30% chance of passing. 
    • Prior stone formers may be able to pass larger stones and have lesser symptoms. 
  • Hydronephrosis and obstruction may lead to pyelovenous backflow, increasing the chance of infection. 
  • Staghorn canaliculi act as a nidus for recurrent infections but do not necessarily increase the risk for sepsis. 
  • Nonsteroidal anti-inflammatory drugs (NSAIDs) are the preferred pain regimen and more effective than opiates. 
  • Imaging:
    • In undifferentiated or sicker patients, computed tomography (CT) may be indicated.
    • For well-appearing patients who appear to have uncomplicated kidney stones, it is reasonable to try expectant management for 2-3 weeks with strict return precautions. 
    • Renal ultrasound may rule out other pathology or show some features of kidney stones (eg, hydronephrosis, absence of ureteral jets) 
  • Lab testing has a limited role in diagnosis of kidney stones but may be helpful preoperatively or to assess underlying kidney function. Impaired kidney function is not an absolute indication for surgery unless there is a solitary kidney or bilateral obstruction. 
  • It is reasonable to consider outpatient management with antibiotics and strict return precautions for patients with a positive urinalysis and kidney stones if they are well-appearing and non-septic.
  • Risky features for kidney stones that may warrant admission include pregnancy, immunosuppression, solitary kidney, renal dysfunction, or uncontrolled pain/nausea. 

PEARL: Many patients with kidney stones can be managed as outpatients; the most important feature is clinical appearance as these patients can become quite septic.

Spinal Epidural Abscess

David Talan, MD

Dr. Dave Talan discusses the difficult and often missed diagnosis of spinal epidural abscess. This segment reviews the most common risk factors, imaging of choice, and antibiotic coverage for this elusive cause of back pain. 

  • Diagnosing spinal epidural abscess
    • On average, it is diagnosed on the third ED visit.
      • Only 10% of patients present with the classic triad of fever, back pain, and neurological deficits.
    • Risk factors:
      • Intravenous drug use
      • Diabetes
      • Transplant history
      • Bacteremia
      • Recent spinal procedure
    • Spinal epidural abscesses affect the thoracic back more commonly than other causes of back pain; therefore, thoracic pain should raise your level of concern
    • Erythrocyte sedimentation rate (ESR) is not specific and may not be sensitive in early infection.
    • Order magnetic resonance imaging (MRI) with contrast of the whole spine given the frequency of skip lesions
      • Prioritize transfer if MRI is unavailable at your institution.
    • A CT myelogram relies on accuracy of locating the epidural abscess by history and exam.
  • Treatment
    • Draw blood cultures.
    • Antibiotics:
      • If septic, start empiric antibiotics that cover Staphylococcus and gram-negative bacteria, including Pseudomonas, with vancomycin and a broad-spectrum cephalosporin
      • If the patient is being taken to the operating room immediately, you may defer antibiotics to allow neurosurgery to obtain an accurate intraoperative culture.

PEARL: Spinal epidural abscess is a difficult diagnosis that you will miss if you don’t know the risk factors. If suspicious, MRI with contrast is the diagnostic test of choice; CT myelogram is insufficient.

Pediatric ECGs 

Whitney Johnson, MD, and Mimi Lu, MD

Dr. Whitney Johnson and Dr. Mimi Lu discuss pediatric ECGs and the approach to pediatric chest pain. This segment elucidates some pediatric ECG findings to be wary of and underlines important indications for ordering an ECG in children that you may not expect.

  • When to get an ECG
    • An ECG is often ordered reflexively by triage before seeing the patient.
    • Have a low threshold; seeing more ECGs will help develop interpretation skills.
    • Consider an ECG in patients with syncope, chest pain, dizziness, persistent unexplained tachycardia, recurrent febrile seizure, or epilepsy.
    • Optimize the ECG by obtaining it after fever, pain, and anxiety are controlled.
  • Interpreting Pediatric ECGs
    • The vast majority of principles from adult ECGs can be applied to children 10 or older.
      • When in doubt, use reference resources for normal values for age.
    • Axis deviation
      • Babies are born with a right axis that transitions to a normal axis at around 6 months of age. 
      • A right-deviated axis past 6 months may indicate right ventricular hypertrophy or congenital heart disease.
    • P-waves should be upright
      • Inverted P-waves may indicate an ectopic atrial tachycardia.
    • T-wave inversions
      • V1 should be upright for the first week of life before inverting.
        • Failure to invert may indicate right ventricular hypertrophy.
      • T-waves invert back to upright from 3-8 years of age and should not flip again.
      • Compare to a previous ECG to determine level of concern.
    • Narrow tachycardia is 1 of 3 things: supraventricular tachycardia (SVT), sinus tachycardia, or atrial flutter with 2:1 conduction.
    • Arrhythmia
      • Expand the rhythm strip or increase box lengths to uncover an arrhythmia.
      • The most common arrhythmia is supraventricular atrioventricular reentrant tachycardia (AVRT).
  • Approach to Pediatric Chest Pain
    • Age-appropriate questioning is key:
      • Ask about decreased exercise intolerance, feeding intolerance, cyanosis with feeding, or failure to thrive.
      • Consider myocarditis and ask about antecedent illness.
    • Consider adding a troponin when the story does not make sense; eg, teens with chest pain in the middle of the night.

PEARL: Have a low threshold to order an ECG in pediatric patients, especially in patients with syncope, chest pain, persistent unexplained tachycardia, or recurrent febrile seizure.

Critical Care Mailbag: All Things Vasopressin

Anand Swaminathan, MD, and Scott Weingart, MD

Dr. Swaminathan and Dr. Weingart discuss the mechanism, dosing, and administration of vasopressin in the ED. Their conversation covers which patients may benefit most from vasopressin and the potential future of vasopressin bolus to determine vasopressin responsiveness.

  • Mechanism of Vasopressin
    • Produced in the hypothalamus and secreted by the posterior pituitary in response to high sodium or low blood pressure
    • Acts upon the 3 vasopressin receptors:
      • V1 – Vasoconstriction
      • V2 – Antidiuretic effect
      • V3 – Adrenocorticotropic hormone release from the central nervous system
  • Dosing of Vasopressin
    • Single-agent dose is 0.01-0.06 units/minute. 
    • When combined with other agents, the maximum dose is 0.04 units/minute.
      • Higher doses are associated with ischemic complications.
  • Administration of Vasopressin
    • Two common approaches for starting vasopressin drips:
      • Add as a second-line pressor once the norepinephrine dose reaches an arbitrary threshold (0.2 μg/kg/minute or 10 μg/minute).
      • Start simultaneously with norepinephrine in patients who have liver failure, who are taking an angiotensin-converting enzyme inhibitor or angiotensin receptor blocker (ACE/ARB), or who you estimate to have been septic for ~24 hours at the time of their presentation.
    • There is no evidence showing the safety of vasopressin in peripheral lines.
    • There is new evidence suggesting that responsiveness to a bolus of vasopressin can determine which patients will benefit from a vasopressin drip.

PEARL: Consider early vasopressin administration in patients who may have vasopressin deficiency from liver failure, ACE/ARB use, or prolonged sepsis.

Ectopic Pregnancy Management

Dara Kass, MD, and Anand Swaminathan, MD

Summary: In the landscape of uncertain decision-making regarding early pregnancy and medical care, the onus falls heavily on ED physicians to deliver more holistic and complete care for these patients. Dr. Kass and Dr. Swaminathan discuss the diagnosis and management of ectopic pregnancy in the ED in our current political and legal climates.

Uncertain Landscape of Early Pregnancy Management

  • The reality is that shared decision-making as to whether a pregnant patient wants to continue a pregnancy is not available to every patient across the nation.
    • Can the patient get close follow-up ObGyn care? How fast can an ObGyn come to discuss methotrexate as a treatment option (if available)?
  • States with restrictions on medical care have fewer ObGyns available for consultation, which puts a higher burden on ED physicians. 
  • Management and care of early pregnancy used to be relatively predictable but now, with legislative changes, things have become more unpredictable.
    • ED physicians have to be sharper with our care, more informed, and very clear on what we are going to do. 

How does the value of beta human chorionic gonadotropin (beta-hCG) influence care?

  • The interpretation of an ultrasound in the context of beta-hCG value allows us to put the clinical picture together: is this an early intrauterine pregnancy (IUP)? A pregnancy of unknown location? An ectopic pregnancy?
  • The American College of Obstetricians and Gynecologists (ACOG) states that a beta-hCG level up to 3,500 mIU/mL with no IUP has zero likelihood of being a viable pregnancy.
    • It may not be an ectopic pregnancy but could be a non-viable IUP.
    • With beta-hCG in a window from 2,000 to 4,000 mIU/mL with a possible IUP, ED physicians in New York State can discuss treatment options with patients, depending on whether the pregnancy is desired or not, in addition to discussing risks of possible ectopic pregnancy.
    • Now, around the country, we are seeing that at beta-hCG levels <4,000 mIU/mL, patient choice is being removed.
      • ED physicians are now being put in a position where that decision is being pushed to later in the pregnancy, which increases our responsibility to ensure better follow-up, better communication, and better engagement with our consultants, given that risk of adverse outcomes is higher.
  • Beta-hCG <2000 mIU/mLwith no IUP = expectant management (repeat hCG, repeat ultrasound).
  • Beta-hCG >4000 mIU/mLwith no IUP = non-viable pregnancy regardless of location; patient needs treatment because if it is an ectopic pregnancy and it ruptures, the outcomes can be disastrous. 
  • Beta-hCG 2000-4000 mIU/mL (gray area) = remote possibility to have viable pregnancy, so we consult ObGyn to discuss various options with patients depending on what state and ED the patient is in.
  • We all need to make uniform decisions as emergency medicine physicians so that it is not just physicians in restricted states who are thinking about a new way to make these decisions. 

Transvaginal Ultrasound

  • If a patient has an IUP on ultrasound and hasn’t received assisted reproductive therapy, an ectopic pregnancy is functionally ruled out.
    • The risk of heterotopic pregnancy without assisted reproductive care is very low. (1:10,000)
    • If the patient is receiving assisted reproductive care, the risk of heterotopic pregnancy increases.
  • If a patient has an unruptured ectopic pregnancy, consult an ObGyn, who will review images and hCG levels and decide whether to offer the patient methotrexate or surgery.
    • These patients need additional laboratory testing and need to be admitted after administration of methotrexate to repeat beta-hCG and ensure levels are decreasing.
    • Failure of beta-hCG to decrease after methotrexate will result in a surgical procedure. 
    • If beta-hCG is decreasing on days 4 and 7 after methotrexate administration, the patient should have a weekly ObGyn appointment to repeat beta-hCG levels until they are zero.
      • In some environments in the country, that “weekly follow-up” may actually be an ED visit for a beta-hCG level because patients don’t have anywhere else to go for follow-up.
      • Access to this type of ObGyn medical care is changing around the country, and it is our job to deliver essential care to these patients if they cannot obtain it elsewhere.

Methotrexate Contraindications 

  • Renal insufficiency, immunodeficiency, active pulmonary disease, peptic ulcer disease, hypersensitivity to methotrexate, heterotopic pregnancy with viable IUP, and patients who are breastfeeding
  • Pregnancy contraindications include beta-hCG >5,000 mIU/mL or presence of fetal cardiac activity

Complications of Delaying Care

  • From the standpoint of long-term complications, offering a patient methotrexate as a treatment modality for an ectopic pregnancy is different from offering a patient surgery. 
  • Abdominal surgery means the patient will lose a fallopian tube and will be admitted to the hospital for a period of time, and it can affect fertility.
  • If we don’t act early or we delay care for our own legal protections, we limit our patient’s treatment options and can cause long-term complications.
  • The medico-legal climate is changing surrounding ectopic pregnancy care and, unfortunately, by discharging a patient who has an untreated ectopic pregnancy, you may run the risk of an Emergency Medicine Treatment and Labor Act (EMTALA) violation.

Administration of Rhogam 

  • The new ACOG recommendations still recommend administration of Rhogam in a patient with an ectopic pregnancy who is Rh negative, actively bleeding, and at less than 12 weeks’ gestation.
  • A patient who is not bleeding and who is terminating a pregnancy for whatever reason (including ectopic pregnancy and elective terminations) does not require Rhogam.

PEARL: The medicine of ectopic pregnancy management has not changed; rather, changes in access to medical care, unevenness of care, and the current political and legal landscape surrounding pregnancy termination are challenging us as emergency medicine physicians. The onus is on us to be our patients’ advocates in the different environments in which we encounter and treat these patients across the country.

Hyponatremia: Are we all doing this wrong?

Ayus JC, Moritz ML, Fuentes NA, Mejia JR, Alfonso JM, Shin S, Fralick M, Ciapponi A. Correction Rates and Clinical Outcomes in Hospitalized Adults With Severe Hyponatremia: A Systematic Review and Meta-Analysis. JAMA Intern Med. 2024 Nov 18:e245981. doi: 10.1001/jamainternmed.2024.5981. PMID: 39556338

Bottom line: This meta-analysis of observational data shows an association between slower sodium correction in severe hyponatremia and increased mortality. These results are not definitive, but considering the rarity of demyelination, and the magnitude of the mortality results, this should probably influence clinical practice until we get the proper RCTs.

Nice graphic from the nephrology journal club as a nice overview of hyponatremia management:

Clinical Conundrum: Should Acute Asthma Exacerbations Be Discharged From the ED With Combination Beta Agonist/Corticosteroid Inhalers?
  • Written by Steve Orellana DO,REBEL Core, REBEL EM
  • Bottom Line: Current research suggests we should replace prescriptions for a SABA inhaler (i.e. albuterol) with a LABA-ICS combination inhaler as it can be used both for maintenance therapy and as a rescue inhaler. Furthermore, Budesonide + Formoterol is a safe patient-centered option that is at least as effective, if not better, than SABA alone. This change does not alter the recommendation of treating with a systemic steroid (ie dexamethasone, prednisone etc). The practice of discharging a patient with SABA inhalers alone should be ended.
  • Prescription: Budesonide/formoterol 80/4.5 μg/puff, 1-2 puffs once to twice daily for maintenance, and then 1-2 puffs every 2-4 hours as needed for asthma symptoms, with instructions to go to the ED if more than that is required.

D-Dimer in High-Risk PE: A Gamble Worth Taking?

Author Conclusion: “In this study, ruling out pulmonary embolism in high-risk patients based on D-dimer below the age-adjusted threshold was safe, with no missed pulmonary embolism. However, the sample size was not large enough to draw a definitive conclusion on the safety of this strategy.”

Clinical Take Home Point: It may be reasonable to consider forgoing CTPA imaging in high-risk PE patients if they have a negative D-dimer, but more research that is prospective with larger cohorts is needed to determine the safety of this approach

Clinical Effects of Psychedelic Substances Reported to United States Poison Centers: 2012 to 2022

  • Hallucinogenic amphetamines (MDMA), lysergic acid diethylamide, tryptamines (such as N, N-dimethyltryptamine), phencyclidine, hallucinogenic mushrooms, hallucinogenic plants, and ketamine and ketamine analogs. Over half of psychedelic exposures reported to US poison centers had symptoms that required treatment, severe residual or prolonged symptoms, or death. Increases in psychedelic use may lead to increased frequency of adverse events and health care utilization.

ACEP Clinical Policy: Critical Issues in the Evaluation and Management of Adult Out-of-Hospital or Emergency Department Patients Presenting With Severe Agitation

  • Is there a superior parenteral medication or combination of medications for the acute management of adult out-of-hospital or emergency department patients with severe agitation?
    • Level A recommendations. None specified.
    • Level B recommendations. For more rapid and efficacious treatment of severe agitation in the emergency department, use a combination of droperidol (5mg) and midazolam (2.5mg IM or IV if <50kg, 5mg if >50kg) or an atypical antipsychotic, olanzapine (5mg IM/IV) in combination with midazolam (2.5mg IM or IV if <50kg, 5mg if >50kg). If a single agent must be administered, use droperidol or an atypical antipsychotic (olanzapine) due to the adverse effect profile of midazolam alone.
    • Level C recommendations. In situations where safety of the patient, bystanders, or staff is a concern, consider ketamine (intravenous or intramuscular) to rapidly treat severe agitation in the ED (Consensus recommendation).
  • No recommendations for or against the use of specific agents in the out-of-hospital setting can be made at this time (Consensus recommendation).
  • No recommendation for or against the use of specific agents in patients above the age of 65 years can be made at this time (Consensus recommendation).

Clinical Policy: Use of Thrombolytics for the Management of Acute Ischemic Stroke in the Emergency Department

Managing Emergency Endotracheal Intubation Utilizing a Bougie

  • Advantages when used with standard geometry laryngoscopy:
    • improved field of view as the bougie approaches the glottis compared to a larger ETT
    • narrower profile also beneficial for airway edema, epiglottis
  • Disadvantages
  • Procedure
    • Preparation
      • Curve the bougie using the “snail tail” technique. Curving may reduce the need to remove the bougie and reshape it later if the trachea cannot be cannulated on the first attempt with a straight bougie.
      • Grip
        Utilizing a right-handed “tripod” grip proximal to the midpoint of the bougie (Figure 5) allows the middle finger that is behind/under the bougie to apply leverage, which may facilitate microadjustments of the coudé tip.
      • Operators should look into the mouth as the bougie is inserted and not the screen if video laryngoscopy is utilized. If curved, the bougie can be inserted at the midline alongside the curve of the laryngoscope (Figure 6) with a rotational motion that brings the coudé tip toward the glottis. The coudé tip is angled anteriorly as it passes through the cords.
      • If kept straight, the bougie should be inserted initially at the corner of the mouth.
      • If the coude hangs up at the tracheal cartilage rotate clockwise.
      • Advancement can cease once the black line (23 cm) is even with the teeth or if “hold up” occurs.
      • The ETT should be advanced over the bougie past the corner of the mouth to the glottis. As the bevel tip approaches the glottis, it should be intentionally rotated 90° counterclockwise and advanced into the trachea to the proper depth. Counterclockwise rotation directs the ETT bevel posteriorly, which avoids hang-up on the arytenoids
    • Troubleshooting
      Challenges with advancing the bougie or the ETT exist, but operators should employ the following maneuvers if experiencing difficulty.21 Failing to respond appropriately to these challenges has been described as distinct performance errors noted during standard geometry video laryngoscopy.22
      • Bougie Hang-Up
        If the coudé tip becomes stuck on the anterior tracheal rings despite optimal vallecula manipulation, there are remedies. Continuing to hold the bougie’s shaft, operators should discontinue forward pressure and apply a 90° rotation to release the coudé tip and allow advancement. If rotation fails, the operator can move to the proximal end of the bougie and employ a “twirl” technique that will transfer rotational forces to the coudé tip and release it from the tracheal rings.
      • ETT Hang-Up
        If the ETT cannot be advanced through the glottis over the bougie, it is often stuck on the arytenoids. Operators should halt forward pressure, pull back slightly on the ETT, and rotate the ETT bevel tip 90° counterclockwise to the 12 o’clock position in the tracheal opening before advancing into the trachea.
      • Loss of View Due to Premature Removal of Laryngoscope
        Operators may hastily remove the laryngoscope before visualizing the ETT going through the cords over the bougie. This causes the tongue and oropharyngeal structures to collapse posteriorly and can potentially inhibit ETT delivery. If this occurs, operators should re-establish the view first instead of withdrawing the ETT or bougie (Video E13, available at http://www.annemergmed.com).

Cardiology Corner: Asymptomatic QTc Prolongation

Amal Mattu, MD, and Anand Swaminathan, MD

Amal and Swami discuss QTc prolongation. We all know what to do with patients who present to our ED with a syncopal episode in the setting of a prolonged QT, but what about QT prolongation in asymptomatic patients? Listen as they discuss how to manage the asymptomatic patient with QT prolongation.

  • Why is a prolonged QT in the setting of syncope clinically significant?
    • The danger of the prolonged QT in syncope is torsade de pointes
    • Differential: hypocalcemia, hypokalemia, hypomagnesemia, congenital long QT syndrome, or medication side effect
    • Disposition: admit patients with prolonged QTc to a telemetry bed in the setting of syncope
  • Definition of a prolonged QTc interval:
    • In men, corrected QT interval >440 msec
    • In women, corrected QT interval >460 msec
    • The corrected QT interval adjusts for QT length at heart rate extremes. The most accurate QTc calculation is between heart rates of 60 to 100 beats per minute.
  • At what QTc should we begin to worry about torsade?
    • Increased risk for torsade begins at >500 msec.
    • We do not need to calculate the QTc manually. The QTc provided by an ECG is reliable in the absence of artifact.
      • Consider calculating the QT in specific cases such as drug overdoses or ECGs with artifact.
  • How should we be managing asymptomatic patients (ie, those not presenting with syncope and those without a family history of sudden cardiac death) with a prolonged QT?
    • There is no standard of care. 
    • Amal recommends the following:
      • Check electrolytes and, if possible, correct abnormal findings.
      • Perform a thorough medication history and address changes of medications with the patient’s primary care provider (PCP) or do so yourself in the ED.
      • If incidental finding without a discernible cause, then be sure to recommend follow-up for prolonged QTc with PCP. 
  • How soon should patients follow up when they are discharged with an incidental finding of a prolonged QT?
    • There is no current standard of care. Consider changing the urgency of follow-up based on the QT interval. A QT interval of 600-700 may need an urgent follow-up in 1-2 days, as opposed to routine follow-up for QTs in the 500 range.
    • Asymptomatic patients with a prolonged QT should be discharged irrespective of the length of the QT. Be sure to arrange follow-up or consult cardiology to arrange prompt follow-up for extremes.
  • How can we better manage patients with a prolonged QT who are chronically on QT-prolonging medications?
    • If the QT >600 msec, or if there has been a rapid rise in a patient’s QT, then consider calling their PCP and coordinating changes to their medications. 
    • If prescribing new medications, remember that we often prescribe QT-prolonging agents (eg, ondansetron, prochlorperazine, quinolones).
      • Avoid putting patients at higher risk of torsades. Look for alternative medications or avoid QT-prolonging medications altogether.
        • Consider benzodiazepines or scopolamine patches for nausea.
        • Consider cephalosporins instead of quinolones.
        • Consider metoclopramide (Reglan) instead of ondansetron (Zofran) or haloperidol (Haldol), as it has less of a QT-prolonging effect.
  • Should we order an ECG before giving haloperidol to acutely agitated patients?
    • This is not necessary. The benefit of sedating a patient who is agitated and a danger to themselves and staff outweighs the risk of QT prolongation with haloperidol or droperidol.
    • Get an ECG if the patient requires repeat doses.
    • Summary:
      • Managing asymptomatic patients with a prolonged QT is not as clear cut as managing patients presenting with syncope. Remember our commonly used QT-prolonging medications, and consider alternative treatments for complaints such as nausea, migraines, and infections. Finally, be sure to arrange close follow-up for patients being discharged with this common incidental finding. 

Phenobarbital dosing for the treatment of alcohol withdrawal syndrome: a review of the literature Brooks L, Reinert JP. J Pharm Technol. 2024;40(4):186-193.

SUMMARY:

  • Despite growing interest in phenobarbital as an alternative for ED treatment of alcohol withdrawal in both clinical and research settings, most ED practitioners still rely on benzodiazepines as a first-line therapy. However, the culture may be changing, as we recently covered the Guidelines for Reasonable and Appropriate Care in the Emergency Department (GRACE-4) on the topic of ED management of nonopioid use disorders. In the section on alcohol withdrawal syndrome, the authors favored phenobarbital.
  • Phenobarbital is a barbiturate with a dual mechanism of action and an affinity for both GABA and glutamate receptors, whereas benzodiazepines have affinity toward only GABA. This dual affinity underlies phenobarbital’s unique mechanism of action, which differs from those of even other shorter-acting barbiturates. Phenobarbital has been studied and used effectively in both emergency and ICU settings. It has a rapid onset of action, at approximately 15 minutes, and an extremely long duration of action, thus enabling less frequent dosing.
  • Because many ED providers have never used phenobarbital, the authors conducted a comprehensive literature review to describe and elucidate the best dosing strategies to aid in personal practice or in the development of new hospital guidelines regarding phenobarbital use.
  • The review included articles describing clinical outcomes, complete dosing strategies, and adverse effects related to the use of phenobarbital for alcohol withdrawal, and excluded articles that could not differentiate the effects of phenobarbital vs another medication. Six articles met the inclusion and exclusion criteria: 4 using a fixed-dose approach, and 2 comparing weight-based vs fixed dosing. In general, the fixed-dose approach involved initial administration of 260 mg, with an option for additional doses every 15 to 30 minutes, with a maximum of 4 doses in the ED. The average number of doses administered was approximately 3, and clinical outcomes were positive, including discharge rates comparable to those with other agents. In the studies examining weight-based vs fixed dosing, no differences were observed in ICU length of stay; mortality; or adverse events, including respiratory depression/failure or hypotension.
  • Across all trials, the message is clear that phenobarbital was used safely and effectively.
  • The authors are forthright regarding the limitations of their systematic review, including the small total number of studies, heterogeneous outcome assessment measures, and variations in the total medication amounts given. The goal was not to change practice but to provide information and a literature summary for physicians who might want to try a new protocol.
  • PMID: 39157637
  • EDITOR’S COMMENTARY: In this systematic review, the authors reviewed 6 identified papers to make the point that phenobarbital use in the ED for alcohol withdrawal syndrome is both safe and effective. The authors suggest that hospital administrators should use the findings to create new protocols for the management of alcohol withdrawal. Given that the new GRACE-4 guidelines also include phenobarbital, we might actually see these protocols get developed. If you have never tried it, 260 mg IV is a good first dose for most adults, and you should reevaluate in approximately 15 to 30 minutes. It does work and might even be better than benzos for some outcomes.

WOMAN-2: TXA has no role in postpartum hemorrhage

  • The WOMAN 2 trial is a large double-blind RCT that shows no benefit of TXA in the prevention of postpartum hemorrhage, which fits with all of the existing literature demonstrating no role for TXA in the management of postpartum hemorrhage. We still cannot comment on the role of TXA in massive post-partum hemorrhage, as none of the research to date has really captured that group of patients.

A Randomized Controlled Comparison of Guardian-Perceived Cosmetic Outcome of Simple Lacerations Repaired With Either Dermabond, Steri-Strips, or Absorbable Sutures. Pediatr Emerg Care. 2024 Aug 15.

  • I have a long series of articles looking at the science behind laceration repair, and I think the simplest answer is: nothing you do matters. Or, if you don’t like that level of nihilism, you could phrase it as, the human body has amazing mechanisms to repair the skin, and our job is mostly to set the natural healing up for success (aka get out of the way). This is an RCT from a single pediatric emergency department, randomizing children with small linear lacerations (less than 5 cm long, less than 5 mm gap, and less than 12 hours old) to dermabond, steri-strips, or absorbable sutures. The primary outcome was cosmetic appearance as rated by the child’s parent at 3 months. They include 55 patients, and three groups had statistically similar outcomes (although the dermabond group was rated 15 points higher on the visual analog scale, which might be clinically significant, and so this tiny study is just too tiny.) Likewise, although none of the secondary outcomes were statistically significant, the point estimates look worse for sutures in length of stay, pain, and overall satisfaction. At the end of the day, this trial doesn’t add much, because they only enrolled small linear lacerations, and we already knew that these healed no matter what you do. (Honestly, most of the lacerations in this study with a median length of 1.5 cm would have probably had the same outcome with a bandaid). At this point, I have almost entirely abandoned sutures in my practice. Dermabond and/or steristrips will close more than 95% of the lacerations we see.
    • Bottom line: This tiny single center trial doesn’t add a lot, but gives me another opportunity to pitch abandoning sutures to you. You will be more efficient, cause less pain, have happier patients, and your outcomes will be identical.

Predictors of Laryngospasm During 276,832 Episodes of Pediatric Procedural Sedation

  • Laryngospasm occurs in 3.3/1000 cases of Ketamine
  • Among patients with laryngospasm, the resulting outcomes included desaturation less than 70% for more than 30 seconds (19.7%), procedure not completed (10.6%), emergency airway intervention (10.0%), endotracheal intubation (5.3%), unplanned admission/increase in level of care (2.3%), aspiration (1.1%), and cardiac arrest (0.2%).

Pediatric Procedural Sedation and Laryngospasm: How Much Should I Worry?

  • Laryngospasm is rare—approximately 3 in 1,000 sedations performed outside the operating room, and this number may even be lower in the ED setting.
  • Serious outcomes are very rare but do occur.
  • Risk factors to be aware of are as follows: young age (<1 year), patients with upper respiratory tract infections, patients categorized as ASA class III or higher, procedures involving the upper airway, and sedation with a combination of ketamine and propofol. It is uncertain whether these factors are directly translatable to ED sedations; however, knowing these patient- and medication- related risk factors can help inform emergency physicians in
  • sedation planning.
  • The findings of Cosgrove et al1 support continued confidence in ketamine as a single agent to provide safe and effective sedations for children.
  • Laryngospasm associated with procedural sedation is a rare event regardless of the clinical setting, drug administered, or procedure performed—however, the risk is not zero—reinforcing that all sedation clinicians must be skilled in airway rescue.
  • .48% incidence of invasive bacterial infection among 2-6 month olds with fever.
  • Only 4 positive CSF cultures (1/5250).

Laceration evidence part 7: Aftercare instructions

  • Can wounds get wet?
    • Very low level of evidence, but it is probably safe to get wounds wet early after repair, and keeping them clean with soap and water makes physiologic sense.
  • Do dressings help?
    • There does not seem to be any evidence that dressings improve healing after acute lacerations. It makes sense to use a dressing for comfort, and to absorb blood and exudate in the first 12-24 hours after repair. Obviously, patients can continue to use dressings for aesthetic or comfort reasons if they prefer.

For such a common problem in emergency medicine, there is a striking paucity of evidence to guide our care of lacerations. Nothing I found allowed for definitive conclusions, so clinical judgment and shared decision making are, like always, necessary.

Personally, I tell patients:

  • A dressing isn’t required, but you probably want one for the first 24 hours, as some bleeding may still occur. After that point, I would suggest applying a dressing if you are in an environment where the wound might become contaminated, or if you prefer one for cosmetic sake, but I want you to remove the dressing every day to check for signs of infection.
  • It is fine to get the wound wet, and in fact I like the idea of keeping the area clean with soap and water. However, I would avoid obviously contaminated water sources, like lakes and public pools until the wound is completely healed.
  • Topical antibiotics probably aren’t necessary. They might prevent small pimple-like infections, but there is a risk of an allergic reaction. You can use an over-the-counter preparation if you like. 
  • I don’t think there is any evidence that vitamin E or expensive scar creams help. Applying a very light layer of vaseline during the first week, to keep the wound moist as it heals, might make sense.

Dose VF: A double sequential defibrillation game changer?

  • Study in NEJM looked at out of hospital arrest with refractory vfib or pulseless Vtac after 3 failed attempts at defibrillation.
  • Commentary by First10em:
    • It has never made any sense to continue to provide the same unsuccessful therapy over and over again, so I think all of us have been changing something after 3 unsuccessful shocks, whether it was simply changing pad position, or adding a second machine. 
    • Working in a community hospital without access to ECMO or the cath lab, if I have a patient in refractory ventricular fibrillation after 3 shocks, I will perform one of these techniques, but that actually isn’t a change from current practice. I think the plan that might make the most sense is to apply a new set of pads in the anterior-posterior position after the 3rd unsuccessful shock, provide one vector change shock (to limit the risk of machine damage while still gaining potential benefit), and then if that didn’t work try double sequential for the next attempt. I think the potential benefit is worth the relatively limited risk in a hospital setting.
    • However, I will continue to emphasize that this is not standard of care, and this is not definitely proven, and we definitely need to see follow-up RCTs.

Association between advanced image ordered in the emergency department on subsequent imaging for abdominal pain patients

  • Results: Of the 1385 ED visits with abdominal pain chief complaint and discharged home from the ED, individuals who were not imaged in the ED had significantly higher adjusted odds of being imaged outside the ED within 7 days (adjusted odds ratio [aOR] 6.65, 95% confidence interval [CI] 3.96–11.17, p < 0.001), 14 days (aOR 4.69, 95% CI 3.11–7.07, p < 0.001), and 28 days (aOR 3.1, 95% CI 2.25–4.27, p < 0.001) of being discharged and had a significantly higher adjusted odds of revisiting the study ED (aOR 1.65, 95% CI 1.29–2.12, p < 0.001) and revisiting any ED (aOR 1.47, 95% CI 1.16–1.86, p = 0.001) within 30 days of being discharged.
  • Conclusions: Abdominal imaging in the ED was associated with significantly lower imaging utilization after discharge and 30-day revisit rates, suggesting that imaging in the ED may replace downstream outpatient imaging.

Intranasal Topical Application of Tranexamic Acid in Atraumatic Anterior Epistaxis: A Double-Blind Randomized Clinical Trial

Can’t Stop, Won’t Stop: The Return of Tranexamic Acid for Epistaxis

  • Therefore, it is likely that the tranexamic acid literature will continue to evolve, and tranexamic acid should be seen not as a cure-all hemostatic agent but, rather, as a specific tool with unique benefits and limitations. However, in light of this present study and the existing literature, we believe that it is reasonable to use tranexamic acid in patients presenting to the ED with epistaxis given that it is a low-cost, relatively painless intervention that may prevent the discomfort of anterior nasal packing. Future studies should identify the populations that receive the greatest benefit and the role for newer technology (eg, viscoelastic testing to determine whether hyperfibrinolysis is present) to guide antifibrinolytic therapy.

Non-sterile gloves and dressing versus sterile gloves, dressings and drapes for suturing of traumatic wounds in the emergency department: a non-inferiority multicentre randomised controlled trial

  • Results From 2468 eligible patients, 1480 were randomised in a sterile (n=747) or non-sterile (n=733) protocol. Baseline characteristics were similar in both study arms. The observed wound infection rate in the non-sterile group was 5.7% (95% CI 4.0% to 7.5%) vs 6.8% (95% CI 5.1% to 8.8%) in the sterile group. The mean difference of the wound infection rate of the two groups was −1.1% (95% CI −3.7% to 1.5%).
  • Conclusion Although recruitment ceased prior to reaching our planned sample size, the findings suggest that there is unlikely to be a large difference between the non-sterile gloves and dressings for suturing of traumatic wounds and sterile gloves, dressings and drapes for suturing of traumatic wounds in the ED.

    • Can be still be replaced if <7-10d old (mature) but use more caution, ENT consult if time permits, ideally use flexible endoscope, if none then use a bougie.
    • Replacement of a Trach with a mature track can be done blindly, assisted by a bougie, or with a flexible endoscope.

EMCrit 329 – Bariatric Critical Care and Resus Ready for the Super Obese Patient

  • BP- can be falsely high because cuff is too small, can try calf but unknown if this is studied, Scott recommends an art line
  • CPAP preox
  • Positioning (see pics below): line up external auditory meatus with the sternal line not notch, meaning need to line up with the line from the sternal notch to diploid process.
  • Avoid RSI in severely obese patients, DSI safer unless the patient is apneic.
  • Intubation Meds
    • Etomidate LBW LBW calculator
    • Ketamine LBW
    • Propofol TBW for drip
    • Succinylcholine TBW
    • Rocuronium- Some would say IBW, but Calvin Brown [UpToDate in the Biblio] and The EM Airway Course is recommending TBW–That is my rec as well
  • DSI approach (per Scott): start with Ketamine 100mg and wait ten seconds, if patient not dissociated give more, this allows you to take a look, if intubation looks easy then redox and paralyze because DSI easier for looking then for passing a tube
    • Post-intubation positioning- sitting up so pannus not preventing chest expansion
  • Central line- neck or groin better, subclavian has no landmarks

PulmCrit – Myth-busting the conditional nephrotoxicity of piperacillin-tazobactam

  • Piperacillin-tazobactam is not generally regarded as a nephrotoxin although it can rarely cause acute tubulointerstitial nephritis, an unusual allergic reaction seen with numerous antibiotics/other meds.
  • Vancomycin is an actual nephrotoxin.
  • Solution:
    • Continue to use Piperacillin-tazobactam
    • Avoid Vanco in non-MRSA situations (community acquired-urosepsis/intra-abdominal infections, non purulent cellulitis)
    • Discontinue after 24-48 hours if negative MRSA nares PCR and negative blood culture)
    • Dose Vanco carefully, monitor levels
    • Consider Linezolid or Daptomycin over Vanco for patients at high risk of nephrotoxicity

Critical Care Mailbag: Critical Transfusions- Weingart

  • Type is ABO group
  • Screen evaluates if the patient has any of the common minor antibody groups (such as Rh, Kelly, Duffy).
  • Crossmatch”: takes blood that matches the patient for both major and minor antibody groups and reserves it for the patient, essentially taking it out of the pool of available blood.
  • Take Home #1: There is no need to routinely obtain Type + Cross on every patient who may need blood.
  • If the patient screens “negative” for any minor antibody groups, crossmatch is unnecessary.
  • If the patient needs immediate transfusion (eg, in the event of massive GI bleed or trauma with shock), you can transfuse without knowing the minor antibody groups.
  • If the patient screens “positive” for minor antibody groups, crossmatch can be helpful in ensuring compatible blood is available.
  • Take Home #2: Every hospital should have a system where the blood bank notifies the clinician when the patient screens positive for minor antibodies
  • In this situation, taking a number of units out of circulation is important to ensure that when the patient with minor antibodies needs a transfusion, they have the right blood available.

MTP

  • In most hospitals, massive transfusion protocol is the only way to rapidly get blood.
    However, this approach is often more than is needed and can be wasteful as it utilizes a lot of resources and can shut the blood bank down to other patients.
  • Many bleeding patients will stabilize after 1-2 units making massive transfusion protocol unnecessary.
  • An intermediate pack can be considered
    These are immediate-release “universal donor” blood products. Scott recommends the pack consists of 2 units pRBCs and 2 units FFP.

Topical TXA in Atraumatic Anterior Epistaxis Yet Again

  • Paper: Hosseinialhashemi M et al. Intranasal Topical Application of Tranexamic Acid in Atraumatic Anterior Epistaxis: A Double-Blind Randomized Clinical Trial. Ann Emerg Med 2022. 
    • Clinical Take Home Point: Based on this trial and the systematic review published in 2021 (Link is HERE), the fact that topical TXA is low cost, simple to use, and has no untoward effects it seems the best 1st line strategy in epistaxis is a TXA soaked pledget with direct pressure. It is unclear whether TXA has benefit in cases where compression with a topical vasoconstrictor fails.

The CLASSIC Trial: IV Fluid Restriction in Septic Shock

Clinical Take Home Point: In critically ill adult patients with septic shock who received their initial 30cc/kg fluid resuscitation there are two ways to look at ongoing resuscitation based on this trial:

  1. Restrictive fluid strategy ≠ fewer deaths at 90 days than standard fluid therapy
  2. Restrictive fluid strategy is not worse than standard fluid therapy in terms of fewer deaths at 90 days (i.e. Safe but not superior to a standard fluid strategy)

A major caveat however is the between group differences of overall fluids given at 5 days (≈1500cc) and the rather small difference in fluid balance between groups (≈750cc) has to make one wonder how much standard care has changed to more of a conservative strategy overall in terms of fluid balance.

Antibiotics in COPD Exacerbations – 2 days vs 7 days

  • Authors Conclusions: “Levofloxacin once daily for 2 days is not inferior to 7 days with respect to cure rate, need for additional antibiotics and hospital readmission in AECOPD. Our findings would improve patient compliance and reduce the incidence of bacterial resistance and adverse effects.”
  • Our Conclusions: We agree that this study demonstrates non-inferiority of a 2-day course of levofloxacin to a 7-day course. However, the trial has a number of issues including the subjectivity of the outcome measure which may bias the results. Subsequent studies should focus on generating high-quality data looking at short-course antibiotics versus no antibiotics.
  • Bottom Line: It remains unclear if mild to moderate AECOPD benefit from antibiotics but, if you are going to prescribe them, a short course appears to be adequate.
  • Uptodate: Recommends 3-5 days of antibiotics Augmenting or Levaquin

Tenecteplase vs Alteplase in Acute Ischemic Stroke

Why Tenecteplase over Alteplase:
  • Cheaper
  • Higher fibrin specificity
  • Can be administered as a single bolus (due to longer half-life than alteplase)
  • Allows for more rapid treatment without the need for infusion pumps

EPIC Trial: Electrode Positioning in Cardioverting Atrial Fibrillation

  • Escalating energy shocks of 100 Joules, 150 J, 200 J and 360 J were delivered until sinus rhythm was restored or a up to a maximum of 4 shocks
  • Comparison of Anterior Posterior vs Anterior Lateral
  • Risk difference after final shock for obese patients was 15 percentage points (95% CI, 5-25) with a risk ratio of 1.2 (95% CI, 1.05 – 1.36). For non-obese patients, the risk difference after the final shock was 3 percentage points (95% CI, -3 to 9) with a risk ratio of 1.03 (95% CI, 0.96 to 1.10)
  • Although this multicenter, randomized, open-label, blinded-outcome trial had a very different patient population than those typically seen in the emergency department, strong consideration should be made in placing the pads in the anterior-lateral positioning during cardioversion. Doing so may very well reduce the number of shocks needed to convert stable atrial fibrillation patients to normal sinus rhythm.
