Episode 868: Airway Management in Obesity show art Episode 868: Airway Management in Obesity

Emergency Medical Minute

Contributor: Aaron Lessen MD Educational Pearls: Why is airway management more difficult in obesity? Larger body habitus causes the chest to be above the head when the patient is lying supine, creating difficult angles for intubation. Reduced Functional Residual Capacity (FRC) causes these patients to deoxygenate much more quickly, reducing the amount of time during which the intubation can take place. What special considerations need to be made? Positioning. The auditory canal and sternal notch should be aligned in a horizontal plane. Do this by stacking blankets to lift the neck and...

Episode 867: Occult Scaphoid Fractures show art Episode 867: Occult Scaphoid Fractures

Emergency Medical Minute

Contributor: Nick Tsipis MD Educational Pearls: The scaphoid bone is the most proximal carpal bone just distal to the radius Fractures of the scaphoid bone are sometimes missed by plain X-rays A 2020 review found a 21.8% incidence of missed scaphoid fractures later diagnosed by advanced imaging modalities Only MRI has a sensitivity above 90% for diagnosing scaphoid fractures Sensitivity of plain-film radiography is low unless it is a displaced fracture Physical examination techniques fail to definitively rule out scaphoid fractures A 2023 systematic review assessed the...

Podcast 866: Carbamazepine (Tegretol) Overdose show art Podcast 866: Carbamazepine (Tegretol) Overdose

Emergency Medical Minute

Contributor: Aaron Lessen MD Educational Pearls: What is Carbamazepine (Tegretol)? Carbamazepine is an anti-epileptic drug with mood-stabilizing properties that is used to treat bipolar disorder, epilepsy, and neuropathic pain. It functions primarily by blocking sodium channels which can prevent repetitive action potential firing. What are the symptoms of an overdose? Common initial signs include diminished conscious state, nystagmus, ataxia, hyperreflexia, CNS depression, dystonia, and tachycardia Severe toxicity can cause seizures, respiratory depression, decreased myocardial...

Podcast 865: Nausea Treatments - Droperidol vs Ondansetron RCT show art Podcast 865: Nausea Treatments - Droperidol vs Ondansetron RCT

Emergency Medical Minute

Contributor: Aaron Lessen MD Educational Pearls: A recent randomized controlled trial compared ondansetron 8 mg IV with droperidol 2.5 mg IV for the treatment of nausea & vomiting in the emergency department.  Overall, droperidol and ondansetron had similar primary outcomes in acute nausea control  Symptom improvement in 93% of patients receiving droperidol vs. 87% receiving ondansetron (P = 0.362) Secondary measures were, however, statistically significantly different between groups Patients needed fewer rescue/additional antiemetics in the droperidol group (16%)...

Podcast 864: Arterial Blood Gas (ABG) vs Venous Blood Gas (VBG) show art Podcast 864: Arterial Blood Gas (ABG) vs Venous Blood Gas (VBG)

Emergency Medical Minute

Contributor: Aaron Lessen MD Educational Pearls: What is measured in an ABG/VBG? Blood values for oxygen tension (pO2), carbon dioxide tension (pCO2), acidity (pH), oxyhemoglobin saturation, and bicarbonate (HCO3) in either arterial or venous blood Other tests can measure methemoglobin, carboxyhemoglobin, hemoglobin levels, base excess, and lactate What are they used for? Identification of ventilation/acid-base disturbances. For example: if a patient is in septic shock, oxyhemoglobin saturation can be used to guide resuscitation efforts (early goal- directed therapy) What's the...

Contributor: Aaron Lessen MD Educational Pearls: Patients with alcohol use disorder are frequently discharged from the ED without further resources Pharmacological treatments to reduce cravings in AUD exist Naltrexone  Effective at reducing alcohol cravings and heavy drinking  Gabapentin Reduces the percentage of heavy drinking days in AUD Patients being discharged from the ED should be asked if they feel their alcohol use is a problem, which can further direct appropriate pharmacological interventions References 1.

Podcast 862: How to Apply a Painful Stimulus show art Podcast 862: How to Apply a Painful Stimulus

Emergency Medical Minute

Contributor: Travis Barlock MD Educational Pearls: When might you need to apply a painful stimulus in a medical setting? The main reason is to assess the patient's level of consciousness, such as when they are waking up from anesthesia or have potentially suffered a brain injury. It can be part of the Glasgow Coma Scale (GCS) if patients are not responding to auditory stimuli. Possible levels of consciousness include Alert, Lethargic, Obtunded, and Comatose (ALOC) What are the approved ways to apply a painful stimulus to assess central nervous system function? Trapezius squeeze. Grab...

Podcast 861: Alcohol Withdrawal and Delirium Tremens show art Podcast 861: Alcohol Withdrawal and Delirium Tremens

Emergency Medical Minute

Contributor: Travis Barlock MD Educational Pearls: Alcohol binds the GABA receptor, which produces an inhibitory response, hence the “depressive” effects of ethanol beverages. Over time, alcohol downregulates the GABA receptors, leading to unopposed glutamate activity. Given that glutamate is excitatory, this can lead to seizures. Alcohol also suppresses REM sleep; in patients with chronically suppressed REM sleep, the brain starves for dream sleep and it spills over into the wakeful state, inducing a dream-like state when someone is awake. The awake dream-like state of delirium...

Educational Pearls:

  • Insulin pumps provide a continuous infusion of fast-acting insulin using a basal rate and bolus prior to meals
  • Some connect to a continuous glucometer but often blood glucose needs to be checked manually
  • Hypoglycemia is rarely due to a malfunctioning pump - there is usually an another external factor
  • Hyperglycemia can be caused by underdosing, illness, pump malfunction or expired insulin
  • The pump can be used to give a bolus of insulin in the emergency department if necessary
  • Stopping the  device can be done manually on the device or disconnecting it from the tubing attachment - do not remove the tubing from the skin site if possible
