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...

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.

Educational Pearls:
- Tramadol is often thought of as a mild-opiate to use for analgesia, but it is a more complicated drug
- Tramadol needs to be metabolized into an effective drug making it not pharmacologically reliable
- 3-10% of people cannot metabolize tramadol and it does not work
- Some others over-metabolize tramadol and it causes greater effect
- Studies have shown it is not any better as a acetaminophen or ibuprofen for analgesia, it can lower a seizure threshold, and it acts to inhibit serotonin reuptake
- Recent study evaluated all-cause mortality of tramadol compared to codeine and found tramadol had nearly double the all-cause mortality as those prescribed codeine
- Overall tramadol has many risks and should be critically evaluated before prescribing
