An abnormal upper lip bite test, in which the patient’s lower incisors cannot extend to reach the upper lip, increases the probability of a difficult intubation from 10% to greater than 60%.

A standard 5cm 14-16 gauge needle for chest decompression was more than twice as long as needed for children < 13 years old based on CT chest wall thickness (CWT).

Alex Chen goes in depth with this toxicology myth-bust on the risk of exposure to fentanyl or fentanyl analogs to prehospital personnel.

Prehospital double sequential defibrillation was not associated with improved survival for out-of-hospital cardiac arrest patients with refractory ventricular fibrillation or pulseless ventricular tachycardia.

The European Resuscitation Council International Liaison Committee on Resuscitation 2018 guideline has made one minor change regarding antiarrhythmic drugs in arrest: lidocaine, in place of amiodarone, is now a viable, equally effective option in patients with VF/pVT refractory to defibrillation.

There was no difference in an endotracheal tube vs supraglottic airway for patients with out-of-hospital cardiac arrest in the outcomes of return of spontaneous circulation, survival to admission, survival to discharge, or survival with good neurological outcome in studies with low risk of bias in this large metaanalysis.

Prehospital use of tourniquets (TQ) for extremity trauma markedly reduced transfusion requirement and likely also reduced the need for fasciotomy or amputation.

Double sequential defibrillation means hooking up two external defibrillators and discharging them simultaneously in patients with refractory ventricular fibrillation (v-fib). What could possibly go wrong?

Video laryngoscopy gets the green light from Academic Emergency Medicine over direct laryngoscopy - clear benefit, no harm. For every 17 intubations using VL, one less patient will have a failed intubation.

When considering 14 RCTs on use of antiarrhythmic drugs for shockable cardiac arrest, there was no benefit for survival to discharge or survival with good neurological outcome. Lidocaine improved ROSC vs placebo.
