Prehospital use of tourniquets (TQ) for extremity trauma markedly reduced transfusion requirement and likely also reduced the need for fasciotomy or amputation.
It is estimated that to place an endotracheal tube (ETT) successfully in 30-60 seconds, using direct laryngoscopy, would take 3-5 years of experience and 137-243 endotracheal intubations (ETI). Increased experience did not reduce the time chest compressions were paused. The key take home is that ETI during CPR is really hard. Be prepared.
For adults with out-of-hospital cardiac arrest, initial laryngeal tube insertion by emergency medical service providers was associated with improved 72-hour survival, return of spontaneous circulation, hospital survival, favorable neurologic outcome, and airway success compared to initial endotracheal tube insertion.
Epinephrine for out-of-hospital cardiac arrest improved overall 30-day survival (3.2%, epi vs 2.4%, placebo) but did not improve survival to discharge with a good neurological outcome. In fact, more patients who received epinephrine and survived had severe neurological impairment than in the placebo group.
