When managing the airway of a morbidly obese patient in the ED, how significant is the sniffing position in terms of increasing success of endotracheal intubation?
In fact, the sniffing position results in suboptimal positioning for laryngoscopy in an obese patient (Ann of EM, epub ahead of print, 8/10 edition).
When performing an emergency adult cricothyroidotomy, what size endotracheal tube can be used as an alternative to the tracheostomy tube?
A 6-mm ETT can be used as an alternative to a tracheostomy tube, but this option is much less preferable because an ETT is more difficult to secure to the patient’s neck.(NEJM, Vol. 358:e25).
At doses typically used for rapid sequence intubation, succinylcholine causes motor paralysis that lasts for how long? What about rocuronium?
Rocuronium causes motor paralysis for about 45 minutes, much longer than the 6-10 minutes for succinylcholine (JEM, Vol. 37, pg. 186).
When used for RSI, motor paralysis induced by rocuronium lasts for how long? What about succinylcholine?
Rocuronium, in a dose of 1 mg/kg, also causes motor paralysis for about 45 min, much longer than the 6–10 min for succinylcholine (JEM, Vol. 37, pg. 183).
