The most rapidly acting nondepolarizing neuromuscular blocking agent which can be used as an alternative to succinylcholine for tracheal intubation is:: (A) Rocuronium, (B) Pancuronium, (C) Doxacurium, (D) Pipecuronium
Answer is A. * Rocuronium is the fastest acting Non-depolarizing muscle relaxant (NDMR). It can be used for the rapid sequence endotracheal intubation in patients having contra-indications to the use of SCh. * Mivacurium is the shoest acting NDMR. * SCh is the shoest and fastest acting skeletal muscle relaxant. It is a depolarizing NM blocker.
