<prompt> The most rapidly acting nondepolarizing neuromuscular blbcking agent which can be used as an alternative to Succinylcholine for tracheal intubation is:RocuroniumPancuroniumDoxacuriumPipecuronium  <response>: Ref: KDT 6e p345 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.
