The neuromuscular blocker that does not need reversal of action by neostigmine at the end of the operation is:: (A) d-Tubocurarine, (B) Doxacurium, (C) Pipecuronium, (D) Mivacurium
Answer is D. * Long acting non-depolarizing (competitive) NM blocking agents require reversal with neostigmine. * Mivacurium is the shoest acting NDMR. It does not require reversal due to its sho duration of action. * Mivacurium can be used in day care surgery.
