All of the following statements about neuroiuuscular blockage produced by succinyl choline are true Except-: (A) No fade on train of four stimulation, (B) Fade on tetanic stimulation, (C) No post tetanic facilitation, (D) Train of four ratio > 0.4
Answer is B. Succinylcholine is the depolarising muscle relaxant.Depolarising neuromuscular blockage is characterized by no fade on train of four or tetanic stimulation, no post tetanic facilitation and a high train of four ratio is >0.7 (>0.4). Fade on tetanic stimulation or train of four is the characteristic feature of non-depolarising blockage . ref:Miller 7th/e p. 867
