[Atracurium, vecuronium and pancuronium. Results of a polygraphic study].
The Authors have studied three nondepolarizing muscle relaxants widely used: pancuronium v/s atracurium and vecuronium. The Train of Four was used to detect the magnitude of the neuromuscular blockade. The intubation follows 90 minutes after administration of the drugs and for each patient the Authors valued: 1) the T1 and TR values at intubation; 2) the onset-time; 3) the duration of neuromuscular blockade; 4) the recovery time. Furthermore, the degree of neuromuscular blockade was clinically checked both at the time of induction and at recovery. The results of the present study show, in accordance with the literature, that all three drugs tested are capable of obtaining complete muscle relaxation. Atracurium and vecuronium particularly allow an adequate intubation at the adopted doses (0.6 mg/kg and 0.1 mg/kg respectively) with a relatively short onset-time (medium values 136" in the group of atracurium and 146" in the group of vecuronium) and a restoration time faster than pancuronium.
