The effect of tubocurarine and gallamine pretreatments on suxamethonium relaxation was measured in 81 patients. The blocking effect of a constant infusion of suxamethonium (0.58 mg/sec) on the recorded thumb adduction in response to supramaximal ulnar nerve stimulation was reproducible in 18 control subjects: infusion time for 50% block was 37.7 (+/- SEM 1.02) sec. Tubocurarine 3 mg and 6 mg increased the infusion time required to produce 50% block by 33.4 and 54.8% respectively. Gallamine had a similar effect. Clinical conditions for endotracheal intubation were evaluated on a blind basis. Both drugs produced impairment of clinical conditions for intubation after suxamethonium 60 mg infusion. However, when pretreatment by tubocurarine 3 mg was followed by suxamethonium infusion at 1 mg/sec the time course of neuromuscular blockade was identical to that of the controls. There were no fasciculations with this dosage and conditions for endotracheal intubation were excellent.
