The neuromuscular blocking action of vecuronium in normal patients and in patients with no renal function and interaction vecuronium-tobramycin in renal transplant patients.

The new short acting steroid muscle relaxant vecuronium was tested clinically in 42 surgical patients and compared in three different groups of patients: normal patients, renal graft patients who received tobramycin preoperatively and other anephric patients undergoing surgery. Twenty-five percent recovery of initial twitch height as measured by NTM was significantly longer in the renal graft group than in the two other groups where recovery time is normal. Cardiovascular parameters were recorded before and after the injection of vecuronium. Reversal of the neuromuscular block was spontaneous or pharmacologically evoked by neostigmine. Clinical recovery was complete in all patients and there was no residual block.
