Der Anaesthesist
-
The neuromuscular blocking and circulatory effects of a recently synthesized relatively short acting nondepolarizing muscle relaxant, Duador, have been investigated in anaesthetized patients. Duador appears to be a potent muscle relaxant with intermediate duration of action. It had no cumulative effects even after as many as five maintenance doses. ⋯ The increase in heart rate was inversely proportional to the control rate. Repeat doses did not cause further elevation in frequency. Duador had no effect on mean blood pressure.
