Visual Evaluation of Residual Curarization in Anesthetized Patients Using One Hundred-Hertz, Five-Second Tetanic Stimulation at the Adductor Pollicis Muscle

Abstract

After the administration of muscle relaxants, the absence of visual fading at the adductor pollicis, elicited in anesthetized patients by 100-Hz, 5-s tetanus, is compatible with a train-of four ratio > 0.85. Therefore, clinical observation of fading after 100-Hz, 5-s tetanus seems to be a highly sensitive test in evaluating residual paralysis.
