Clinical monitoring of neuromuscular function can be accomplished by either measuring the evoked mechanical or EMG response of a skeletal muscle via an accessible motor nerve. The pattern of motor nerve stimulation varies from supramaximal single repeated stimuli at a specified frequency to tetanic stimulation, posttetanic single stimuli at the pretetanic frequency, and train-of-four stimuli at 2 Hz. The response to relaxants is unpredictable in the population at large and more so in pathologic states. ⋯ The train-of-four technique of measurement has proved to be valuable not only as a reliable clinical tool to measure the response to relaxants and monitoring recovery, but also as a research tool for studies of old and new neuromuscular blocking drugs. Evoked responses and clinical criteria for adequate recovery from muscle relaxants should complement each other. The more criteria fulfilled, the better and safer the conclusion that the patient has recovered from clinical neuromuscular blockade.

A simple method for preventing obstruction of the endotracheal tube during palatal surgery.
In this paper we describe a simple method for avoiding the obstruction of the Mallinckrodt R. A. E. (Ring, Adair and Elwin) preformed endotracheal tube which we use during cleft palate surgery, palatal lengthening and pharyngoplasty in patients who have well developed lower incisor teeth.
