Conference paper


A system was developed for the on-line monitoring and analysis of neuromuscular blockade during anesthesia by use of a personal computer, either PC-9801 VX or NS20 of NEC, in cooperation with NEC-San- ei Company. With this system it is possible to analyze both single and tetanic contractions of the adductor pollicis muscle and to diagnose the status of neuromuscular blockade during anesthesia.
