RESUMEN
BACKGROUND: To aware of postoperative residual neuromuscular block (PRNB) is important in that it can cause apnea, delay of awakening and recovery and dissatisfaction of patient.This study aimed to evaluate the PRNB at recovery room and it's course during postoperative periods. METHODS: A questionnaire designed to provide information concerning PRNB, monitoring and reversal on neuromuscular block was sent to all members of the Korean Society of Anesthesiologists by e-mail.The contents of survey were about the incidence of PRNB, the monitoring methods of the muscle relaxation.We also investigated the usual type of neuromuscular blocker and reversal agents. RESULTS: Most responders (85.9%) concerned about the PRNB of which causing a serious problem.More people answered that clinical evaluation was more reliable (83.3%) than tetanic stimulation (46.2%) and neuromuscular monitoring might reduce PRNB. Some responders (11.5%) sometimes omitted the reversal of neuromuscular block.Quantitative neuromuscular monitoring devices were not enough to use in all patients at all hospitals. CONCLUSIONS: The responders had great interest to PRNB but neuromuscular monitoring and reversal of neuromuscular blockade were underused.
