Abstract:
ObjectiveTo investigate the incidence of postoperative residual paralysis and respiratory function of patients undergoing neurosurgical anesthesia.Methods Three hundred andtwenty-eight patients undergoing neurosurgical anesthesia (ASA Ⅰ - Ⅱ ) were divided into vecuronium group (135 cases) and rocuronium group (193 cases) by random digits table.Anesthesia was maintained with propofol in combination with sevoflurane and intermittented intravenous infusion boluses of muscle relaxatant.Extubation of the intratracheal tube in operation room was performed under clinical criteria.The neuromuscular function were detected by acceleromyography with supramaximal train-of- four(TOF) stimulation of the ulnar nerve,and pulmonary function were measured in postanesthesia care unit(PACU).The TOF ratio and pulmonary function were compared between two groups.ResultsThe incidence of postoperative residual paralysis was 31.9％(43/135) in vecuronium group,and 14.5％(28/193) in rocuronium group.Hypoxemia and hypercapnia occurred in vecuronium group with TOF ＜ 0.9 were higher than in those with TOF ≥0.9[7.0％(3/43) vs.4.3％(4/92) and 44.2％(19/43) vs.18.5％(17/92),P ＜ 0.01 ],while in rocuronium group with TOF ＜ 0.9 were higher than in those with TOF ≥ 0.9 [ 3.6％( 1/28 ) vs.1.2％ (2/165) and 39.3％( 11/28 )vs.17.0％ (28/165),P ＜ 0.01 ].ConclusionsThere is a high incidence of postoperative residual paralysis according to the clinical criteria of recovery of neuromuscular function of patients undergoing neurosurgical anesthesia,which would impair respiratory function.
