Postoperative reductions in (A) PEF and (B) FVC values as the percentage of preoperative values in patients with (RNMB-present) and without (RNMB-absent) RNMB among patients receiving vecuronium, atracurium, and rocuronium. Within the groups, only the FVC reduction in RNMB-present patients receiving vecuronium was significantly lower compared with RNMB-absent patients. *P < 0.001 compared with the corresponding RNMB-absent patients. Across the groups, the postoperative PEF and FVC reductions among RNMB-absent patients receiving the three NMB agents were similar, and the difference in postoperative PEF and FVC reductions among RNMB-present patients receiving the three NMB agents was not statistically significant. PEF = peak expiratory flow; FVC = forced vital capacity; RNMB = residual neuromuscular blockade.
