The incidence of residual neuromuscular blockade associated with single dose of intermediate-acting neuromuscular blocking drugs.

Background: The goal of this study is to investigate the incidence and risk factors of residual paralysis associated with single-dose intermediate-acting muscle relaxants (atracurium, vecuronium, rocuronium) during early postoperative period.

Methods: Adult patients (ASA I and II) who received a single dose of vecuronium, atracurium or rocuronium during general anesthesia for elective surgical procedure were included in the study. Train-of-four (TOF) ratios under 0.
