Acceleromyography Versus Electromyography for Neuromuscular Recovery Assessment at the End of Surgery

This prospective observational study aims to evaluate the agreement between acceleromyography and electromyography for measuring train-of-four (TOF) ratio at the end of surgery before reversal of neuromuscular blockade. Adult patients undergoing elective laparoscopic cholecystectomy under general anesthesia with non-depolarizing neuromuscular blockade will undergo simultaneous TOF measurements using both monitoring methods. The study will assess the agreement between the two techniques, estimate measurement bias and limits of agreement, and determine the frequency of clinically relevant disagreement that could affect assessment of neuromuscular recovery and safe extubation.
