Aim: The present study aimed to assess the incidence of residual neuromuscular blockade in a post-anaesthetic care unit. Methods: One hundred patients with physical statuses ranging from I to III, according to the American Society of Anesthesiologists (ASA), were prospectively recruited before they were scheduled to have either elective or emergency surgery from August 2023 to August 2024. Results: Male patients with RNMB had a shorter duration of anaesthesia, had higher doses of muscle relaxant, and had a shorter time gap between the final dosage of relaxant administration and arrival in the PACU. A higher percentage of individuals with residual neuromuscular blockade (RNMB) needed assistance with their airway compared to those with a train-of-four ratio (TOFR) greater than 0.9. Conclusion: The PACU has common RNMB, according to this research. Anaesthetists should quantify neuromuscular blockade and optimize reversal utilization since RNMB may predispose to postoperative problems. Anaesthetists should be aware that even with intermediate-acting neuromuscular blockade drugs, RNMB may occur after over an hour between relaxant doses.
