Patients >18 years of age with an america society of anesthesiologist classification of I or II who are scheduled to undergo elective robot assisted laparoscopic radical prostatectomy are included. The exclusion criteria are a history of neuromuscular, renal, or hepatic disease, known allergy to rocuronium or sugammadex. Patients are randomized to either the moderate or deep neuromuscular blockade group using Random Allocation Software (version 1.0). In the operating room, routine monitoring is performed, including electrocardiography, non-invasive arterial pressure measurements, and pulse oximetry. Additionally, acceleromyography are applied to monitor the response of the adductor pollicis muscle. After the induction of anesthesia with propofol and before rocuronium administration, the TOF-Watch-SX is calibrated and stabilised, and a series of train-of-four (TOF) measurements are documented every 1 min. Next, intravenous rocuronium at 0.6 mg/kg was administered, and tracheal intubation was performed after confirmation of relaxation. Anesthesia is maintained with desflurane and target-controlled infusion of remifentanil while monitoring the bispectral index. Intravenous rocuronium (5-10 mg) is used to maintain moderate (TOF count of 1 or 2) or deep (post-tetanic count [PTC] of 1 or 2) neuromuscular blockade. Peak inspiratory pressure and plateau pressure are recorded until 1 hour after pneumoperitoneum. At the end of the operation, the surgeon rated the surgical condition on a 5-point scale. Patients are reversed with intravenous sugammadex at 2 or 4 mg/kg. Postoperative pulmonary complications (SpO2 <100%, RR<8, atelectasis) are assessed and recorded.
