Background It remains unknown whether the administration of a deep neuromuscular block (NMB) during bariatric surgery improves surgical conditions and patient outcome. The authors studied effect versus moderate NMB in laparoscopic on postoperative pain. Methods Results One hundred patients scheduled to undergo elective were randomized (post-tetanic-count 2–3) or (train-of-four 1–2). quality field was scored using Leiden-Surgical Rating Scale (L-SRS), 5-point scale ranging from 1 (extremely poor conditions) 5 (optimal conditions). Three surgeons L-SRS at 10-min intervals surgery; pain scores obtained postanesthesia-care-unit (PACU) ward. Mean (95% confidence interval) 4.2 (4.0–4.4) 4.8 (4.7–4.9) (p < 0.001). Moderate resulted 17% 1–3, while 100% high end (4–5). Deep led improved PACU (4.6 (4.2–4.9) 3.9 (3.6–4.4), p = 0.03) reduced shoulder ward (1.8 (1.5–2.1) 1.3 (1.1–1.5), 0.03). A composite score opioid use favoured Conclusions In surgery, relaxation has advantages for surgeon patient. Compared NMB, produced stable with less
