Neuromuscular Blockade and Surgical Conditions

Summary

The aim of the present study is to prospectively assess whether deep neuromuscular blockade (NMB) (zero response to train of four and a post tetanic count of no more than 10 responses using a nerve stimulator monitoring) until the end of surgery, followed by sugammadex (bridion®) reversal is superior to the present practice of gradual NMB reduction at the end of surgery followed by neostigmine (Prostigmin®, Vagostigmin®) reversal, in patients undergoing laparoscopic sleeve gastrectomy. The investigators hypothesize that providing deep NMB throughout the procedure creates better conditions for surgery, while reversal of deep NMBwith sugammadex (bridion®) will enable quick and full reversal of relaxation and fewer postoperative respiratory events as compared to neostigmine (Prostigmin®, Vagostigmin®)reversal. Participants will be followed for the duration of hospital stay, an expected average of 7 days.
