The Postoperative Lidocaine and Ketamine Effects on Morphine Requirement in Bariatric Surgery

About This Study

The goal of this observational study is to evaluate the quality of postoperative analgesia in a group of obese patients schedule to bariatric surgery under TIVA Opiod-free after to receive lidocaine and ketamine perfusion. The main question it aims to answer are: How lidocaine and ketamine perfusion during recovery period does impact over morphine consumption on the following 48 hours after surgery? All participants will receive total intravenous anesthesia and, at the end of the surgery, they will be divided in two groups, group A: placebo and, group B: with postoperative lidocaine and ketamine perfusion. Our hypothesis is ketamine and lidocaine are a good alternative to decrease the use of morphine in obese patients.
