Brief Summary: Anaesthesia has three major components, analgesia, muscle relaxation and hypnosis.

For a long time, opioids have been covering the analgesia function. (1) When using opioids, an analgesic effect is obtained per-operatively, however, not without side-effects. Post-operative complications such as: respiratory depression, post-operative nausea and vomiting, pruritus, acute opioid tolerance and hyperalgesia, difficulty voiding and ileus, are well known.

Opioid usage is an important risk factor of postoperative desaturation. Postoperative desaturation can lead to severe hypoxemia and even tissue hypoxia, followed by obvious cardiologic and neurological complications.

Thus, in patients at risk, such as the obese patient, experts suggest reducing opioid usage.

Non-opiate protocols implemented on the obese patient have been published. Non-opiate protocols have been established using a combination of ketamine, lidocaine and an alpha-2 agonist.

The main purpose of this pilot study is to evaluate whether patients undergoing an opioid free anaesthesia regime experience less desaturation episodes during the first 24 h post-bariatric surgery than patients having received an opioid anaesthesia regime.
