Comparison of an Opioid-Free Anesthesia Protocol Versus Standard Practices on Early and Late Post-operative Recovery

Opioid-Free Anesthesia (OFA) is an anesthesia protocol that does not use morphine, and is increasingly used routinely. Indeed, this protocol would theoretically allow a better post-operative analgesic control, a lower incidence of post-operative complications (e.g. post-operative nausea and vomiting). In the end, it would also allow a better overall post-operative recovery and a decrease in the incidence of chronic post-operative pain. Nevertheless, the literature is poor on this issue and no randomized controlled study has evaluated the effect of the use of this type of anesthesia protocol on postoperative recovery.
