Total intravenous-opioid-free anesthesia/analgesia (OFAA) for a morbid obese patient with a body mass index of 99 kg/m2 undergoing gastric bypass: a case report

This case shows that opioid-free anesthesia/analgesia can be feasible and safe. The mandatory use of anesthetic depth monitoring together with the validation of target-control infusion models for propofol in obese patients are both recommended to facilitate the more frequent use of total intravenous anesthesia-target-control infusion in this population.
