Effect of Intraoperative Anesthetic Management on Postoperative Nausea and Vomiting in Bariatric Surgery

February 19, 2016 updated by: Patrick Ziemann-Gimmel, Coastal Anesthesiology Consultants

Effect of Intraoperative Anesthetic Management on Postoperative Nausea and Vomiting (PONV) in Bariatric Surgery

Morbidly obese patients are at high risk for Postoperative Nausea and Vomiting (PONV) after surgery and general anesthesia. The results of our observational study indicate that 42.7% of patients require medication to treat PONV in the first 24 hours after bariatric surgery despite our aggressive perioperative approach with triple prophylaxis. Common risk factors for PONV are the use of intraoperative narcotics and anesthetic gases.

Preliminary results of multimodal postoperative analgesia in the first 24 hours lead to a reduction of narcotic consumption, desaturations and use of antiemetic medication.

Our study hypothesis is that different types of anesthetics reduce PONV further.

Patient would be randomly assigned to receive either our current intraoperative management or a narcotic free, total intravenous general anesthetic (TIVA).

The investigators hope to improve patients' satisfaction by reducing PONV in the postoperative period.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
No Intervention: Balanced Anesthesia
Patients will receive balanced general anesthesia including volatile anesthetics and narcotics. This reflects our current clinical practice.
Active Comparator: NoNarc TIVA
Patients will receive narcotic free total intravenous anesthesia with Propofol, dexmedetomidine and ketamine
Drug: TIVA NoNarc
  • patients in both groups receive antiemetic prophylaxis
  • patients in the TIVA NoNarc group will receive propofol, dexmedetomidine, ketamine, ketorolac and acetaminophen intraoperatively
  • postop management in both groups is similar in both groups
