Reducing Postoperative Opioids in Patients Undergoing Laparoscopic Hiatal Hernia

OSA protocol will include boluses of dexmedetomidine and ketamine at anesthesia induction, followed by a ketamine infusion that will continue until PACU discharge. Another bolus of ketamine will be administered upon surgical incision and another dexmedetomidine bolus will be given at surgical closure to reduce the use of opioids.

The OBA group will be administered a saline infusion at the same rate of the ketamine infusion (only while in the PACU) up until PACU discharge so that surgeons, patients, and PACU nurses will be blinded. The OBA group will be administered fentanyl 100 mcg IV for anesthesia induction followed by 50 mcg IV boluses when heart rate or systolic blood pressure is 20% above baseline throughout the case.
