Brief Summary

Following laparoscopic bariatric surgery, multimodal analgesia is recommended to avoid the adverse effects of opioids by reducing their use. Although lidocaine, ketamine, and dexmedetomidine have been used as adjuvant analgesics, no studies have evaluated the superiority of their intra- and postoperative infusions as components of multimodal analgesia in bariatric surgery. The present study is aimed to compare lidocaine, dexmedetomidine, and ketamine in multimodal analgesia management following Sleeve Gastrectomy Surgery. Postoperative pain scores, the requirement for additional postoperative analgesia, retching, nausea and vomiting, time to mobilization, and hospital length of stay will be evaluated.

Outcome Measures

Primary Outcomes (1)

  • Postoperative pain: VAS scores at rest and movement

    Pain status at rest and movement will be assessed by VAS scores. The Visual Analog Scale (VAS) is a 10 cm line with anchor statements on the left (no pain) and on the right (worst pain imaginable).

    Up to 15 days after the surgery.

Secondary Outcomes (4)

  • Postoperative Rescue Analgesic Requirement

    Up to three days after surgery

  • Postoperative nausea, retching and vomiting

    Up to 3 days after surgery.

  • Time to first mobilization

    Up to 24 hours after surgery.

  • Time to discharge

    Trough hospital stay, an average of 1 week.

Study Arms (3)

Group L

ACTIVE COMPARATOR

IV lidocaine infusion (1-2 mg/kg/h) up to postoperative 12 hours.

Drug: Lidocain

Group K

ACTIVE COMPARATOR

IV ketamine infusion (0.3-0.5 mg/kg/h) up to postoperative 12 hours.

Drug: Ketamine

Group D

ACTIVE COMPARATOR

IV dexmedetomidine infusion (0.3-0.5 mg/kg/h) up to postoperative 12 hours.

Drug: Dexmedetomidine

Interventions

IV lidocaine infusion (2 mg/kg/h) will be initiated after anesthesia induction and decrease the dosage to 1 mg/kg/h at the end of surgery. The infusion will continue until 12 hours after the operation.1 g paracetamol, 100 mg tramadol, 100 mg ketoprofen, and 4 mg dexamethasone will be administered to all patients pre-emptively. Granisetron (3 mg) will be administered 30 minutes before the end of surgery. In the postoperative period, i.v. Paracetamol will be administered at 8-hour intervals and 25-50 mg meperidine i.m. (maximum dose 200 mg) as rescue analgesia when requested by the patient and if VAS\>4.

Group L

IV ketamine infusion (0.5 mg/kg/h) will be initiated after anesthesia induction and decrease the dosage to 0.3 mg/kg/h at the end of surgery. The infusion will continue until 12 hours after the operation.1 g paracetamol, 100 mg tramadol, 100 mg ketoprofen, and 4 mg dexamethasone will be administered to all patients pre-emptively. Granisetron (3 mg) will be administered 30 minutes before the end of surgery. In the postoperative period, i.v. Paracetamol will be administered at 8-hour intervals and 25-50 mg meperidine i.m. (maximum dose 200 mg) as rescue analgesia when requested by the patient and if VAS\>4.

Group K

IV dexmedetomidine infusion (0.5 mg/kg/h) will be initiated after anesthesia induction and decrease the dosage to 0.3 mg/kg/h at the end of surgery. The infusion will continue until 12 hours after the operation.1 g paracetamol, 100 mg tramadol, 100 mg ketoprofen, and 4 mg dexamethasone will be administered to all patients pre-emptively. Granisetron (3 mg) will be administered 30 minutes before the end of surgery. In the postoperative period, i.v. Paracetamol will be administered at 8-hour intervals and 25-50 mg meperidine i.m. (maximum dose 200 mg) as rescue analgesia when requested by the patient and if VAS\>4.
