NCT03469700

Brief Summary

The incidence of obesity is steadily rising. Laparoscopic sleeve gastrectomy (LSG) is an innovative approach to the surgical management of morbid obesity. We will be discussing the effect of adding paravertebral block (PVB) in addition to general anesthesia (GA) vs. GA alone for post operative pain after laparoscopic sleeve gastrectomy.

Outcome Measures

Primary Outcomes (1)

  • postoperative pain

    The primary aim is to compare the effect of paravertebral block with general anesthesia versus general anesthesia alone on postoperative pain after laparoscopic sleeve gastrectomy surgeries. Pain will be assessed using the Visual Analogue scale (VAS) with a score of 0 denoting no pain and 10 maximum possible pain.

    within 1 week postoperatively

Secondary Outcomes (1)

  • ambulation

    within 1 week postoperatively

Study Arms (2)

GA+PVB

EXPERIMENTAL

Patients will receive general anesthesia with paravertebral block

Other: general anesthesiaOther: Paravertebral block

GA+placebo PVB

ACTIVE COMPARATOR

Patients will receive general anesthesia with placebo block

Other: general anesthesiaOther: Placebo PVB

Interventions

Induction of general anesthesia will be performed followed by endotracheal intubation. General anesthesia is induced with 0.5-1 μg/kg fentanyl, 1.5-2 mg/kg propofol and 1-2 mg midazolam. Then, endotracheal intubation is facilitated by 0.15 mg/kg nimbex. Anesthesia is maintained by 1-1.5% sevoflurane, 0.5 μg/kg/h fentanyl, 0.6 mg/kg/h rocuronium, 60% nitrous oxide and 40% oxygen with Ultiva (Remifentanyl) 0.1-0.2 μg/kg/hr

GA+PVBGA+placebo PVB

Bilateral paravertebral block guided by a nerve stimulator will be performed by injecting local anesthetic mixture from levels T11 to T6. Each 20 ml of the mixture will contain: 6 ml lidocaine 2%; 6 ml lidocaine 2% with adrenaline 5 μg /ml; 5 ml bupivacaine 0.5%; 50μg fentanyl (1 ml); and 2 ml saline 0.9%

GA+PVB

Placebo bilateral paravertebral block guided by a nerve stimulator will be performed by injecting normal saline from levels T11 to T6.

GA+placebo PVB
