Magnesium Sulfate Reduced Opioid Consumption in Obese Patients Undergoing Sleeve Gastrectomy: a Prospective, Randomized Clinical Trial.

OBJECTIVE

The purpose of the study was to investigate the effect of magnesium sulfate on pain management for pain after sleeve gastrectomy operation.

DESIGN

A prospective, randomized, placebo-controlled clinical study.

SETTING

University hospital.

PARTICIPANTS

Eighty patients undergoing sleeve gastrectomy.

MEASUREMENTS AND MAIN RESULTS

Visual analog scale for the evaluation of pain, sedation score, mean arterial pressure, heart rate, and total analgesic consumption was recorded. Serum magnesium levels were determined before the operation, at the end of the operation, and at 24 h. There were no significant differences between the groups with respect to demographics, and sedation scores. Cumulative morphine consumption and pain scores were found to be higher in the control group than the magnesium group.

CONCLUSION

Perioperative use of magnesium sulfate reduced postoperative pain and opioid consumption in obese patients undergoing sleeve gastrectomy operations.
