Detailed description

Research Problem: Laprocopic sleeve gastrectomy is the most common surgical procedure performed for reducing weight in morbidly obese patients. Laparoscopic surgery is considered to be less invasive than open surgery. The treatment of pain in obese patients is a challenge. Administering opioids, can have an increasing effect of respiratory depression in patients already at risk of sleep apnea. The evidence regarding effects of pain modulator like gabapentin on postoperative pain after sleeve gastrctomy is sparse. Gabapentin has anti-hyperalgesic and postoperative opioid-sparing properties. The analgesic effect of gabapentin appears to be related to the surgical procedure undertaken, a more procedure-specific evaluation is needed for different types of surgeries.. Research Significance: This study will highlight the effectiveness of preoperative use of gabapentin for postoperative pain management in morbidly obese patients.
