Ultrasound Guided Erector Spinae Plane Block Versus Quadratus Lumborum Block for Postoperative Analgesia in Patients Undergoing Laparoscopic Sleeve Gastrectomy

A Randomized Controlled Trial for Postoperative Analgesia in Patients Undergoing Laparoscopic Sleeve Gastrectomy: Ultrasound Guided Erector Spinae Plane Block Versus Quadratus Lumborum Block

Postoperative pain control is a significant challenge in medical practice. Inadequate pain control could decrease patient's satisfaction, delay postoperative ambulation, increase the incidence of pulmonary and cardiac complications and cause the development of chronic postoperative pain. Laparoscopic surgical techniques could decrease postoperative pain and opioid consumption.

The addition of regional techniques to general anesthesia showed better pain management and less consumption of opioids compared to the traditional techniques.

The aim of this study is to compare the effectiveness of ultrasound guided erector spinae plane block versus quadratus lumborum block regarding postoperative analgesia in patients undergoing laparoscopic sleeve gastrectomy.

Inclusion Criteria:

• Patients with free medical history or controlled hypertension and/ or diabetes scheduled for elective laparoscopic sleeve gastrectomy.

Exclusion Criteria:

• Patients unfit for surgery or refuse to sign the consent of regional block.
• Patients with known coagulation defects.
• Patients with known hypersensitivity to bupivacaine.
• Patients with infection at the site of injection.
• Conversion of laparoscopic surgery to laparotomy
