Post Operative Pain

Brief summary

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.

Interventions

OTHERGroup Erector Spinae Plane Block (ESPB)

Patients will receive general anesthesia initially then bilateral ESPB with a total volume of (0.3-0.4 ml/kg LBW) of bupivacaine 0.25% will be performed (not exceeding toxic dose) 150 mg

OTHERGroup Quadratus Lumborum Block (QLB)

Patients will receive general anesthesia initially then bilateral QLB with a total volume of (0.3-0.4 ml/kg LBW) of bupivacaine 0.25% will be performed not exceeding toxic dose150 mg

OTHERGroup (C) (Control group)

Where patients will be operated under general anesthesia.
