Background:Although abdominal laparoscopic surgery is known for less pain compared with that of laparotomy, many patients still complain considerable post-operative pain. Pneumoperitoneum affects several homeostatic systems leading to alteration in cardiovascular, pulmonary physiology and stress response. The benefits of an adequate analgesia include a reduction in stress response of surgery, reduction in perioperative morbidity and effective pain control can also facilitate rehabilitation and accelerates recovery from surgery.
