many (two or three) punctures (somatic pain) or due to manipulation of the intra-abdominal
organs as ovaries, uterus, omentum, and intestine (visceral pain) or shoulder and back pain
caused by retained CO2 in the peritoneal cavity with its irritation effect on the
diaphragm.Patients will be divided into two groups:
Intraperitoneal (IP) group (20 patients):They will receive 100 ml normal saline infused over
10 min immediately before the induction of anesthesia and then continuous infusion of 500 ml
normal saline intraoperatively then intraperitoneal wash of 100 ml normal saline containing
30 mg/kg MgSO4 at the end of laparoscopy.

30 mg/kg infused over 10 min immediately before the induction of anesthesia and then
