ABSTRACT
Determine the influence of low-pressure pneumoperitoneum on intraope-rative heamodynamic effects and postoperative shoulder-tip pain [STP] in patients undergoing diagnostic and minor gynecologic laparoscopie procedures. Prospective randomized study conducted in the endoscopic unites at Zagazig and Benha university hospitals. The study comprised 80 women undergoing diagnostic and minor laparoscopic procedures where pneumoperitoneum with high Co2 pressure [13-15 mHg] used in 40 women [group A] and with low Co2 pressure [7-10 mNg] in another 40 women [group B]. There was significant increase in the mean arterial pressure [MAP] in both groups at [5 mm.] after insufflation and tilting the patient to Trendelenberg position but there was significant decrease of [MAP] in [group B] as compared to [group A] [P< 0.05]. Both the frequency and intensity of postoperative shoulder-tip pain were lower in [group B] than in [group A], [[20%], [5.1]] versus [[35%], [7.4]] and the differences were statistically significant, especially at [6, 12, 24, 48] hours postoperatively. There was significant reduction of the mean amount consumed analgesic [declophenac potassium] in [group B] compared to [group A] [75 mg] versus [131.25 mg]. Low-pressure pneumoperitoneum used in diagnostic and minor gynecologic laparoscopic procedures allows more stable intraoperative hemodynamics of the patients and reduction of both frequency and intensity of postoperative shoulder-tip pain, with reduction of postoperative analgesics used
