Comparison of Low Pressure and High Pressure Pneumoperitoneum in Patients Undergoing Laparoscopic Cholecystectomy-A Randomized Prospective Study

ABSTRACT

Pneumoperitoneum of 12-16mmHg is created by instillation of carbon dioxide during laparoscopic cholecystectomy .Nowadays low pressure pneumoperitoneum of 8-10 mmHg is used to decrease the side effects. In our study we have compared the two methods. Methods: Eighty patients with gallstones admitted in Government Hospital Gandhinagar (district hospital Jammu) for laparoscopic cholecystectomy were divided into two groups of forty each. Forty patients were subjected to standard pressure pneumoperitoneum during the procedure and forty patients to low pressure pneumoperitoneum. Results: Very slight difference in operating time of two groups was seen. No significant change in postoperative blood pressure and heart rate seen. Only two patients had shoulder tip pain and required more analgesics. Conclusion: High pressure pneumoperitoneum has no effect on intra operative and post operative hemodynamics but can lead to increase in post operative pain.
