Effect Low Pressure Pneumoperitoneum and Pulmonary Recruitment on Postoperative Pain

The Effect of Low Pressure Pneumoperitoneum and Pulmonary Recruitment Manoeuvre on Postoperative Pain After Laparoscopic Cholecystectomy

The investigators want to test the hypothesis that the addition of a recruitment manoeuvre to a low pressure pneumoperitoneum will lead to an additional reduction in postoperative pain. Therefore the investigators will conduct a prospective randomized controlled, single blind trial.

Two groups:

1. A cholecystectomy at a low pressure pneumoperitoneum (8-10 mmHg)
2. A cholecystectomy at a lowpressure pneumoperitoneum (8-10mmhg) and at the end a pulmonary recruitment manoeuvre (5 sec at max 40 cmH2O).

Inclusion Criteria:

• ASA I and II

Exclusion Criteria:

• refusal to give consent
• cholecystitis
• BMI above 35
• intolerance to one of the pain medication
• pregnancy
