Reduction of Pain Following Laparoscopic Surgery: A Double Blind Prospective Randomized Controlled Trial

Post-operative Pain Clinical Trial

Official title:
Reduction of Pain Following Laparoscopic Surgery: A Double Blind Prospective Randomized Controlled Trial.

Clinical Trial Summary

Shoulder tip and abdominal pain following laparoscopic procedures are well recognized as causes of post-operative morbidity. This prospective, double-blind, randomized controlled trial attempts to reduce post-operative pain in patients undergoing laparoscopic surgery by implementing a simple intra-operative technique.

Patients who undergo elective laparoscopic cholecystectomy for gallbladder disease or laparoscopic inguinal hernia repair will be recruited to the trial. Patients will be randomized to either the current standard (control group) or to receive an intervention to remove residual CO2. In the intervention group the pneumo-peritoneum will be removed, at the end of the operation, by placing the patient in the Trendelenburg position and utilising a pulmonary recruitment maneuver consisting of two manual inflations to a maximum pressure of 60 cm H2O. In the control group residual pneumo-peritoneum will be evacuated at the end of the procedure by passive decompression via the open operative ports.

Clinical Trial Description

This trial recruited 76 randomly assigned patients, 37 in the intervention group and 39 in the control group. The overall post-surgery pain scores, as analysed by two-way ANOVA, were significantly lower in the intervention group (P=0.0019). On Bonferroni post-tests both 12 hour (P<0.01) and 24-hour (P<0.01) pain scores were significantly lower in the intervention group. ;
