A pulmonary recruitment maneuver at the end of surgery reduced shoulder pain as well as nausea and vomiting after laparoscopic surgery.

Study summary:

With IRB approval and informed consent, 100 female ASA 1 and 2 outpatients who were scheduled for elective gynecologic laparoscopic surgery were randomly allocated to either the current standard (control group) or to additional efforts to remove residual CO2 at the end of surgery (intervention group; power analysis yielded 45 patients necessary per group). In the control group, CO2 was removed by passive deflation of the abdominal cavity through the holes of the trocar. In the intervention group, CO2 was removed by means of Trendelenburg position (> 30 degrees) with 5 manual pulmonary recruitment maneuvers. Postoperative shoulder pain was assessed prior to discharge and 12, 24, 36 and 48 hours later using a visual analog scale (VAS). In addition, positional characteristics of the shoulder pain and incidence of postdischarge nausea and vomiting (PDNV) were recorded 48 hours after surgery.


Inclusion Criteria: - female - age 15-65 - ASA I-II - scheduled for outpatient gynaecological procedure Exclusion Criteria: - previous laparatomy - patients requiring hospitalisation - procedure required conversion to laparatomy - 48h follow-up no feasible
