Maneuvers to decrease laparoscopy-induced shoulder and upper abdominal pain: a randomized controlled study.

OBJECTIVE: To evaluate the effectiveness of the pulmonary recruitment maneuver (PRM) and intraperitoneal normal saline infusion (INSI) in removing postlaparoscopic carbon dioxide from the abdominal cavity to decrease laparoscopy-induced abdominal or shoulder pain after surgery.

DESIGN, SETTING, AND PATIENTS: A prospective, randomized, controlled trial was conducted at Taipei Veterans General Hospital, Taipei, Taiwan, from August 1, 2009, through June 30, 2010. One hundred fifty-eight women undergoing laparoscopic surgery for benign gynecologic lesions were randomly assigned to 3 groups: the PRM group (n = 53), the INSI group (n = 54), and the control group (n = 51).

INTERVENTIONS: Postoperative maneuvers included PRM and INSI.

MAIN OUTCOME MEASURES: Evaluation of pain, including abdominal pain and shoulder pain, was performed at 12, 24, and 48 hours postoperatively.

RESULTS: The frequency of postoperative shoulder pain at 24 and 48 hours was significantly decreased in the INSI group compared with that of either the PRM or control group (40.7% and 24.1% in the INSI group vs 66.0% and 50.9% in the PRM group [P = .009 and .004, respectively] or vs 72.5% and 54.9% in the control group [both P < .001]). Both methods significantly reduced the frequency of upper abdominal pain compared with the control condition (73.6% in the PRM group at 24 hours [P = .03] or 72.2% at 24 hours [P .02] and 44.4% at 48 hours [P = .01] in the INSI group vs 90.2% at 24 hours and 68.6% at 48 hours in the control group).

CONCLUSIONS: Both PRM and INSI could effectively reduce pain after laparoscopic surgery, but INSI might be better for both upper abdominal and shoulder pain.
