Study summary

Laparoscopic surgery has become a standard of care for many gynecological surgeries due to its lower morbidity, pain and cost compared to open techniques. Unfortunately, the use of carbon dioxide (CO2) to insufflate the abdomen is a major contributor to post operative shoulder pain. Shoulder pain post laparoscopy is common and it is a major cause of patient dissatisfaction. The aim of our study is to evaluate the efficacy of positioning the patient in Trendelenburg, post operatively for 24 hours, on shoulder pain reduction. Our hypothesis is based on the assumption that complete CO2 deflation is not possible and that Trendelenburg positioning will help displace CO2 from the sub diaphragmatic area thus reducing the diaphragmatic and phrenic nerve irritation causing pain.

Read the detailed description

A prospective randomized controlled study with 54 patients in each of the two arms. Group S (control) will undergo the standard laparoscopic procedure and the patients will be placed in supine head up position postoperatively. In group T (interventional); the patients will be positioned in Trendelenburg position once fully awake and cooperative in the post-anesthesia case unit (PACU) and will remain in this position for the first 24 hours postoperatively. Postoperative NRS(numeric rating scale) score for shoulder pain and nausea will be collected at arrival to PACU, \& 4, 6, 12 and 24 hours postoperatively. In addition, total amount of rescue pain and nausea medication used by the patient will be recorded. Data collected will be analyzed and compared between the two groups. The independent t- test will be used to compare postoperative shoulder pain, with NRS scores treated as continuous variable, between the two groups.

Study arms

  • No intervention
    Group S

    Control group (Group S: 54 patients); this group will undergo the standard laparoscopic procedure (the procedure is done in Trendelenburg position). While in Trendelenburg position and prior to wound closure and with laparoscopic port valves open, the patient's abdomen will be passively deflated. The patients will be placed in supine head up position in the post anesthesia care unit (PACU).

  • Experimental
    Group T

    Intervention group (Group T: 54 patients); the patients will be subject to the same maneuver as in arm 1 prior to wound closure but will be positioned in a 20 degree Trendelenburg position once fully awake and cooperative in the PACU and will remain in this position for the first 24 hours post operatively, even after they are transferred to their rooms on the American University of Beirut Medical Center (AUBMC) floors. The maximum time allowed in a straight-up position will be three 15-minute intervals over a 24-hour period (the first interval being a clear fluids intake at 12 hours postoperatively).

    Procedure: 20 degree Trendelenburg position

Interventions

  • Procedure20 degree Trendelenburg position

    The patients in the intervention group will be placed in trendelenburg position postoperatively.
