Post Laparoscopy Shoulder Pain and Postoperative Trendelenburg Position
Post Laparoscopy Shoulder Pain and Postoperative Trendelenburg Position
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.
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.
