Bupivacaine With Epinephrine Over Diaphragm in Laparoscopy

Cedars-Sinai Medical Center

Start Date

3/2/2026

Completion Date

1/1/2027

Summary

Postoperative shoulder pain is often reported to be particularly bothersome after laparoscopy. The benefits of local anesthetic, such as bupivacaine, applied to subcutaneous tissue for general postoperative pain management after surgery is well established. However, there have been no studies on sprayed bupivacaine over the diaphragm to reduce shoulder pain in laparoscopic surgery. The purpose of the study is to evaluate if sprayed infra-diaphragmatic bupivacaine compared to placebo (saline) will improve postoperative shoulder pain in patients undergoing benign laparoscopic gynecologic surgery. The entire study will be conducted at Cedar Sinai Medical Center.
