Could a simple Head-Down tilt reduce Post-Surgery shoulder pain?
NCT ID NCT07631728
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This trial tests whether tilting patients head-down (Trendelenburg position) during removal of surgical gas after laparoscopic surgery reduces shoulder pain and bloating compared to lying flat. 120 adults undergoing robot-assisted laparoscopic gynecologic surgery will be randomly assigned to one of two positions during gas removal. Participants will report pain and other symptoms 24 and 72 hours after surgery.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Trendelenburg positioning (head-down tilt) and pulmonary recruitment maneuvers
- What this could lead to
- If it works, this simple positioning change could reduce shoulder pain and bloating after laparoscopic surgery, making recovery more comfortable.
- What could go wrong
- This is a small, early-stage trial testing a temporary positioning change, so results may not apply to all surgeries or patients. The effect on pain may be modest.
