About this trial

This proposed study is a single-center, double blind, parallel group RCT comparing the use of low (10 mm Hg) versus standard pressure (15 mm Hg) pneumoperitoneum at the time of benign gynecologic laparoscopic surgery. Patients will be randomized to the control group (standard pressure) or the intervention group (low pressure) and surgeons will be blinded to the study pressure. Data on post-operative recovery and pain scores will be recorded for each patient.

Trial outcomes

Primary outcomes

1

Shoulder Tip Pain

The primary endpoint is post-operative shoulder tip pain measured on post-op day 1 following surgery by a self-administered NRS (numeric rating score) for pain, on a scale from 0 (no pain) to 10 (worst pain imaginable).

Time frame
Post-op day 1

Secondary outcomes

1

Shoulder Tip Pain (Short-term)

NRS (numeric rating score) scores for shoulder-tip pain at 1 and 2 hours on a scale from 0 (no pain) to 10 (worst pain imaginable)

Time frame
1 and 2 hours after surgery
2

Quality of Recovery (QoR) score

QoR (Quality of Recovery) score on post-op day 1: a pre-validated score out of 150 (higher score corresponds to better recovery)

Time frame
Post-op day 1
3

Generalized Pain Score

Generalized pain at 1 and 2 hours and on post-op day 1. Self-reported NRS pain score on a scale 0-10.

Time frame
1, 2 hours post-op and post-op day 1
4

Incidence of Nausea and Vomitting

Documented incidence (yes or no) of nausea, vomiting, and bloating at 1 and 2 hours and on post-op day 1. Incidence/presence of nausea and vomiting is worse.

Time frame
1, 2 hours post-op and post-op day 1
