Pneumoperitoneum Management With SurgiQuest AirSeal® at Low vs. Higher Pressure

The study is designed and powered to demonstrate superiority of the AIS at low pressure vs. at higher pressure on a single key effectiveness measure: Incidence of shoulder pain. Patients will be randomized 1:1 to either AIS with an insufflation pressure target of 9mmHg ±1mmHg or to AIS with an insufflation target pressure of 15mmHg ±1mmHg.

Secondary outcome measures include severity of shoulder pain measured using a VAS scale and medication use, length of hospital stay, aspects of anesthesia management including end tidal CO2 and the frequency of adverse events. These outcomes will be evaluated in a controlled population undergoing laparoscopic surgery.
