Study of Carbon Dioxide Exchange Patterns During Robotic Prostatectomies

A Comparative Study of CO2 Exchange Patterns Between Valve-free Trocar (AirSeal®) Versus Standard Trocar (Endopath®) During Robotic Prostatectomies

The AirSeal® System will allow for lower carbon dioxide (CO2) absorption rates than the standard Endopath System.

The primary observation to be made is the level of carbon dioxide in the arterial blood, specifically when the patient is insufflated and deflated during the surgery. As a result of the consistent pressure that the AirSeal® system maintains, carbon dioxide will be absorbed in lower levels when compared to the standard of care systems in which fluctuations in intra-peritoneum pressure are seen.
