AirSeal®Insufflation Trocar/CO2 Absorption Study

Gynecologic Diseases Clinical Trial

Official title: A Comparison of CO2 Absorption During Gynecologic Laparoscopy Using the AirSeal® Valveless Trocar System Versus Standard Insufflation Trocars at Intra-abdominal Pressures of 10 mmHg and 15 mmHg - a Randomized Controlled Trial

Status Completed

Clinical Trial Summary

The purpose of this study is to compare carbon dioxide (CO2) absorption during gynecologic laparoscopy using the AirSeal® valveless trocar system versus standard insufflation trocars at intra-abdominal pressures of 10 and 15 mmHg.

The investigators hypothesize that with the AirSeal® valveless trocar system, gynecologic laparoscopy can be performed at a lower intra-abdominal pressure with a possible resultant decrease in CO2 absorption, while maintaining adequate visualization of the operative field for safe completion of surgery.

Clinical Trial Description

Three main factors affect patients' cardiopulmonary status during gynecologic laparoscopy: 1) degree of Trendelenburg tilt (25 - 30°), 2) carbon dioxide (CO2) absorption and 3) increased intra-abdominal pressure (10 -20 mmHg). Slight modifications to any or all of these three factors can lead to a significant decrease in morbidity.

The AirSeal® valveless trocar system reduces CO2 absorption when compared to standard trocars during renal laparoscopy. Also, use of this trocar system provides a more stable intra-abdominal pressure when compared to standard trocars, a feature that could possibly allow for laparoscopic surgery to be performed at lower intra-abdominal pressures. ;
