Metabolic and immunologic consequences of laparoscopy with helium or carbon dioxide insufflation: A randomized clinical study

Abstract

The choice of insufflation gas can affect intraperitoneal macrophage function in the clinical setting, and possibly acid-base balance. The present study suggested no immunological advantages for the clinical use of helium as an insufflation gas. The outcomes of the present study, however, are different to those obtained from previous laboratory studies and further research is needed to confirm this outcome.
