Intraoperative measurement of the respiratory exchange ratio predicts postoperative complications after liver transplantation.

ABSTRACT:

Background

During surgery, any mismatch between oxygen delivery (DO₂) and consumption (VO₂) can promote the development of postoperative complications. The respiratory exchange ratio (RER), defined as the ratio of carbon dioxide (CO₂) production (VCO₂) to VO₂, may be a useful noninvasive tool for detecting inadequate DO₂. The primary objective of this study was to test the hypothesis that RER measured during liver transplantation may predict postoperative morbidity. Secondary objectives were to assess the ability of other variables used to assess the DO₂/VO₂ relationship, including arterial lactate, mixed venous oxygen saturation, and veno-arterial difference in the partial pressure of carbon di
