Gastric reactance as a marker for major perioperative complications in high-risk cardiac surgery patients undergoing cardiopulmonary bypass.

ABSTRACT:

Background

Gastric reactance (XL) is a bioelectrical property of the stomach lining that responds to changes in gut perfusion. It is measured through bioimpedance spectroscopy, a technology that assesses the tissue's electrical resistance and capacity to store electrical charge, providing insight into the physiological state of the gastric mucosa.

Objective

This prospective observational study explored the relationship between XL and hemodynamic variables in high-risk adult patients undergoing elective cardiac surgery with cardiopulmonary bypass (CPB) at the National Institute of Cardiology, Mexico City.

Methods

A binary composite endpoint was constructed to aggregate major perioperative complications into a single outcome measure. The sample size was calculated based
