Hemodynamic and oxygen transport responses in survivors and nonsurvivors of high-risk surgery

Abstract

The data indicate that there are increased metabolic requirements after surgical trauma and that the changes in cardiac index and DO2 represent compensatory increases in circulatory functions stimulated by increased metabolic needs. However, these metabolic needs change with age, gender, severity of illness, type of operation, associated medical conditions, duration of shock, complications, organ failure, and outcome.
