Clinical evaluation and advancement of perioperative minimally-invasive cardiac output monitoring methods

Abstract

Background Perioperative cardiac output (CO) monitoring of critical patients is one of the objective indicators of cardiac functions. In recent years, along with the development of software, perioperative minimally-invasive cardiac output monitoring methods get more and more attractive. Objective To summarize the new progress of perioperative minimally-invasive cardiac output monitoring and objectively evaluate their role of perioperative hemodynamic monitoring. Content The basic principle of perioperative minimally-invasive cardiac output monitoring methods (FTV, PiCCO and Modelflow)were summed up.Enumerate the clinical research to compare their accuracy with invasive(Swan-Ganz) or non-invasive(TEE) cardiac output monitoring methods. Estimate the advantages and limitations of three methods. Trend Perioperative minimally -invasive cardiac output monitoring methods are simple and safe, less trauma, high accuracy and can continuously record cardiac output and related hemodynamic parameters. Perioperative minimally-invasive cardiac output monitoring reflect the state of the cardiovascular system promptly and effectively guide therapy in critical patients undergoing anesthesia. It will be more important and widely used in the future. Key words: Cardiac output; Arterial pulse wave; Thermodilution; Modelflow model
