Focussing cellular function. Metabolic monitoring in perioperative and Intensive Care Medicine

In the clinical field microdialysis today is a routine technique for monitoring the chemistry of tissues and organs in physiological and pharmacological research on animals. In more than 10.000 papers on microdialysis research it is used to uncover physiological mechanisms and the influence of drugs in almost every organ of the body. Since the first papers describing microdialysis in the human brain microdialysis has become a technique for routine monitoring of energy metabolism especially in neurointensive care. This paper gives an account of the microdialysis technique describing its practical use and interpretation in monitoring energy metabolism and ischemia in different organs with respect to the field of perioperative and intensive care medicine. This article gives an overview over current results of clinical studies using microdialysis in critical care medicine and tries to focus on possible indications for clinical biochemical monitoring. However, despite numerous publications available microdialysis has not been shown to improve outcome of the patients yet.
