Advances in the application of near-infrared spectroscopy in the perioperative period of congenital heart disease / 中华实用儿科临床杂志

ABSTRACT

Near-infrared spectroscopy (NIRS) can be employed to monitor regional oxygen saturation (rSO 2), to reflect the oxygen metabolism and local effective blood perfusion of the measured site in a real-time and noninvasive manner.NIRS has been extensively used in monitoring blood perfusion of brain, kidney, gastrointestinal tract and organ function evaluation in different conditions.During the perioperative period of congenital heart disease, hemodynamic fluctuation may easily cause organ hypoperfusion, which would lead to the development of ischemia, hypoxia and internal environment disorder, thus resulting in harmful changes in tissue oxygenation status.However, there is no change in the arterial oxygen saturation (SaO 2) and mixed venous saturation (SvO 2). NIRS can be employed to sensitively monitor the changes of tissue rSO 2, so as to prevent further injury caused by tissue ischemia and hypoxia.This paper briefly describes the basic principle, limitations and new progress of NIRS in the perioperative application of CHD, in order to provide new ideas and directions for its clinical application in the perioperative period of CHD, early evaluate the patient′s condition and guide clinical work.
