Clinical value and influencing factors of intraoperative monitoring of jugular venous oxygen saturation

Abstract

Intraoperative jugular venous oxygen saturation (SjvO₂) monitoring has been widely used in clinic, which can monitor cerebral blood flow (CBF) and oxygen metabolism. Reverse puncture and catheterization through jugular vein for monitoring SjvO₂ is easy to operate and can collect blood samples repeatedly. It is an effective method for real-time dynamic evaluation of cerebral oxygen supply-demand and neurological function. This article reviews the clinical significance and influencing factors of SjvO₂ monitoring during operation. It notes in particular that SjvO₂ can not be used as the only way to monitor CBF and oxygen metabolism, and a comprehensive evaluation should be done combining with the change of other parameters.
