TLDR
Near‐infrared spectroscopy provides noninvasive continuous access to the venous side of regional circulations that can approximate organ‐specific and global measures to facilitate the detection of circulatory abnormalities and drive goal‐directed interventions to reduce end‐organ ischemic injury.Abstract:
The safety of anesthesia has improved greatly in the past three decades. Standard perioperative monitoring, including pulse oximetry, has practically eliminated unrecognized arterial hypoxia as a cause for perioperative injury. However, most anesthesia-related cardiac arrests in children are now cardiovascular in origin, and standard monitoring is unable to detect many circulatory abnormalities. Near-infrared spectroscopy provides noninvasive continuous access to the venous side of regional circulations that can approximate organ-specific and global measures to facilitate the detection of circulatory abnormalities and drive goal-directed interventions to reduce end-organ ischemic injury.read more

TL;DR: Test the hypothesis that near-infrared spectroscopy (NIRS)-derived cerebral and somatic/renal regional saturations can predict survival by analyzing relationships between standard hemodynamic measures, direct and NIRS measures of saturation, and outcome.

Cerebral Oxygenation During Pediatric Cardiac Surgery Using Deep Hypothermia Circulatory Arrest
TL;DR: Brain oxygenation changed at distinct points during surgery in all ages, reflecting fundamental cerebral responses to hypothermic CPB, ischemia, and reperfusion, consistent with experimental work in animals.

Comparing near-infrared spectroscopy devices and their sensors for monitoring regional cerebral oxygen saturation in the neonate.
TL;DR: Compared the rScO2 values obtained in (preterm) neonates with all available sensors of three frequently used NIRS devices, sometimes there were substantial differences between the absolute rSc O2 values, which may complicate clinical application.

Near-infrared spectroscopy as a hemodynamic monitor in critical illness
TL;DR: Expert opinion would suggest that special use may exist for near-infrared spectroscopy in patients with complex circulatory anatomy, with extremes of physiology, and in whom extended noninvasive monitoring is useful.

TL;DR: A critical range of SaO(2) for optimizing systemic oxygen delivery was confirmed in control patients, and was effectively eliminated by phenoxybenzamine, specifically by eliminating the systemic hypoperfusion associated with high SaO (2).

Blood transfusions increase cerebral, splanchnic, and renal oxygenation in anemic preterm infants.
TL;DR: This work used NIRS to study the effects of red blood cell transfusions in anemic preterm infants to assess if thresholds for transfusions were appropriate for recognizing a clinical condition permitting tissue oxygenation improvement.

How do pediatric anesthesiologists define intraoperative hypotension

TL;DR: A questionnaire‐based survey of pediatric anesthesiologists was designed to determine the BP ranges and thresholds used to define intraoperative hypotension (IOH), and what constitutes hypotension in pediatric anesthesia is currently unknown.
