Near-infrared spectroscopy: An important tool during the blalock-taussig shunt

Annals of Cardiac Anaesthesia, 2020
Near infra red spectroscopy (NIRS) is a noninvasive diagnostic tool for measuring regional oxygen saturation (rSO2). Cerebral oxygenation measured with NIRS is used to corroborate mixed venous oxygenation and hence considered an indicator of tissue ...

Findings From Somatic and Cerebral Near-Infrared Spectroscopy and Echocardiographic Monitoring During Ductus Arteriosus Ligation: Description of Two Cases and Review of Literature

Frontiers in Pediatrics, 2020
Background: Preterm infants with hemodynamically significant patent ductus arteriosus (HsPDA) are exposed to low cerebral tissue oxygen saturation (rScO2) values.

Impact of acute partial-body cryostimulation on cognitive performance, cerebral oxygenation, and cardiac autonomic activity

Scientific Reports, 2021
We assessed the effects of a 3-min partial-body cryostimulation (PBC) exposure—where the whole body is exposed to extreme cold, except the head—on cognitive inhibition performance and the possible implications of parasympathetic cardiac control and ...

Dynamics of cortical oxygenation during immediate adaptation to extrauterine life

Scientific Reports, 2021
The neonatal transition involves physiological modifications as a consequence of the complexity of the perinatal period. Various strategies can be used to attain the same level of postnatal cerebral oxygenation, depending on the status of the infant at ...

Effects of Cardiorespiratory Fitness on Cerebral Oxygenation in Healthy Adults: A Systematic Review

Frontiers in Physiology, 2022
IntroductionExercise is known to improve cognitive functioning and the cardiorespiratory hypothesis suggests that this is due to the relationship between cardiorespiratory fitness (CRF) level and cerebral oxygenation.

The influence of basic ventilation strategies and anesthetic techniques on cerebral oxygenation in the beach chair position: study protocol

BMC Anesthesiology, 2012
Background Beach chair positioning during general anesthesia is associated with a high incidence of cerebral desaturation; poor neurological outcome is a growing concern. There are no published data pertaining to changes in cerebral oxygenation seen with

Early effects of ventilatory rescue therapies on systemic and cerebral oxygenation in mechanically ventilated COVID-19 patients with acute respiratory distress syndrome: a prospective observational study

Critical Care, 2021
Background In COVID-19 patients with acute respiratory distress syndrome (ARDS), the effectiveness of ventilatory rescue strategies remains uncertain, with controversial efficacy on systemic oxygenation and no data available regarding cerebral ...

Spinal cord autoregulation using near-infrared spectroscopy under normal, hypovolemic, and post-fluid resuscitation conditions in a swine model: a comparison with cerebral autoregulation

Journal of Intensive Care, 2020
Background Few studies have investigated spinal cord autoregulation using near-infrared spectroscopy (NIRS). Here, we assessed spinal cord autoregulation under normal, hypovolemic, and post-fluid resuscitation conditions compared with cerebral ...

Cerebral Near-Infrared Spectroscopy and Electrical Cardiometry During Endotracheal Suction in Ventilated Infants Following Surgery: A Feasibility Study

Life
Background: Near-Infrared Spectroscopy (NIRS) and Electrical Cardiometry (EC) are promising non-invasive techniques for monitoring tissue oxygenation and hemodynamics, particularly in surgically ill infants who struggle to maintain cerebral oxygenation ...

Early biomarkers of brain injury and cerebral hypo- and hyperoxia in the SafeBoosC II trial. [PDF]

PLoS ONE, 2017
BACKGROUND:The randomized clinical trial, SafeBoosC II, examined the effect of monitoring of cerebral oxygenation by near-infrared spectroscopy combined with a guideline on treatment when cerebral oxygenation was out of the target range. Data on cerebral
