Area of Science:

  • Biomedical Engineering
  • Clinical Monitoring
  • Medical Technology

Background:

  • Near infrared spectroscopy (NIRS) is an evolving non-invasive optical technique.
  • It measures tissue oxygenation and haemodynamics by detecting light absorption.
  • NIRS technology is still in its early stages of development.

Purpose of the Study:

  • To evaluate the application of NIRS for monitoring cerebral haemodynamics and oxygenation.
  • To explore the utility of NIRS in various clinical settings, including neonatal care and surgery.

Main Methods:

  • Utilizes near-infrared light to assess tissue oxygenation and blood flow.
  • Non-invasive monitoring at the patient's bedside.
  • Application in diverse scenarios such as neonatal intensive care and cardiac surgery.

Main Results:

  • Demonstrated feasibility of measuring cerebral haemodynamics and oxygenation in preterm infants.
  • Successfully observed cerebral oxygenation changes during birth and cardiac surgery.
  • NIRS provides valuable physiological data in critical care settings.

Conclusions:

  • Near infrared spectroscopy is a promising research tool for understanding cerebral physiology.
  • NIRS has potential clinical applications in monitoring vulnerable patient populations.
  • Further development is needed to establish NIRS as a routine clinical diagnostic tool.
