Influence of Hyperbilirubinaemia on Two Different Near Infrared Spectroscopy Devices

Influence of Hyperbilirubinaemia on Foresight and INVOS Oximetry Values in Pediatric Hepatic Transplantation

Protocol Near infrared spectroscopy liver transplants: comparison of two monitoring of Near infrared spectroscopy in pediatric liver transplant.

Hyperbilirubinaemia may interfere with oximetry values as measured by Near Infrared Spectroscopy devices. The number of wave lengths used by different devices can influence the oximetry values in adult patients. This has never been demonstrated in children with hyperbilirubinaemia scheduled for elective liver transplantation.The study will compare cerebral and somatic oximetry values measured by two different Near infrared spectroscopy devices (FORESIGHT and INVOS) and analyse the influence of bilirubin levels on these differences.
