Cerebral Oximetry in Newborns - Comparing INVOS 5100 and FORE-SIGHT Cerebral Oximeters

Cerebral Oximetry in Newborns - Comparing INVOS 5100 and FORE-SIGHT Cerebral Oximeters Absolute Values, Sensitivity for Low Oxygen Levels and Reproducibility..

Regional tissue oxygenation (rStO2) can be monitored by near infrared spectroscopy. The commercial devices FORE-SIGHT (CASMED) and INVOS (COVIDIEN) will be used simultaneously to test for their relative sensitivity for low oxygen levels just after birth on term infants born by elective cesarean section. Reproducibility will be examined by replacements of the sensors six times the next day when the infant is stable and quiet. Neonatal sensors will be used.

Inclusion Criteria:

• Term infants (age more than 37 weeks of gestation)
• Elective cesarean section after an uncomplicated pregnancy

Exclusion criteria:

• Thick hair that makes good measurements difficult/impossible
• Obvious malformations or syndrome
• Complications in relation to the cesarean section
• Depression after birth (APGAR < 8 after 1 minute)
