A Comparison of Three Methods of Hemoglobin Monitoring in Pediatric Patients

Hemoglobin Monitoring During High Bleeding Risk Surgery in Pediatric Patients: Equivalence Study of Hemoglobin Transcutaneous Saturation and Hemocue With Total Serum Hemoglobin

Investigators compare the accuracy of the SpHb and hemocue with blood Hb levels

The goal of the study is to compare 3 methods of hemoglobin measurement in pediatric patients undergoing major surgery. During general anesthesia investigators will measure and compare at different periods of time blood hemoglobin levels obtained from a radial artery catheter with 2 non invasive methods of measurement using hemocue and SpHb

Inclusion Criteria:

• Paediatric patients scheduled for surgery under general anesthesia
• Arterial catheter necessary in the anesthetic protocol
• BMI<30
• Written consent of holders of parental authority
• No opposition of children

Exclusion Criteria:

- Hemoglobine disease
