Measuring total hemoglobin(tHb) is a precious step to decide to start or to stop transfusion during operation. The newly developed instrument pulse CO-Cooximetry (Masimo) makes noninvasive monitoring of venous hemoglobin level (SpHb).

The objective of this study

  • to compare the simultaneous level of tHb and SpHb during operation and after volume expansion in children
  • to assess the accuracy of amount of acute change of SpHb on Masimo and tHb

Continuous Hemoglobin Measurement

Study Type: Observational
Study Design: Observational Model: Case-Only
Time Perspective: Prospective

Further study details as provided by Jin-Tae Kim, Seoul National University Hospital:

Primary Outcome Measures:
  • hemoglobin concentrations from laboratory lab and pulse Co-oximetry [ Time Frame: before and after volume expansion (20 minutes) ]
    volume expansion will be performed for 20 minuntes
