Haemoglobin Measurement for Babies

Not Applicable
Completed
Conditions
Infant
Hemoglobins
Non-invasive
Registration Number
NCT02722759
Lead Sponsor
Johannes Gutenberg University Mainz
Brief Summary

In this prospective study different methods of haemoglobin measurement in term and preterm neonates are compared with the gold standard. Non-invasive haemoglobin measurement with the Radical-7® (SpHb, Masimo®), point-of-care haemoglobin-measurement (HcHb, HemoCue@, Radiometer), blood-gas-analysis (BGAHb,ABL800®, Radiometer) are compared with haemoglobin measurement by an automated hematology analyzer (labHb, Siemens Advia®).

Detailed Description

Neonates admitted to neonatal intensive care unit or to a normal neonatal ward are enrolled in the study, if parents have given their written informed consent. Non-invasive SpHb measurements are recorded prior to routine venous sampling. Routine venous sampling includes labHb and BGAHb. Additionally HcHb is taken from the routine venous sampling (HcHbart/ven) and from an additionally capillary puncture of earlobe or heel (HcHbcap). Every neonate can participate in two measurements.

Primary Outcome Measures
NameTimeMethod
accuracy of different methods (SpHb, HcHb,BGAHb) of haemoglobin measurement compared with the gold standard labHbthrough study completion, an average of 3 months

accuracy is assessed by Bland-Altman-method of comparison, by Root mean square error and by out of range

Secondary Outcome Measures
NameTimeMethod
handling of the SpHb-devicethrough study completion, an average of 3 months

measurement of how often the Radical-7 has to be replaced and of the time until a stable Signal appears

influence of weight and gender on accuracy of SpHbthrough study completion, an average of 3 months

correlation of PI with the accuracy of SpHb

influence of PI (perfusion index) on accuracy of SpHbthrough study completion, an average of 3 months

correlation of PI with the accuracy of SpHb

influence of concentration of HbF on accuracy of SpHb,BGAHb, HcHbthrough study completion, an average of 3 months
