Detailed Description
Extremely preterm (EPT) infants are subjected to a sample-related withdrawal of whole blood of 50 % of total blood volume during the first 2 postnatal weeks and a transfused volume of 100 % of total blood volume with donor blood during the corresponding time period. The resulting decrease in the proportion of fetal hemoglobin is strongly associated with morbidity outcome, especially broncho-pulmonary dysplasia (BPD), in the EPT infant.
This randomized trial evaluates if a reduction in sample-related blood volume loss by 50% during the first two postnatal weeks leads to a reduced rate of BPD in EPT infants. Half of the included infants will be subjected to clinical blood sampling using micromethods during the first two postnatal weeks whereas blood sampling in the other half of infants will be performed using standard clinical methods.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Micromethods for blood sample analysis
Blood gases are analysed using 0.045 ml whole blood Levels of C-reactive protein (CRP) are analysed using 0.010 ml whole blood
|
Micromethods in the intervention arm are applied aiming to achieve a mean reduction of 50 % of sampled blood volume during the first two postnatal weeks as compared to standard clinical blood sampling analyses
|
No Intervention: Standard clinical methods for blood sample analysis
Blood gases are analysed using 0.3 ml whole blood Levels of CRP are analysed using 0.5 ml whole blood
