[Hematocrit in venous and capillary blood in children in shock]
Insights
Hematocrit measurements in infants revealed significant differences between blood samples from the jugular vein and heel in shocked infants compared to healthy ones. This difference in hematocrit levels indicated prognosis in infant shock.
Area of Science:
- Pediatric Medicine
- Neonatology
- Clinical Pathology
Background:
- Hematocrit measurement is crucial for assessing hydration and oxygen-carrying capacity.
- Accurate hematocrit values are vital for managing critically ill infants, particularly those in shock.
Purpose of the Study:
- To compare hematocrit measurements from external jugular vein and heel blood samples in shocked infants.
- To evaluate the diagnostic and prognostic value of these hematocrit differences in infant shock.
Main Methods:
- Hematocrit was measured every 8 hours in 20 shocked infants and 10 healthy infants.
- Blood samples were simultaneously collected from the external jugular vein and via heel puncture.
Main Results:
- Healthy infants showed an average hematocrit difference of 5.3% between the two sampling sites.
- Shocked infants exhibited a significantly larger average difference of 25.7%.
- A persistent large difference (28.8%) in shocked infants correlated with mortality, while a reduced difference (8.8%) indicated survival.
Conclusions:
- Discrepancies in hematocrit measurements between jugular vein and heel blood are pronounced in shocked infants.
- The degree of this hematocrit difference can serve as a prognostic indicator in pediatric shock management.
Abstract:
Hematocrit was measured every 8 hours in the bloods of 20 shocked infants and in 10 healthy cases. Samples of blood were taken at the same time from the external jugular vein and following puncture on the heel. Whereas the difference of both measurements was 5.3% as an average in healthy cases, in patients it was of 25.7%. At the end of eight hours of treatment, there was still a difference of 28.8% in patients who finally died, but it dropped tp 8.8% in those who survived.
