Abstract

The haematocrit values in 51 babies were studied to observe the possible variations due to the method and time of sampling and to relate these findings to blood viscosity. A good correlation (r = 0,9536) between haematocrit values of warmed heel capillary blood and of central venous samples was found. Prediction of venous value from a known sample of capillary blood can be made using regression lines and 95% confidence limits. The correlation between venous and unwarmed blood samples from the heel is not as good. A central venous haematocrit value of 65% or greater gave a 100% risk of the infant's blood being hyperviscous. Hyperviscosity occurred in 71% of infants with a capillary haematocrit value of 65 - 68% but the figure rose to 81% when the peripheral haematocrit value was 68% or more.

摘要

对51名婴儿的血细胞比容值进行了研究，以观察由于采样方法和时间可能产生的变化，并将这些结果与血液粘度相关联。发现温热足跟毛细血管血和中心静脉血样本的血细胞比容值之间具有良好的相关性（r = 0.9536）。可以使用回归线和95%置信区间，根据已知的毛细血管血样本预测静脉血值。足跟静脉血样本与未温热血样本之间的相关性则没那么好。中心静脉血细胞比容值达到或超过65%时，婴儿血液出现高粘度的风险为100%。毛细血管血细胞比容值在65%至68%之间的婴儿中，71%出现了高粘度，但当外周血细胞比容值达到或超过68%时，这一比例升至81%。
