Variability of deformation and aggregation properties of erythrocytes is a component part of nonspecific antihypoxic response of formation of adequate blood flow in the tissues and efficiency of the microcirculation in different sections of the vascular bed. Degree of change in these properties during neonatal adaptation to spontaneous breathing can be a marker of its abnormality. We examined 19 healthy full-term newborns in the first 1-2 and 13 children in the first 5-7 days of life. The control group consisted of 30 healthy people aged 25-35 years. It is shown that the aggregation properties of erythrocytes, reduced on the birthday, significantly increased to 5-7 day to values in adults. Erythrocyte deformability in neonates enhanced by an excess reserve of specific surface and reduced strength of the membranes to stretch. Adapting to the transition to spontaneous breathing accompanied by an emphasis on the hyperkinetic type of hemodynamics. |
