“…Blood volume was measured by two independent indicators for PV and RBC, as recommended [16]. 51 Cr was used to measure RBC as this has been shown to be accurate even in patients with increased microvascular permeability [17]. RBC was similarly reduced in the two groups.…”

“…Plasma volume was measured by means of Evans blue [25]. Blood volume was calculated from plasma volume and haematocrit, using a body/venous haematocrit ratio of 0.91 [24]. Venous haematocrit was determined by the microhaematocrit method.…”

Peripheral blood flow and systolic blood pressure (strain-gauge plethysmograph), blood volume (Evans blue) and whole blood viscosity (cone-plate viscometer) have been measured in 66 premature and full-term infants 6 to 144h of age. Blood flow and blood volume were moderately decreased in the infants with respiratory distress. Highly significant (P less than 0.001) correlations were found between blood flow and blood volume (r = 0.77), blood pressure and blood volume (r = 0.50), peripheral resistance and blood volume (r = -0.44), blood flow and blood pressure (r = 0.50), blood flow and peripheral resistance (r = -0.67), peripheral resistance and blood viscosity (r = 0.45), and blood viscosity and haematocrit (r = 0.86). There was no correlation between peripheral blood flow and blood viscosity. However, at given blood volume, peripheral blood flow decreased with increasing blood viscosity. These results indicate that in newborn infants peripheral blood flow, blood pressure and peripheral resistance are influenced by blood volume, but also depend on blood viscosity.

Red cell mass (RCM) was estimated using 125I-labelled human serum albumin in 128 premature infants born after 26 to 36 weeks gestation. Infants of three different gestational periods (26--29, 30--32, and 33--36 weeks) with respiratory distress (RD) averaged lower one-minute Apgar scores and lower RCM than infants without RD (P less than 0.05). The incidence of RD was significantly (P less than 0.05) higher in infants with Apgar scores below 6 and in infants with RCM of less than 35 ml/kg than in the infants with greater values. The highest incidence of RD and the highest mortality rate were found in the infants with low Apgar scores and low RCM values. Prematures with similar Apgar scores showed a higher incidence of RD when RCM was low, and infants with similar RCM showed a higher incidence of RD when Apgar scores were low. Our results suggest that both birth asphyxia and deficiency of red cell mass interfere with postnatal cardio-respiratory adaptation. In high-risk premature infants, erythrocytes should be transfused when the venous haematocrit is below 0.459
