“…In the present study we found that hemoglobine did not increase postnatally in Group B infants with fetal pH < 7.20 in contrast to the non-acidotic groups. This may be related to pooling the placental blood in the vaginal delivered distressed infant [2]. Our findings thus confirm earlier studies emphasizing the vital importance of stabilisation immediately after birth (7.25), especially in infants before 34 weeks of gestation.…”

“…It has been shown that arterial blood pressure in RDS is low [1,3,6,7] or normal [26][27][28]. This contradiction may be due to the fact that in these studies blood pressure was not related to the severity of the disease.…”

Heart rate, short-term heart rate variability, long-term heart rate variability (LTV), mean arterial blood pressure and R-to-pulse time were recorded in 28 infants during the acute phase of respiratory distress syndrome (RDS). The patients were classified by a clinical scoring system into three classes related to the severity of the disease. The LTV was initially significantly (p < 0.01) lower in infants with severe RDS (class III) than in those with moderate or mild disease (classes II and I). Only in class III the LTV increased significantly (p < 0.001) during recovery. Also the mean arterial blood pressure was decreased in class III during the first 24 h of life. The R-to-pulse time proved not to be related to the severity of RDS. Reasonable assistance was achieved by multiparametric circulatory monitoring: a considerably disturbed circulatory control (tendency to hypotension and attenuated chronotropic cardiac control) was observed in the most severe form of RDS. No specific circulatory therapy was applied on the basis of the findings.

“…Preterm infants with hyaline membrane disease have suboptimal values for blood volume from birth. 1 Adequate blood volume is necessary for adequate systemic oxygen transport and organ and tissue perfusion in the newborn. 2 The magnitude of the placental transfusion is dependent in part on the effects of gravity and the time of cord ligation.…”

Placental Transfusion: Umbilical Cord Clamping and Preterm Infants

et al. 2000

OBJECTIVE:To investigate the clinical effects of early versus late cord clamping in preterm infants. STUDY DESIGN:A total of 32 premature infants were prospectively randomized. The following parameters were measured: Initial spun hematocrit (Hct), hemoglobin (Hgb), red blood cell (RBC) counts, frequency of blood transfusions, peak serum bilirubin, mean blood pressure (MBP), oxygen index, intraventricular hemorrhage, and significant patent ductus arteriosus (PDA). RESULTS:Over the 4-week study period, the delayed cord clamping (DCC) group exhibited a decrease in the frequency of blood transfusion (p Ͻ 0.001) and also a decrease in albumin transfusions over the first 24 hours (p Ͻ 0.03). MBP in the first 4 hours was higher in the DCC group (p Ͻ 0.01), and there were statistically significant increases in Hct (21%), Hgb (23%), and RBC count (21%) compared with the early cord clamping group. The risks of patent ductus arteriosus, hyperbilirubinemia, or intraventricular hemorrhage were similar in both groups. Late clamping of the umbilical cord had little or no effect on the oxygen index. CONCLUSION:DCC significantly reduced the requirement for blood and albumin transfusion. It also increased the initial Hct, RBC count, Hgb levels, and MBP.
