Harrison, K. L. (1979) Aust. Paediatr. J., 15, 96–97. Fetal erythrocyte lifespan. The demonstration of fetal erythrocytes in the maternal circulation by the Kleihauer technique after feto‐maternal macrotransfusion provides a means of measuring the lifespan of those cells produced at the time of the haemorrhage. Two cases of massive feto‐maternal haemorrhage at 40 weeks gestation and one at 36 weeks gestation are used, together with a published case at 34 weeks gestation. to show that… 

Dynamics of hematologic parameters and of the erythrocyte deformability index at the juvenal period of rats and guinea pigs

In experiments on Wistar rats and guinea pigs, dynamics of blood hematological parameters and of erythrocyte deformability index (DI) was studied from birth to the 3-month age, and like in the case with rats, DI had a close correlation with the ery Throcyte parameter of shape (Omin).

A review of neonatal jaundice

There is a requirement for accurate total bilirubin measurement from <100 to >500 μmol/L, with sufficient precision to assess the rate of bilirubsin change with time, to identify those infants at risk of jaundice.

STUDY OF CORRELATION OF ABO AND RH INCOMPATIBILITY WITH RISK OF NEONATAL HYPERBILIRUBINEMIA IN A TERTIARY CARE HOSPITAL

In ABO incompatibility, if jaundice develops, it remains in physiological limits, so prevention of aggravating factors is very important, in case of ABO and Rh incompatibility.

The feasibility and cost of neonatal screening for prenatal alcohol exposure by measuring phosphatidylethanol in dried blood spots.

Results indicate that screening for PAE in DBS cards is a feasible procedure and that a majority of infants have enough blood after the routine heel prick to fill an additional card, and that screening by PEth analysis from DBS Cards is cost-efficient.

Hyperbilirubinema is Treated Using L.E.D Phototherapy for Neonatals

The aim of this project is to create a LED phototherapy circuit unit having high competence, low thermal emission, and for extended term usage than other phototherapy methods.

Association of ABO and Rh incompatibility with neonatal hyperbilirubinaemia

In ABO incompatibility, if jaundice develops, it remains in physiological limits, and in presence of some aggravating conditions may present as pathological jaundices, which results in significant morbidity but no mortality.

The findings suggest that studies of the intrauterine haemolysis do not always give true indication of the degree of foetal anaemia, and that the haemoglobin concentration is not always a reliable index of the rate of ha Hemolysis.

A highly significant increase in mean corpuscular volume in the infants of smoking mothers was observed which did not appear to be related to the number of cigarettes used, and a possible mechanism for this is postulated.

Massive feto-maternal hemorrhage as a cause of perinatal mortality and morbidity.

A series of Rh-negative primiparae has been studied in order to gain further insight into the process of immunization by pregnancy, and there is evidence of a direct relation between the count of foetal cells after delivery and the risk of developing antibodies.
