For infants that have concerning features on history or physical, and are thus categorized as high-risk, further evaluation is warranted. This will vary greatly depending on the infants symptoms, but may include, urinalysis, complete blood count, imaging with chest x-ray, and laboratory screening for ingestion of medications or poisons.
Hemolytic disease of the newborn, also known as hemolytic disease of the fetus and newborn, HDN, HDFN, or erythroblastosis fetalis, [1] [2] is an alloimmune condition that develops in a fetus at or around birth, when the IgG molecules (one of the five main types of antibodies) produced by the mother pass through the placenta.
Titers of 1:4 or higher is considered critical for Kell (compared to 1:16 for most other antibodies) and is considered to confer a high risk of fetal anemia. [17] Such high titers may be managed by weekly follow-up by obstetric ultrasound , assessing the peak systolic velocity of the fetal middle cerebral arterial (MCA), amniotic fluid volume ...
A rise in the reticulocyte count can mean that an infant may not need additional transfusions. [18] Low reticulocyte count is observed in infants treated with IUT and in those with HDN from anti-Kell [16] Neutrophils - as Neutropenia is one of the complications of HDN, the neutrophil count should be checked. [9] [10]
Delivery Before 37 Weeks - premature infants require more medical intervention and have less effective immune defenses, so these neonates are at increased risk of infection Prolonged Rupture of Membranes (PROM) - the amount of time between the rupture of amniotic membranes and delivery of the neonate is directly correlated with risk of neonatal ...
One study suggested that a transient platelet activation of the infant's portal system is responsible for this hyperammonemia. [5] Another study proposed that this occurs due to a shunting of blood away from the portal system of the liver through the ductus venosus directly into the systemic circulation.
In their study, Kirolos and his fellow researchers followed up on a group of 1,024 children in Blantyre, Malawi, one, seven and 15 years after they were treated in hospital for acute malnutrition ...
Transient tachypnea of the newborn occurs in approximately 1 in 100 preterm infants and 3.6–5.7 per 1000 term infants. It is most common in infants born by caesarian section without a trial of labor after 35 weeks of gestation. Male infants and infants with an umbilical cord prolapse or perinatal asphyxia are at higher risk.
