Study Notes
Hemolytic Disease of the Newborn
- Hemolytic Disease of the Newborn is a condition where the mother's immune system produces antibodies against the fetus's red blood cells, leading to their destruction.
- One of the major risk factors is a previous pregnancy or blood transfusion that sensitized the mother to the Rh antigen.
- It occurs when an Rh-negative mother is carrying an Rh-positive fetus.
- The primary cause is the incompatibility between the mother's Rh-negative blood and the fetus's Rh-positive blood.
- The approximate annual incidence is not specified.
- The condition is associated with jaundice and anemia.
Pathophysiology and Diagnosis
- The main pathophysiological process is the production of antibodies against the Rh antigen, leading to the destruction of fetal red blood cells.
- The definitive diagnostic criterion is the presence of antibodies or complement proteins attached to the surface of red blood cells.
- The investigation used to detect these antibodies is the direct Coombs test.
Clinical Features and Management
- Clinical features commonly associated with Rh hemolytic disease include jaundice, anemia, and hydrops fetalis.
- The main goal of jaundice management is to prevent kernicterus.
- The immediate resuscitation therapy for live-born infants is phototherapy.
- The primary preventive measure for Rh-negative mothers is to administer anti-Rh IgG antibodies during pregnancy.
Complications and Prevention
- A complication not typically associated with Rh hemolytic disease is hypoglycemia.
- Delivery in advance is indicated for unborn infants with Rh hemolytic disease when fetal distress or hydrops fetalis occurs.
- A rare occurrence during the first pregnancy involving an Rh-positive fetus is the development of anti-Rh IgG antibodies.
Hypoglycemia in Neonates
- Hypoglycemia is indicated by a blood glucose level below 2.6 mmol/l.
- A condition that can lead to increased glucose consumption and contribute to hypoglycemia is sepsis.
- The primary cause of hypoglycemia in neonates with inborn errors of metabolism is impaired glucose metabolism.
- Clinical features that can be used to suspect hypoglycemia include jitteriness, lethargy, and seizures.
- The rate at which neonates' skin temperature falls after birth is 0.5°C per hour.
- Neonates have a higher rate of heat loss compared to adults due to their larger surface-to-volume ratio.
- A clinical feature not commonly associated with neonatal hypoglycemia is hypertension.
Management of Hypoglycemia and Hyperglycemia
- The immediate management approach for symptomatic newborns with RBG < 2.6 mmol/l is to administer glucose.
- If a newborn still has hypoglycemia after 1 hour despite initial management, consider underlying causes such as inborn errors of metabolism.
- The threshold for considering treatment for hyperglycemia in neonates is a glucose level above 11 mmol/l.
- The primary cause of hyperglycemia in neonates is stress, such as during birth asphyxia or respiratory distress.
- The initial approach to managing hyperglycemia is to stop any glucose infusions.
- If glucose levels are still above 11 mmol/l after stopping D10% infusion for 4 hours, consider administering insulin.
