Fetal and neonatal pathology.

Fetal and neonatal thermoregulation.

The metabolic rate of the fetus per tissue weight is relatively high when compared to that of an adult. Moreover, heat is transferred to the fetus via the placenta and the uterus, resulting in a 0.3 degrees C to 0.5 degrees C higher temperature than that of the mother. Therefore, fetal temperature is maternally dependent until birth. At birth, the neonate rapidly cools in response to the relati...

Fetal and Neonatal Arrhythmias.

Cardiac arrhythmias are an important aspect of fetal and neonatal medicine. Premature complexes of atrial or ventricular origin are the main cause of an irregular heart rhythm. The finding is typically unrelated to an identifiable cause and no treatment is required. Tachyarrhythmia most commonly relates to supraventricular reentrant tachycardia, atrial flutter, and sinus tachycardia. Several an...

Fetal and neonatal alloimmune thrombocytopenia.

UNLABELLED Fetal and neonatal alloimmune thrombocytopenia (FNAIT) is the commonest cause of severe neonatal thrombocytopenia. FNAIT is usually suspected in neonates with bleeding or severe, unexplained, and/or isolated postnatal thrombocytopenia. Affected fetuses should be managed in referral centers with experience in the ante-natal management of FNAIT. Close collaboration is required between ...
