A 3.8-kg infant was delivered vaginally at 39 weeks after a 30-minute second stage. There was a nuchal cord
After birth the infant is noted to have petechiae over the face and upper back. Information given to the infant's parents should be based on the knowledge that petechiae:
a. Are benign if they disappear within 48 hours of birth.
b. Result from increased blood volume.
c. Should always be further investigated.
d. Usually occur with forceps delivery.
ANS: A
Petechiae, or pinpoint hemorrhagic areas, acquired during birth may extend over the upper por-tion of the trunk and face. These lesions are benign if they disappear within 2 days of birth and no new lesions appear. Petechiae may result from decreased platelet formation. In this situation the presence of petechiae is most likely a soft-tissue injury resulting from the nuchal cord at birth. Unless they do not dissipate in 2 days, there is no reason to alarm the family. Petechiae usually occur with a breech presentation vaginal birth.
