acrocyanosis
Pronunciation: /ˌækroʊsaɪəˈnoʊsɪs/
Bluish discoloration of the hands and feet in newborns, typically benign and related to immature circulation.
Full Definition
Acrocyanosis refers to the bluish or purplish discoloration of the extremities, particularly the hands and feet, commonly observed in newborns during the first few hours to days of life. This condition results from immature peripheral circulation and vasoconstriction in response to cool temperatures. Unlike central cyanosis, acrocyanosis is generally benign and resolves as the infant's circulatory system matures. However, persistent or worsening acrocyanosis may indicate underlying cardiopulmonary issues requiring further evaluation. Documentation should distinguish between normal transitional acrocyanosis and pathological cyanosis.
Usage
Usage note: Distinguish clearly from central cyanosis in clinical documentation as management differs significantly.
