The precise mechanism of acrocyanosis is not known. [6] The current line of thinking goes that vasospasms in the cutaneous arteries and arterioles produce cyanotic discoloration, while compensatory dilatation in the postcapillary venules causes sweating. Arteriovenous subpapillary plexus shunting also occurs.
When obtaining the history, it is important to determine the timing of symptoms and to ask about risk factors/exposures, such as prenatal history or access to well-water. [29] Pulse oximeter on infant's foot. On physical exam it is important to visualize where the cyanosis is present to differentiate between peripheral and central cyanosis ...
Traumatic asphyxia is characterized by cyanosis in the upper extremities, neck, and head as well as petechiae in the conjunctiva. Patients can also display jugular venous distention and facial edema. [3] Associated injuries include pulmonary contusion, myocardial contusion, hemo/pneumothorax, and broken ribs. [4] [5]
