Patient's question:
Both hands and feet are extremely cold, and the skin has turned purplish. I quickly called a doctor to check, and they said it's a sign of neonatal shock. I'd like to learn more about the main characteristics of this condition, including the primary clinical manifestations when the disease occurs. What are the main clinical symptoms of neonatal shock?Doctor's answer:
Symptoms of neonatal shock 1. Early stage This stage is the compensatory phase of shock, also known as the microcirculatory spasm stage. Under the action of bacteria and their toxins, the body's sympathetic nervous system is excited, leading to vasoconstriction. Vessels in the skin and abdominal viscera constrict, reducing blood circulation to ensure blood supply to vital organs such as the heart and brain, temporarily maintaining life. This stage primarily exhibits signs of vasoconstriction, such as pale skin and cool extremities (reaching the elbows in the upper limbs and knees in the lower limbs). Heart rate increases, reaching 160/min at rest. Brain hypoxia manifests as decreased responsiveness (lethargy, sluggishness), which is of great significance for early diagnosis of shock. 2. Middle stage This stage is the decompensatory phase of shock, also known as the microcirculatory stasis stage. Due to prolonged microvascular constriction, tissue hypoxia occurs, anaerobic metabolism increases, and lactic acid production becomes excessive.
