ICD-11 8B24 — Hypoxic-ischaemic encephalopathy
Brain damage due to hypoxia-ischemia: Previous term Anoxic brain damage has been changed. The new term is now widely accepted, and better describes the pathophysiology, i.e., the combination of complete and incomplete transitory global cerebral ischemia together with a combination of anoxia and hypoxia. In a surviving patient, pure anoxic encephalopathy is very uncommon.
The diagnosis includes nothing.
It excludes 6 items.
