zone of stasis
The intermediate burn zone with compromised but potentially salvageable tissue that may progress to necrosis without proper care.
Full Definition
The zone of stasis lies between the zone of coagulation and zone of hyperemia, characterized by severely compromised blood flow and tissue viability hanging in the balance. This tissue may survive with optimal care including fluid resuscitation, infection prevention, and avoiding further injury, or it may progress to full necrosis within 24-48 hours. The fate of this zone often determines the ultimate depth and severity of the burn injury. Proper management focuses on optimizing perfusion and preventing conversion to deeper injury.
Usage
Usage note: Critical zone that determines burn progression; requires careful monitoring and aggressive supportive care.
