warming protocol
Systematic approach to rewarming patients during separation from cardiopulmonary bypass.
Full Definition
A warming protocol is a structured approach to gradually rewarming patients from hypothermia during the separation from cardiopulmonary bypass. Most cardiac procedures involve controlled hypothermia for organ protection, and rewarming must be carefully managed to prevent complications such as bubble formation, hyperthermia, or rapid metabolic changes. The protocol typically specifies target temperatures, warming rates (usually 1-2°C per 10 minutes), and monitoring parameters. Effective rewarming is essential for optimal cardiac function, adequate hemostasis, and successful separation from bypass.
Usage
Usage note: Often institution-specific with standardized temperature targets and rates.
