Patient warming prevents inadvertent perioperative hypothermia, which can cause vasoconstriction, tissue hypoxia and a decreased ability to fight infections. Perioperative warming also increases patient satisfaction and helps to reduce lengths of stay in the PACU. The benefits of warming patients are so obvious and well-documented the question is no longer Should you implement a comprehensive patient warming protocol? The question you should be asking is What should our warming program include? We spoke with two CRNAs who offered perspectives grounded in real-world experience and research to help answer that question.
