Definition A generic term for a resuscitation technique used to manage patients with moderate/severe hypothermia, which consists of increasing the non-acral temperature of the body.
Without circulatory collapse Patient airways are warmed with heated, humidified air by O2 mask or endotracheal tube, eliminating respiratory heat loss, and increasing body temperature by 1–2ºC/hour. Blood volume is expanded with warmed (40–42ºC) IV solutions.
Other methods of core rewarming include peritoneal lavage with heated dialysate or closed pleural irrigation with warm saline.
With haemodynamic instability Cardiopulmonary bypass; advantages include ability to maintain perfusion and oxygenation as rapid rewarming occurs and recuperation of myocardial function.
