Understanding Shock: Ten Important Facts

Rewarming is an important part of the resuscitation plan for small patients. As body temperature falls, adrenergic receptors are theorized to become refractory to catecholamine release. Therefore active rewarming is indicated for patients with moderate to severe hypothermia. Use forced warm air blankets, incubators, circulating warm water blankets, and/or…
