TABLE 90.7 MANAGEMENT OF HYPOTHERMIA Initial management Provide supplemental oxygen Cardiopulmonary resuscitation for asystole, ventricular fibrillation, or any nonperfusing rhythm (use Echo to distinguish PEA from perfusing rhythm if pulses are not palpable) Laboratory determinations Arterial blood gas analysis corrected for temperature Complete blood cell count, platelet count Prothrombin time, partial thromboplastin time Electrolytes, blood urea nitrogen, creatinine, glucose Amylase, Lipase Urine drug screen Monitoring Heart rate, electrocardiogram, respiratory rate, blood pressure Temperature Consider central venous pressure Treatment Correct hypoxemia, hypercarbia Correct hypokalemia Correct hypoglycemia, dextrose 0.5–1 g/kg IV Tolerate hyperglycemia Temperature ≥32°C (89.6°F): passive rewarming or simple external rewarming
