Summary of Monitoring Required for Hypothermia After Pediatric Cardiac Arrest Trials

Physiologic Studies

Arterial Line

Central venous catheter (or equivalent)

Temperature (central)

Esophageal (primary)

Chest radiograph (esophageal probe placement)

Rectal or foley (secondary)

Extracorporeal membrane oxygenation exception: 1 central temperature, any site

Laboratory Studies

Coagulation (prothrombin time/international normalized ratio, partial thromboplastin time) (q 24 hr)

Complete blood count (q 24 hr)

Arterial blood gas (q 24 hr), lactate (q 24 hr) × 3 d

Cultures
