Brief Summary
Controlled therapeutic hypothermia is a method of preserving neurological function post-resuscitation.It has been associated with improved functional recovery and reduced histological deficits in animal models of cardiac arrest.

External Cooling
ACTIVE COMPARATORThe gel-coated external cooling device consists of four water circulating gel coated energy transfer pads, and is placed on the patient's back, abdomen, and both thighs. Depending on the size used, the total surface area ranges between 0.60 and 0.77 m2. It is connected to an automatic thermostat controlling the temperature of the circulating water (4°C to 42°C) based on the patient's core temperature.
Internal Cooling
ACTIVE COMPARATORThe intravascular cooling system uses a single lumen (8.5 Fr,38 cm) central venous catheter inserted into the inferior vena cava via the left or right femoral vein. Normal saline is pumped through three balloons mounted on the catheter and returned to a central system in a closed loop. The saline flow within the balloons is in close contact with the patient's blood flow and serves as a heat exchange system. An automatic temperature control device adjusts the temperature of the circulating saline (4°C to 42°C) based on the patient's core temperature.
