Safety and Feasibility of Endovascular Cooling Device in Patients With Hypothermic Cardiopulmonary Resuscitation

November 21, 2005 updated by: National Taiwan University Hospital
Hypothermic resuscitation is proven to be benefit to the cardiac origin cardiac arrest patients for it improve brain recovery dramatically. However, traditional cooling devices and methods, most external cooling methods, include ice blanket, cooling helmet, or ice packing lower the body temperature slowly or inefficiently which make many emergency physicians hesitate to perform hypothermic resuscitation. To improve and promote the practice of hypothermia resuscitation, more efficient temperature control method is necessary. We conduct this clinical trial to evaluate the safety and feasibility of internal cooling catheter and temperature regulatory device, which is approved by FDA in neurologic ICU for temperature control, in the cardiac arrest patients.

Detailed Description

We recruited successful resuscitated nontraumatic cardiac arrest adult patients in the emergency department to evaluate the safety and feasibility of application those invasive internal temperature regulator devices. Internal cooling catheter, "ICY" , and thermal regulator device, "Coolguard 2000" are applied to the patients from femoral vein. WE definite 4 stages according to the temperature during the clinical trial: "The Cooling Phase", "Hypothermia phase", "Rewarming phase", and "Postrewarming phase". The temperature is lowed or elevated by the rate 0.5C/hr during the Cooling and Rewarming Phase, and it is maintained 33 +/- 1 C during hypothermia phase for 12 hours according to the comment of ACLS. To understand the safety and feasibility, regular blood sampling, bedside EEG and vital monitors, and special sheets are designed to document the every reasons, time points or every clinical events during hypothermia therapy. The patients is observed until rewarming finish for 48 hours or till death if expired during post-resuscitation hypothermia therapy.
