Background:
Evaluation of outcome after CPR in severe hypothermic patients.
Design:
Perspective study from October 1995 to April 1996.
Setting:
First aid team of Italian Red Cross, Busto Arsizio (Varese), Italy.
Methods:
A population of 22 patients in cardiac arrest in which CPR was performed immediately after rescue team's arrival is studied. ECG, core temperature, SpO2 and MAP were monitored whereas vital parameters were present during Basic Life Support. Outcome after CPR was evaluated with GOS scale.
Results:
It has been observed that severe hypothermia and time of cardiac arrest impact on the clinical outcome after CPR. The high mortality rate after CPR with BLS standard is worsened by a core temperature < or = 33 degrees C.
Conclusions:
Severe hypothermia seems to have a dangerous effect upon outcome after cardiopulmonary resuscitation; heating systems for body temperature could prevent this situation improving CPR results.
