Resuscitation

We report the case of a victim of deep accidental hypothermia who was extracted from the ice and received 1.5 h of mechanical chest compression. This was followed with rapid rewarming on cardiopulmonary bypass and resulted in good physical and mental recovery. This management option should be considered for similar victims.

During recent years, in-hospital cardiopulmonary resuscitation (CPR) management has received much attention. However, the rate of survival after in-hospital resuscitation in Iran hospitals is not known. Therefore, a study was designed to evaluate the outcome of in-hospital cardiopulmonary resuscitation (CPR) in the city of Kashan, Iran, during a 6-month period during 2002. ⋯ Our study showed that it needs more attention to be paid to cardiopulmonary resuscitation management in Iran's hospitals. The results of this study could be an important first step toward a national study on the survival after cardiopulmonary resuscitation to provide accurate data on our performance with regards to the chain of survival.

An impedance threshold valve (ITV) is a new airway adjunct for resuscitation that permits generation of a small vacuum in the chest during the recoil phase of chest compression. ⋯ An ITV can augment perfusion during CPR. The observed effectiveness of ITVs in the laboratory and in the clinic suggests a thoracic pump mechanism for Standard CPR, and perhaps also an effective compression threshold that must be exceeded to generate blood flow by external chest compression.

Comparative Study
Induction of mild hypothermia with infusion of cold (4 degrees C) fluid during ongoing experimental CPR.
Therapeutic hypothermia after resuscitation has been shown to improve the outcome regarding neurological state and to reduce mortality. The earlier hypothermia therapy is induced probably the better. We studied the induction of hypothermia with a large volume of intravenous ice-cold fluid after cardiac arrest during ongoing cardiopulmonary resuscitation (CPR). ⋯ Inducing hypothermia with a cold infusion seems to be an effective method that can be started even during ongoing CPR. This method might warrant consideration for induction of early therapeutic hypothermia in cardiac arrest victims.
