New Type of CPR Boosts Survival

Thursday, 13 April 2006 12:00 AM

A new kind of cardiopulmonary resuscitation substantially improves the survival rate for most patients who have an out-of-hospital heart attacks, according to a study at the University of Arizona.

Called cardiocerebral resuscitation (CCR), the new technique involves starting fast, powerful chest compressions as quickly as possible.

The rescuers skip the first steps of the standard protocol: intubating the patient for ventilation and delivering a shock using a defibrillator. While still attaching the victim to a defibrillator, they do not wait for the device to analyze the patient's heart rhythm, but start fast, forceful chest compressions.

Dr. Michael J. Kellum and his colleagues at the University of Arizona College of Medicine found that CCR nearly tripled survival rates during a one-year study.

The Arizona researchers also joined with the Wisconsin Emergency Medical Services Bureau teamed to test CCR in two Wisconsin counties during 2004 and 2005. That study also showed many more patients survived and many more who survived were completely free of brain damage.

"Intubating the patient and waiting for the defibrillator to do its analysis takes time -- time a cardiac arrest victim doesn't have," said Dr. Gordon A. Ewy, director of the University of Arizona Sarver Heart Center and senior author of the study.

Previous laboratory experiments showed that the most important factor for survival of cardiac arrest patients was to maintain blood flow through the body by continuous chest compressions, said Dr. Ewy.

"Stopping chest compressions for ventilations was far more harmful than helpful," he said. "Excessive ventilations during chest compression turned out to be harmful, too."

"I am convinced that cardiocerebral resuscitation will have a world-wide impact," Dr. Ewy said.

The Arizona study appears in The American Journal of Medicine.
