Longer Resuscitation Attempts Associated with Greater Success

Longer Resuscitation Attempts Associated with Greater Success

 

Longer resuscitation attempts are associated with higher rates of return of spontaneous circulation and survival to discharge, according to an observational study in the Lancet.

 

The study comprised some 65,000 patients experiencing cardiac arrest in 435 U.S. hospitals — generally large hospitals — that are members of a cardiac registry. To characterize the hospitals' length of resuscitation attempts, only the times for patients who did not survive the attempt were recorded. Hospitals in the highest quartile (median duration, 25 minutes) had higher rates of circulation return and survival to discharge than those in the lowest quartile (median duration, 16 minutes).

 

The authors say their data "suggest that standardization of a minimum length for resuscitation attempts could improve survival." They add that prolonging resuscitation by 10 or 15 minutes "might have only slight effects on resources once efforts have already begun, but could improve outcomes." And Lancet's commentators agree.
