Abstract 2834: Outcomes and Mid-term Survival of In-hospital Adult Cardiopulmonary Resuscitation Assisted With Portable Auto-priming Percutaneous Cardiopulmonary Support
Background - Outcomes from in-hospital cardiopulmonary resuscitation (CPR) are unsatisfactory. CPR assisted with percutaneous cardiopulmonary support (PCPS) is expected to improve outcomes in patients who require CPR.
Methods We retrospectively analyzed 83 consecutive cases of adult in-hospital CPR assisted by a portable pre-assembled auto-priming PCPS system (EBS, Terumo, Japan) from January 2004 to December 2007.
Results - PCPS was successfully performed in 97.6% of the patients and could be weaned in 57.8% of the patients. The survival-to-discharge rate was 41.0% with an acceptable neurological status in 85.3% of the patients. The 6-month survival was 38.6%. In-hospital survival decreased about 1% for each one minute increase in the duration of CPR. The probability of survival was about 65%, 45%, and 19% when the duration of CPR was 10, 30, or 60 minutes, respectively. A multivariate analysis revealed that defibrillation and CPR duration less than 35 minutes were independent predictors for both in-hospital survival and 6-month survival (P<0.05).
Conclusions - Our results showed that CPR assisted with PCPS results in an acceptable in-hospital survival rate and mid-term prognosis. The currently accepted duration of CPR would be extended with the assistance of PCPS.
