BACKGROUND: Outcome from in-hospital cardiopulmonary resuscitation (CPR) is still unsatisfactory. CPR assisted with percutaneous cardiopulmonary support (PCPS) is expected to improve the outcome of in-hospital 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%. Survival-to-discharge decreased about 1% for each 1 min 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 min, respectively. Multivariate analysis adjusted with clinical factors including organ dysfunction severity scores revealed that defibrillation and CPR duration less than 35 min were independent predictors for both survival-to-discharge (odds ratio=8.0, 95% CI=2.8-23.0, p<0.001) and 6-month survival (hazard ratio=3.3, 95% CI=1.9-5.9, p<0.001). CONCLUSIONS: Our results showed that CPR assisted with PCPS results in an acceptable survival-to-discharge rate and mid-term prognosis.
