Abstract

Very few previous studies have been conducted on the prognostic factors among postcardiac arrest patientswho were not witnessed. Therefore, we investigated the factors governing the prognosis of postcardiac arrestresuscitation patients without witnesses: we retrospectively investigated the predictive factors governing the vitaland neurological prognosis of out-of-hospital postcardiac arrest resuscitation patients admitted between January2015 and May 2019 who had no witnesses. A total of 857 cases were analyzed. It was found that the predictors ofgood vital and neurological prognosis in postresuscitation patients with unwitnessed out-of-hospital cardiac arrestwere young age, return of spontaneous circulation during transport, bystander cardiopulmonary resuscitation, andshockable initial rhythm. Considering these results, we believe these measures should be considered to improvethe life-saving rate.
