To assess the prognosis of patients with return of spontaneous circulation after cardiac arrest by shock index and adjusted shock index / 中华急诊医学杂志

ABSTRACT

Objective To examine the usefulness of shock index (Sl) and adjusted shock index (corrected to temperature) (ASI) in predicting prognosis of patients with return of spontaneous circulation after cardiac arrest.Methods A prospective study,which data such as vital signs of the cases were collected by the Utstein template,was conducted in 111 of cases with return of spontaneous circulation after cardiac arrest to assess the value of SI and ASI for predicting their prognoses.Results There was no evidence to show difference between the cases with survival to hospital discharge and the ones who died about systolic blood pressure and heart rate (P ＞0.05).SI and ASI [(1.109 ±0.428) and (1.082 ±0.410)] of the group of death were higher significantly than the ones [(0.899 ± 0.303) and (0.844 ± 0.265)] of the group with survival to hospital discharge,P ＜ 0.05.The risk of death was elevated in the group with ASI ＞ 1.1,which odds ratio (5.4) higher than the ones of systolic blood prcssure ＜90 mm Hg (1.6)and ventricular rat ＞ 100 beat/min (3.1) significantly.The odds ratio of death with AS ＞ 1 was 2.8.Conclusions Shock index and adjusted shock index are easy to derive and conducive to predict effectively diseases prognosis such as survival to hospital discharge or death of patients with ROSC.
