Abstract:
Objective To investigate the prognostic value of red cell distribution width(RDW)on neurological prognosis in patients with cardiac arrest(CA).Methods Retrospective analysis the case data,RDW and biochemical indicators of 107 CA patients treated in our department(January 2020 to November 2023).According to cerebral performance category(CPC),patients were divided into good neurological prognosis group and bad neurological prognosis group.The differences in clinical data and RDW between the two groups were compared.Multivariate Logistic regression analysis was used to investigate the risk factors on neurological prognosis.Predictive effect of RDW on poor neurological prognosis in CA patients was assessed by receiver operating characteristic(ROC)curve.According to the optimal cut-off value of RDW,it was divided into high RDW group(≥ 13.45％)and low RDW group(＜13.45％)to compare the incidence of poor neurological prognosis.Results Totally 107 CA patients were included,34 patients in the good neurological prognosis group and 73 patients in the bad neurological prognosis group,the incidence of poor prognosis of neurological function was 68.22％.Compared with good neurological prognosis group,the acute physiology and chronic health evaluation Ⅱ score,RDW,cardiopulmonary resuscitation(CPR)time,age,serum sodium and glutamic-pyruvic transaminase in bad neurological prognosis group were significantly increased(P＜0.05).Multivariate Logistic regression analysis showed that RDW,age and CPR time were independent risk factors for poor prognosis of neurological function(P＜0.05).ROC curve analysis showed that the area under the curve of RDW to predict poor neural function prognosis in CA patients was 0.766.When the optimal threshold of RDW was 13.45％,the sensitivity was 73％and the specificity was 71％.The incidence of poor prognosis of neurological function in high RDW group was 84.13％,which was significantly higher than 45.45％in low RDW group(P＜0.05).Conclusion Elevated RDW is an independent risk factor for increased risk of poor neurological outcomes in patients with CA.It has certain predictive value for neurological outcomes in patients with CA.
