Abstract:
Objective To explore the risk factors influencing the prognosis of patients with acute poisoning by analysis of clinical data of 356 patients in order to provide the scientific evidence for planning therapeutic strategies in ICU.Methods The clinical data of 356 patients with acute poisoning were collected during the period from January 1,2005 through December 30,2009,and the clinical findings from close observation were filled into the tables of specially designed “ Clinical observation of acute poisoning patients”.Some risk factors of 356 cases with complete clinical data were studied by single-factor analysis and Logistic multiple regression,such as gender,age,mode and cause of poisoning,kind of poison agents,time elapsed from poisoning to admission into the hospital,time elapsed from poisoning to admission into ICU,length of hospital stay,cardiopulmonary resuscitation,mechanical ventilation,APACHE Ⅱ score.Results Three hundred fifty-six patients with complete data were divided into survival group (n =260) and death group (n =96).Univariate analysis showed the length of hospital stay (5.72 ± 4.37) d,APACHE Ⅱ score (10.27 ±7.77),time elapsed from poisoning to admission into ICU (17.16 ± 31.22)h in the survival group,and the length of hospital stay (3.53 ± 5.79) d,APACHE Ⅱ score (18.78 ±8.66),time elapsed from poisoning to admission into the ICU (37.21 ±67.35) h in the death group (P ＜0.05 or P ＜ 0.01).The differences in rates of CPR,mechanical ventilation and kind of poison agents between the two groups were statistically significant (P ＜ 0.05).Multivariate Logistic regression analysis revealed that the length of hospital stay,APACHE Ⅱ score,rates of cardiopulmonary resuscitation,mechanical ventilation and kind of poison agents were positively correlated with prognosis of patients with acute poisoning (P ＜ 0.05).Model to predict mortality was established:Y =-0.817-0.137X1 +0.140X3 + 2.133X4 + 1.039X5-0.291X6.Conclusions Hospital stay,APACHE Ⅱ score,cardiopulmonary resuscitation,mechanical ventilation and kind of poison agents were independent risk factors for predicting prognosis.APACHE Ⅱ score system and Logistic regression analysis can be used to evaluate the severity and prognosis of patients with acute poisoning.
