Objective To observe the prognosis index in acute arsenic trihydride poisoning patients in order to provide references for early clinical treatment. Methods We retrospectively analyzed the clinical data of 20 acute arsenic trihydride poisoning patients treated between July 2010 and January 2014. The patients were divided into death group and survival group according to survival situation 90 days later. The length of time from onset to treatment, urine arsenic concentration, blood routine, hepatic and renal function, electrolyte, myocardial enzyme, arterial blood gas analysis were observed by single factor analysis, and the positive indexes were analyzed by logistic regression analysis to seek the potential influencing factors for survival. Results Compared with the survival group, the length of time from onset to treatment, urine arsenic, serum total bilirubin, creatinine, creatine kinase of the death group were significantly higher (P<0.05), while the value of pH, HCO3-, BE of the survival group were significantly lower (P<0.05). Logistic regression analysis revealed that these indexes remarkably affected patients' survival rate. Conclusion Therapeutic time window, extent of damage of heart, liver, kidney and acid-base imbalance are closely associated with the survival rate of arsenic trihydride poisoning patients, and timely treatment for above factors can be useful for improving prognosis.
