中文摘要:
      目的 分析急性百草枯(Paraquat,PQ)中毒患者的死亡独立危险因素,为PQ 中毒的急诊治疗及预后评估提供临床依据。方法 回顾性分析2016 年1 月至2019 年12 月期间我院收治的、年龄>12 岁、中毒时间<24 h的PQ 中毒患者的95例临床资料。按照1 个月后的结局分为死亡组53例和存活组42例;对比两组患者入院时的基本情况、检验指标、血液净化治疗等临床资料;应用Logistic 回归分析PQ 中毒死亡的独立危险因素,并绘制受试者工作特征曲线,评价各危险因素对预后评估的准确性。结果 服毒量、启动血液净化时间、血乳酸为PQ 中毒患者死亡的独立危险因素;服毒量>58.5 mL、启动血液净化时间>5.5 h、血乳酸>5.95 mmol/L 的PQ 中毒患者死亡风险明显升高;对PQ 的死亡预测能力从高至低依次为:血乳酸、启动血液净化时间、服毒量。结论 在临床工作中必须尽早对PQ 中毒患者实施血液净化治疗,迅速、有效降低体内的PQ 浓度,有助于提高PQ 中毒患者的存活率;同时结合服毒量及血乳酸水平可作为预测PQ 中毒患者死亡的可靠性指标。
英文摘要:
      Objective To analyze independent risk factors for death in patients with acute paraquat (PQ) poisoning,and to provide clinical evidence for emergency treatment and prognosis evaluation of PQ poisoning.Methods The clinical data of 95 patients with PQ poisoning admitted to our hospital from January,2016 to December,2019,who were older than 12 years old and had been poisoned for less than 24 hours were retrospectively analyzed.According to the outcome after one month,they were divided into 53 cases in the death group and 42 cases in the survival group.The basic conditions,test indicators,and blood purification treatment of the two groups at the time of admission were compared.Logistic regression was used to analyze the independent risk factors of death from PQ poisoning.And the receiver operating characteristic curve was drawn.The accuracy of the prognostic evaluation of each risk factor was evaluated.Results The dose of poison,the time to start blood purification,and blood lactic acid were independent risk factors for death in PQ poisoned patients.The risk of death was significantly increased in PQ poisoned patients with the dose of poison more than 58.5 mL,the time to start blood purification more than 5.5 h,and the blood lactic acid more than 5.95 mmol/L.The predictive ability of PQ's death from high to low was blood lactic acid,time to start blood purification,and dose of poison.Conclusion In clinical work,it is necessary to implement blood purification treatment for patients with PQ poisoning as soon as possible to quickly and effectively reduce the PQ concentration in the body,which will help to improve the survival rate of patients with PQ poisoning.At the same time,combining the dose and blood lactic acid level can be used as a reliable predictor of death in patients with PQ poisoning.
