Analysis of clinical characteristics and prognosis risk factors for acute dichlorvos poisoning
Objective To describe the clinical characteristics of acute dichlorvos poisoning and analyzed the risk factors affecting patient prognosis,in order to provide important treatment guidance and theoretical reference for reducing the mortality of patients with acute dichlorvos poisoning.Methods A retrospective study method was conduct to collect the clinical data of patients admitted to the department of emergency of Fuyang People's Hospital from November 2019 to November 2023 and analyze the clinical poisoning characteristics.The patients were divided into death group and survival group according to the prognosis to compare the differences in the clinical characteristics of patients with different outcomes.This study conducted binary multifactor Logistic regression analysis of statistically significant indicators to select the independent risk factors affecting the prognosis of patients,and drew the receiver operator characteristic(ROC)curve to predict value of the risk factors on the prognosis.Results In 82 patients,22(26.83%)died,39(47.56%)developed capillary leak syndrome(CLS),31(37.80%)had acute respiratory failure,and 35(42.68%)had shock.Compared with the survival group,patients in the death group were older(years:57.73±17.67 vs.44.25±13.74),the proportion of gastric lavage,cholinesterase activity,Glasgow coma scale(GCS),albumin,pH value were all significantly decreased[proportion of gastric lavage:81.82%(18/22)vs.100.00%(60/60),cholinesterase activity(U/L):235.96(200.00,401.67)vs.450.00(240.26,739.25),GCS scores:4.00(3.00,6.00)vs.12.00(4.00,15.00),albumin(g/L):39.35±12.02 vs.45.21±4.51,pH value:7.14(7.04,7.26)vs.7.38(7.28,7.40)],dichlorvos concentration,dipterex concentration,sequential organ failure assessment(SOFA),acute physiology and chronic health evaluationⅡ(APACHEⅡ),alanine transaminase(ALT),blood urea nitrogen(BUN),serum creatinine(SCr),MB isoenzyme of creatine kinase(CK-MB),blood lactate acid(Lac),and concurrent acute respiratory failure,shock,CLS ratio were significantly increased[dichlorvos concentration(μg/L):271.00(49.25,908.25)vs.64.00(16.75,211.00),dipterex concentration(μg/L):1 337.50(397.25,3 614.00)vs.494.00(71.00,1 679.80),SOFA score:12.50(9.00,15.50)vs.2.00(0.00,6.75),APACHEⅡscore:28.50(23.00,32.50)vs.6.50(2.25,19.00),ALT(U/L):40.40(17.28,66.33)vs.19.65(13.70,34.68),BUN(mmol/L):6.30±2.78 vs.5.05±1.48,SCr(μmol/L):87.59±39.67 vs.58.87±14.85,CK-MB(U/L):164.80(86.13,284.85)vs.116.05(81.65,160.60),Lac(mmol/L):3.00(1.68,9.15)vs.1.20(1.00,2.40),the proportion of concurrent acute respiratory failure:95.45%(21/22)vs.33.33%(20/60),proportion of concurrent shock:100.00%(22/22)vs.21.67%(13/60),proportion of concurrent CLS:95.45%(21/22)vs.30.00%(18/60)],the differences were statistically significant(all P<0.05).The binary multivariate Logistic regression analysis showed that age,SOFA score,and CLS were independent risk factors affecting the prognosis of dichlorvos poisoning[age:odds ratio(OR)=1.090,95%credibility interval(95%CI)was 1.019-1.167;SOFA score:OR=1.454,95%CI was 1.159-1.825;CLS:OR=122.473,95%CI was 7.954-1 885.787,all P<0.05].The ROC curve analysis shows that the age,SOFA score and CLS had a certain predictive value for the prognosis of patients with acute dichlorvos poisoning[area under the curve(AUC)were 0.752,0.864,0.827,95%CI were 0.622-0.881,0.767-0.960,0.735-0.919,the Youden index were 0.453,0.681,0.655,sensitivity were 63.6%,86.4%,95.5%,specific features were 81.7%,81.6%,70.0%,all P<0.05].Conclusions Age,SOFA score,and CLS are independent risk factors affecting the prognosis of patients with acute dichlorvos poisoning.In particular,CLS is the most important risk factor affecting the prognosis of patients.When managing acute dichlorvos poisoning,it is crucial to closely monitor the occurrence of CLS and administer prompt,proactive treatment.
