Objective To explore the effect of single blood perfusion combined with blood perfusion combined with continuous venous venous blood filtration (sequential blood purification) on myocardial injury in patients with severe acute organophosphorus pesticide poisoning.MethodsRetrospectively analyzed in July 2013 to July 2015 treated in our hospital see a doctor and a total of 94 patients with severe acute organophosphorus pesticide poisoning, depending on the patient's blood purification scheme, divided the patients into blood perfusion group (n=48) and sequential blood purification group (n=46), contrast after treatment on two groups of clinical curative effect, the condition of myocardial spectrum index and its complications.ResultsAfter treatment, blood perfusion group of left ventricular ejection fraction was (53.8±5.8)%, sequential left ventricular ejection fraction after blood purification treatment group was (58.1±3.4)%, both have obvious difference, has statistics meaning (P<0.05).In terms of myocardial enzyme spectrum index, and sequential blood purification group is obviously better than the index of myocardial enzymes in patients with blood perfusion group (P<0.05).The incidence of complications in patients with sequential blood purification group were lower than the blood perfusion group (P<0.05).ConclusionThe joint continuity venous blood perfusion-blood purification scheme of vein hemofiltration treatment of patients with severe acute organophosphorus pesticide poisoning can significantly improve treatment effect.
