Objective To investigate the effect of therapeutic effects and recovery by serum thermal decomposition method in the treatment of elderly patients with sequela of cerebral infarction.Methods49 cases patients with cerebral infarction in our hospital were selected and randomly divided into the control group and the experiment group.23 cases in the control group were treated by conventional therapy.26 cases in the experiment group were treated on the base of the control group with serum thermal decomposition method.10 days a course of treatment, after 2 courses, the clinical efficacy and recovery of patients in the two groups were compared.ResultsThe total effective rate of the experimental group was 92.3% higher than that of the control group (65.2%), and the difference was statistically significant (P<0.05).Two groups of patients with neurological impairment score and the National Institutes of Health Stroke Scale (NIHSS) score were reduced.Compared with the control group, the neurological impairment score and NIHSS score of the experimental group were lower, the difference was statistically significant(P<0.05).The experiment group motor function (Fugl-Mayer) score was higher, the difference was statistically significant (P<0.05);the experiment group quality of life score was higher, the difference was statistically significant (P<0.05).ConclusionThe method of serum pyrolysis poisoning treatment of elderly patients with cerebral infarction sequelae can significantly reduce the degree of neurological impairment, improve patient quality of life and sequelae recovery.
