Abstract:〔Abstract〕 Objective To evaluate the application value of naloxone hydrochloride in the treatment of cerebral infarction. Methods A total of 86 patients with cerebral infarction who were treated in Nanyang First People's Hospital from April 2019 to March 2020 were selected and randomly divided into observation group (43 cases) and control group (43 cases). All patients received basic treatment after admission, and patients in the control group were treated with Naoxintong capsules orally. Patients in the observation group received naloxone hydrochloride treatment in addition to the treatment in the control group. The improvement effect of neurological deficits and the safety of medication were compared between the two groups. Results Before treatment, there was no significant difference in the scores of the national institutes of health stroke scale (NIHSS) between the two groups of patients (P > 0.05); After treatment, the NIHSS scores of the observation group were lower than those of the control group, and the difference was statistically significant (P < 0.05). The total clinical effective rate of the observation group was significantly higher than that of the control group, and the difference was statistically significant (P < 0.05). There was no statistically significant difference in the incidence of adverse reactions between the two groups of patients (P > 0.05). Conclusion Providing naloxone hydrochloride treatment for patients with cerebral infarction can promote the improvement of neurological deficits, improve the therapeutic effect, and have high application safety
