Abstract:Objective To explore the application effect of comprehensive nursing in clinical nursing of Dexamethasone treatment of pediatric viral myocarditis. Methods From April 2017 to December 2018, 96 cases of outpatients and inpatients in Shenyang Hospital of Traditional Chinese Medicine in Liaoning Province were selected, which met the diagnostic criteria of viral myocarditis. The patients were divided into treatment group and control group by double-blind random number table method, 48 cases in each group. Both groups were given conventional treatment and static point Dexamethasone injection. The control group was given routine nursing measures, the treatment group was given comprehensive nursing measures. Both groups were treated for 14 days, after treatment, clinical efficacy, hospital stay, quality of life, creatine kinase (CK), lactate dehydrogenase (LDH), phosphocreatine kinase isoenzyme (CK-MB) index and complications, and nursing satisfaction of the families of the children were compared. Results the total effective rate of the treatment group was higher than that of the control group, with statistically significant difference (P < 0.05). The length of hospital stay in the treatment group was lower than that in the control group, and the difference was highly statistically significant (P < 0.01). The quality of life score of the treatment group was higher than that of the control group, and the difference was highly statistically significant (P < 0.01). After treatment, CK and LDH were lower in the treatment group than those in the control group, with statistically significant differences (all P < 0.01). The CK-MB in the treatment group was lower than that in the control group, and the difference was statistically significant (P < 0.05). The incidence of complications in the treatment group was lower than that in the control group, with statistically significant difference (P < 0.05). The nursing satisfaction of family members in the treatment group was higher than that in the control group, and the difference was statistically significant (P < 0.05). Conclusion Comprehensive nursing measures in Dexamethasone treatment of pediatric viral myocarditis has a significant effect, can improve the clinical symptoms of children, enhance the quality of life. It is worthy of clinical promotion and application.
