RESUMO
OBJECTIVE:To observe the clinical efficacy and safety of vitamin C with large dose combined with diphosphate in the treatment of myocardial injury after neonatal asphyxia and the effects on creatine kinase isoenzyme (CK-MB) level. METH-ODS:Totally 76 children with myocardial injury after neonatal asphyxia were randomly divided into control group and observation group. Control group was given routine treatment,including oxygen inhalation,sedation,cardiotonic,Danshen injection and ener-gy mixture,etc. Based on the treatment of control group,the observation group was added diphosphate 100-150 mg/(kg·d),iv infu-sion,qd;and vitamin C 250 mg/(kg·d)adding into 10%glucose injection 20 ml,iv infusion,qd. 10 d was a course. The clinical ef-ficacy,cardiac troponin T(cTnI),CK-MB level and incidence of adverse reactions before and after treatment were observed. RE-SULTS:The total effective rate in observation group was significantly higher than control group,with significant difference(P<0.05). After treatment,the cTnI and CK-MB level in 2 groups were significantly lower than before,and observation group was low-er than control group,with significant differences (P<0.05). There were no adverse reactions in 2 groups during the treatment. CONCLUSIONS:Based on the routine treatment,Vitamin C with large dose combined with diphosphate has good efficacy in the treatment of myocardial injury after neonatal asphyxia and can effectively reduce the CK-MB level,with good safety.
