Abstract:
Objective To compare the efficacy and safety of different courses of caffeine citrate injection in the treatment of very low birth weight infants.Methods Very low birth weight infants were divided into long course group and routine course according to cohort method.2 groups of children were given intravenous infusion of caffeine citrate injection loading dose(20 mg·kg-1)within 3 days after birth,and the dose was maintained at 5 mg·kg-1 after 24 hours(qd).In the long course group,caffeine citrate injection was used to correct gestational age＞34 weeks,and in the routine course,caffeine citrate injection was used to correct gestational age 33-34 weeks.The use of caffeine citrate injection,clinical efficacy,neonatal behavioral neurological scale(NBNA)score and the occurrence of adverse drug reactions were compared between the two groups.Results 116 cases were included in this study,64 cases in the long course group and 52 cases in the routine course.After treatment,the total clinical effective rate of the long course group and the routine course was 92.19％and 94.23％,respectively,with no statistical significance(P＞0.05).The total duration of caffeine citrate injection were(60.53±8.92)and(48.17±5.24)days,respectively;the corrected gestational age at withdrawal were(36.02±1.56)and(33.18±1.27)weeks,respectively.The corrected gestational age were(34.31±0.48)and(32.06±0.51)weeks;the milk volume were(32.69±2.14)and(23.85±1.69)mL,respectively,with statistical significance(all P＜0.05).The starting age of caffeine citrate injection were(59.65±3.42)and(58.35±3.11)h in the long course group and the routine course,respectively,with no statistical significance(P＞0.05).Before treatment,the NBNA score of the long course and routine courses were 36.49±6.78 and 35.58±4.22,respectively;the NBNA score of long course and conventional course after treatment were 43.25±6.88 and 44.12±7.42,respectively.Compared with before treatment,NBNA score in both groups were higher after treatment,with statistical significance(all P＜0.05).There was no significant difference in NBNA score between the long course group and the routine course(P＞0.05).The incidence of bronchopulmonary dysplasia(84.38％vs 51.92％)and decreased hemoglobin concentration(17.75％vs 5.77％)in the long course group were significantly higher than those in the routine course(all P＜0.05).Conclusion Long-term use of caffeine citrate injection to correct gestational age＞34 weeks has no significant effect on clinical treatment,neurological function and intellectual development of very low birth weight infants.
