摘要: 目的 探讨出生后早期给予大剂量促红细胞生成素(erythropoietin,EPO)对极低体重早产儿脑发育的保护作用,为临床提供参考。 方法 选取2017年1—11月出生后入住温州市中心医院新生儿科的60名极低体重早产儿,采用随机数字表法分为治疗组和对照组。治疗组接受rhu-EPO剂量为1 000 U/kg,1次/d,共3 d,对照组不给予rhu-EPO治疗,其他早产儿常规处理与治疗组相同;在纠正胎龄40周行新生儿神经行为测定,在纠正月龄6个月和纠正月龄12个月时用Gesell量表进行神经功能评估,在纠正胎龄40周、纠正月龄6个月和纠正月龄12个月行ABR检查。 结果 治疗组输血比例低于对照组(43.3%vs. 70.0%),差异具有统计学意义(χ2=4.343,P=0.037);纠正胎龄40周时治疗组NBNA评分优于对照组[(35.6±2.1)分vs.(34.3±1.9)分,P=0.017];Gesell发育量表评估结果显示,在纠正月龄6个月时治疗组在大运动(68.7±4.3 vs. 66.5±3.6)、适应能力(63.8±5.3 vs. 61.2±4.3)方面优于对照组(P=0.036、0.041);纠正月龄12个月时治疗组在大运动(103.1±5.9 vs. 99.1±4.7)、精细运动(101.5±5.1 vs. 98.6±5.3)及语言(98.4±5.3 vs. 96.1±3.2)方面优于对照组(P=0.005、0.035、0.046)。 结论 出生后早期使用大剂量EPO对极低出生体重早产儿是有益的,可改善脑发育的预后。Abstract: Objective To investigate the protective effects of high dose EPO on the brain development of very low birth weight preterm infants in early postnatal period, and to provide reference for clinical practice. Methods Sixty very low-weight preterm infants from the Department of Neonatology, Wenzhou Central Hospital were selected from January 2017 to November 2017, who were randomly divided into treatment group and control group. The treatment group received 1 000 U/kg rhu-EPO once a day for 3 days, the control group was not given rhu-EPO treatment, and the routine treatment of other premature infants was the same as that of the treatment group. The neonatal neurological behavior was measured at 40 weeks of corrected gestational age, the neurological function was evaluated with Gesell scale at 6 months and 12 months of corrected gestational age, and ABR was examined at 40 weeks, 6 months and 12 months of corrected gestational age. Results The blood transfusion rate of the treatment group was lower than that of the control group(43.33% vs. 70.00%), and the difference was statistically significant(χ2=4.343, P=0.037). The NBNA score of the treatment group was better than that of the control group(35.6±2.1 vs. 34.3±1.9) when the gestational age was 40 weeks(P=0.017). The Gesell scale assessment showed that the treatment group was superior to the control group in the large exercise(68.7±4.3 vs. 66.5±3.6) and adaptability(63.8±5.3 vs. 61.2±4.3) at 6 months of corrected gestational age(P=0.036, 0.041). The treatment group was superior to the control group in terms of large exercise(103.1±5.9 vs. 99.1±4.7), fine motor(101.5±5.1 vs. 98.6±5.3), and language(98.4±5.3 vs. 96.1±3.2)(P=0.005, 0.035, 0.046) at 12 months of corrected gestational age. Conclusion Early use of high-dose EPO is beneficial for very low birth weight premature infants and can improve the prognosis of brain development.
