  • 摘要:
  • 目的 探讨促红细胞生成素(EPO)联合亚低温治疗中重度新生儿缺氧缺血性脑病(NHIE)的疗效。方法 选取20173月至20197月于甘肃省妇幼保健院住院治疗的92例中重度NHIE患儿,根据随机数字表法分为观察组和对照组,各46例。所有患儿均接受亚低温治疗72 h,观察组予重组人促红素注射液静脉滴注,对照组予0.9%氯化钠注射液静脉滴注,均治疗14 d。记录2组基线资料,比较2组出生后2472168 h血清超氧化物歧化酶(SOD)水平。治疗14 d后行头颅磁共振成像(MRI)检查,计算并比较2组改良的Barkovich评分。结果 2组胎龄、体质量、男性比例、1 min Apgar评分、惊厥比例、自然分娩比例比较,差异均无统计学意义(均P0.05)。观察组出生后2472168 h 血清SOD水平逐渐降低[(232±141)、(174±84)、(124±28kU/L],且观察组出生后72168 h 血清SOD水平均低于对照组[(247±103)、(189±66kU/L],差异均有统计学意义(t=3.7086.153,均P0.001)。治疗14 d后观察组18例、对照组21例患儿头颅MRI异常。头颅MRI异常患儿中,观察组改良的Barkovich评分低于对照组[(2.0±1.3)分比(4.0±1.7)分],差异有统计学意义(t=4.014P0.001)。结论 EPO联合亚低温治疗中重度NHIE能进一步减轻神经系统损伤,改善预后。

  • Objective To investigate the curative efficacy of erythropoietin combined with mild hypothermia therapy on moderate and severe neonatal hypoxic-ischemic encephalopathy(NHIE). Methods From March 2017 to July 2019, 92 neonatus with moderate and severe NHIE hospitalized in Gansu Provincial Maternity and Child-care Hospital were enrolled. They were randomly divided into observation group and control group, with 46 cases in each group. All neonatus were given mild hypothermia therapy for 72 h. The observation group was given recombinant human erythropoietin injection for intravenous infusion, and the control group was given 0.9% sodium chloride injection for intravenous infusion. Both groups were treated for 14 d. The baseline data of the two groups were recorded. Levels of serum superoxide dismutase(SOD) at 24, 72 and 168 h after birth were compared between the two groups. After 14 d of treatment, the cranial magnetic resonance imaging (MRI) was finished, and modified Barkovich score was calculated and compared between the two groups. Results There were no significant differences in gestational age, body mass, male rate, 1 min Apgar score, convulsions rate and spontaneous delivery rate(all P>0.05). The serum SOD level in the observation group gradually decreased at 24, 72 and 168 h after birth[(232±141,174±84,124±28kU/L, and that in the observation group at 72 and 168 h was lower than that in the control group[(247±103,189±66kU/L(t=3.708, 6.153, both P<0.001). After 14 d of treatment, there were 18 cases with abnormal cranial MRI in the observation group and 21 cases with that in the control group. Among those abnormal cranial MRI cases, the modified Barkovich score in the observation group was lower than that in the control group[(2.0±1.3 vs 4.0±1.7)](t=4.014 P0.001. Conclusion Erythropoietin combined with mild hypothermia therapy in moderate and severe NHIE can further reduce the nervous system injury and improve prognosis.
