摘要:目的:探究新生儿黄疸与正常足月儿心肌损伤的相关性。方法:选择我科2020年10月至2021年4月所有住院新生儿作为研究对象,按照其是否存在新生儿黄疸分为对照组和观察组,对照组100例为达不到新生儿高胆红素血症诊断的无黄疸新生儿,观察组110例黄疸新生儿,两组新生儿均测定血清总胆红素(TB)、肌酸激酶(CK)、肌酸激酶心肌同工酶(CK-MB)、心肌肌钙蛋白l(cTnl)、血清肌红蛋白(Mb)、脑钠肽(BNP)。比较心电图(Q-T间期、ST-T段改变)、心脏彩超(左室射血分数)的情况,对比两组新生儿上述各项指标。结果:两组患者CK、CK-MB、BNP、左室射血分数、Q-T间期、ST-T段改变率对比均无显著差异(P>0.05),观察组患者TBIL水平显著高于对照组,观察组患者cTnl、Mb水平均显著高于对照组,两组对比具有统计学意义(P<0.05)。结论:新生儿黄疸会对正常足月儿心肌产生损伤危害,损伤可能与血清总胆红素升高有关。

【Abstract】Objective: To explore the correlation between neonatal jaundice and myocardial injury in normal term infants. Methods: All hospitalized newborns from October 2020 to April 2021 in our department were selected as the research objects. They were divided into the control group and the observation group according to whether they had neonatal jaundice. The 100 cases in the control group were regarded as the neonatal high biliary redness. In the non-jaundiced neonates diagnosed by anaemia, there were 110 neonates with jaundice in the observation group. Serum total bilirubin (TB), creatine kinase (CK), and creatine kinase myocardial isoenzyme (CK- MB), cardiac troponin 1 (cTnl), serum myoglobin (Mb), brain natriuretic peptide (BNP). Compare the electrocardiogram (Q-T interval, ST-T segment changes), cardiac color Doppler ultrasound (left ventricular ejection fraction), and compare the above indicators of the two groups of newborns. Results: There was no significant difference in the comparison of CK, CK-MB, BNP, left ventricular ejection fraction, QT interval, ST-T segment change rate between the two groups of patients (P>0.05). The TBIL level of the observation group was significantly higher than that of the control group The cTnl and Mb levels of the observation group were significantly lower than those of the control group, and the comparison between the two groups was statistically significant (P<0.05). Conclusion: Neonatal jaundice can damage the myocardium of normal term infants, and the damage may be related to the increase of serum total bilirubin.

新生儿黄疸是新生儿时期的常见症状之一,其是各种原因导致胆红素在体内堆积而引起的,皮肤、工模等有黄染,严重时可能导致神经受损。大部分患儿可自行消退,少部分需要治疗。新生儿黄疸的主要症状有皮肤、黏膜、巩膜发黄,新生儿食欲不振、不安躁动,体温也可能有所上升。临床上大约有85%的足月儿及绝大多数的早产儿在一周内出现黄疸,其主要是因为新生儿的肝脏功能发育不完善,胆红素代谢异常,血中的胆红素浓度升高而引起的一种疾病,具体可分为生理性黄疸和病理性黄疸。新生儿黄疸可以是新生儿正常发育过程中出现的症状,也可以是某些疾病的表现。新生……
