新生儿窒息常合并心脑等多系统损害，本文通过检测血清ＣＫ－ＭＢ（心型）和心电图，评价心肌损害情况。３６例窒息新生儿，轻度窒息１５例，重度窒息２１例，分别于治疗前、治疗７天后测ＣＫ－ＭＢ、心电图，治疗前轻度组ＣＫ－ＭＢ水平为３１．５±１５．４、异常率４６．７％，重度组分别为５０．５±２０．３、８５．７％，两者有显著性差异（Ｐ＜０．０５），治疗后ＣＫ－ＭＢ水平及异常率明显下降（Ｐ＜００５），治疗前心电图仅５例异常，治疗后完全恢复。随诊１～４月无ＣＫ－ＭＢ及心电图异常，结果提示，特异性心肌酶（ＣＫ－ＭＢ）是反映窒息新生儿心肌损害的一个敏感指标，心电图可反映心肌损害，但敏感性较低。观察和随诊说明心肌损害恢复较快，预后良好。
Neonatal asphyxia often combined with heart and brain damage and other systems, this paper by detecting serum CK-MB (cardiogram) and electrocardiogram, evaluation of myocardial damage. 36 cases of asphyxia, 15 cases of mild asphyxia and 21 cases of severe asphyxia. CK-MB and ECG were measured before treatment and 7 days after treatment respectively. The level of CK-MB in mild group before treatment was 31.5 ± 15.4, The abnormal rate was 46.7% in the severe group and 50.5 ± 20.3 and 85.7% in the severe group (P <0.05), and the CK-MB level and abnormal rate were significantly decreased after treatment P <0 05), before treatment ECG abnormalities in only 5 cases, completely recovered after treatment. There was no CK-MB and ECG abnormalities in follow-up from January to April. The results suggested that CK-MB was a sensitive indicator of myocardial damage in neonates with asphyxia. ECG could reflect myocardial damage, but the sensitivity was low. Observation and follow-up showed that myocardial damage recovered faster and the prognosis was good.
