心电图异常早产儿的围产期危险因素分析

Analysis on the perinatal risk factors in premature infants with abnormal electrocardiogram

目的:探讨心电图异常早产儿的相关围产期危险因素。方法:采用回顾性分析法,对82例发生心电图异常及37例未发生心电图异常的早产儿进行相关因素分析,二元logistic回归模型分析法进行危险因素分析。结果:胎膜早破时间≥18 h、妊娠高血压病及绒毛膜羊膜炎、窒息是早产儿发生心电图异常的危险因素(P<0.05);而出生时高体质量是早产儿发生心电图异常的保护因素(P<0.05)。结论:围产期多种因素是早产儿出生后发生心电图异常的危险因素,对有危险因素的低出生体质量早产儿应做好心电图动态监测。

Objective:To investigate the perinatal risk factors of premature infants with abnormal electrocardiogram(ECG).Methods:The related factors were reviewed in 82 premature infants with abnormal ECG and 37 with normal ECG.Binary logistic regression model was used to analyze the risk factors.Results:The risk factors for premature infants with abnormal ECG were associated with premature rupture of membranes≥18h,pregnancy-induced hypertension syndrome,chorioamnionitis and asphyxia(P<0.05),whereas a large body mass at birth was the protective factors for preterm infants.Conclusion:Multiple factors in perinatal period can result in risks for premature infants with abnormal EKG after birth.Therefore,dynamic electrocardiogram monitoring is necessary for premature infants of low birth weight associated with the risks described above.
