Abstract:

Objective To investigate the related influencing factors of Mycoplasma pneumoniae pneumonia(MPP) complicated with myocardial damage. Methods A total of 126 children diagnosed with MPP in the Department of Pediatrics of Weifang Maternal and Child Health Care Hospital from January 2018 to January 2020 were selected as the research subjects.According to whether they were complicated with myocardial injury，they were divided into observation group(MPP complicated with myocardial injury，66 cases) and control group(without complication with myocardial injury，60 cases).The general data of the subjects were collected，and the heat duration，heat peak，chest X-ray results，length of hospital stay，and age of onset were observed to learn about the main influencing factors of myocardial damage in children with MPP.Results (1) Univariate analysis showed that the difference in 5 factors was statistically significant (P<0.05):the heat course was >5 days，the heat peak was >39 ℃，the chest film showed lobar pneumonia，the hospital stay was >10 days，and the onset age was <2 years.(2)Logistic regression analysis showed that heat duration >5 days，lobular pneumonia on chest radiograph and onset age <2 years were the main risk factors for MPP complicated with myocardial damage.Conclusion For children with Mycoplasma pneumoniae pneumonia，if fever lasts more than 5 days，chest radiograph indicates lobar pneumonia，and the onset age is less than 2 years，the possibility of being complicated with myocardial damage should be considered.For patients at high risk of MPP complicated with myocardial damage，it is necessary to strengthen management，complete the necessary examinations such as electrocardiography and cardiac color ultrasonography，and actively intervene to improve the prognosis of MPP children.
