Abstract：Objective To explore the related factors and etiological structure of puerperal infection, and to provide evidence-based evidence for the prevention and control of puerperal infection.Methods The clinical data of 105 cases of puerperal infection in Foshan Gaoming Hospital Affiliated to Guangdong Medical University from January 2017 to December 2019 were retrospectively analyzed, and they were set as the study group, and 100 cases of normal pregnant women in the same period were randomly selected as the control group.The factors of puerperal infection were analyzed, bacteriological detection was carried out on puerperal infection patients and the pathogenic structure was analyzed.Results The results of univariate analysis showed that there were significant differences between the study group and the control group in the aspects of age, antenatal hemoglobin, antenatal genital tract secretion, second stage of labor, perinatal complications, postpartum hemorrhage and delivery mode, blood transfusion (P＜0.05).Multivariate Logistic regression analysis showed that moderate prenatal anemia, infection of reproductive tract, prolonged second stage of labor and perinatal complications were independent risk factors of puerperal infection (P＜0.05).The results of bacteriological culture showed that Gram-negative bacteria accounted for 72.5%, Escherichia coli, Klebsiella pneumoniae and Gardnerella vaginalis ranked the top three.Gram-positive bacteria accounted for 27.5%, Staphylococcus aureus, Enterococcus faecalis and Staphylococcus epidermidis ranked the top three.Conclusion Correcting prenatal anemia, preventing reproductive tract inflammation, controlling the second stage of labor and other factors may be effective in preventing puerperal infection; Gram-negative bacteria are important pathogens of puerperal infection.
