Related factors and bacteriological analysis of puerperal infection in pregnant women with scarred uterus / 国际检验医学杂志

ABSTRACT

Objective To investigate the risk factors and etiology of puerperal infection in pregnant women with scar uterus.Methods 276 cases of uterine scar pregnant women were prospectively collected in the hos-pital,according to the development of postpartum puerperal infection or not,all pregnant women were divided into an infection group(n=25)or a non infection group(control group)(n=251).The main clinical features between the two groups were compared and the risk factors of puerperal infection in pregnant women with u-terine scar were analyzed.Results Compared with the control group,the incidence of gestational <37 weeks, perilous placenta previa,postpartum hemorrhage,premature rupture of membranes,placental abruption,preg-nancy induced hypertension and the past history of vaginitis was significantly higher in the infection group,and the difference was statistically significant(P< 0.05).Multivariate logistics regression analysis showed that the risk factors of puerperal infection in pregnant women with scarred uterus included dangerous placenta pre-via,postpartum hemorrhage and placental abruption.Gram negative bacteria were more common,accounting for 72.00%,the most common gram negative bacteria were Escherichia coli(32.00%),the most common gram positive bacteria were Staphylococcus aureus(12.00%).Conclusion Dangerous placenta previa,post-partum hemorrhage and placental abruption are the risk factors of puerperal infection in pregnant women with uterine scar,and Gram negative bacteria are common pathogens.
