Abstract：Objective:To study the relationship between cervical mycoplasma infection and hemorrhage in cesarean section among patients with placenta previa.Method:25 cases of pregnant week>28 weeks,placenta bleeding patients were selected,B ultrasound description of the placental edge from the cervix,blood pool,sponge like echo,hospitalized patients with mycoplasma culture+drug sensitivity test,25 patients were followed up to the end of cesarean section.Result:All of 5 cases with increased number of placental lacunas and 13 cases(65%) of the 20 cases without increased number of placental lacunas have experienced uterine lower segment bleeding during cesarean section[(P=0.11,OR=1.53,95%CI(1.11,2.12)].A positive correlation was determined between cervical mycoplasma colonization and the existence of placental lacunas on ultrasonography(r=0.408).A positive correlation was determined between cervical mycoplasma colonization and uterine lower segment bleeding during cesarean section[r=0.145,P=0.48;OR=1.20;95%CI(0.74,1.92)]. 9 cases(56%) of 16 cases who were diagnosed as placenta previa totalis and 1 case(11%) of 9 cases who were diagnosed as placenta previa partialis and/or marginalis had positive cervical culture results for mycoplasma colonisation that revealed a positive correlation between placenta previa totalis and cervical mycoplasma colonization[r=0.442,P=0.02;OR=5.06;95%CI(0.75,33.77)].Conclusion:Cervical colonization of mycoplasma as a marker of endometritis in pregnancies complicated with placenta previa that can predict the lower uterine segment bleeding risk during cesarean section.
