Clinical Analysis Of 36 Cases Of Pernicious Placenta Previa

Objective: To investigate the risk factors, diagnosis, expectanttreatment, surgical management, Maternal outcomes and neonatal outcome of pernicious placenta previa.Methods: The data of 165 cases of patients with pernicious placenta previa that gave birth in our hospital from January 2011 to December 2014 was retrospectively analyzed. 165 patients with placenta previa included 36 patients with pernicious placenta previa and 129 patients with non pernicious placenta previa. Statistical analysis was performed with Mann-Whitney U test and Chi-square test. All analyses were adjusted for the confounding effects of the general information, surgical management data, Maternal outcomes and neonatal outcome.Results: 1. Complete placenta previa patients in the observation group proportion was significantly higher than that of the control group, non proportion of complete placenta previa in observation group was significantly lower than that of the control group, compare the differences between the two groups have statistical significance(c2=10.942,P<0.05). 2.There were significant differences in the frequency of pregnancy, cesarean frequency is more than 2 times, artificial abortion, gestational age, placenta accrete rate,blood transfusion, postpartum hemorrhage, hysterectomy, operation time, bleeding volume, premature delivery, neonatal birth weight between two groups(P<0.05). 3.There were significant differences in the age, maternal Advanced age and Apgar score between two groups(P>0.05).Conclusion: 1.For more than 3 times of pregnancy, cesarean section is more than 2 times, with a history of abortion with dangerous placenta previa is wary of placenta implantation.2. Dangerous placenta previa had a higher incidence of preterm birth and rate of hysterectomy. The early use of ultrasound and MRI to make the correct diagnosis is very important to choose effective treatmentmeasures. 3. To fully understand the patient’s condition, comprehensive consideration of the mother and fetus to develop individual appropriate treatment programs.To determine the correct delivery time. Adequate preoperative preparation, peri operation period of favorable measures in a timely manner, to the control of hemorrhage. The standard treatment and the correct choice of delivery time can improve the pernicious placenta previa maternal and perinatal outcomes.
