Analysis Of Pregnancy Outcome Of 185 Patients With Pernicious Placenta Previa

Objective: to explore the clinical characteristics,high risk factors,the final outcome of different treatment regimens and the analysis of the effects of pregnancy and pregnancy.Methods: from January 2015 to March 2017,185 patients in the first affiliated hospital of xinjiang medical university were confirmed as the patients with dangerous preplacental placenta by prenatal doppler color ultrasonogrAPhy and previous history.Retrospective analysis of pregnancy outcomes under different pregnancy conditions in the case.Results:1)the sensitivity(true positive rate)of b-ultrasonogrAPhy to the diagnosis of dangerous placental placenta was 59.8%,and its specificity(true negative rate)was: 70.5%;2)for the diagnosis of placenta previa dangerous sex is divided into two groups,did not place the abdominal aorta ball placed abdominal aorta with balloon group,for the pregnancy outcomes of intraoperative blood loss,intraoperative blood transfusion rate,uterus resection and postoperative rate of transferred to the intensive care unit,two groups were compared,the difference had statistical significance(P<0.05);3)high factors of placenta previa for disaster statistics,the use of logistics regression method,the result of maternal pregnancy number and number of cesarean delivery has effects on the pregnancy outcome of statistical significance,and again after using multiple factor analysis results statistically significant between them;4)in the case of the dangerous preplacental placenta,the location of placenta in different placenta,the amount of blood loss in the pregnancy outcome was statistically significant;5)for dangerous placenta previa cases,it can be divided into with gestational diabetes and without gestational diabetes in the two groups,the intraoperative blood loss,placenta implantation,uterus resection rate and maternal mortality has no statistical significance;6)for dangerous placenta previa cases,it can be divided into with gestational hypertension disease and no gestational hypertension disease of two groups,the intraoperative blood loss,placenta implantation,uterus resection rate and maternal mortality has no statistical significance.Conclusion: in recent years,the incidence of placenta previa dangerous sex rise year by year,mainly by color dopplerultrasound diagnosis,the placenta is given priority to with anterior wall of the uterus,clinical risk is extremely high,maternal pregnancy time 4 or more time and production time is 2 or more times for the dangerous sex of placenta previa merged into high-risk factors,compared with the previous process is an effective method of placenta increta hysterectomy,the radical of the surgery,now before placed abdominal aortic balloon,the results show that the intraoperative blood loss,intraoperative blood transfusion rate and improved significantly reduced the incidence of hysterectomy.
