ObjectiveTo explore the related factors for the influences and outcomes of mothers and infants, and further provide a basic reference for reducing maternal and prenatal mortality caused by central placenta previa, through the analysis of its clinical characteristics. MethodsWe retrospectively analyzed the clinical data of 89 patients with central placenta previa treated from January to August 2012. ResultsThere were 89 patients with central placenta previa, and the average age of these patients was (29.6±11.4) years, and the average number of pregnancy among the patients was 3.17. Nine patients had scar uterus; 8 had pernicious placenta previa (9%); 34 had prenatal anemia symptoms; 44 had prenatal vaginal bleeding with the bleeding volume ranged from 2 to 500 mL; 40 were treated before delivery. The average gestational age was 36 weeks ±4.2 days, and 28 of them were readmitted. The intraoperative bleeding in such patients as had placenta located in the anterior wall, placenta adhesion or implantation, history of uterine cavity operation or multipara was more than other patients. The postpartum hemorrhage of patients with the gestational age of 36 weeks or more was more than that of patients with the gestational age shorter than 36 weeks. The incidence of fetal distress in patients with the gestational age of 36 weeks or more is lower and the neonatal 1-minute Apgar score was higher than that in patients with the gestational age shorter than 36 weeks (P<0.05). ConclusionThe treatment of central type of placenta previa should be more active to prolong the gestational week. Patients with placenta adhesion or implantation, caesarean, multipara and placenta in the anterior wall are susceptible to intraoperative bleeding during the termination of pregnancy. Termination of pregnancy in these patients with central placenta previa should be carried out by cesarean section when gestation is more than 36 weeks to reduce postpartum hemorrhage and complications.
目的探讨妊娠期体外循环手术的围术期处理方法及母婴安全性。 方法回顾性分析2006年1月至2014年3月福建省立医院心外科21例妊娠期行体外循环手术患者的临床资料，年龄（26.2±3.4）岁。 结果母亲19例生存，2例死于多器官功能衰竭。婴儿6例引产，2例死亡，生存13例。随访13例存活新生儿8个月至8年，并对4例年龄大于6岁的儿童进行韦氏儿童智力量表第4版（WISC-IV）测试，得分分别为92分、104分、106分、90分，平均98分，与正常儿童无明显差异[（100±15）分]。 结论体外循环下心脏手术对于妊娠期合并严重心脏病患者是可行的，手术的危险性主要取决于手术方式、手术时间、孕周、体外转流时间、是否深低温等，应采取多学科合作，根据患者具体情况制定个体化方案。
