目的:探讨前置胎盘妊娠结局变化,提高前置胎盘对孕产妇危害性的认识。方法:回顾性分析148例前置胎盘病例(病例组)与112例随机抽取的单胎产妇(对照组)的临床资料,同时将病例组分为中央型、部分型和边缘型前置胎盘进行组内比较。结果:病例组产前贫血、胎盘粘连、胎盘植入、产后出血、子宫切除、手术时间、住院时间均大于对照组(P<0.05)。不同类型前置胎盘患者在妊娠结局项目类型上存在统计学差异(P<0.05),中央型产前贫血、手术时间超过40 min、胎盘植入、产后出血、子宫切除的比例高于边缘型和部分型,其差异均有统计学意义(P<0.05)。中央型和部分型患者住院>7天的比例接近60%,高于边缘型胎盘前置的比例(P<0.05)。结论:应高度重视前置胎盘尤其是中央性前置胎盘,预防是关键。
Objective: To investigate the change of pregnancy outcome of placenta previa and to raise the awareness of placenta previa on maternal risk. Methods: The clinical data of 148 cases of placenta previa (case group) and 112 cases of single fetus (control group) were retrospectively analyzed. At the same time, the cases were divided into central, partial and marginal placenta previa Group comparison. Results: Prenatal anemia, placenta accreta, placenta accreta, postpartum hemorrhage, hysterectomy, operation time and hospital stay were all higher in the case group than in the control group (P <0.05). Patients with different types of placenta previa had statistically significant differences in pregnancy outcome (P <0.05), central prenatal anemia, operation time longer than 40 min, placenta accreta, postpartum hemorrhage, and hysterectomy were higher than those in borderline Some types, the differences were statistically significant (P <0.05). Central and partial patients were hospitalized for> 7 days at a rate of nearly 60%, which was higher than that of marginal placenta previa (P <0.05). Conclusion: Placenta previa should pay great attention, especially the central placenta previa, prevention is the key.
