前置胎盘发生率 0 4 6%~ 1 4 8% [1] 不等 ,其发生率高低与孕产次及宫腔操作次数有关。前置胎盘并发症多 ,早产儿、产后大出血、子宫切除发生率高 ,必须引起医务人员的重视。临床资料 一般情况 :1993年 1月至 2 0 0 0年12月 8年间我院收治住院分娩 12 964例 ,前置胎盘117例 (单胎 114例 ,双胎 3例 ) ,占 0 90 %。其中中央性 4 5例 ,占 38 4 6% ;部分性 32例 ,占 2 7 35 % ;边缘性 4 0例 ,占 34 17%。年龄最大 4 1岁 ,最小 2 1岁 ,平均年龄 2 8岁。前置胎盘 117例中 ,初产妇 82例 ,占 70 0 9% ,经产妇 35例 ,占 2 9 91%。初产妇中有流… 相似文献

我院自1999年1月至2001年12月,用天花粉蛋白注射液(上海金山制药厂生产1.2mg/ml)对7例前置胎盘孕妇引产,5例用肌肉注射,2例羊膜腔内注射。其中4例分别于用药后第七或第八天经阴道顺利分娩,3例于用药后5~6天出现DIC,2例在抢救DIC同时行剖宫产,1例病例在抑制宫缩同时抗DIC治疗,3例转危为安,现报道如下。 相似文献

目的探讨妊娠期高血压疾病并发溶血、肝酶升高及血小板减少(HELLP综合征)终止妊娠的时机和方式对母儿影响。方法对6例HELLP综合征患者的临床资料进行回顾性分析。结果 6例均未出现严重并发症,4例剖宫产术终止妊娠,1例阴道分娩,其中子痫1例,死胎1例。结论 HELLP综合征是重度妊高征的并发症,产妇及围生儿死亡率高。适时终止妊娠是治疗HELLP综合征的主要方法。 相似文献

The prevalence of human papilloma virus (HPV)-16 in patients with cervical cancer,the physical status of HPV-16 in patients with cervical lesions,and the role of HPV-16 integration in cervi-cal carcinogenesis were investigated.HPV genotyping was performed by using PCR approach with the primer GP5+/GP6+ and type-specific primer on biopsy specimens taken operatively from 198 women.Multiple PCR was done to detect physical status of HPV-16 in a series of cervical liquid-based cytology samples and biopsy specimens obtained from different cervical lesions with HPV-16 infection,includ-ing 112 specimens with cervical cancer,151 specimens with CINⅠ,246 specimens with CINⅡ and 120 specimens with CINⅢ.The results showed that there were 112 cervical cancer samples (56.57% of total cervical cancer patients) with HPV-16 infection.The frequency of HPV-16 pure integration was 65.18% (73/112),56.57% (47/120),23.58% (58/246) and 7.95% (12/151) in cervical cancer,CINⅢ,CINⅡand CINⅠ patients respectively.In situ hybridization was performed on some paraffin-embedded sections of CINⅡ,CINⅢ and cervical cancer to verify the physical status of HPV-16 infection.Sig-nificant difference was observed between cervical cancer and CINⅠ,CINⅡ,CINⅢ in the frequency of HPV-16 integration (P<0.01).It is suggested that HPV-16 is the most prevalent type and is associated with cervical cancer.In the case of HPV-16 infection there are close associations between the severity of cervical lesions and the frequency of HPV-16 integration.The application of testing HPV genotyping and physical status based on detection of HC-Ⅱ HPV DNA would be in favor of predicting the progno-sis of cervical precancerosis and enhancing the screening accuracy of cervical cancer. 相似文献
