改变产妇体位矫正胎方位170例临床观察

目的 探讨产程中改变产妇体位以矫正胎位的临床效果。方法 选择潜伏期经内诊或B超确诊为枕后位的初产妇170例,随机分成研究组和对照组,各85例。研究组在产程中指导产妇取侧俯卧位,对照组孕妇任意体位。结果 研究组72例(84.71％)胎儿从枕后位转至枕前位经阴道娩出。剖宫产13例,占15.29％,对照组经阴道娩出仅28例,22.94％,剖宫产57例,67.06％。两组比较,P<0.01),差异有非常显著性。两组产程比较,P<0.01,差异有极显著性。结论 在产程中指导产妇取胎儿脊柱侧行同侧侧俯卧位矫正胎头枕后位可降低难产发生率及剖宫产率,有助于提高分娩质量。     

前不均倾位51例临床分析

目的:探讨前不均倾位的诊断及处理方法,以期提高临床医师对前不均倾位的认识。方法:对我院1995年1月~2006年11月收治的51例前不均倾产妇的发病年龄、胎产次、发病原因、临床表现、母儿产时产后并发症及诊治方法进行分析。结果:50例前不均倾均以剖宫产结束分娩、母婴安全。1例自然分娩。结论:前不均倾位产时并发症多,不易做出早期诊断,对母婴危害大,难以经过阴道分娩,诊断一旦明确,应及时行剖宫产终止妊娠。     

旋后肩法处置肩难产对产妇分娩后盆底肌功能改善的临床研究

目的探讨旋后肩法用于肩难产产妇,对其产后盆底肌功能的改善作用。 方法选择2018年7月至2020年1月,在宁波市妇女儿童医院采用旋后肩法完成肩难产助产的28例产妇为研究对象,并纳入研究组。选取同期在本院分娩,采用耻骨联合上加压法完成肩难产助产的25例产妇纳入对照组。采用表面肌电图(sEMG),获取2组产妇分娩8周后盆底肌收缩运动肌电值。采用成组t检验,对2组产妇一般临床资料、盆底sEMG检测结果进行统计学分析。采用χ²检验,对2组产妇分娩巨大儿所占比例等进行统计学分析。本研究遵循的程序符合病例收集医院伦理委员会制定的伦理学标准,得到该委员会批准[审批文号：[2018]伦审字(28)号]。与所有受试者签署临床研究知情同意书。 结果①2组产妇身高、体重,分娩时人体质量指数(BMI)、孕龄、年龄等一般临床资料比较,差异均无统计学意义(P>0.05)。②2组产妇分娩新生儿的出生体重和巨大儿所占比例分别比较,差异亦均无统计学意义(P>0.05)。③研究组产妇前基线值、快肌收缩最大值、混合肌收缩最大值、混合肌收缩平均值、耐力肌收缩平均值、后基线值分别为(1.4±0.3) μV、(23.8±5.5) μV、(19.9±3.4) μV、(17.2±2.9) μV、(13.7±3.0) μV、(1.3±0.3) μV,均超过对照组的(1.3± 0.3) μV、(20.6±4.4) μV、(17.7±3.3) μV、(14.2±4.1) μV、(11.8±3.4) μV、(1.1±0.3) μV,并且差异均有统计学意义(P<0.05)。而2组产妇耐力肌收缩最大值比较,差异无统计学意义(P>0.05)。 结论旋后肩法用于肩难产产妇助产,较传统耻骨联合上加压法,可改善产妇产后短期内的盆底肌功能。     

手法处理头位难产在少数民族偏远地区的意义

目的 探讨经阴道徒手旋转胎头处理头位难产的临床应用价值.方法 回顾性分析经阴道徒手旋转胎头处理头位难产的病例,分析其异常头先露、先露高低、宫口扩张及胎儿体重与徒手旋转胎头处理后分娩情况.结果 头位难产1356例,占分娩总数的20.56%.对其中1030例孕妇进行了经阴道徒手旋转纠正头先露异常,顺产842例,成功率81.75%;剖宫产141例(13.69%),阴道助产47例(4.56%),失败188例,失败率18.52%.持续性枕后位与枕横位徒手旋转胎头成功率明显高于前不均倾位及高直位(P<0.01);先露S+1以下徒手旋转胎头成功率明显高于S+1以上者(P<0.01);宫口开大4cm以上徒手旋转胎头成功率明显高于宫口开大4cm以下者(P<0.01);胎儿体重3750g以下时,徒手旋转胎头成功率明显高于胎儿体重3750g以上者(P<0.01).结论 重视头盆评分及产程观察,适时经阴道徒手旋转异常头先露,能有效提高头位难产的阴道分娩率,降低剖宫产率,对少数民族偏远地区有重要意义.     

Tracheal rupture in complicated delivery: A case report and review of the literature

A case of distal tracheal rupture is described, literature review reveals two previously reported cases of neonatal distal tracheal rupture, as well as 14 cases of anterior subglottic rupture. All patients had shoulder dystocia, and 59% had associated brachial plexus injury. Delayed diagnosis (>3 days) was common in the distal tracheal group (66%), compared to 0% in the anterior subglottic group. The 2 distal tracheal rupture patients were initially managed conservatively, but ultimately required open repair. Distal tracheal rupture is exceedingly rare and more difficult to diagnose and manage than the more common anterior subglottic rupture.     

Maternal and neonatal outcomes in pregnancies complicated by gestational diabetes. a nation-wide study

Objective: To estimate the association between gestational diabetes mellitus (GDM) and adverse pregnancy and neonatal outcomes in Denmark.

Methods: A population-based cohort study including all singleton pregnancies in Denmark from 2004 to 2010 (n?=?403?092). Maternal complications during pregnancy and delivery and fetal complications were classified according to the International Classification of Diseases 10th Revision.

Results: The final study population consisted of 398?623 women. Of these, 9014 (2.3%) had GDM. Data were adjusted for maternal age, parity, smoking, gestational age, birth weight, BMI, gender of the fetus and calendar year. The risk of preeclampsia, caesarean section (both planned and emergency) and shoulder dystocia was increased in women with GDM. In the unadjusted analysis, the risk of thrombosis was increased by a factor 2 in the GDM patients, but in the adjusted analysis this association disappeared. Post-partum hemorrhage was similar in the two groups. The GDM women had an increased risk of giving birth to a macrosomic neonate although the unadjusted analysis did not show any difference between the two groups. Low Apgar score was increased in the GDM, but this association disappeared in the adjusted analysis. Stillbirth was comparable in the two groups.

Conclusions: Women with GDM still have increased incidence of obstetric and neonatal complications, which could imply that treatment of women with GDM should be tightened.     

Does dystocia during labor pose a risk factor for another non-progressive labor during the subsequent delivery?

Objective: To establish whether failure to progress during labor poses a risk factor for another non-progressive labor (NPL) during the subsequent delivery.

Methods: A retrospective cohort study including singleton pregnancies that failed to progress during the previous labor and resulted in a cesarean section (CS) was conducted. Parturients were classified into three groups for both previous and subsequent labors: CS due to NPL stage I, stage II and an elective CS as a comparison group.

Results: Of 202?462 deliveries, 10?654 women met the inclusion criteria: 3068 women were operated due to NPL stage I and 1218 due to NPL stage II. The comparison group included 6368 women. Using a multivariable logistic regression models, NPL stage I during the previous delivery was found as an independent risk factor for another NPL stage I in the subsequent labor (adjusted odds ratio [OR]?=?2.9; 95% confidence interval [CI]?=?2.4–3.7; p?p?=?0.033; adjusted OR?=?5.3; 95% CI?=?3.7–7.5; p?Conclusion: A previous CS due to a NPL is an independent risk factor for another NPL in the subsequent pregnancy and for recurrent cesarean delivery.     

徒手旋转在头位难产产妇助产护理中的应用

目的:观察并分析在头位难产助产护理中对产妇应用徒手旋转的效果。方法:选取本院产科收治的84例头位难产产妇为研究对象,按入院顺序将其分为对照组(42例,常规助产护理)与观察组(42例,徒手旋转助产护理)。评价两组的助产护理效果。结果:观察组产妇自然分娩率及新生儿Apgar评分显著高于对照组,第二产程时间、产后出血量以及新生儿不良反应发生率则明显低于对照组,数据差异明显,P<0.05。结论:徒手旋转的助产护理方式可缩短头位难产产妇的产程时间,降低剖宫产率及新生儿并发症发生率,确保分娩的顺利进行。
