Inform women that administering epidural analgesia in thelatent phase of labour compared to the active phase oflabour does not increase the risk of assisted vaginal birth. [New 2020]  A

告知betway女,在潜伏期与活跃期采取硬膜外镇痛不会增加阴道助产的风险。[New2020]    A

Encourage women not using epidural analgesia to adopt uprightor lateral positions in the second stage oflabour as this reduces the need for assisted vaginal birth.  A

鼓励未实施硬膜外镇痛的betway女在第二产程中采用直立或侧卧位,因为这会减少对阴道助产的需求。    A

Encourage women using epidural analgesia to adopt lying downlateral positions rather than upright positionsin the second stage of labour as this increases the rate of spontaneous vaginal birth. [New 2020]  A

鼓励采取硬膜外镇痛的betway女在第二产程中采用侧卧位而不是直立位,因为这会增加自然阴道分娩的几率。[New2020]    A

Recommend delayed pushing for 1–2 hours in nulliparous womenwith epidural analgesia as this may reduce theneed for rotational and midpelvic assisted vaginal birth.  B

建议硬膜外镇痛的初产betway延迟1-2小时用力,因为这可以减少中骨盆平面阴道助产和旋转胎头的需要。    B

Do not routinely discontinue epidural analgesia during pushingas this increases the woman’s pain with no evidence of a reduction in the incidence of assisted vaginalbirth. [New 2020]  A

不要在用力过程中常规停用硬膜外镇痛,因为这会增加betway女的疼痛,而且也没有证据表明能使阴道助产的发生率降低。[New2020]    A

There is insufficient evidence to recommend any particularregional analgesia technique in terms of reducingthe incidence of assisted vaginal birth. [New  2020]  A

没有足够的证据建议采取特定的局部镇痛技术可以减少阴道助产的发生率。[New2020]    A

没有足够证据建议在第二产程常规手法旋转胎方位可以减少阴道助产的风险。[New2020]    B

如何评价阴道助产?

Use a standard classification system for assisted vaginal birthto promote safe clinical practice, effectivecommunication between health professionals and audit of outcomes.  D

对阴道助产使用标准分类系统,以促进临床实践的安全性,以及卫生专业人员之间的有效沟通和结果审核。    D

阴道助产顺利的必备条件?

Safe assisted vaginal birth requires a careful assessment ofthe clinical situation, clear communication withthe woman and healthcare personnel, and expertise in the chosen procedure.   D

安全的阴道助产需要对临床状况仔细评估、医疗保健人员与betway女进行清楚的沟通,并具备所选方法的专业知识。    D

超声能否用于阴道助产前的评估?

Ultrasound assessment of the fetal head position prior toassisted vaginal birth is recommended where uncertainty exists followingclinical examination. [New 2020]  A

如果临床检查存在不确定性,推荐阴道助产前对胎头位置进行超声评估。[New2020]    A

There is insufficient evidence to recommend the routine use ofabdominal or perineal ultrasound forassessment of the station, flexion and descent of the fetal head in the second stage of labour. [New 2020]  C

没有足够证据建议常规使用腹部或会阴超声来评估第二产程胎头的位置、俯屈和下降程度。[New2020]    C

在产房进行阴道助产前应征得口头同意,讨论应记录在相应文件中。 √

When midpelvic orrotational birth is indicated, therisks and benefits of assisted vaginal birth should be compared with the risks and benefits of second stage caesareanbirth for the given circumstances andskills of the operator. Written consent should be obtained for a trial of assisted vaginal birth in an operating theatre. [New2020]    √

当有中骨盆平面或需旋转胎头指征时,应根据操作者的特定情况和技能,将阴道助产的利弊与第二产程剖宫产的利弊进行比较。在手术室进行阴道助产应获得书面同意。[New2020]    √

实施阴道助产

阴道助产的手术人员

Assisted vaginal birth should be performed by, or in thepresence of, an operator who has the knowledge, skillsand experience necessary to assess the woman, complete the procedure and manageany complications that arise.  D

阴道助产的督导人员

An experienced operator, competent at midpelvic births, should be present from the outset to supervise allattempts at rotational or midpelvic assisted vaginal birth.  D

一个能够胜任中骨盆平面助产的经验丰富的操作者,应该从一开始就在场督导旋转胎头或中骨盆平面阴道助产的所有尝试。D

何处进行阴道助产?

Non-rotational low-pelvic and lift out assisted vaginal birthshave a low probability of failure and most procedurescan be conducted safely in a birth room. [New 2020]  C

不需旋转胎头的骨盆出口平面和上抬手柄的阴道助产的失败概率很低,因此大都可在产房安全进行。[New2020]    C

Assisted vaginal births that have a higher risk of failureshould be considered a trial and be attempted in aplace where immediate recourse to caesarean birth can be undertaken.  C

具有较高失败风险的阴道助产应视为一种试验收,并需在可立即剖宫产的场所进行。C

阴道助产的器械

The operator should choose the instrument most appropriate tothe clinical circumstances and their level ofskill.  √

操作者应根据临床情况和自身技术水平选择最合适的器械。 √

Operators should be aware that forceps and vacuum extractionare associated with different benefits and risks;failure to complete the birth with a single instrument is more likely with vacuum extraction, but maternal perineal trauma is morelikely with forceps. [New 2020]  A

操作者应意识到,产钳和胎吸助产各有利弊,单纯使用胎头吸引术可能无法完成分娩,而产钳助产造成母亲会阴裂伤的可能性更大。[New2020]    A

Operators should be aware that soft cup vacuum extractorshave a higher rate of failure but a lower incidence of neonatal scalp trauma.[New 2020]  A

操作者应注意,柔软罩杯的胎头吸引器失败率较高,但新生儿头皮损伤的发生率较低。[New2020]    A

Rotational births should be performed by experienced operators;the choice of instrument depending on theclinical circumstances and expertise of the individual. The options include Kielland’s rotational forceps, manual rotationfollowed by direct traction forceps or vacuum, and rotational vacuum extraction.  C

旋转胎头分娩应由经验丰富的操作者进行,根据临床情况和专业知识选择合适器械,包括Kielland旋转产钳、手动旋转直接牵引式产钳、胎头吸引器、旋转胎头吸引器。  C

何时中止胎头吸引术?其后续处理如何?

Discontinue vacuum-assisted birth where there is no evidence ofprogressive descent with moderate traction during each pull of a correctly applied instrument by anexperienced operator. [New 2020]  √

经验丰富的操作者在每次宫缩时使用合适的胎头吸引器适度牵引力而先露没有进行性下降,应停止胎头吸引术。[New2020]    √

Complete vacuum-assisted birth in the majority of cases with amaximum of three pulls to bring the fetalhead on to the perineum. Three additional gentle pulls can be used to ease the head out of the perineum. [New 2020]  √

大多数情况下胎头吸引最多可牵拉三次,使胎头靠近会阴,另外三次缓慢轻柔牵拉使胎头娩出会阴。[New2020]    √

If there is minimal descent with the first two pulls of avacuum, the operator should consider whether theapplication is suboptimal, the fetal position has been incorrectly diagnosed or there is cephalopelvic disproportion. Less experiencedoperators should stop and seek a second opinion. Experienced operators should re-evaluate the clinical findings andeither change approach ordiscontinue the procedure. [New 2020]  √

如果在前两次胎吸先露几乎不下降,操作者应考虑使用胎头吸引器是否不太合适,胎儿位置是否判断错误,是否存在头盆不称。经验不足的操作者应停下来征求别人的意见, 经验丰富的操作者需重新评估临床情况,或更改阴道助产方法或停止阴道助产。[New2020]    √

Discontinue vacuum-assisted birth if there have been two ‘pop-offs’ of the instrument. Less experienced operators should seek senior support after one ‘pop-off’ to ensure the woman has the best chance of a successful assisted vaginal birth. [New 2020]  √

若牵引时吸引器滑脱两次,应停止胎头吸引。经验不足的操作者应在吸引器滑脱一次马上寻求上级的帮助,以确保betway女最高的阴道助产的成功机率。[New2020]    √

The rapid negative pressure application for vacuum-assistedbirth is recommended as it reduces the duration of theprocedure with no difference in maternal and neonatal outcomes. [New 2020]  √

建议在胎吸助产中快速使用负压,以缩短助产时长,且不增加母婴不良结局。[New2020]    √

The use of sequential instruments is associated with anincreased risk of trauma to the infant. However, the operator needs to balance the risks of a caesarean birthfollowing failed vacuum extraction with therisks of forceps birth following failed vacuum extraction.  B

虽然连续使用助产器械会导致胎儿损伤的风险,但操作者需要衡量胎头吸引失败后改用剖宫产或产钳助产带来的风险。 B

Obstetricians should be aware of the increased neonatalmorbidity following failed vacuum-assisted birth and/or sequential use of instruments, and should inform theneonatologist when this occurs to ensureappropriate care of the baby.  √

产医生应意识到胎头吸引助产失败和/或连续使用助产器械可能导致新生儿发病率升高,并应在发生这种情况时通知新生儿医生,以确保新生儿得到适当的护理。  √

Obstetricians should be aware of the increased risk ofobstetric anal sphincter injury (OASI) followingsequential use of instruments. [New 2020]  C

产医生应意识到连续使用助产器械后,产betway肛门括约肌损伤(OASI)的风险增加。[New2020]    C

何时中止产钳助产?其后续处理如何?

Discontinue attempted forceps birth where the forceps cannot beapplied easily, the handles do notapproximate easily or if there is alack of progressive descent with moderate traction. [New 2020]  B

若产钳不好使用,手柄不易扣合,或适度牵引力先露无进行性下降,则应停止产钳助产。[New2020]    B

Discontinue rotational forceps birth if rotation is not easilyachieved with gentle pressure. [New 2020]  B

如果在轻柔的压力不易旋转,则停止产钳旋转胎头。[New2020]    B

Discontinue attempted forceps birth if birth is not imminentfollowing three pulls of a correctly applied instrumentby an experienced operator. [New 2020]  B

如果有经验的操作者在正确使用器械反复三次牵拉胎儿无法立即娩出,应停止产钳助产。[New2020]    B

If there is minimal descent with the first one or two pulls ofthe forceps, the operator should consider whetherthe application is suboptimal, the position has been incorrectly diagnosed or there is cephalopelvic disproportion. Less experiencedoperators should stop and seek a second opinion. Experienced operators should re-evaluate the clinical findings andeither change approach ordiscontinue the procedure. [New 2020]  √

如果一次或两次产钳牵拉后先露几乎不下降,操作者应考虑产钳是否不太合适,胎儿位置是否判断错误,是否存在头盆不称。经验不足的操作者应停下来征求别人的意见,,经验丰富的操作者需重新评估临床情况,或更改阴道助产方法或停止阴道助产。 [New2020]    √

作为阴道助产准备的一部分,应与betway女讨论会阴侧切开术。[New2020]    √

In the absence of robust evidence to support either routine orrestrictive use of episiotomy at assisted vaginalbirth, the decision should be tailored to the circumstances at the time and the preferences of the woman. The evidence to support use ofmediolateral episiotomy at assisted vaginal birth interms of preventing OASI is stronger for nulliparous women and for birth via forceps. [New 2020]  B

在无有力证据支持阴道助产常规或限制性会阴切开术的情况下,应根据当时临床情况和betway女的意愿作决定。证据支持初产betway和产钳助产者进行会阴侧切开术可以更有效地预防产肛门括约肌损伤(OASI)。[New2020]    B

When performing a mediolateral episiotomy the cut should be ata 60 degree angle initiated when the head isdistending the perineum. [New 2020]  B
