Distribution of genital tract trauma in childbirth and related postnatal pain

Do perfectionism, body image concerns, and intimacy predict genitopelvic pain in the postpartum? A prospective study of new mothers

BACKGROUND

Genitopelvic pain following childbirth is common and likely to challenge the psychological, relational, and sexual well-being of new mothers. While genitopelvic pain generally decreases during the postpartum period, personal and interpersonal characteristics may explain why genitopelvic pain persists beyond the period of physical recovery in some mothers. Body image concerns, increased stress, and relationship challenges would be particularly salient during pregnancy and the postpartum period, which could put new mothers at greater risk of sexual difficulties. Also, mothers may display a negative appraisal regarding genitopelvic pain and doubt their ability to cope with it, which may contribute to the pain.

AIM

The current study aimed to examine the role of perfectionism, body image concerns, and perceived intimacy in the occurrence and change in genitopelvic pain in new mothers in postpartum.

METHODS

A total of 211 new mothers and their partners were recruited for a larger prospective dyadic study on the transition to parenthood.

OUTCOMES

Mothers completed a single item assessing genitopelvic pain, in addition to brief validated questionnaires measuring perfectionism, body image concerns, and perceived couple intimacy during pregnancy and at 4, 8, and 12 months postpartum.

RESULTS

Five multilevel modeling analyses revealed that adaptive perfectionism, maladaptive perfectionism, and body image concerns were associated with a higher occurrence of genitopelvic pain from 4 to 12 months postpartum. Mothers' and partners' perceived intimacy was not significantly related to new mothers' genitopelvic pain. None of the predictors modified the trajectory of genitopelvic pain over time.

CLINICAL IMPLICATIONS

Raising awareness among health care professionals regarding the role of perfectionism and body image concerns in genitopelvic pain may help them identify new mothers at risk of chronic genitopelvic pain, while offering a new avenue of intervention.

STRENGTHS AND LIMITATIONS

There has been little research examining the role of perfectionism, body image concerns, and intimacy in postpartum genitopelvic pain. Based on a longitudinal prospective approach, this study identified perfectionism and body image concerns as significant predictors of postpartum genitopelvic pain. However, prepregnancy genitopelvic pain, genitopelvic pain intensity, and sexual distress were not measured.

CONCLUSION

Adaptive and maladaptive perfectionism and body image concerns are associated with new mothers' genitopelvic pain up to 12 months postpartum.

The REPAIR study: oral antibiotics to prevent infection and wound dehiscence after obstetric perineal tear-a double-blinded placebo controlled randomized trial

BACKGROUND

Approximately 85% of women experience an obstetric tear at delivery and up to 25% subsequently experience wound dehiscence and/or infection. Previous publications suggest that intravenous antibiotics administrated during delivery reduces this risk. We do not know if oral antibiotics given after delivery can reduce the risk of wound dehiscence or infection. Our aim is to investigate whether three doses of oral antibiotics (amoxicillin 500 mg/clavulanic acid 125 mg) given after delivery can reduce the risk of wound dehiscence and infection in patients with a second-degree obstetric tear or episiotomy.

METHODS

We will perform a randomized, controlled, double-blinded study including 221women in each arm with allocation 1:1 in relation to the randomization. The study is carried out at Department of Obstetrics & Gynecology, Herlev University Hospital, Copenhagen, Denmark. The women will be included after delivery if they have had a second-degree tear or episiotomy. After inclusion, the women will have a clinical follow-up visit after 1 week. The tear and healing will be evaluated regarding signs of infection and/or dehiscence. The women will again be invited for a 1-year clinical examination including ultrasound. Questionnaires exploring symptoms related to the obstetric tear and possible complications will be answered at both visits. Our primary outcome is wound dehiscence and/or wound infection, which will be calculated using χ2 tests to compare groups. Secondary outcomes are variables that relate to wound healing, as pain, use of painkillers and antibiotics, need for further follow-up, as well as outcomes that may be related to the birth or healing process, urinary or anal incontinence, symptoms of prolapse, female body image, and sexual problems.

DISCUSSION

Reducing the risk of wound dehiscence and/or infection would decrease the number of control visits, prevent the need for longer antibiotic treatment, and possibly also decrease both short-term and long-term symptoms. This would be of great importance so the mother, her partner, and the baby could establish and optimize their initial family relation.

TRIAL REGISTRATION

The conduction of this study is approved the 2/2-2023 with the EU-CT number: 2022-501930-49-00.

A single group trial (before - after) on impact of physiotherapeutic intervention package on relief from low back pain of pregnant women

Introduction

More than half of the women have low back pain (LBP) at some point during pregnancy; the intensity of back pain increases as the pregnancy progresses. Such changes increase their risk for musculoskeletal disorders and fall injuries.

Aim and Objective

Our study's objective was to estimate the prevalence of LBP in antenatal and postnatal cases of pregnancy in PGIMER, Chandigarh and to ascertain impact of a training intervention on incidence and severity of LBP in the study subjects.

Methodology

A single group trial (before and after) on impact of physiotherapeutic intervention package on relief from LBP in pregnant women in between 20 and 35 years of age group were selected. The study duration was one year. The numeric pain rating scale was taken for measuring pain intensity at different levels. Where 0 indicates no pain, 1-3 indicates mild pain (which may be nagging, annoying, and interfering little with activities of daily livings (ADLs)), 4-6 indicates moderate pain (interferes significant with ADLs), and 7-10 indicates severe pain (Disabling, unable to perform ADLs). As per available time, it was decided to include at least 30 subjects in the study.

Results

Initially 45 patients were enrolled. Of those, 30 patients were suffering from backache, that is, 67% of the total and 33% did not have any backache. There were no backaches reported in the first trimester, five cases were in the second trimester, and 18 cases were in the third trimester. Of 30 patients, 11 were less than 25 years of age and remaining 19 patients were in the age group of 26-35 years.

Women's experiences of the injury, recovery and desire for rehabilitation after a second-degree vaginal tear-a qualitative study

Introduction and hyposthesis

Eighty-five percent of all vaginal deliveries cause some form of obstetric tear injury. To our knowledge, there are no studies exploring experiences after second-degree tear. Therefore, our study aimed to investigate the experiences of a second-degree vaginal tear regarding aspects of the recovery and need for healthcare and rehabilitation.

Methods

Individual semi-structured interviews were performed and analysed with a qualitative, inductive descriptive approach.

Results

A group of 18 women with a second-degree vaginal tear after delivery were included. Four main categories with associated subcategories were found: (1) feeling uncertainty, with subcategories: not knowing what is normal, concern, confusion and uncertainty regarding pelvic floor muscle training; (2) feeling of security, with subcategories: I have no/I can handle the symptoms, trust in the healthcare system and I have sufficient knowledge; (3) not prioritizing myself, with the subcategories: I cannot find time and others have bigger problems; (4) lack of trust in healthcare providers, with the subcategories: feeling forgotten, not being taken seriously, distrust of the competence of the healthcare providers and resignation.

Conclusion

Women who suffer from a second-degree vaginal tear after pregnancy can feel safe when needs are met but uncertainty is also common when available healthcare and information are perceived as insufficient. The women also feel uncertainty about what is normal after the tear and how to perform pelvic floor exercises.

Childbirth Related Labial Trauma Management in the UK: A Brief Report

Trauma to the labia occurs in up to 49% of vaginal births¹. Trauma to the perineal body resulting from childbirth is well defined using widely used categories, and recommended management of perineal body trauma is based on high level evidence. Currently no similar evidence exists to inform the classification or management of labial trauma. This is reflected in variation in clinical practice with some practitioners favouring suturing of labial trauma, whilst others favour healing by secondary intention. A survey of practice was undertaken in three NHS organisations, over a five-week period in 2019 with data collected on 332 vaginal births. Overall, 47.3% (n=157) of women sustained labial trauma, of whom 29.3% (n=46) sustained trauma described as involving skin and underlying tissues. Of the labial trauma which involved skin and underlying tissues 76.0% (n=35) was sutured and the remainder unsutured. The survey confirmed a lack of consistency in practice and the need for further research to inform care for women.

Birth tears after spontaneous and vacuum-assisted births with different vacuum cup systems - a retrospective cohort study

Objectives Birth tears are a common complication of vaginal childbirth. We aimed to evaluate the outcomes of birth tears first by comparing the mode of vaginal birth (VB) and then comparing different vacuum cups in instrumental VBs in order to better advise childbearing women and obstetrical professionals. Methods In a retrospective cohort study, we analyzed nulliparous and multiparous women with a singleton pregnancy in vertex presentation at ≥37 + 0 gestational weeks who gave birth vaginally at our tertiary care center between 06/2012 and 12/2016. We compared the distribution of tear types in spontaneous births (SBs) vs. vacuum-assisted VBs. We then compared the tear distribution in the vacuum group when using the Kiwi Omnicup or Bird's anterior metal cup. Outcome parameters were the incidence and distribution of the different tear types dependent on the mode of delivery and type of vacuum cup. Results A total of 4549 SBs and 907 VBs were analyzed. Birth tear distribution differed significantly between the birth modes. In 15.2% of women with an SB an episiotomy was performed vs. 58.5% in women with a VB. Any kind of perineal tear was seen in 45.7% after SB and in 32.7% after VB. High-grade obstetric anal sphincter injuries (OASIS) appeared in 1.1% after SB and in 3.1% after VB. No significant changes in tear distribution were found between the two different VB modes. Conclusions There were more episiotomies, vaginal tears and OASIS after VB than after SB. In contrast, there were more low-grade perineal and labial tears after SB. No significant differences were found between different vacuum cup systems, just a slight trend toward different tear patterns.

Prediction of levator ani muscle avulsion by genital tears after vaginal birth-a prospective observational cohort study

INTRODUCTION

Visible birth tears and levator ani muscle (LAM) trauma are common after birth. For the diagnosis of LAM trauma ultrasound evaluation is advisable. As ultrasound equipment and trained personnel are not available everywhere at all times, we aimed to evaluate whether specific overt birth tears are an indicator for LAM trauma.

METHODS

In a prospective cohort study at our center from March 2017-April 2019, we evaluated vaginal births of nulliparous women with singletons in vertex presentation ≥ 36 + 0 gestational weeks for LAM trauma by translabial ultrasound and for overt birth tears by inspection. We then calculated the association of overt birth tears with complete LAM avulsion.

RESULTS

Of 213 women, 23.9% had any kind of LAM trauma, with 14.1% being complete avulsions. In univariate analysis, solely high-grade perineal tears (OASIS) were significantly associated with complete LAM avulsions.

CONCLUSIONS

Fourteen percent of women suffered a complete LAM avulsion after vaginal birth, with OASIS being the only associated parameter of significance. The occurrence of such trauma might be an indicator for a mismatch between the size of the fetus and the structures of the birth canal, leading to birth trauma. Assessing for LAM trauma by translabial ultrasound in women with OASIS might be worthwhile.

How do sustained birth tears after vaginal birth affect birth tear patterns in a subsequent birth?

Background Tears are common after vaginal birth, and different impact factors are known. However, the impact of tears from a previous birth to the tears of a subsequent birth is unknown. Therefore, we aimed to evaluate the distribution of birth tear patterns according to the sustained tears in a previous birth, in addition to other impact factors. Methods In a retrospective cohort study, we evaluated all women up to parity 4 with subsequent vaginal, singleton births of vertex presentation at ≥37 + 0 gestational weeks between 1/2005 and 12/2016. Their tears were grouped into tear patterns and were analyzed by parity. Tear patterns in the subsequent births were analyzed in association to the patterns of the previous births and impact factors were evaluated. Results We counted 4017 births in 1855 women [P1: 1368 (34.1%), P2: 1730 (43.1%), P3: 741 (18.4%), P4: 178 (4.4%)]. The frequency of tears and episiotomies decreased with higher parity, whereas the frequency of intact perineum increased. Twenty-eight different unique tear patterns were found. We could show that birth tear patterns changed with increasing parity and were associated with sustained tears in a previous birth. In addition, some impact factors on tear patterns could be identified. Conclusion The distribution of the single tear types is in accordance with the current literature. However, it is new that distinct tear patterns are associated to sustained tear patterns of previous births. Furthermore, we demonstrated some weak associations of tear patterns to certain impact factors, such as more episiotomies, low-grade perineal or vaginal tears isolated or in combination with other tears with increasing fetal weight and head circumference in the higher parities, and with a longer duration of the second stage and the pushing phase in lower parities.

Factors associated with persistent pain after childbirth: a narrative review

A systematic literature search was performed to identify studies that reported risk factors for persistent pain after childbirth. Many studies have sought to identify risk factors for post-delivery pain in different populations, using different methodologies and different outcome variables. Studies of several different but interrelated post-partum pain syndromes have been conducted. Factors strongly and specifically associated with persistent incisional scar pain after Caesarean delivery include a coexisting persistent pain problem in another part of the body and severe acute postoperative pain. For persistent vaginal and perineal pain, operative vaginal delivery and the magnitude of perineal trauma have been consistently linked. History of pregnancy-related and pre-pregnancy back pain and heavier body weight are robust risk factors for persistent back pain after pregnancy. Unfortunately, limitations, particularly small samples and lack of a priori sample size calculation designed to detect specific effect sizes for risk of persistent pain outcomes, preclude definitive conclusions about many other predictors and the strength of outcome associations. In future studies, assessments of specific phenotypes using a rigorous analysis with appropriate predetermined sample sizes and validated instruments are needed to allow elucidation of stronger and reliable associations. Interventional studies targeting the most robustly associated, modifiable risk factors, such as acute post-partum pain, may lead to solutions for the prevention and treatment of these common problems that impact a large population.

[Perineal risk and obstetrical protection: A survey with birth professionals]

OBJECTIVES

The main objective was to evaluate the practices declared by birth professionals in the Lorraine region about perineal obstetric protection (any perineal tear combined). The secondary objective was to evaluate prevention measures performed in practice by birth professionals according to the perineal risk subjectively estimated for each obstetric situation.

METHODS

This is a practice survey conducted through an anonymous questionnaire distributed to birth professionals (gynecologists, interns, midwife and midwife student) in October 2016. Topics covered concerned maternal, obstetric and fetal risk factors associated with perineal (1st to 4th degrees) lesions and the associated protective measures. A descriptive analysis of the data collected was conducted.

RESULTS

One hundred and five professionals answered the questionnaire. The identified risk factors were consistent with those highlighted in the literature. Other factors, not known as associated with perineal risk, were cited by professionals (smoking, phototype). If the professional perceived a significant perineal risk, they more frequently practiced an episiotomy (15% vs. 0%, P<0.001) or considered that the delivery should be performed by an obstetrician (34% vs 8%, P<0.001).

CONCLUSION

This evaluation shows that birth professionals know the main risk factors for perineal injury. On the other hand, they easily use perineal protection maneuvers (episiotomy for example) without real demonstrated effectiveness.

Infection and wound breakdown in spontaneous second-degree perineal tears: An exploratory mixed methods study

BACKGROUND

Perineal trauma affects large numbers of women who have a vaginal birth. This study explores the incidence, etiology and women's experiences of wound infection/breakdown associated with spontaneous second degree tears.

METHODS

This was an exploratory mixed methods study set in an urban tertiary National Health Service hospital in 2014-2015. The study included a prospective observational study of second-degree tears using electronic patient records. Infection was defined using criteria adapted from Public Health England's Surgical Site Infection Surveillance Service. We also did a case-control study of maternity records to explore factors associated with perineal infection/wound breakdown, and semi-structured interviews with a purposeful sample of women who experienced wound infection/breakdown.

RESULTS

Of 2892 vaginal births during the study period, 76.8% sustained perineal trauma, with second-degree tears most commonly recorded (n = 828/28.6%). Sixteen (1.9%) had a documented infection/wound breakdown which were associated with "compromised wound status" (increased severity of wound/poor suturing; P = 0.033) Women complained of a lack of information about their perineum and poor postnatal surveillance by midwives and physicians. Diagnosis and treatment were often delayed by clinicians' reliance on external signs of wound infection. Although the sample size was small, there were no differences in rates of infection between sutured and unsutured second-degree tears.

CONCLUSIONS

Although second-degree tears were common after vaginal birth, wound infection/breakdown was relatively uncommon. Women who report feeling unwell or develop pyrexia postnatally should be assessed urgently. A prospective longitudinal study exploring the long-term sequelae of second-degree tears is needed.

Incidence of perineal pain and dyspareunia following spontaneous vaginal birth: a systematic review and meta-analysis

INTRODUCTION AND HYPOTHESIS

Perineal pain and dyspareunia are experienced by women undergoing a vaginal birth that can have short and longer term physical and psychological morbidities. This review aimed to determine the incidence of perineal pain and dyspareunia following spontaneous vaginal birth (SVB) with intact perineum, first and second-degree perineal trauma or episiotomy.

METHODS

Searches of MEDLINE, EMBASE, CINAHL, AMED and MIDIRS (inception - December 2017) were undertaken with selection criteria of any study evaluating the effect of intact perineum, first- or second-degree perineal trauma on perineal pain or dyspareunia in women with SVB.

RESULTS

Eighteen studies (8 RCTs and 10 NRSs) were included. Fourteen and 12 studies were undertaken to assess perineal pain and dyspareunia after SVB, respectively. Meta-analysis of 16 studies (3133 women) demonstrated that women at 2 days postpartum experienced nearly the same incidence of perineal pain whether perineal trauma existed or not. At 4-10 days postpartum there was a significant reduction in the incidence of perineal pain for both presence and absence of any perineal trauma. Episiotomy was associated with the highest rate of perineal pain. The incidence of dyspareunia was high at resumption of sexual intercourse following SVB with an intact perineum. At 12 months, women still experienced dyspareunia whether perineal trauma existed or not.

CONCLUSIONS

Women experience perineal pain and dyspareunia regardless of the presence or absence of perineal trauma after SVB; nonetheless, the reported incidence is higher if perineal trauma occurred.

Midwifery management of second-degree perineal tears in New Zealand: A cross-sectional survey of practice

BACKGROUND

Second-degree tears are the most common form of perineal trauma occurring after vaginal birth managed by New Zealand midwives, although little is known about midwives' perineal practice.

AIM

The aim of this study was to identify how midwives managed the last second-degree perineal tear they treated and the level to which their practice reflects National Institute for Health and Care Excellence guidelines.

METHODS

An (anonymous) online survey was conducted over a six-week period in 2013. New Zealand midwives who self-identified as currently practising perineal management and could recall management of the last second-degree tear they treated were included in the analysis.

FINDINGS

Of those invited, 645 (57.1% self-employed, 42.9% employed) were eligible and completed surveys. Self-employed midwives reported greater confidence (88.0% vs 74.4%, p<0.001) and more recent experience (85.1% vs 57.4%, p<0.001) with perineal repair than employed midwives. Midwives who left the last second-degree tear unsutured (7.3%) were more likely to report low confidence (48.9% vs 15.4%, p<0.001) and less recent experience with repair (53.2% vs 24.7%, p<0.001), and were less likely to report a digital-rectal examination (10.6% vs 49.0%, p<0.001), compared to midwives who sutured. Care consistent with evidence-based guidelines (performing a digital-rectal examination, 59.4% vs 49.3% p=0.005; optimal suturing techniques, 62.2% vs 48.7%, p=0.001) was associated with recent perineal education.

CONCLUSIONS

Midwives' management of the last second-degree perineal tear is variable and influenced by factors including: employment status, experience, confidence, and perineal education. There is potential for improvement in midwives' management through increased uptake of evidence-based guidelines and through ongoing education.

Retrospective analysis of episiotomy prevalence

OBJECTIVE

This study was performed to determine the rate of episiotomy.

MATERIAL AND METHODS

This retrospective was conducted in 3 state hospitals located in 3 cities in the Central Anatolia region of Turkey. Ethics committee approval was received for this study. Also, institutional permissions from the institutions where the study was conducted were obtained before the study. The sample of the study consisted of 8587 women. The data of the study were collected by analyzing birth records in archive records.

RESULTS

The average age of the women was 26.16±5.9 years, the average number of deliveries was 2.19±1.2, and 52.0% of the women who gave birth via vaginal delivery underwent episiotomy. The rate of episiotomy was found to be 93.3% in primipara women and 30.2% in multipara women. It was determined that neonatal weight did not affect the episiotomy rate, and that neonatal height was higher in deliveries with episiotomy and suture. Also, it was determined that as the age and parity of the women decreased, the rate of episiotomy increased.

CONCLUSION

The rate of episiotomy was observed to be high, especially in primipara women.

Antenatal maternal education for improving postnatal perineal healing for women who have birthed in a hospital setting

BACKGROUND

The female perineum becomes suffused and stretched during pregnancy, and further strain during vaginal childbirth contributes to approximately 85% of women experiencing some degree of trauma to the perineal region. Multiple factors play a role in the type and severity of trauma experienced, including parity, delivery method, and local practices. There is ongoing debate about best midwifery practice to reduce perineal trauma. Once perineal trauma has occurred, treatment also varies greatly, depending on its degree and severity, local practice and customs, and personal preference. In order to optimise wound-healing outcomes, it is important that wounds are assessed and managed in an appropriate and timely manner. A perineal wound may cause significant physical and/or psychological impact in the short or long term, however little evidence is available on this subject.Antenatal education serves to prepare women and their partners for pregnancy, delivery and the postpartum period. The delivery of this education varies widely in type, content, and nature. This review examined antenatal education which is specifically tailored towards perineal care and wound healing in the postnatal period via formal channels. Appropriate patient education positively impacts on wound-healing rates and compliance with wound care. Risk factors that contribute to the breakdown of wounds and poor healing rates may be addressed antenatally in order to optimise postnatal wound healing. It is important to assess whether or not antenatal wound-care education positively affects perineal healing, in order to empower women to incorporate best practice, evidence-based treatment with this important aspect of self-care in the immediate postnatal period.

OBJECTIVES

To evaluate the effects of antenatal education on perineal wound healing in postnatal women who have birthed in a hospital setting, and who have experienced a break in the skin of the perineum as a result of a tear or episiotomy, or both.

SEARCH METHODS

We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (30 September 2017), ClinicalTrials.gov (8th September 2017), the WHO International Clinical Trials Registry Platform (ICTRP) (8th September 2017) and reference lists of retrieved studies.

SELECTION CRITERIA

We considered randomised controlled trials (RCTs) which referred to all formal methods of antenatal education and addressed care of a potential perineal wound as a result of a tear or episiotomy, which was experienced by pregnant women who planned to give birth within a hospital setting.Trials using a cluster-RCT and a quasi-randomised design would have been eligible for inclusion in this review but none were identified. Cross-over trials were not eligible for inclusion in this review. Studies published in abstract form would have been eligible for inclusion in this review, but none were identified.We planned to consider all formal methods of antenatal education which addressed care of a perineal wound. We also planned to consider all contact points where there was an opportunity for formal education, including midwifery appointments, antenatal education classes, obstetrician appointments, general practitioner appointments and physiotherapist appointments.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed titles and abstracts of the studies identified by the search strategy for their eligibility.

MAIN RESULTS

No studies met the inclusion criteria for this review. We excluded one study and one other study is ongoing.

AUTHORS' CONCLUSIONS

We set out to evaluate the RCT evidence pertaining to the impact of antenatal education on perineal wound healing in postnatal women who have birthed in a hospital setting, and who experienced a break in the skin of the perineum as a result of a tear or episiotomy, or both. However, no studies met the inclusion criteria. There is a lack of evidence concerning whether or not antenatal education relating to perineal wound healing in this cohort of women will change the outcome for these women in relation to wound healing, infection rate, re-attendance or re-admission to hospital, pain, health-related quality of life, maternal bonding, and negative emotional experiences. Further study is warranted in this area given the significant physical, psychological and economic impact of perineal wounds, and the large proportion of childbearing women who have experienced a postnatal wound. The benefits of any future research in this field would be maximised by incorporating women in a range of socio-economic groups, and with a range of healthcare options. This research could take both a qualitative and a quantitative approach and examine the outcomes identified in this review in order to assess fully the potential benefits of a tailored antenatal package, and to make recommendations for future practice. There is currently no evidence to inform practice in this regard.

Active delivery of the anterior arm and incidence of second-degree perineal tears: a clinical practice evaluation

BACKGROUND

Evaluate the feasibility of active delivery of the anterior arm during spontaneous delivery. This maneuver could decrease incidence of second-degree perineal tears because it reduces fetal biacromial diameter.

METHODS

An observational comparative prospective study was conducted at our teaching maternity from July 2012 to March 2013. The study included 199 nulliparous women ≥18 years, who met the following criteria: singleton pregnancy, vaginal delivery with occiput anterior presentation, on epidural analgesia, from 37 weeks of gestation onward. The distribution of rate and type of perineal tears were compared between two groups: a non-exposed group and a group exposed to the maneuver.

RESULTS

A total of 101 patients were exposed to Couder's maneuver (CM) and 98 patients were not exposed. In the intervention group, 3 failures of the maneuver were reported. The maneuver was considered easy in 80% of cases, moderately easy in 12% and difficult in 8% of cases. There was a significant difference (p = 0.03) in the distribution of perineal tears between the two groups. There was a significant reduction (p < 0.001) in the number of second-degree perineal tears in the patients exposed to CM. There was no significant difference in the rate of anterior perineal trauma between the exposed and non-exposed arms.

CONCLUSIONS

CM in primiparous women at term is feasible with a low failure rate and influences the distribution of perineal tears by lowering second-degree perineal tears in a highly significant manner (p <0.01).

Muscle function of the pelvic floor in healthy, puerperal women with pelvic floor dysfunction

OBJECTIVES

To understand the function of the pelvic floor muscles (PFM) at different ages in healthy women and in puerperal women with pelvic floor dysfunctions (PFD) and to ascertain whether there are differences among them.

MATERIAL AND METHODS

A descriptive cross-sectional study was conducted between June 2014 and September 2016 and included 177 women, 70 of whom had no symptoms of PFD, 53 primiparous mothers in late postpartum and 54 with PFD. The function of the PFM was measured through vaginal palpation (quality of the contraction); manometry (force); dynamometer (tone, strength, and response to stretching), and surface electromyography (neuromuscular activity and resistance).

RESULTS

The healthy women showed superior values for PFM tone, maximum strength, neuromuscular activity and resistance than the puerperal mothers and the women with PFD (P<.01). The puerperal women and those with PFD showed similar functional PFM values (P>.05). The muscle function of the healthy women did not vary significantly with age, except in the case of tone, which was lower in the women older than 46 years (P=.004).

CONCLUSIONS

Age and births decrease the baseline tone of the PFM in healthy women. Therefore, lower strength, resistance and neuromuscular activity appear to be the main difference between the PFM of women with PFD and the PFM of healthy women.

Perineal resuturing versus expectant management following vaginal delivery complicated by a dehisced wound (PREVIEW): a nested qualitative study

OBJECTIVE

To explore women's lived experiences of a dehisced perineal wound following childbirth and how they felt participating in a pilot and feasibility randomised controlled trial (RCT).

DESIGN

A nested qualitative study using semistructured interviews, underpinned by descriptive phenomenology.

PARTICIPANTS AND SETTING

A purposive sample of six women at 6-9 months postnatal who participated in the RCT were interviewed in their own homes.

RESULTS

Following Giorgi's analytical framework the verbatim transcripts were analysed for key themes. Women's lived experiences revealed 4 emerging themes: (1) Physical impact, with sub-themes focusing upon avoiding infection, perineal pain and the impact of the wound dehiscence upon daily activities; (2) Psychosocial impact, with sub-themes of denial, sense of failure or self-blame, fear, isolation and altered body image; (3) Sexual impact; and (4) Satisfaction with wound healing. A fifth theme 'participating in the RCT' was 'a priori' with sub-themes centred upon understanding the randomisation process, completing the trial questionnaires, attending for hospital appointments and acceptability of the treatment options.

CONCLUSIONS

To the best of our knowledge, this is the first qualitative study to grant women the opportunity to voice their personal experiences of a dehisced perineal wound and their views on the management offered. The powerful testimonies presented disclose the extent of morbidity experienced while also revealing a strong preference for a treatment option.

Payback case studies (n = 12): in-depth case studies of HTA programme-funded research.

RESULTS

We make the following observations about the impact, and routes to impact, of the HTA programme: it has had an impact on patients, primarily through changes in guidelines, but also directly (e.g. changing clinical practice); it has had an impact on UK health policy, through providing high-quality scientific evidence - its close relationships with the National Institute for Health and Care Excellence (NICE) and the National Screening Committee (NSC) contributed to the observed impact on health policy, although in some instances other organisations may better facilitate impact; HTA research is used outside the UK by other HTA organisations and systematic reviewers - the programme has an impact on HTA practice internationally as a leader in HTA research methods and the funding of HTA research; the work of the programme is of high academic quality - the Health Technology Assessment journal ensures that the vast majority of HTA programme-funded research is published in full, while the HTA programme still encourages publication in other peer-reviewed journals; academics agree that the programme has played an important role in building and retaining HTA research capacity in the UK; the HTA programme has played a role in increasing the focus on effectiveness and cost-effectiveness in medicine - it has also contributed to increasingly positive attitudes towards HTA research both within the research community and the NHS; and the HTA focuses resources on research that is of value to patients and the UK NHS, which would not otherwise be funded (e.g. where there is no commercial incentive to undertake research). The programme should consider the following to maintain and increase its impact: providing targeted support for dissemination, focusing resources when important results are unlikely to be implemented by other stakeholders, particularly when findings challenge vested interests; maintaining close relationships with NICE and the NSC, but also considering other potential users of HTA research; maintaining flexibility and good relationships with researchers, giving particular consideration to the Technology Assessment Report (TAR) programme and the potential for learning between TAR centres; maintaining the academic quality of the work and the focus on NHS need; considering funding research on the short-term costs of the implementation of new health technologies; improving the monitoring and evaluation of whether or not patient and public involvement influences research; improve the transparency of the priority-setting process; and continuing to monitor the impact and value of the programme to inform its future scientific and administrative development.

The effect of maneuvers for shoulder delivery on perineal trauma: a randomized controlled trial

INTRODUCTION

Approximately 85% of vaginal deliveries are accompanied by perineal trauma. The objective of this trial was to compare the incidence of perineal trauma after primary delivery of either the anterior or posterior shoulder during vaginal delivery.

MATERIAL AND METHODS

This was a randomized single-blinded trial comparing primary delivery of either the anterior or posterior shoulder in women having their first vaginal delivery. Primary outcome was any perineal trauma. Results were analyzed according to the intention-to-treat principle and supplemented with a per-protocol and as-treated analysis.

RESULTS

Between June 2013 and March 2015, 650 women were randomized, and 543 (posterior, n = 281; anterior, n = 262) were included in the final intention-to-treat analysis. Most group characteristics were similar. The frequency of any perineal trauma did not differ between the two groups (posterior: 91.5%, anterior: 90.5%; odds ratio 1.130, 95% confidence interval 0.628-2.032, p = 0.684). The results did not change after adjustment for basic characteristics with significant group differences (a1 odds ratio 1.174, 95% confidence interval 0.632-2.179, p = 0.612) or predefined risk factors (a2 odds ratio 1.139, 95% confidence interval 0.599-2.166, p = 0.691). The rate of perineal trauma also did not differ between the groups in a "per-protocol" and "as-treated" analysis.

CONCLUSIONS

There was no difference in the degree of perineal trauma after primary delivery of either the anterior or posterior shoulder. Consequently both maneuvers for shoulder delivery can be used at vaginal delivery, but further trials are warranted before certain methods can be recommended.

A retrospective study on perineal lacerations in vaginal delivery and the individual performance of experienced mifwives

BACKGROUND

Medical staff's influence on patient outcomes has become a subject of interest. We evaluated experienced midwives and compared their performance concerning perineal lacerations (PL).

METHODS

In a retrospective cohort study, 1937 women with singleton pregnancies who had delivered spontaneously with a cephalic presentation by experienced midwives in the Medical University of Vienna from January 2009 to April 2014 were included. As predictive parameters, we included basic patient-, pregnancy- and delivery-related characteristics including the individual midwife who delivered the child. The incidence of PL was the main outcome measure.

RESULTS

Overall PL and severe PL were found in 508/1937 (26.2%) and 19/1937 women (1.0%), respectively. In a multivariate analysis for PL of any degree, maternal age (ß = 0.170 ± 0.080), gestational age at delivery (ß = 0.190 ± 0.320), and birth weight (ß = 0.002 ± 0.000) significantly increased the risk, whereas multiparity (ß = -0.379 ± 0.141) and mediolateral episiotomy (ß = -1.514 ± 0.284) decreased it (p < 0.05). In addition, the individual midwife who delivered the child was a significant influencing factor, with ß-values ranging from -0.028 to 0.899 compared to the reference midwife. For severe PL, the midwife was not of significant influence.

CONCLUSIONS

The individual midwife is an independent factor that influences the risk for overall PL, not for severe PL. Other risk factors include maternal age, gestational age at delivery, birth weight, parity and episiotomy.

Interventions for women in subsequent pregnancies following obstetric anal sphincter injury to reduce the risk of recurrent injury and associated harms

BACKGROUND

Perineal damage occurs frequently during childbirth, with severe damage involving injury to the anal sphincter reported in up to 18% of vaginal births. Women who have sustained anal sphincter damage are more likely to suffer perineal pain, dyspareunia (painful sexual intercourse), defaecatory dysfunction, and urinary and faecal incontinence compared to those without damage. Interventions in a subsequent pregnancy may be beneficial in reducing the risk of further severe trauma and may reduce the risk of associated morbidities.

OBJECTIVES

To examine the effects of Interventions for women in subsequent pregnancies following obstetric anal sphincter injury for improving health.

SEARCH METHODS

We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (30 September 2014).

SELECTION CRITERIA

Randomised controlled trials, cluster-randomised trials and multi-arm trials assessing the effects of any intervention in subsequent pregnancies following obstetric anal sphincter injury to improve health. Quasi-randomised controlled trials and cross-over trials were not eligible for inclusion.

DATA COLLECTION AND ANALYSIS

No trials were included. In future updates of this review, at least two review authors will extract data and assess the risk of bias of included studies.

MAIN RESULTS

No eligible completed trials were identified. One ongoing trial was identified.

AUTHORS' CONCLUSIONS

No relevant trials were included. The effectiveness of interventions for women in subsequent pregnancies following obstetric anal sphincter injury for improving health is therefore unknown. Randomised trials to assess the relative effects of interventions are required before clear practice recommendations can be made.

The effect of primary delivery of the anterior compared with the posterior shoulder on perineal trauma: a study protocol for a randomized controlled trial

BACKGROUND

Approximately 85% of vaginal deliveries are accompanied by perineal trauma. The objective of this trial is to compare the incidence and degree of perineal trauma after primary delivery of the anterior compared with the posterior shoulder during vaginal birth. The hypothesis is that primary delivery of the posterior shoulder reduces the rate and degree of perineal trauma.

METHODS/DESIGN

This is a single-centre, randomized controlled trial, with computer-generated randomization in a 1:1 allocation ratio. Women planning their first vaginal delivery (n = 650) are randomized to primary delivery of either the anterior or posterior shoulder. The primary outcome is any perineal trauma. Additional outcomes are the perineal injury subtypes, postpartum bleeding, umbilical artery pH, Apgar score at 5 minutes and any neonatal birth trauma. Perineal trauma is assessed by a midwife or doctor blinded to the method of shoulder delivery. All midwives are trained in the two methods of shoulder delivery and in the grading of perineal tears. The trial is being undertaken at a Danish community hospital with 1,600 yearly deliveries. Data will be analyzed according to the intention-to-treat principle. Recruitment started in January 2013 and the trial is planned to proceed for 24 months.

DISCUSSION

Most delivery assistance techniques are based on tradition and heritage and lack objective evidence. This trial provides an example of how vaginal delivery techniques can be evaluated in a randomized controlled trial. The results of this trial will clarify the role that delivery of the shoulders has on perineal trauma and thereby provide knowledge to recommendations on birthing technique.

Effect of ear acupressure on acute postpartum perineal pain: a randomised controlled study

AIMS AND OBJECTIVES

To explore the effect of ear acupressure in relieving perineal pain in women during the first 48 hours after delivery.

BACKGROUND

Perineal pain is a common problem during postpartum, and different treatment modalities have been used for relief. Ear acupressure has been reported to have possible benefit on relieving acute postpartum perineal pain.

DESIGN

This study was designed as a prospective, randomised controlled trial.

METHODS

Chinese women with a singleton vertex foetus at the gestation of 37 weeks or above were recruited. One hundred and twenty six and 130 women were randomised into the intervention and control groups, respectively. Women in the intervention group received application of tapes and seeds on four designated acupressure points on both ears, while women in the control group received tapes on four irrelevant points. Both groups were instructed to stimulate the points in a similar fashion. Pain perception was assessed by the Verbal Descriptive Pain Scale and the Visual Analogue Scale, and the consumption of analgesics was also reviewed.

RESULTS

No significant difference in perineal pain perception between the groups was observed in Verbal Descriptive Pain Scale. Although the mean Visual Analogue Scale and the accumulative mean consumption of paracetamol were generally lower in the intervention group, statistical significance was not reached.

CONCLUSIONS

There is no evidence so far to conclude that ear acupressure can effectively relieve perineal pain based on the statistical results. Further research is suggested to explore whether the effectiveness of pain relief is affected by the frequency and duration of acupressure point stimulation.

RELEVANCE TO CLINICAL PRACTICE

Training of midwives to perform this intervention is easy to achieve, but further evidence is required to prove its effectiveness.

Antenatal perineal massage for reducing perineal trauma

BACKGROUND

Perineal trauma following vaginal birth can be associated with significant short-term and long-term morbidity. Antenatal perineal massage has been proposed as one method of decreasing the incidence of perineal trauma.

OBJECTIVES

To assess the effect of antenatal digital perineal massage on the incidence of perineal trauma at birth and subsequent morbidity.

SEARCH METHODS

We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (22 October 2012), the Cochrane Central Register of Controlled Trials (The Cochrane Library 2012, Issue 10), PubMed (1966 to October 2012), EMBASE (1980 to October 2012) and reference lists of relevant articles.

SELECTION CRITERIA

Randomised and quasi-randomised controlled trials evaluating any described method of antenatal digital perineal massage undertaken for at least the last four weeks of pregnancy.

DATA COLLECTION AND ANALYSIS

Both review authors independently applied the selection criteria, extracted data from the included studies and assessed study quality. We contacted study authors for additional information.

MAIN RESULTS

We included four trials (2497 women) comparing digital perineal massage with control. All were of good quality. Antenatal digital perineal massage was associated with an overall reduction in the incidence of trauma requiring suturing (four trials, 2480 women, risk ratio (RR) 0.91 (95% confidence interval (CI) 0.86 to 0.96), number needed to treat to benefit (NNTB) 15 (10 to 36)) and women practicing perineal massage were less likely to have an episiotomy (four trials, 2480 women, RR 0.84 (95% CI 0.74 to 0.95), NNTB 21 (12 to 75)). These findings were significant for women without previous vaginal birth only. No differences were seen in the incidence of first- or second-degree perineal tears or third-/fourth-degree perineal trauma. Only women who have previously birthed vaginally reported a statistically significant reduction in the incidence of pain at three months postpartum (one trial, 376 women, RR 0.45 (95% CI 0.24 to 0.87) NNTB 13 (7 to 60)). No significant differences were observed in the incidence of instrumental deliveries, sexual satisfaction, or incontinence of urine, faeces or flatus for any women who practised perineal massage compared with those who did not massage.

AUTHORS' CONCLUSIONS

Antenatal digital perineal massage reduces the likelihood of perineal trauma (mainly episiotomies) and the reporting of ongoing perineal pain, and is generally well accepted by women. As such, women should be made aware of the likely benefit of perineal massage and provided with information on how to massage.

Local cooling for relieving pain from perineal trauma sustained during childbirth

BACKGROUND

Perineal trauma is common during childbirth and may be painful. Contemporary maternity practice includes offering women numerous forms of pain relief, including the local application of cooling treatments.

OBJECTIVES

To evaluate the effectiveness and side effects of localised cooling treatments compared with no treatment, other forms of cooling treatments and non-cooling treatments.

SEARCH METHODS

We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (10 January 2012), CINAHL (1982 to 10 January 2012), the Australian New Zealand Clinical Trials Register (10 January 2012) and contacted experts in the field.

SELECTION CRITERIA

Published and unpublished randomised and quasi-randomised trials (RCTs) that compared localised cooling treatment applied to the perineum with no treatment or other treatments applied to relieve pain related to perineal trauma sustained during childbirth.

DATA COLLECTION AND ANALYSIS

At least two review authors independently assessed trials for inclusion, assessed trial quality and extracted data. A sub-set of data were double checked for accuracy. Analyses were performed on an intention-to-treat basis where data allowed. We sought additional information from the authors of three trials.

MAIN RESULTS

Ten published RCTs were included (involving 1825 women). Comparisons were local cooling treatments (ice packs, cold gel pads (with or without compression) or cold/iced baths) with no treatment, gel pads with compression, hamamelis water (witch hazel), pulsed electromagnetic energy (PET), hydrocortisone/pramoxine foam (Epifoam), oral paracetamol or warm baths. Ice packs provided improved pain relief 24 to 72 hours after birth compared with no treatment (risk ratio (RR) 0.61; 95% confidence interval (CI) 0.41 to 0.91; one study, n = 208). Women preferred the utility of the gel pads compared with ice packs or no treatment (RR 0.82; 95% CI 0.73, 0.92). Differences detected in a composite of perineal oedema and bruising and overall wound healing were noted in one small study, favouring cold gel pads (n = 37) over ice (n = 35, mean difference (MD) 0.63 on a scale of 0 to 15; 95% CI 0.20 to 1.06) or no treatment (n = 39, MD -2.10; 95% CI -3.80 to -0.40) three to 14 days after giving birth. Women reported more pain (RR 5.60; 95% CI 2.35 to 13.33; one study, 100 women) and used more additional analgesia (RR 4.00; 95% CI 1.44 to 11.13; one study, 100 women) following the application of ice packs compared with PET.

AUTHORS' CONCLUSIONS

There is only limited evidence to support the effectiveness of local cooling treatments (ice packs, cold gel pads, cold/iced baths) applied to the perineum following childbirth to relieve pain.

Surgical repair of spontaneous perineal tears that occur during childbirth versus no intervention

BACKGROUND

Perineal tears commonly occur during childbirth. They are sutured most of the time. Surgical repair can be associated with adverse outcomes, such as pain, discomfort and interference with normal activities during puerperium and possibly breastfeeding. Surgical repair also has an impact on clinical workload and human and financial resources.

OBJECTIVES

To assess the evidence for surgical versus non-surgical management of first- and second-degree perineal tears sustained during childbirth.

SEARCH STRATEGY

We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (1 May 2011), CENTRAL (The Cochrane Library 2011, Issue 2 of 4) and MEDLINE (Jan 1966 to 2 May 2011). We also searched the reference lists of reviews, guidelines and other publications and contacted authors of identified eligible trials.

SELECTION CRITERIA

Randomised controlled trials (RCTs) investigating the effect on clinical outcomes of suturing versus non-suturing techniques to repair first- and second-degree perineal tears sustained during childbirth.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed trials for inclusion and assessed trial quality. Three review authors independently extracted data.

MAIN RESULTS

We included two RCTs (involving 154 women) with a low risk of bias. It was not possible to pool the available studies. The two studies do not consistently report outcomes defined in the review. However, no significant differences were observed between the two groups (surgical versus non-surgical repair) in incidence of pain and wound complications, self-evaluated measures of pain at hospital discharge and postpartum and re-initiation of sexual activity. Differences in the use of analgesia varied between the studies, being high in the sutured group in one study. The other trial showed differences in wound closure and poor wound approximation in the non-suturing group, but noted incidentally also that more women were breastfeeding in this group.

AUTHORS' CONCLUSIONS

There is limited evidence available from RCTs to guide the choice between surgical or non-surgical repair of first- or second-degree perineal tears sustained during childbirth. Two studies find no difference between the two types of management with regard to clinical outcomes up to eight weeks postpartum. Therefore, at present there is insufficient evidence to suggest that one method is superior to the other with regard to healing and recovery in the early or late postnatal periods. Until further evidence becomes available, clinicians' decisions whether to suture or not can be based on their clinical judgement and the women's preference after informing them about the lack of long-term outcomes and the possible chance of a slower wound healing process, but possible better overall feeling of well being if left un-sutured.

PErineal Assessment and Repair Longitudinal Study (PEARLS): protocol for a matched pair cluster trial

Background

The Perineal Assessment and Repair Longitudinal Study (PEARLS) is a national clinical quality improvement initiative designed to improve the assessment and management of perineal trauma. Perineal trauma affects around 85% of women who have a vaginal birth in the UK each year and millions more world-wide. Continuous suturing techniques compared with traditional interrupted methods are more effective in reducing pain and postnatal morbidity, however they are not widely used by clinicians despite recommendations of evidence based national clinical guidelines. Perineal suturing skills and postnatal management of trauma remain highly variable within and between maternity units in the UK as well as worldwide. Implementation of a standardised training package to support effective perineal management practices could reduce perineal pain and other related postnatal morbidity for a substantial number of women.

Methods/Design

PEARLS is a matched pair cluster trial, which is being conducted in maternity units across the UK. Units within a matched pair will be randomised to implement the study intervention either early or late in the study period. The intervention will include the cascading of a multi-professional training package to enhance midwifery and obstetric skills in the assessment, repair and postnatal management of perineal trauma. Women who have had an episiotomy or second degree perineal tear will be eligible for recruitment. Prior to developing the intervention and deciding on study outcomes, a Delphi survey and a consensus conference were held to identify what women, who previously suffered perineal trauma during childbirth, considered to be important outcomes for them. Findings from this preliminary work (which will be reported elsewhere) and other outcomes including women's experiences of perineal pain and pain on activity, breastfeeding uptake and duration and psychological well-being as assessed using the Edinburgh Postnatal Depression Scale (EPDS) will be assessed at 10 days and three months post-birth.

Discussion

Implementation of evidence-based perineal assessment and management practices, could lead to significantly improved physical and psychological health outcomes for women in the UK and world-wide.

Trial registration

PEARLS is registered with the Current Controlled Trials Registry (no: ISRCTN28960026). NIHR UKCRN portfolio no: 4785.

Postpartum perineal pain in a low episiotomy setting: association with severity of genital trauma, labor care, and birth variables

BACKGROUND

Perineal pain is common after childbirth. We studied the effect of genital tract trauma, labor care, and birth variables on the incidence of pain in a population of healthy women exposed to low rates of episiotomy and operative vaginal delivery.

METHODS

A prospective study of genital trauma at birth and assessment of postpartum perineal pain and analgesic use was conducted in 565 midwifery patients. Perineal pain was assessed using the present pain intensity (PPI) and visual analog scale (VAS) components of the validated short-form McGill pain scale. Multivariate logistic regression examined which patient characteristics or labor care measures were significant determinants of perineal pain and use of analgesic medicines.

RESULTS

At hospital discharge, women with major trauma reported higher VAS pain scores (2.16 +/- 1.61 vs 1.48 +/- 1.40; p < 0.001) and were more likely to use analgesic medicines (76.3 vs 23.7%, p = 0.002) than women with minor or no trauma. By 3 months, average VAS scores were low in each group and not significantly different. Perineal pain at the time of discharge was associated in univariate analysis with higher education level, ethnicity (non-Hispanic white), nulliparity, and longer length of active maternal pushing efforts. In a multivariate model, only trauma group and length of active pushing predicted the pain at hospital discharge. In women with minor or no trauma, only length of the active part of second stage labor had a positive relationship with pain. In women with major trauma, the length of active second stage labor had no independent effect on the level of pain at discharge beyond its effect on the incidence of major trauma.

CONCLUSIONS

Women with spontaneous perineal trauma reported very low rates of postpartum perineal pain. Women with major trauma reported increased perineal pain compared with women who had no or minor trauma; however, by 3 months postpartum this difference was no longer present. In women with minor or no perineal trauma, a longer period of active pushing was associated with increased perineal pain.
