Long-Term Sexual Function After Obstetric Anal Sphincter Injuries:

Sexual Function in Women at 6 and 12 Months After Obstetric Anal Sphincter Injury: Is Pelvic Floor Physical Therapy Associated With Improved Outcomes?

IMPORTANCE

Women with obstetric anal sphincter injury (OASI) are at increased risk of postpartum sexual dysfunction. Risk persists beyond 3 years after perineal trauma in up to half of patients with OASI.

OBJECTIVES

The aims of this study were to determine if postpartum pelvic floor physical therapy (PFPT) is associated with improved sexual function after vaginal delivery with OASI and to describe sexual function in patients with OASI at 6 and 12 months postpartum.

STUDY DESIGN

This is a retrospective cohort study of patients with OASI. Women were grouped according to PFPT attendance. The Postpartum Pelvic Floor and Birth Questionnaire (PPFBQ), which compares current sexual function to baseline prepregnancy sexual function, and the Female Sexual Function Index (FSFI) were administered at 6 and 12 months, respectively, to evaluate postpartum sexual function.

RESULTS

Two hundred women were included. Sixty-four (32%) women attended PFPT; 136 (68%) did not attend PFPT. Patients reported worse-than-baseline sexual function at 6 months postpartum in the PPFBQ sexual activity domain, but the PFPT group had lower median score than the non-PFPT group (2.3 [2.0, 2.8] vs 2.7 [2.1, 3.1], P = 0.034), with scores <3.0 indicating worse-than-baseline functioning. The FSFI composite scores were similar between groups and showed 80.7% of the patients with OASI meeting the criteria for female sexual dysfunction at 12 months postpartum. Attendance of PFPT was not significantly associated with composite FSFI scores and most domains of PPFBQ.

CONCLUSIONS

Attendance of PFPT did not significantly impact overall sexual function in OASI patients at 6 and 12 months postpartum. Sexual function is complex and may be more effectively addressed in the postpartum period using a multidimensional approach.

Incidence and risk factors for secondary failure after acute obstetric sphincter injury repair - an audit of 239 women

AIM

The rate of secondary failure after obstetric sphincter injury repair is unknown, with the literature reporting rates ranging from 0.1% to 53%. We aimed to perform an audit to identify the rate and risk factors for failure of sphincter repair in a cohort of postpartum women using endoanal ultrasound (EAUS) and manometry, assessing the risk factors and impact of these events.

METHOD

Prospective data were collected within a 2 year period from patients who attended the perineal clinic at Eastern Health. Variables of primary repair and presence of postpartum complications were recorded and subsequently analysed.

RESULTS

Of 239 patients with obstetric anal sphincter injury (OASI) included, 100 (41.8%) had EUAS evidence of sphincter defects. Only 20% with secondary repair failure were symptomatic with faecal or flatal incontinence at a mean follow-up of 23.4 months postpartum. Patients with secondary repair failure had lower anal resting (p = 0.006) and maximum squeeze pressures compared with patients with intact repairs (p < 0.001). In terms of variables that were investigated, namely location, operator hierarchy, type of repair and material used, none had a statistically significant correlation with secondary repair failure of OASI. Postpartum complications had an overall incidence of 12.7%, and those with any complication were found to have an increased rate of secondary failure of repair (p = 0.157).

CONCLUSION

Using EAUS to confirm secondary failure of repair, incidence was 41.4% in this cohort. There were no identifiable modifiable variables that reduced the risk of secondary failure of repair. Further prospective research with increased sample size and longer follow-up periods is required to assess the validity of the findings.

Perinatal mortality and neonatal and maternal outcome per gestational week in term pregnancies: A registry-based study

INTRODUCTION

Human pregnancy is considered term from 37+0/7 to 41+6/7 weeks. Within this range, both maternal, fetal and neonatal risks may vary considerably. This study investigates how gestational age per week is related to the components of perinatal mortality and parameters of adverse neonatal and maternal outcome at term.

MATERIAL AND METHODS

A registry-based study was made of all singleton term pregnancies in the Netherlands from January 2014 to December 2017. Stillbirth and early neonatal mortality, as components of perinatal mortality, were defined as primary outcomes; adverse neonatal and maternal events as secondary outcomes. Neonatal adverse outcomes included birth trauma, 5-minute Apgar score ≤3, asphyxia, respiratory insufficiency, neonatal intensive care unit admission and composite neonatal outcome. Maternal adverse outcomes included instrumental vaginal birth, emergency cesarean section, obstetric anal sphincter injury, postpartum hemorrhage, hypertensive disorders of pregnancy and composite maternal outcome. The primary outcomes were evaluated by comparing weekly prospective risks of stillbirth and neonatal death using a fetuses-at-risk approach. Secondly, odds ratios (OR) for perinatal mortality, adverse neonatal and maternal outcome using a births-based approach were compared for each gestational week with all births occurring after that week.

RESULTS

Data of 581 443 births were analyzed. At 37, 38, 39, 40, 41 and 42 weeks, the respective weekly prospective risks of stillbirth were 0.015%, 0.022%, 0.031%, 0.036%, 0.069% and 0.081%; the respective weekly prospective risks of early neonatal death were 0.051%, 0.047%, 0.032%, 0.031%, 0.039% and 0.035%. The OR for adverse neonatal outcomes were the lowest at 39 and 40 weeks. The OR for adverse maternal outcomes, including operative birth, continuously increased with each gestational week.

CONCLUSIONS

The prospective risk of early neonatal death for babies born at 39 weeks is lower than the risk of stillbirth in pregnancies continuing beyond 39+6/7 weeks. Birth at 39 weeks was associated with the best combined neonatal and maternal outcome, fewer operative births and fewer maternal and neonatal adverse outcomes compared with pregnancies continuing beyond 39 weeks. This information with appropriate perspectives should be included when counseling term pregnant women.

Comparison of perineal outcomes in Chinese women adopting lateral positions and lithotomy positions during the passive and active phases of the second stage of labour: An observational study

AIMS

To compare the effects of the adoption of lateral positions and lithotomy positions during the passive and active phases of the second stage of labour on perineal outcomes.

DESIGN

An observational study with prospectively collected data, conducted in three hospitals in China.

METHOD

Attending midwives recorded the perineal outcomes and characteristics of women giving birth between July-November 2020. Binary logistic regression was performed to explore the effects of lateral positions on perineal outcomes during different phases of the second stage of labour. The STROBE guidelines guided the reporting of this study.

RESULTS

Among primiparous women, when compared with those who adopted lateral positions during the passive phase of the second stage of labour and changed to lithotomy positions during the active phase, women who assumed lateral positions during both the passive and active phases had a higher rate of intact perineum/first-degree perineal tears and a reduced risk of episiotomy, and episiotomy/second-degree perineal tears. No significant difference was found in perineal outcomes between those who assumed lithotomy positions during the passive and active phases and those who adopted lateral positions during the passive phase and changed to lithotomy positions during the active phase. No significant difference was found in perineal outcomes among multiparous women, regardless of different positions adopted at the passive and/or the active phase.

CONCLUSION

Lateral positions during the active phase may have protective effects on the perineum in primiparous women. However, adopting lateral positions only during the passive phase did not promote better perineal outcomes, regardless of parity.

RELEVANCE TO CLINICAL PRACTICE

This study will provide a further reference for the use of lateral positions during different phases of the second stage of labour among primiparous and multiparous women in clinical practice, contributing to the perineal protection during childbirth.

Women's experience of obstetric anal sphincter injury following childbirth: An integrated review

BACKGROUND

Perineal injury during childbirth is a very common event which affect women during childbirth. Significant morbidities are associated with third-and-fourth degree perineal tears in particular, also referred to as obstetric anal sphincter injuries (OASIS). With an increasing global birth rate and rising interventions in birth, the incidence of perineal trauma following vaginal birth is increasing on an international scale, impacted also by more accurate classification and definitions of OASIS and increased pre-existing co morbidities amongst affected women. The consequences of OASIS can be physically and psychologically distressing for affected women and have significant impact on quality of life.

METHODOLOGY

The aim of this integrative review was to examine women's experience of OASIS following childbirth using a systematic approach. This is presented in a five-stage process that includes problem identification, literature search, data extraction and evaluation, data analysis and presentation of results. A number of academic electronic databases were systematically searched and results are presented and analysed. Results of the complete search are presented in PRISMA format. Eight papers, which were assessed for quality using an appropriate appraisal tool, are included in the review and thematic analysis used to identify themes.

FINDINGS

The themes identified were; psychological consequences, the role of the health care professionals and implications for future pregnancies. Psychological consequences included anxiety, loneliness, isolation, shame, fear, many of which were associated with physical ramifications of OASIS and how these feelings affect activities of daily living. The importance of access to and support from health care professionals was highlighted. The impact the experience of OASIS had on women's decisions about future pregnancies was also evident.

CONCLUSION

The association between OASIS and maternal quality of life following childbirth can be substantial as evidenced by this literature review. The review identifies the need for improvement in the care and management of these women to alleviate the physical and psychological consequences of OASIS, including decisions in relation to future pregnancies and childbirth. Health care professionals caring for women in pregnancy and childbirth need to be educated and informed on the sequelae of OASIS, to ensure appropriate information and support is provided to these women and their families. Such knowledge may enable health care professionals to alleviate symptoms associated with OASIS and help women make sense and cope with their experiences.

"Struggling to settle with a damaged body" - A Swedish qualitative study of women's experiences one year after obstetric anal sphincter muscle injury (OASIS) at childbirth

OBJECTIVE

This study aimed to explore women's experiences related to recovery from obstetric anal sphincter muscle injuries (OASIS) one year after childbirth.

METHOD

This is a qualitative study based on written responses from 625 women approximately one year after childbirth in which OASIS occurred. Data was obtained from a questionnaire distributed by the national Perineal Laceration Register (PLR) in Sweden. Inductive qualitative content analysis was applied for analysis.

RESULTS

The theme "Struggling to settle with a damaged body" indicated that the first year after OASIS involved a struggle to settle to and accept living with a changed and sometimes still-wounded body. Many participants described problems related to a non-functional sexual life, physical and psychological problems that left them feeling used and broken, and increased worries for their future health and pregnancies. However, some women had adjusted to their situation, had moved on with their lives, and felt recovered and strong. Encountering a supportive and helpful health care professional was emphasized as vital for recovery after OASIS.

CONCLUSION

This study provides important insights on how women experience their recovery approximately one year after having had OASIS at childbirth, wherein many women still struggled to settle into their damaged bodies. Clear pathways are needed within health care organizations to appropriate health care services that address both physical and psychological health problems of women with prolonged recovery after OASIS.
