Perineal pain the first year after childbirth and uptake of post-partum check-up- A Swedish cohort study

The severity of second-degree perineal tears and dyspareunia during one year postpartum: A prospective cohort study

INTRODUCTION

Childbirth-related injuries of the pelvic floor may impact women's sexual health with symptoms such as dyspareunia. A better understanding of dyspareunia based on tissue trauma severity in second-degree tears is needed. The primary aim of this study was to assess differences in dyspareunia according to the severity of perineal tears, with a focus on subcategories of second-degree tears at three and twelve months postpartum. The secondary aim was to assess the time to resumption of intercourse after birth according to the severity of second-degree tears.

MATERIAL AND METHODS

This single-center observational cohort study was conducted between January 2021 and July 2022. Women meeting the inclusion criteria were included during pregnancy. After birth, all perineal tears were classified according to RCOG recommendation, and second-degree tears were further subcategorized based on the percentage of damage to the perineum (2A, 2B, 2C). Dyspareunia and time to resumption of intercourse were collected through an electronic questionnaire at three and twelve months postpartum.

RESULTS

Our study included 857 women; of them, 51.6% (n = 442) were primipara and 48.4% (n = 415) were multipara. The percentages of women reporting dyspareunia according to the degree of the tear at three months postpartum were as follows: no tear/first-degree tear 60%, 2A-tear 60%, 2B-tear 52%, 2C-tear 77%, and episiotomy 77%; and at twelve months postpartum: no tear/first-degree tear 52%, 2A-tear 50%, 2B-tear 40%, 2C-tear 69%, and episiotomy 64%. When comparing dyspareunia between the no tear/first-degree tear category and the second-degree subcategories, no statistically significant differences were found. Women in all second-degree subcategories resumed intercourse approximately 4.8 months postpartum, compared to 3.8 months postpartum for those with no tear or first-degree tear (p < 0.05).

CONCLUSIONS

There was no statistically significant association between the severity of second-degree tears and dyspareunia. The proportion of women reporting dyspareunia is noticeable for all perineal tear categories, with the highest rate among women with the most severe second-degree perineal tear. Women in all second-degree subcategories resumed intercourse approximately one month later than those with no tear or first-degree tear.

Subclassification of second-degree tears at delivery: creation and reported outcomes

BACKGROUND

Perineal tears at delivery are common. The current WHO classification system compacts all the varying extents of second-degree tears into one code. Some tears lead to long-term injuries. The correct identification and classification of disease is necessary for correct clinical management as well as for research. Regulatory standards govern care practices. This article describes the process of creating and testing new subclassifications for second-degree tears at delivery.

METHODS

The development and implementation of new subclassifications of second-degree perineal tears after delivery in Sweden are described. The new classification was tested for incidence and relevance via the national perineal laceration register (PLR) in 11,203 women with prospectively recorded second degree tears.

RESULTS

Second-degree tears after delivery are subdivided into four subgroups according to the anovaginal distance and the extent in length and depth of the largest perineal/vaginal tear, which can be combined with uni-or bilateral levator ani avulsion. Women with larger second-degree tears were more likely than women with smaller tears to report complications after eight weeks (OR 1.41 CI 1.21-1.64, p < 0.001) and one year (OR 1.27, CI 1.1-1.46, p < 0.001).

CONCLUSION

Detailed subclassifications of perineal and vaginal tears are implemented in the Swedish ICD-10 coding system and Swedish national registers. The outcomes after second-degree tears differ according to their extent, which corroborates the classification rationale. These subclassifications can be used in studies of preventive measures, treatment and patient-reported outcomes and experiences taking into account the extent of second-degree perineal tears at delivery.

TRIAL REGISTRATION

Data regarding women were prospectively collected from the National perineal laceration register (PLR) from January 1, 2021, to December 31, 2022.

The effect of postpartum interventions on healing and pain in women with perineal trauma: A systematic review and meta-analysis

INTRODUCTION

Interventions aimed at perineal healing and pain relief can have a positive impact on postpartum experiences in women who experience perineal trauma during childbirth.

OBJECTIVE

The aim of this systematic review and meta-analysis was to compare various methods applied for healing and pain relief from perineal trauma based on primary studies.

METHODS

The study protocol was developed following PRISMA guidelines, and Meta-Analyses guidelines. Searches were conducted between March and April 2024. Registration was completed using PROSPERO. Searches were performed using PubMed, the Cochrane Library, EBSCO, Embase, Web of Science, PsycINFO, Scopus, National Thesis Center, TR Dizin, Türkiye Klinikleri, and DergiPark Academic search engines. The methodological quality of the studies was assessed using the RoB-1 and RoB-2. Data were aggregated through meta-analysis, and a GRADE evidence profile was created.

RESULTS

Nineteen studies involving 1899 participants were included in the meta-analysis. The results showed that interventions performed within the first 24 h after episiotomy did not reduce pain. However, the effects of the interventions were observed on the second day, with cold application identified as the most effective method. Additionally, interventions did not affect healing during the first three days, but a more pronounced improvement was noted in the intervention group by the fifth day. Healing began around the 7th-10th days even without intervention. The REEDA (redness, edema, ecchymosis, discharge, and approximation) score decreased most significantly in the group that received perineal education (diet, Kegel exercise, infection symptoms, and perineal hygiene).

CONCLUSION

Cold application is recommended on the second day to reduce pain following perineal trauma. Interventions were found to accelerate the healing process by initiating healing at least two days earlier, with perineal education being the most effective method. However, further research on topical herbal treatments and perineal hygiene education is needed to strengthen this evidence.

Postpartum perineal pain and its association with sub-classified second-degree tears and perineal trauma-A follow-up of a randomized controlled trial

INTRODUCTION

Postnatal perineal pain is prevalent following childbirth and can impact women both physically and emotionally. The aim of the study was to study the effect of collegial midwifery assistance on perineal pain and pain medication 1 month after birth and to investigate the associations between the type of tear and perineal pain, satisfaction with healing, and resumption of intercourse.

MATERIAL AND METHODS

A follow-up questionnaire was sent 1 month postpartum to women with a first spontaneous vaginal birth participating in a randomized controlled trial (Oneplus trial). Data were collected from December 2019 to May 2020. Differences in perineal pain between women attended by one or two midwives were analyzed according to intention-to-treat using bivariate analyses. Associations between the type of tear and perineal pain, satisfaction with healing, and resumption of sexual intercourse were investigated using univariable and multivariable logistic regression. The category no tear/first-degree tear was compared separately to each of the other tear categories.

TRIAL REGISTRATION NUMBER

ClinicalTrials.gov, NCT03770962.

RESULTS

Out of 2233 women, 1762 responded within 30-60 days postpartum. Of women in the no tear/first-degree tear category, 27.7% reported perineal pain during the past week, in contrast to women with OASI, where 64.2% reported perineal pain. Women with OASI experienced the highest odds of perineal pain (aOR 4.51, 95% CI 2.72-7.47) compared to those with no tear/first-degree tear, followed by women with major second-degree tears (aOR 1.87, 95% CI 1.45-2.41), women with an episiotomy (aOR 1.78, 95% CI 1.11-2.87), and those with minor second-degree tears (aOR 1.43, 95% CI 1.06-1.94). Women with episiotomy reported the highest odds ratios for dissatisfaction with tear healing (aOR 3.48, 95% CI 1.92-6.31). No significant differences in perineal pain and pain medication were observed between women allocated to collegial midwifery assistance and those allocated to standard care.

CONCLUSIONS

Women with OASI reported the highest odds of perineal pain 30-60 days after birth compared to women with no tear or first-degree tear, followed by women with major second-degree tears. Women subjected to an episiotomy reported highest odds ratios of dissatisfaction with tear healing.

Occurrence and risk factors for second-degree perineal tears: A prospective cohort study using a detailed classification system

BACKGROUND

The amount of tissue trauma within second-degree perineal tears varies widely. Therefore, subcategorization of second-degree tears and a better understanding of their occurrence and risk factors are needed. The aim of this study was to assess the occurrence of perineal tears when second-degree tears were subcategorized. Furthermore, we aimed to assess the association between variables related to perineal anatomy and other potential risk factors, with second-degree tear subcategories.

METHODS

This prospective cohort study included 880 primiparous and multiparous women giving birth to one child vaginally. Perineal tears were categorized using the classification system recommended by the Royal College of Obstetricians and Gynaecologists. In addition, second-degree tears were subcategorized as 2A, 2B, or 2C according to the percentage of damage to the perineal body. Selected variables related to perineal anatomy were as follows: length of genital hiatus; perineal body length; and previous perineal trauma. Risk factors for second-degree tear subcategories were analyzed using a multinominal regression model.

RESULTS

Perineal tears occurred as follows: first-degree: 35.6% (n = 313), 2A: 16.3% (n = 143), 2B: 9.1% (n = 80), 2C: 6.6% (n = 58), and third- or fourth-degree: 1.6% (n = 14). In total, 169/880 participants underwent an episiotomy. When episiotomies were excluded, the risk for 2B, or 2C tears increased with smaller genital hiatus, larger perineal body, previous perineal trauma, primiparity, higher gestational age, instrumental vaginal delivery and fetal presentation other than occiput anterior.

CONCLUSION

The occurrence of second-degree tear subcategories was 16.3% for 2A tears, 9.1% for 2B tears, and 6.6% for 2C tears. Factors related to perineal anatomy increased the odds for experiencing a second-degree tear in a more severe subcategory.

Pelvic floor symptoms according to the severity of second-degree perineal tears within 12 months post-partum: A longitudinal prospective cohort study

INTRODUCTION

Second-degree perineal tears following vaginal birth are common and presumed to be of little clinical importance. However, the extent of damage to the perineal body varies widely, and there is reason to believe that larger second-degree tears may be associated with more pelvic floor symptoms, compared to lesser form. Therefore, the aim of this study was to assess differences in pelvic floor symptoms according to the severity of second-degree perineal tears up to 12 months post-partum, stratified by parity.

MATERIAL AND METHODS

This was a prospective cohort study conducted at Akershus University Hospital, a tertiary referral hospital in Norway. The study sample consisted of 409 primiparas and 394 multiparas with vaginal births. Perineal tears were classified using the classification system recommended by the Royal College of Obstetricians and Gynecologists. Further, second-degree tears were subclassified as 2A, 2B, or 2C, depending on the percentage of damage to the perineal body. Episiotomies were analyzed as a separate group. Pelvic floor symptoms were assessed using the Karolinska Symptoms After Perineal Tear Inventory (KAPTAIN). A linear mixed model was estimated to assess the trend in pelvic floor symptom scores according to perineal tear category and stratified by parity. The primary and secondary outcome measures were the mean sum scores of the KAPTAIN-Inventory, measured in pregnancy (at 18 weeks of gestation), at 3- and 12 months post-partum, and the reported impact of genital discomfort on quality of life measured in pregnancy and at 12 months post-partum.

RESULTS

There were no significant differences in pelvic floor symptom scores over time, or at any timepoint, between no tear, first-degree tear, or second-degree tear subcategories, for primi-, and multiparas. Pelvic floor symptoms increased from pregnancy to 3 months post-partum and remained higher at 12 months post-partum compared to pregnancy in all perineal tear categories. Compared to primiparas, multiparas reported a significantly higher impact of genital discomfort on quality of life in pregnancy and at 12 months post-partum.

CONCLUSIONS

There were no statistically significant differences in pelvic floor symptoms according to the severity of second-degree perineal tears.

The severity of second-degree perineal tears and perineal pain during three months postpartum: A prospective cohort study

BACKGROUND

Second-degree perineal tears are common and can vary widely in the extent of tissue trauma. Therefore, a better understanding of perineal pain based on tissue trauma severity in second-degree tears is needed.

AIM

The primary aim of this study was to assess differences in perineal pain according to the severity of perineal tears, with a focus on subcategories of second-degree tears, during the first three months postpartum. The secondary aim was to assess the use of pain medication and breastfeeding patterns according to the severity of the second-degree tears.

METHODS

In this observational cohort study, nulli- and multiparous women with singleton pregnancies were included during pregnancy. After birth, perineal tears were classified using the latest international classification system. In addition, second-degree tears were subcategorised according to percentage of damage to the perineum (<50 %=2A,>50 % but less than entire perineum=2B, affecting entire perineum, anal sphincter not involved=2C). Perineal pain, use of pain medication and breastfeeding patterns were assessed during a phone interview seven to ten days postpartum and through an electronic questionnaire three months postpartum.

FINDINGS

Out of 880 vaginal births, 852 participants completed the phone interview and 715 answered the electronic questionnaire. During the first three months postpartum, women with 2C-tears reported statistically significantly higher pain scores and more frequent use of pain medication compared to women with 2A-tears. There was no statistically significant difference between the number of participants not breastfeeding between second-degree tear subcategories.

CONCLUSION

Women with 2C-tears reported higher perineal pain scores and more use of pain medication compared to those with less severe tears during three months postpartum.

Effects of Perineal Warm Compresses during the Second Stage of Labor on Reducing Perineal Trauma and Relieving Postpartum Perineal Pain in Primiparous Women: A Systematic Review and Meta-Analyses

Non-pharmaceutical midwifery techniques, including perineal warm compresses, to improve maternal outcomes remain controversial. The aims of this study are to assess the effects of perineal warm compresses on reducing perineal trauma and postpartum perineal pain relief. This systematic review included randomized controlled trials (RCTs). We searched seven bibliographic databases, three RCT register websites, and two dissertation databases for publications from inception to 15 March 2023. Chinese and English publications were included. Two independent reviewers conducted the risk of bias assessment, data extraction, and the evaluation of the certainty of the evidence utilizing the Cochrane risk of bias 2.0 assessment criteria, the Review Manager 5.4, and the online GRADEpro tool, respectively. Seven RCTs involving 1362 primiparous women were included. The combined results demonstrated a statistically significant reduction in the second-, third- and/or fourth- degree perineal lacerations, the incidence of episiotomy, and the relief of the short-term perineal pain postpartum (within two days). There was a potential favorable effect on improving the integrity of the perineum. However, the results did not show a statistically significant supportive effect on reducing first-degree perineal lacerations and the rate of perineal lacerations requiring sutures. In summary, perineal warm compresses effectively reduced the second-, third-/or fourth-degree perineal trauma and decreased the short-term perineal pain after birth.

"The ignored pain" - experiences of encounters with healthcare from the perspective of women with pain persisting after childbirth - a qualitative study

INTRODUCTION

Although the prevalence of pain persisting after pregnancy or labour decreases with time, up to 35 % of women report pain 8 months to 12 years after childbirth. To prevent the development and reduce the impact of chronic pain, researchers and clinicians emphasize the importance of early diagnosis as well as timely and appropriate treatment. Previous studies have shown that when women with post-childbirth morbidities consult healthcare professionals during the first year following birth, their problems are often neglected, and they do not receive adequate treatment.

OBJECTIVE

To explore how women with pain persisting for eight months after childbirth experienced encounters with healthcare.

METHODS

A descriptive qualitative design with 20 face-to-face, semi-structured interviews. Data were analysed using inductive qualitative content analysis.

RESULTS

"Pain ignored by healthcare" was identified as an essential theme and included four categories: "Questioned pain experience," "Inadequate pain management," "Lost in healthcare," and "Insufficient postpartum care " CONCLUSION: The women experienced that their pain was often not recognized or adequately treated, but instead ignored or trivialized. Recurring were descriptions of experienced knowledge gaps among the healthcare providers regarding pain and its management. There was an overall desire among women for a well-defined and well-functioning chain of care with better accessibility and scope.

The Utility of CO2 Laser Treatment of Pelvic Symptoms in Women with Previous Perineal Trauma during Delivery

This study aimed to examine the impact of fractional CO2 laser treatment of pelvic symptoms in women who have undergone perineal trauma from vaginal delivery. It was a retrospective, monocentric analysis that encompassed all women assessed for pelvic discomfort or signs of vulvovaginal atrophy following vaginal delivery between 2013 and 2018. The severity of symptoms was assessed using the Visual Analogue Scale (VAS). Twenty-seven patients met the inclusion criteria and were sorted into two groups: (1) women who had undergone episiotomies during labor (n = 11); and (2) women who had experienced spontaneous tears during vaginal delivery (n = 16). For women with episiotomies, each treatment and subsequent evaluation consistently showed a significant reduction in dyspareunia intensity. A similar positive trend was observed regarding pain at the introitus (7.5 vs. 6.5 after the first treatment, p = 0.03; 6.5 vs. 3 after the second treatment, p = 0.01; 3 vs. 1 after the third treatment, p = 0.01). Among women experiencing spontaneous perineal tears during delivery, there was a notable decrease in dyspareunia following all treatments (8 vs. 7 after the first treatment, p = 0.01; 8 vs. 4 after the second treatment, p = 0.02; 3 vs. 1 after the third treatment, p = 0.03). The impact of laser treatment did not exhibit significant differences between women who underwent episiotomies and those who experienced spontaneous perineal tears. In conclusion, fractional CO2 laser can be regarded as a non-pharmacological option for managing pelvic floor symptoms in women who encountered perineal trauma during delivery, independently from the nature, spontaneity, or iatrogenesis of the perineal laceration.

Moderate or intensive management of the active phase of second-stage labor and risk of urinary and anal incontinence: results of the PASST randomized controlled trial

BACKGROUND

Incontinence occurs frequently in the postpartum period. Several theoretical pathophysiological models may underlie the hypothesis that different types of management of the active phase of the second stage of labor have different effects on pelvic floor muscles and thus perhaps affect urinary and anal continence.

OBJECTIVE

This study aimed to evaluate the impact of "moderate pushing" on the occurrence of urinary or anal incontinence compared with "intensive pushing," and to determine the factors associated with incontinence at 6 months postpartum.

STUDY DESIGN

This was a planned analysis of secondary objectives of the PASST (Phase Active du Second STade) trial, a multicenter randomized controlled trial. PASST included nulliparous women with singleton term pregnancies and epidural analgesia, who were randomly assigned at 8 cm of dilatation to either the intervention group that used "moderate" pushing (pushing only twice during each contraction, resting regularly for 1 contraction in 5 without pushing, and no time limit on pushing) or the control group following the usual management of "intensive" pushing (pushing 3 times during each contraction, with no contractions without pushing, with an obstetrician called to discuss operative delivery after 30 minutes of pushing). Data about continence were collected with validated self-assessment questionnaires at 6 months postpartum. Urinary incontinence was defined by an ICIQ-UI SF (International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form) score ≥1 and anal incontinence by a Wexner score ≥2. A separate analysis was also performed among the more severely affected women (ICIQ-UI SF ≥6 and Wexner ≥5). Factors associated with incontinence were assessed with univariate and multivariable analyses.

RESULTS

Among 1618 women initially randomized, 890 (55%) returned the complete questionnaire at 6 months. The rate of urinary incontinence was 36.6% in the "moderate" pushing group vs 38.5% in the "intensive" pushing group (relative risk, 0.95; 95% confidence interval, 0.80-1.13), whereas the rate of anal incontinence was 32.2% vs 34.6% (relative risk, 0.93; 95% confidence interval, 0.77-1.12). None of the obstetrical factors studied related to the second stage of labor influenced the occurrence of urinary or anal incontinence, except operative vaginal delivery, which increased the risk of anal incontinence (adjusted odds ratio, 1.50; 95% confidence interval, 1.04-2.15).

CONCLUSION

The results of the PASST trial indicate that neither moderate nor intensive pushing efforts affect the risk of urinary or anal incontinence at 6 months postpartum among women who gave birth under epidural analgesia.

Sonographic postpartum anal sphincter defects and the association with pelvic floor pain and dyspareunia

INTRODUCTION

Pelvic floor pain and dyspareunia are both important entities of postpartum pelvic pain, often concomitant and associated with perineal tears during vaginal delivery. The association between postpartum sonographic anal sphincter defects, pelvic floor pain, and dyspareunia has not been fully established. We aimed to determine the prevalence of postpartum anal sphincter defects using three-dimensional endoanal ultrasonography (3D-EAUS) and evaluate their association with symptoms of pelvic floor pain and dyspareunia.

MATERIAL AND METHODS

This prospective cohort study followed 239 primiparas from birth to 12 months post delivery. Anal sphincters were assessed with 3D-EAUS 3 months postpartum, and self-reported pelvic floor function data were obtained using a web-based questionnaire distributed 1 year after delivery. Descriptive statistics were compared between the patients with and without sonographic defects, and the association between sonographic sphincter defects and outcomes were analyzed using logistic regression.

RESULTS

At 3 months postpartum, 48/239 (20%) patients had anal sphincter defects on 3D-EAUS, of which 43 (18%) were not clinically diagnosed with obstetric anal sphincter injury at the time of delivery. Patients with sonographic defects had higher fetal weight than those without defects, and a perineum <2 cm before the suture was a risk factor for defects (odds ratio [OR], 6.9). Patients with sonographic defects had a higher frequency of dyspareunia (OR, 2.4), and pelvic floor pain (OR, 2.3) than those without defects.

CONCLUSIONS

Our results suggest an association between postpartum sonographic anal sphincter defects, pelvic floor pain, and dyspareunia. A perineal height <2 cm, measured by bidigital palpation immediately postdelivery, was a risk factor for sonographic anal sphincter defect. We suggest offering pelvic floor sonography around 3 months postpartum to high- risk women to optimize diagnosis and treatment of perineal tears and include perineum <2 cm prior to primary repair as a proposed indication for postpartum follow-up sonography.

Use of surgical glue versus suture to repair perineal tears: a randomised controlled trial

BACKGROUND

Surgical glue has been used in several body tissues, including perineal repair, and can benefit women.

OBJECTIVES

To evaluate the effectiveness of n-butyl-2-cyanoacrylate surgical glue compared to the polyglactin 910 suture in repairing first- and second-degree perineal tears and episiotomy in vaginal births.

DESIGN

A parallel randomised controlled open trial.

SETTING

Birth centre in Itapecerica da Serra, São Paulo, Brazil.

PARTICIPANTS AND METHODS

The participants were 140 postpartum women allocated into four groups: two experimental groups repaired with surgical glue (n = 35 women with a first-degree tear; n = 35 women with a second-degree tear or episiotomy); two control groups sutured with thread (n = 35 women with a first-degree tear; n = 35 women with a second-degree tear or episiotomy). The outcomes were perineal pain and the healing process. Data collection was conducted in six stages: (1) up to 2 h after perineal repair; (2) from 12 to 24 h postpartum; (3) from 36 to 48 h; (4) from 10 to 20 days; (5) from 50 to 70 days; and (6) from 6 to 8 months. ANOVA, Student's t, Monte Carlo, x-square and Wald tests were used for the statistical analysis.

RESULTS

One hundred forty women participated in the first three stages, 110 in stage 4, 122 in stage 5, and 54 in stage 6. The women treated with surgical glue had less perineal pain (p ≤ 0.001). There was no difference in the healing process, but the CG obtained a better result in the coaptation item (p ≤ 0.001).

CONCLUSIONS

Perineal repair with surgical glue has low pain intensity and results in a healing process similar to suture threads.

Disempowering women-a mixed methods study exploring informational support about pain persisting after childbirth and its consequences

Background

Access to information is essential to achieving individual empowerment; meaning the ability to exercise control, manage one’s own condition and make informed decisions. However, studies have shown that information provided to women regarding physiological changes during the postpartum period and postpartum health was inadequate, incorrect, or inconsistent.

Methods

The aim of this study was to explore informational support about pain persisting after childbirth and its consequences. A sequential explanatory mixed methods design was used. In the first, quantitative phase, 1,171 women, who gave birth eight months earlier, completed a self-administered questionnaire. In the second, qualitative phase, 20 women who experienced chronic pain were interviewed. Descriptive statistics and qualitative content analysis were used to analyse the data.

Results

The majority of the women did not receive information about pain persisting after childbirth, or the information was insufficient or incorrect. They did not know when and where to seek help and did not consult health care professionals. In addition, the lack of information had a negative impact on women’s psychological well-being. All women expressed the need to be informed by health care professionals, irrespective of the individual risk of developing chronic pain.

Conclusions

Health services should ensure availability of information to give the women opportunity to achieve empowerment to make good health decisions, increase control over their health and well-being as well as to enhance their self-efficacy. We propose that a booklet or leaflet with relevant information about the risk of developing chronic pain, symptoms and treatment, along with advice about appropriate health care settings should be provided as part of antenatal or postnatal care.

Detailed classification of second-degree perineal tears in the delivery ward: an inter-rater agreement study

INTRODUCTION

Second-degree perineal tears can vary widely as to the extent of trauma, which may be relevant for women's pelvic floor health postpartum. However, the short- and long-term consequences of second-degree perineal tears are poorly understood, likely due to the lack of a detailed classification system. Such a classification system for second-degree tears has been suggested but the inter-rater agreement has not yet been assessed. The aim of this study was to assess the inter-rater agreement of the already established classification system for perineal tears recommended by the Royal College of Obstetricians and Gynaecologists (RCOG classification) among midwives. Further, we aimed to assess the inter-rater agreement of a classification system that provides three sub-categories for second-degree perineal tears.

MATERIAL AND METHODS

This was an inter-rater agreement study, conducted at Akershus University Hospital in Norway from 31 August to 29 November 2020. All midwives working in the delivery ward participated in the study. Midwives classified the integrity of the perineum of all women delivering vaginally within the study period. During the first month of the study, tears were classified by two midwives who were blinded to each other's findings, and the agreement of the RCOG classification was assessed. The following month, the detailed classification system was introduced to the midwifery staff. The last month, perineal tears were classified by two midwives using the detailed classification system, and the agreement was assessed. Inter-rater agreement was measured using Fleiss multirater kappa (k) and Kendall's coefficient of concordance (KCC_w ).

RESULTS

The inter-rater agreement for the RCOG classification was good to very good, with k = 0.705 (95% confidence interval [CI] 0.62-0.79, P < 0.001), KCC_w  = 0.928 (P < 0.001). The inter-rater agreement for the detailed classification system was good to very good, with k = 0.748 (95% CI 0.67-0.83, P < 0.001), KCC_w  = 0.956 (P < 0.001).

CONCLUSIONS

The inter-rater agreement among midwives using both the RCOG classification and the detailed classification system among midwives was good to very good. The detailed classification system provides additional information about the extent of tissue trauma in second-degree tears, warranted for future research on women's pelvic floor health postpartum.

Influence of a Virtual Exercise Program throughout Pregnancy during the COVID-19 Pandemic on Perineal Tears and Episiotomy Rates: A Randomized Clinical Trial

The complications associated with COVID-19 confinement (impossibility of grouping, reduced mobility, distance between people, etc.) influence the lifestyle of pregnant women with important associated complications regarding pregnancy outcomes. Therefore, perineal traumas are the most common obstetric complications during childbirth. The aim of the present study was to examine the influence of a supervised virtual exercise program throughout pregnancy on perineal injury and episiotomy rates during childbirth. A randomized clinical trial design (NCT04563065) was used. Data were collected from 98 pregnant women without obstetric contraindications who attended their prenatal medical consultations. Women were randomly assigned to the intervention (IG, N = 48) or the control group (CG, N = 50). A virtual and supervised exercise program was conducted from 8-10 to 38-39 weeks of pregnancy. Significant differences were found between the study groups in the percentage of episiotomies, showing a lower episiotomy rate in the IG (N = 9/12%) compared to the CG (N = 18/38%) (χ² (3) = 4.665; p = 0.031) and tears (IG, N = 25/52% vs. CG, N = 36/73%) (χ² (3) = 4.559; p = 0.033). A virtual program of supervised exercise throughout pregnancy during the current COVID-19 pandemic may help reduce rates of episiotomy and perineal tears during delivery in healthy pregnant women.

Effects of Breastfeeding on Endometriosis-Related Pain: A Prospective Observational Study

Endometriosis is a gynecological estrogen-dependent disease whose commonest pain symptoms are dysmenorrhea, dyspareunia, and acyclic chronic pelvic pain (CPP). Hormonal changes occurring during breastfeeding seem to reduce pain and disease recurrence. The aim of this observational prospective study was to assess the effect of breastfeeding on pain and endometriotic lesions in patients with endometriosis and to evaluate a possible correlation between the duration of breastfeeding, postpartum amenorrhea, and pain. Out of 156 pregnant women with endometriosis enrolled, 123 who breastfed were included in the study and were monitored for 2 years after delivery; 96/123 exclusively breastfed for at least 1 month. Mode of delivery, type and duration of breastfeeding, intensity of pain symptoms, and lesion size before pregnancy and during the 24-month follow-up were analyzed. All patients experienced a significant reduction in dysmenorrhea proportional to the duration of breastfeeding. CPP was significantly reduced only in women who exclusively breastfed. No significant improvement in dyspareunia was observed. Ovarian endometriomas were significantly reduced. Therefore, breastfeeding, particularly if exclusive, may cause improvement in dysmenorrhea and CPP proportional to the duration of breastfeeding, as well as a reduction in the size of ovarian endometriomas.

[Efficacy of collagen infiltrations in the pelvic pain caused by episiotomy and caesarean scars. Pilot randomized clinical trial]

BACKGROUND AND AIMS

Pelvic pain is a frequently consulted symptom in pelvic floor rehabilitation units. The aim of this study was to evaluate the efficacy of collagen infiltrations in pain and the appearance of scars from perineal tears, episiotomies and caesarean sections.

MATERIAL AND METHODS

Pilot randomized, controlled and single-blind clinical trial. Control group (CG) patients received conventional rehabilitation treatment. Additionally, those in the intervention group (IG) received 3-5 collagen infiltrations. The patients were evaluated at baseline and 6 weeks post-intervention. The main outcome was pain and it was evaluated with the visual analog scale and McGill Pain Questionnaire. As secondary outcomes, the appearance of the scar was evaluated by Vancouver Scar Scale and the Patient Scar Assessment Scale. A sample of 15 women was analyzed, 8 in the CG and 7 in the IG.

RESULTS

The mean age was 33.1 years (SD 4.1). The intragroup analysis showed a significant decrease of the visual analog scale punctuation and total McGill Pain Questionnaire score and the PRI-Emotional dimension of the McGill Pain Questionnaire. In the IG, a significant decrease was also observed in the PRI-Sensorial and PRI-Evaluative dimensions in comparison with baseline situation. In both groups, a significant improvement in the appearance of the scar was observed. In the intergroup analysis, a greater decrease in pain was observed in PRI-Sensorial subscale of the McGill Pain Questionnairein the IG (-15.1 vs. -6; P=.040).

CONCLUSIONS

Collagen infiltrations may improve pain and the appearance of painful scars.

Musculoskeletal lower back load of accoucheurs during childbirth - A pilot and feasibility study

INTRODUCTION

Back problems represent one of the leading causes of accouchers' work-related musculoskeletal morbidities. The correct execution of birth-related maneuvers including manual perineal protection is crucial not only for the mother and child but also for obstetricians and midwives to reduce any strain on their musculoskeletal system. Therefore, the overall aim of this study was to test the feasibility of determining the effect of different accouchers' postures (standing and kneeling) on their musculoskeletal system.

METHODS

The biomechanical analysis is based on musculoskeletal simulations that included motion recordings of real deliveries as well as deliveries conducted on a birthing simulator. These simulations were then used to determine individual joints' loads.

RESULTS

In the kneeling posture, both a low intra-operator variability and a lower average maximum load of the lower back was observed. For the standing position the spine load was reduced by pivoting the elbow on the accouchers' thigh, which in turn was associated with a significantly greater load on the shoulder joint.

CONCLUSION

The study demonstrated the feasibility of our technique to assess joints loads. It also provided initial data indicating that a posture that reduces spinal flexion and tilt, achieved in this study by the kneeling, can significantly reduce the strain on the practitioner's musculoskeletal system.

Grieving over the past and struggling forward - a qualitative study of women's experiences of chronic pain one year after childbirth

OBJECTIVE

To describe women's experiences of chronic pain related to childbirth approximately one year after labour.

DESIGN

A qualitative design with face-to-face interviews analysed using inductive qualitative content analysis.

PARTICIPANTS

Twenty women who reported chronic pain, with onset during pregnancy and/or following labour, approximately one year after childbirth.

FINDINGS

The analysis revealed an essential theme, "Grieving over the past and struggling forward", and three categories "Mourning the losses", "Struggling with the present" and "Managing the future".

CONCLUSIONS

This study provides new knowledge about women's experiences of chronic pain one year after childbirth. The pain severely reduced women´s previous ability to perform physical and social activities, negatively impacted psychological well-being and altered their self-image. Most of the women adopted a positive attitude and hoped for improved health in the future, although constantly struggling with the pain and its consequences.

IMPLICATIONS FOR PRACTICE

This knowledge is particularly important as chronic pain may not diminish with time in predisposed individuals who may need help and support from health professionals in their endeavour to manage their pain. Healthcare providers, i.e. midwives, gynaecologists and general practitioners need to understand women´s experiences of chronic pain from their own perspective to improve identification and treatment of pain following childbirth, thus preventing women's suffering and potential long-term health problems. Future studies are warranted to further explore and discuss women's coping strategies, health seeking behaviour and experiences of health care.

Prevalence, characteristics, and impact of pain during the postpartum period

OBJECTIVE

To identify the prevalence of pain in puerperal women, describe the characteristics of pain and its impacts on the performance of daily life activities, and evaluate satisfaction with received analgesia.

METHOD

Cross-sectional study which included women who had given birth. These were evaluated within 72 hours postpartum in a public teaching hospital in São Paulo city. Obstetric and clinical data were evaluated, as well as presence and characteristics of pain and its impact on daily activities.

RESULTS

A total 128 women participated in this study. The prevalence of pain was 36.7% during the interview and 54.6% in the previous 24 hours. The main pain site was the abdominal region (64.7%) and pain intensity was moderate to 48.9% of women, with intermittent frequency in 58% of the cases. There was a significant association between presence of pain and type of delivery (cesarean; p=0.030). Not being able to provide care to the newborn, requiring going to a different unit, increased pain perception (p=0.038). A significant impact of pain on the capacity of walking, eating, sleeping, taking care of the baby, evacuating, breathing deeply, breastfeeding, and sitting was verified.

CONCLUSION

Pain was frequent during the postpartum period and significantly affected the mothers' activities, indicating a need for improving pain management in puerperium.

Raising awareness about chronic pain and dyspareunia among women - a Swedish survey 8 months after childbirth

Background and aims Although several studies have been conducted, knowledge about chronic pain and dyspareunia after childbirth is still limited. The aim of this study was to explore the prevalence of chronic pain 8 months after childbirth in a cohort of Swedish women. The characteristics of chronic pain, such as, pain intensity, localization and frequency as well as pain interference with daily activities were examined. An additional aim was to describe the prevalence and intensity of dyspareunia. Methods Data were obtained through two self-administered questionnaires and the patient record system, Obstetrix. The first questionnaire was distributed on the maternity ward, 24-36 h after labour, to Swedish-speaking women who had given birth to a living child (n = 1,507). The second questionnaire was sent by post 8 months after childbirth. We collected data about demographic and social characteristics, pain presence and its onset, as well as pain intensity, frequency, bodily localization and pain interference with activities of women's daily life. Results In total, 1,171 (77.7%) responded to both questionnaires and were included in the analysis. Eight months after giving birth, totally 16.7% (195/1,171) of the women reported chronic pain related to childbirth. Of these, 9.1% (106/1,171) of women reported chronic pain with onset during pregnancy, 4.5% (53/1,171) experienced chronic pain with onset following labour and 3.1% (36/1,171) of women had both chronic pain with onset during pregnancy and chronic pain with onset following labour (each participant could only appear in one of the groups). Women reported a lower prevalence of chronic pain after vaginal delivery than caesarean section (61/916, 6.7% vs. 28/255, 11%, p = 0.021, OR 1.73, 95% CI 1.1-2.8). Moreover, 19.2% (211/1,098) of women experienced dyspareunia. There was no difference regarding prevalence of dyspareunia and the mode of delivery. Of those women who had a vaginal delivery, 19.5% (167/858) experienced pain during intercourse and the corresponding number for women after caesarean section was 18.3% (44/240) (p = 0.694, OR 0.929, CI 0.6-1.3). Approximately 80% of women with chronic pain, and 60% of women that experienced dyspareunia, rated their worst pain as moderate or severe (NRS 4-10). The corresponding number regarding average chronic pain was between 50 and 70%. More than 35% of the women with chronic pain scored pain interference with daily activities as ≥4 on a 0-10 NRS. Conclusions In our study, chronic pain 8 months after childbirth was reported by one in six women and one in five of the women experienced dyspareunia. The intensity of both chronic pain and dyspareunia was reported as moderate to severe in a significant proportion of women and chronic pain interfered considerably with daily activities. Implications There is a need to raise awareness among healthcare providers of this clinical problem as well as to revise and upgrade education regarding pain after childbirth to prevent potential long-term health problems, women's suffering and increased need for health care. The development of strategies for prevention, follow-up and treatment of pain is warranted. More research, including women's experiences of pain as well as intervention studies, are also needed.
