Perineal massage for prevention of perineal trauma in childbirth

Effect of Prenatal Perineal Massage on Postpartum Perineal Injury and Postpartum Complications: A Meta-Analysis

Background

The efficacy of perineal massage is controversial. The study was aimed at comparing the effects of perineal massage on perineal injury and complications.

Methods

PubMed, Embase, the Cochrane Library, and ISI Web of Science were searched for literature on the relationship between prenatal perineal massage and postpartum perineal injury and complications until April 2022. Indicators included postpartum perineal tears, perineotomy, postpartum perineal pain, natural labour, and postpartum incontinence. Finally, RevMan5.4 software was used to analyze the extracted data.

Results

A total of 6487 subjects in 16 studies were included, with 3211 who received perineal massage and 3276 did not. There was no significant difference in 1-2 degree perineal tearing between the intervention group and the control group (RR = 0.96, 95% CI [0.90, 1.03], P = 0.30), and there was no heterogeneity between studies (P = 0.62, I² = 0%), indicating publication bias. Compared with the control group, prenatal perineal massage significantly reduced the incidence of 3-4 degree perineal tears (RR = 0.56, 95% CI [0.47, 0.67], P < 0.00001), and there was no heterogeneity between studies (P = 0.16, I² = 30%), indicating publication bias. Compared with the control group, prenatal perineal massage reduced the risk of lateral perineal resection (RR = 0.87, 95% CI [0.80, 0.95], P = 0.001), and there was no heterogeneity between studies (P = 0.14, I² = 31%), and there was no publication bias. Compared with the control group, prenatal perineal massage reduced the risk of postpartum pain at 3 months (RR = 0.64, 95% CI [0.51, 0.81], P = 0.0002). There was no significant heterogeneity among studies (P = 0.23, I² = 31%).

Conclusion

Compared with no prenatal perineal massage, prenatal perineal massage can reduce the risk of perineal injury, the incidence of lateral perineal resection, and the incidence of long-term pain.

The effect of antenatal pelvic floor muscle exercises on labour and birth outcomes: a systematic review and meta-analysis

INTRODUCTION AND HYPOTHESIS

The current data on the effectiveness of antenatal pelvic floor muscle exercises (PFME) on childbirth outcomes are limited. Therefore, in this study the effect of antenatal PFMEs on labour and birth outcomes was assessed by undertaking a meta-analysis.

METHODS

Databases were systematically searched from 1988 until June 2019. Randomised controlled trials (RCTs) and quasi-experimental studies were included. The methodological quality of studies was assessed using Cochrane Collaboration tools. The outcomes of interest were: duration of first and second stage of labour, episiotomy and perineal outcomes, mode of birth (spontaneous vaginal birth, instrumental birth and caesarean section) and fetal presentation. The mean difference (MD) and risk ratio RR) with the corresponding 95% confidence intervals (CIs) were calculated to assess the association between PFME and the childbirth outcomes.

RESULTS

A total of 16 articles were included (n = 2,829 women). PFME shortened the duration of the second stage of labour (MD: -20.90, 95%, CI: -31.82 to -9.97, I²: 0%, p = 0.0002) and for primigravid women (MD: -21.02, 95% CI: -32.10 to -9.94, I²: 0%, p = 0.0002). PFME also reduced severe perineal lacerations (RR 0.57, 95% CI: 0.38 to 0.84, I²: 30%, p = 0.005). No significant difference was seen in normal vaginal birth, caesarean section, instrumental birth and episiotomy rate. Most of the studies carried a moderate to high risk of bias.

CONCLUSION

Antenatal PFME may be effective at shortening the second stage of labour and reducing severe perineal trauma. These findings need to be interpreted considering the included studies' risk of bias. More high-quality RCTs are needed.

Perineal massage and training reduce perineal trauma in pregnant women older than 35 years: a randomized controlled trial

INTRODUCTION AND HYPOTHESIS

The aim of this study was to evaluate the effectiveness of perineal massage, pelvic floor muscle training (PFMT) and a pelvic floor dysfunction (PFD) prevention educational program in pregnant women above the age of 35 years to prevent perineal tear and episiotomy.

METHODS

A randomized parallel assignment study involved two groups of pregnant women at the obstetrics outpatient clinic 4 weeks prior to their due date. The first group (n = 200) was educated to do digital perineal massage and pelvic floor muscle training and received an educational PFD prevention program. The second group (n = 200) received only the prevention education program. Occurrence of perineal laceration was reported at time of delivery as a primary outcome. Statistical analysis was done using the IBM SPSS computer program (Statistical Package for the Social Sciences; IBM Corp, Armonk, NY, USA), release 22 for Microsoft Windows.

RESULTS

Delivery was significantly less complicated by perineal tear, episiotomy and postnatal pain in the first than in the second group (p < 0.05). Grades of perineal tear were mostly of first and second degree in the first group compared with the second group. We found a significantly lower need for analgesia and fewer ampoules required during the hospital stay in the first group (p < 0.001, 0.002, respectively).

CONCLUSIONS

Performing antenatal digital perineal massage and PFMT in addition to health education is recommended to reduce perineal complications.

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.

The Effect of Warm Compress Bistage Intervention on the Rate of Episiotomy, Perineal Trauma, and Postpartum Pain Intensity in Primiparous Women with Delayed Valsalva Maneuver Referring to the Selected Hospitals of Shiraz University of Medical Sciences in 2012-2013

BACKGROUND

Genital trauma during vaginal delivery may result from episiotomy, spontaneous perineal tears (perineum, vagina), or both. In 2012, this study aimed to investigate the effect of warm compress bistage intervention on the rate of episiotomy, perineal trauma, and postpartum pain intensity in the primiparous woman with delayed Valsalva maneuver.

METHODS

In this randomized clinical trial, which was performed in hospitals in Shiraz, Iran, in 2012-2013, 150 women were randomly divided into 2 groups: 1 intervention and 1 control. The intervention group received warm compress bistage intervention at 7-cm and 10-cm dilatation and zero position during the first and second stages of labor for 15 to 20 minutes, whereas the control group received the hospitals' routine care. After delivery, the prevalence of episiotomy; intact perineum; location, degree, and length of rupture; and postpartum pain intensity were assessed in the 2 groups. Following that, the data were analyzed with SPSS statistical software (version 16) using χ test, t test, and odds ratio.

RESULTS

The results revealed a significant difference between the intervention and control groups regarding the frequency of intact perinea (27% vs 6.7%) and the frequency of episiotomy (45% vs 90.70%). In addition, the frequency of the location of rupture (P = .019), mean length of episiotomy incision (P = .02), and mean intensity of pain the day after delivery (P < .001) were significantly lower in the intervention group compared with the control group. However, the rate of ruptures was higher in the intervention group.

CONCLUSIONS

Warm compress bistage intervention was effective in reducing episiotomies and the mean length of episiotomy incision, reducing pain after delivery, and increasing the rate of intact perinea. However, the rate of ruptures slightly increased in the intervention group compared with the control group.

The impact of obstetric gel on the second stage of labor and perineal integrity: a randomized controlled trial

OBJECTIVE

Dianatal® is a bioadhesive gliding film which reduces the opposing force to vaginal childbirth. We aimed to investigate the safety, applicability, and impact of Dianatal® obstetric gel on second stage of labor and perineal integrity.

METHODS

Low-risk singleton pregnancies at term were prospectively enrolled. Eligible women were randomly assigned to either labor management without using obstetric gel, or labor management using intermittent application of obstetric gel into the birth canal during vaginal examinations, starting at active phase of labor (≥4 cm dilation). The primary measured outcome was the length of second stage of labor.

RESULTS

Overall, 200 cases were analyzed. Demographic, obstetrical, and labor characteristics were similar between the groups. Neither adverse events nor maternal or neonatal side effects were observed. The mean lengths of the active and second stages of labor were comparable between the obstetric gel-treated and the control groups (157 versus 219 min and 48 versus 56 min, respectively). None of the women had grade III/IV perineal tears. Maternal and neonatal outcomes were not negatively influenced by using obstetric gel. No difference was found after sub-group analysis for spontaneous vaginal delivery.

CONCLUSION

Dianatal® obstetric gel is safe in terms of maternal or neonatal use. Albeit a trend toward shorter labor stages using Dianatal® obstetric gel, no significant differences were noted among the groups. In order to further investigate the influence of the obstetric gel on labor stage interval, perineal integrity and maternal and neonatal outcomes, larger randomized clinical trials are needed to be carried out.

Effect of perineal massage on the rate of episiotomy and perineal tearing

OBJECTIVE

To examine the effects of perineal massage during active labor on the frequency of episiotomy and perineal tearing.

METHODS

A randomized controlled study was conducted at a center in Sivas, Turkey, between January 1, 2010, and May 31, 2011. Healthy pregnant women presenting for their first or second delivery at 37-42 weeks of pregnancy were enrolled during the first stage of labor. Participants were randomly assigned (1:1) to the massage group (10-minute perineal massage with glycerol four times during the first stage and once during the second stage of labor) or control group (routine care). The frequency of episiotomy and perineal tearing were compared between the groups. Participants and investigators were not masked to group assignment.

RESULTS

Both groups contained 142 participants. Episiotomy was performed among 44 (31.0%) women in the massage group and 99 (69.7%) in the control group (P = 0.001). Lacerations were recorded among 13 (4.2%) women in the massage group and 6 (4.2%) in the control group (P = 0.096).

CONCLUSION

Application of perineal massage during active labor decreased the frequency of episiotomy procedures. ClinicalTrials.gov:NCT02201615.

Antibiotic prophylaxis for third- and fourth-degree perineal tear during vaginal birth

BACKGROUND

One to eight per cent of women suffer third-degree perineal tear (anal sphincter injury) and fourth-degree perineal tear (rectal mucosa injury) during vaginal birth, and these tears are more common after forceps delivery (28%) and midline episiotomies. Third- and fourth-degree tears can become contaminated with bacteria from the rectum and this significantly increases in the chance of perineal wound infection. Prophylactic antibiotics might have a role in preventing this infection.

OBJECTIVES

To assess the effectiveness of antibiotic prophylaxis for reducing maternal morbidity and side effects in third- and fourth-degree perineal tear during vaginal birth.

SEARCH METHODS

We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (31 August 2014) and the reference lists of retrieved articles.

SELECTION CRITERIA

Randomised controlled trials comparing outcomes of prophylactic antibiotics versus placebo or no antibiotics in third- and fourth-degree perineal tear during vaginal birth.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed the trial reports for inclusion and risk of bias, extracted data and checked them for accuracy.

MAIN RESULTS

We identified and included one trial (147 women from a pre-planned sample size of 310 women) that compared the effect of prophylactic antibiotic (single-dose, second-generation cephalosporin - cefotetan or cefoxitin, 1 g intravenously) on postpartum perineal wound complications in third- or fourth-degree perineal tears compared with placebo. Perineal wound complications (wound disruption and purulent discharge) at the two-week postpartum check up were 8.20% and 24.10% in the treatment and the control groups respectively (risk ratio (RR) 0.34, 95% confidence interval (CI) 0.12 to 0.96). However, the high failed-appointment rate may limit the generalisability of the results. The overall risk of bias was low except for incomplete outcome data. The quality of the evidence using GRADE was moderate for infection rate at two weeks' postpartum, and low for infection rate at six weeks' postpartum.

AUTHORS' CONCLUSIONS

Although the data suggest that prophylactic antibiotics help to prevent perineal wound complications following third- or fourth-degree perineal tear, loss to follow-up was very high. The results should be interpreted with caution as they are based on one small trial.

Can we find the perfect oil to protect the perineum? A randomized-controlled double-blind trial

OBJECTIVE

To determine whether perineal massage during the second stage of labor using oil enriched with vitamins, increases the chances of delivering with an intact perineum as compared to perineal massage using pure liquid wax.

METHOD

A prospective, randomized, double-blind study was conducted. Women were assigned to liquid wax (jojoba oil) versus purified formula of almond and olive oil, enriched with vitamin B1, B2, B6, E and fatty acids. The caregivers used the oils during the second stage of labor.

RESULTS

A total of 164 women undergoing vaginal delivery were recruited. No significant differences regarding perineal lacerations, number of sutures and length of suturing were noted between the two groups. Likewise, while analyzing separately nulliparous and multiparous women, no significant differences were noted. Controlling for birth weight >4000 g, using the Mantel-Haenszel technique, no association was noted between perineal lacerations and the type of oil used (weighted OR = 0.9, 95% CI 0.3-2.4; p = 0.818).

CONCLUSION

The type of the oil used during the second stage of labor for prevention of perineal tears has no effect on the integrity of the perineum. Accordingly, it seems that there is no perfect oil.

Mensuração e caracterização da dor após episiotomia e sua relação com a limitação de atividades

Trata-se de um estudo descritivo realizado com cinquenta mulheres em pós-parto vaginal com episiotomia. Objetivou-se mensurar e caracterizar a dor perineal em primíparas submetidas ao parto normal com episiotomia e verificar as atividades limitadas pela dor. Para avaliação da dor foi utilizada a Escala Numérica e o Questionário McGill, bem como um formulário para analisar as atividades que estavam limitadas. A média de dor perineal encontrada foi cinco. As categorias sensorial e avaliação subjetiva foram as mais selecionadas no Questionário McGill. A dor perineal foi caracterizada como latejante, que repuxa, que esquenta, ardida, dolorida, chata, incômoda, que prende e que deixa tensa. Sentar, deitar e deambular foram as atividades mais limitadas. Em conclusão, foi possível verificar a presença de dor perineal nas puérperas causada pela episiotomia e identificar que as atividades de sentar, deitar e deambular estavam limitadas por este sintoma.

Reducing perineal trauma through perineal massage with vaseline in second stage of labor

PURPOSE

Maintaining an intact perineum is a highly regarded aim in delivery procedures today. Since perineal massage is a common practice during delivery, the present study aims to investigate the effect of perineal massage with Vaseline on perineal trauma (rate of episiotomy procedures and perineal tears).

METHOD

Ninety primiparous women (aged between 18 and 30 years with gestational age of 38-42 weeks) were selected sequentially in Tehran in 2009. Once participants' characteristics were registered, they were randomly assigned to the intervention (perineal massage with Vaseline) or control groups. In the massage group, perineal massage was performed in the second stage of delivery once the genitalia were treated with sterilized Vaseline. The perineum was examined after the delivery in terms of episiotomy or tear and its severity degree.

RESULTS

The two groups were homogeneous in terms of demographic data, weight gain during pregnancy, gestational age, abortion history and fetal weight. The second stage of delivery was significantly shorter in the massage group than the control group and the massage group had significantly more intact perineum (P = 0.004). In addition, lower episiotomy and higher first- and second-degree perineal tears were seen in the massage group in comparison with the control one (P < 0.001). Neither of the groups suffered from third- and fourth-degree tears.

CONCLUSION

The findings showed that the perineal massage with Vaseline in the second stage of labor increases perineal integrity and decreases perineal traumas (episiotomy and tears). So, it seems that the perineal massage could be an effective way to preserve an intact perineum in labor.

Associação entre a analgesia epidural e o trauma perineal no parto vaginal

O objetivo deste estudo foi analisar a associação entre a analgesia epidural e a laceração perineal em mulheres submetidas ao parto vaginal. Foi realizado um estudo descritivo e transversal, para o qual foram pesquisados 109 prontuários de mulheres assistidas durante o processo de parturição, em uma maternidade em Ribeirão Preto. Os dados foram coletados nos meses de março e abril de 2003. Para analisar a correlação entre as variáveis foi aplicado o teste qui-quadrado. Foi realizado parto normal em 91,7% (100) das parturientes e fórceps em 8,2% (9). Na análise dos dados, 74,3% da amostra receberam analgesia epidural; destas, 26,5% tiveram algum grau de laceração perineal e 9,1%, períneo íntegro, não sendo possível verificar a associação entre as variáveis mencionadas. Não foi verificada, neste estudo, significância estatística para afirmar que as condições do períneo após o parto vaginal e a utilização da analgesia epidural estão associadas (valor x²4GL= 3,1).

Obstetric gel shortens second stage of labor and prevents perineal trauma in nulliparous women: a randomized controlled trial on labor facilitation

OBJECTIVE

To determine whether the obstetric gel shortens the second stage of labor and exerts a protective effect on the perineum.

METHOD

A total of 251 nulliparous women with singleton low-risk pregnancies in vertex position at term were recruited. A total of 228 eligible women were randomly assigned to Group A, without obstetric gel use, or to Group B, obstetric gel use, i.e., intermittent application into the birth canal during vaginal examinations, starting at the early first stage of labor (prior to 4 cm dilation) and ending with delivery.

RESULTS

A total of 183 cases were analyzed. For vaginal deliveries without interventions, such as C-section, vaginal operative procedure or Kristeller maneuver, obstetric gel use significantly shortened the second stage of labor by 26 min (30%) (P=0.026), and significantly reduced perineal tears (P=0.024). First stage of labor and total labor duration were also shortened, but not significantly. Results did not show a significant change in secondary outcome parameters, such as intervention rates or maternal and newborn outcomes. No side effects were observed with obstetric gel use.

CONCLUSION

Systematic vaginal application of obstetric gel showed a significant reduction in the second stage of labor and a significant increase in perineal integrity. Future studies should further investigate the effect on intervention rates and maternal and neonatal outcome parameters.

Perineal outcomes and maternal comfort related to the application of perineal warm packs in the second stage of labor: a randomized controlled trial

BACKGROUND

Perineal warm packs are widely used during childbirth in the belief that they reduce perineal trauma and increase comfort during late second stage of labor. The aim of this study was to determine the effects of applying warm packs to the perineum on perineal trauma and maternal comfort during the late second stage of labor.

METHODS

A randomized controlled trial was undertaken. In the late second stage of labor, nulliparous women (n = 717) giving birth were randomly allocated to have warm packs (n = 360) applied to their perineum or to receive standard care (n = 357). Standard care was defined as any second-stage practice carried out by midwives that did not include the application of warm packs to the perineum. Analysis was on an intention-to-treat basis, and the primary outcome measures were requirement for perineal suturing and maternal comfort.

RESULTS

The difference in the number of women who required suturing after birth was not significant. Women in the warm pack group had significantly fewer third- and fourth-degree tears and they had significantly lower perineal pain scores when giving birth and on "day 1" and "day 2" after the birth compared with the standard care group. At 3 months, they were significantly less likely to have urinary incontinence compared with women in the standard care group.

CONCLUSIONS

The application of perineal warm packs in late second stage does not reduce the likelihood of nulliparous women requiring perineal suturing but significantly reduces third- and fourth-degree lacerations, pain during the birth and on days 1 and 2, and urinary incontinence. This simple, inexpensive practice should be incorporated into second stage labor care.

Antibiotic prophylaxis for fourth-degree perineal tear during vaginal birth

BACKGROUND

One to eight per cent of women suffer third-degree perineal tears (anal sphincter injury) and fourth-degree perineal tear (rectal mucosa injury) during vaginal birth, and these tears are more common after forceps delivery (28%) and midline episiotomies. Fourth-degree tears can become contaminated with bacteria from the rectum and this significantly increases in the chance of perineal wound infection. Prophylactic antibiotics might have a role in preventing this infection.

OBJECTIVES

To assess the effectiveness of antibiotic prophylaxis for reducing maternal morbidity and side-effects in fourth-degree perineal tear during vaginal birth.

SEARCH STRATEGY

We searched the Cochrane Pregnancy and Childbirth Group Trials Register (30 July 2005), the Cochrane Central Register of Controlled Trials (The Cochrane Library, Issue 2, 2005), MEDLINE (1966 to 15 July 2005), and LILACS (1982 to 15 July 2005).

SELECTION CRITERIA

Randomised controlled trials which reported data comparing outcomes of prophylactic antibiotics versus placebo or no antibiotics in fourth-degree perineal tear during vaginal birth.

DATA COLLECTION AND ANALYSIS

No trials were found that met the selection criteria.

MAIN RESULTS

No randomised controlled trials were identified.

AUTHORS' CONCLUSIONS

There are insufficient data to support a policy of routine prophylactic antibiotics in fourth-degree perineal tear during vaginal birth. A well-designed randomised controlled trial is needed.

Is it possible to predict or prevent third degree tears?

OBJECTIVES

This paper reviews the causes anal sphincter injury during vaginal delivery. It emphasises that they are not usually the result of poor obstetric care. The role of the colorectal surgeon in their management is discussed.

METHODS

Medline was searched using the key words third degree tears, pregnancy, risk factors, prevention and recurrence risk. A hand search of journals and located articles was made. Two hundred and twenty three papers were identified, 84 are referenced.

RESULTS

The reported incidence of anal sphincter tears is usually between 0.5% and 2.5% of vaginal deliveries. Maternal factors such as parity and age and obstetric factors such as mode of presentation, the use of forceps and the size of the baby all influence the incidence of sphincter tears. Predicting tears in individual women is inaccurate and midwifery practices can do little to prevent them. Reducing pelvic floor morbidity by increasing the caesarean section rate would require that a large number of caesarean sections be done to prevent a small number of tears. The recognition of perineal trauma is improved by training. Accurate apposition of the sphincters with antibiotic cover and post-operative laxatives are the important technical aspects of the repair. Colorectal follow up helps to identify those women with symptoms and allows advice about the advisability of subsequent vaginal deliveries. A previous third degree tears increases the risk of a subsequent one, although the overall risk remains low. A second vaginal delivery after a third degree tear that has resulted in a functional deficit predisposes to worsening function. When there is no residual anatomical defect and no functional loss, there is no evidence of increased risk of incontinence following another vaginal delivery.

CONCLUSION

Vaginal delivery will continue to be the main method of delivery and will continue to generate a low incidence of pelvic floor morbidity. The management of injury to the anal sphincter is facilitated by close co-operation between obstetricians and colorectal surgeons.

Perineal massage in labour and prevention of perineal trauma: randomised controlled trial

OBJECTIVE

To determine the effects of perineal massage in the second stage of labour on perineal outcomes.

DESIGN

Randomised controlled trial.

PARTICIPANTS

At 36 weeks' gestation, women expecting normal birth of a singleton were asked to join the study. Women became eligible to be randomised in labour if they progressed to full dilatation of the cervix or 8 cm or more if nulliparous or 5 cm or more if multiparous. 1340 were randomised into the trial.

INTERVENTION

Massage and stretching of the perineum during the second stage of labour with a water soluble lubricant.

MAIN OUTCOME MEASURES

PRIMARY OUTCOMES

rates of intact perineum, episiotomies, and first, second, third, and fourth degree tears.

SECONDARY OUTCOMES

pain at three and 10 days postpartum and pain, dyspareunia, resumption of sexual intercourse, and urinary and faecal incontinence and urgency three months postpartum.

RESULTS

Rates of intact perineums, first and second degree tears, and episiotomies were similar in the massage and the control groups. There were fewer third degree tears in the massage group (12 (1.7%) v 23 (3.6%); absolute risk 2.11, relative risk 0.45; 95% confidence interval 0.23 to 0.93, P<0.04), though the trial was underpowered to measure this rarer outcome. Groups did not differ in any of the secondary outcomes at the three assessment points.

CONCLUSIONS

The practice of perineal massage in labour does not increase the likelihood of an intact perineum or reduce the risk of pain, dyspareunia, or urinary and faecal problems.
