Perineal injuries during vaginal birth in low-resource countries.

Birth related perineal trauma (BRPT) and obstetric anal sphincter injuries (OASIS) are leading causes of anal incontinence in women, which negatively impacts on their quality of life, resulting in low self-esteem and abandonment. In low resource countries (LRC), the true incidence is not known and since most births are unattended or occur in community-based health care systems, one can anticipate that it is a significant problem. Dissemination of information to women, education of traditional birth attendants, improvement of resources and transport, and training of health professionals on the detection and appropriate surgical management of these injuries will reduce morbidity and improve outcome. Intrapartum measures such as controlled head descent and perineal support, correct episiotomy techniques and selective use of instruments to assist vaginal births is pivotal in avoiding these injuries. Policy makers should prioritize maternity care in LRC, and research is urgently needed to address all aspects of BRPT.

Assessing Alternative Approaches for Wound Closure in a National Pediatric Learning Health System.

INTRODUCTION: Our objective was to perform a feasibility study using real-world data from a learning health system (LHS) to describe current practice patterns of wound closure and explore differences in outcomes associated with the use of tissue adhesives and other methods of wound closure in the pediatric surgical population to inform a potentially large study. METHODS: A multi-institutional cross-sectional study was performed of a random sample of patients <18 y-old who underwent laparoscopic appendectomy, open or laparoscopic inguinal hernia repair, umbilical hernia repair, or repair of traumatic laceration from January 1, 2019, to December 31, 2019. Sociodemographic and operative characteristics were obtained from 6 PEDSnet (a national pediatric LHS) children's hospitals and OneFlorida Clinical Research Consortium (a PCORnet collaboration across 14 academic health systems). Additional clinical data elements were collected via chart review. RESULTS: Of the 692 patients included, 182 (26.3%) had appendectomies, 155 (22.4%) inguinal hernia repairs, 163 (23.6%) umbilical hernia repairs, and 192 (27.8%) traumatic lacerations. Of the 500 surgical incisions, sutures with tissue adhesives were the most frequently used (n = 211, 42.2%), followed by sutures with adhesive strips (n = 176, 35.2%), and sutures only (n = 72, 14.4%). Most traumatic lacerations were repaired with sutures only (n = 127, 64.5%). The overall wound-related complication rate was 3.0% and resumption of normal activities was recommended at a median of 14 d (interquartile ranges 14-14). CONCLUSIONS: The LHS represents an efficient tool to identify cohorts of pediatric surgical patients to perform comparative effectiveness research using real-world data to support medical and surgical products/devices in children.

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, I 2 = 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, I 2 = 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, I 2 = 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, I 2 = 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.

National level data analysis of facial lacerations in Korea using the National Health Insurance Service (NHIS) database.

ABSTRACT: No national epidemiological investigations have been conducted recently regarding facial lacerations. The study was performed using the data of 3,634,229 people during the 5-year period from 2014 to 2018 archived by the National Health Information Database (NHID) of the Health Insurance Review and Assessment Service. Preschool and children under 10 years old accounted for about one-third of patients. Facial lacerations were concentrated in the "T-shaped" area, which comprised forehead, nose, lips, and the perioral area. The male to female ratio for all study subjects was 2.16:1. Age and gender are significantly related with each other (P < .001). Mean hospital stays decreased, and numbers of outpatient department visits per patient were highest for hospitals and lowest for health agencies. Over the study period, hospital costs per patient in tertiary and general hospitals increased gradually. Preschool and school-aged children are vulnerable to trauma. Male patients outnumbered female patients by a factor of more than 2. The "T-shaped'" area around forehead is vulnerable to injury. Total cost of medical care benefits per patient in tertiary hospitals was about 7 times on average than in health agencies. Regarding functional, behavioral, and aesthetic outcomes, more attention should be paid to epidemiologic data and hospital costs for facial lacerations.

Epidemiology of injuries in Olympic-style karate competitions: systematic review and meta-analysis.

OBJECTIVE: To report the epidemiology of injuries in Olympic-style karate competitions. DESIGN: Systematic review and meta-analysis. Pooled estimates of injury incidence rates per 1000 athlete-exposures (IIRAE) and per 1000 min of exposure (IIRME) were obtained by fitting random-effects models. DATA SOURCES: MEDLINE, Embase, AMED, SPORTDiscus and AusportMed databases were searched from inception to 21 August 2019. ELIGIBILITY CRITERIA: Prospective cohort studies published in peer-reviewed journals and reporting injury data (ie, incidence, severity, location, type, mechanism or risk factors) among athletes participating in Olympic-style karate competition. RESULTS: Twenty-eight studies were included. The estimated IIRAE and IIRME were 88.3 (95%CI 66.6 to 117.2) and 39.2 (95%CI 30.6 to 50.2), respectively. The most commonly injured body region was the head and neck (median: 57.9%; range: 33.3% to 96.8%), while contusion (median: 68.3%; range: 54.9% to 95.1%) and laceration (median: 18.6%; range: 0.0% to 29.3%) were the most frequently reported types of injury. Despite inconsistency in classifying injury severity, included studies reported that most injuries were in the least severe category. There was no significant difference in IIRME between male and female karate athletes (rate ratio 1.09; 95%CI 0.88 to 1.36). CONCLUSION: Karate athletes sustain, on average, 1 injury every 11 exposures (bouts) or approximately 25 min of competition. The large majority of these injuries were minor or mild in severity.

The impact of a nationwide hands-on workshop on the diagnostic rates and management of obstetrical anal sphincter Injuries in Israel.

AIM: The aim was to evaluate the influence of a half day, hands-on, workshop on the detection and repair of obstetric anal sphincter injuries (OASIs). METHOD: Starting in February 2011, hands-on workshops for the diagnosis and repair of OASIs were delivered by trained urogynaecologists in departments of tertiary medical centres in Israel. The structure of the hands-on workshop resembles the workshop organized at the International Urogynecological Association annual conferences. Participants included medical staff, midwives and surgical residents from each medical centre. We collected data regarding the rate of OASIs, 1 year before and 1 year following the workshop, in 11 medical centres. The study population was composed of parturients with the following inclusion criteria: singleton pregnancy, vertex presentation and vaginal delivery. Pre-viable preterm gestations (< 24 weeks), birth weight < 500 g, stillborn, and those with major congenital anomalies, multifoetal pregnancies, breech presentations and caesarean deliveries were excluded from the analysis. RESULTS: In the reviewed centres, 70 663 (49.3%) women delivered prior to the workshop (pre-workshop group) and 72 616 (50.7%) women delivered following the workshop (post-workshop group). Third- or fourth-degree perineal tears occurred in 248 women (0.35%) before the workshop, and in 328 (0.45%) following the workshop, a significant increase of 28.7% (P = 0.002). The increase in diagnosis was significant also in women with third-degree tears alone, 226 women (0.32%) before the workshop and 298 (0.41%) following the workshop, an increase of 28.3% (P = 0.005). CONCLUSION: The detection rate of OASIs has significantly increased following the hands-on workshop. The implementation of such programmes is crucial for increasing awareness and detection rates of OASI following vaginal deliveries.

Maternal and neonatal outcome of births planned in alongside midwifery units: a cohort study from a tertiary center in Germany.

BACKGROUND: For healthy women entering birth after uneventful pregnancy, midwife-led models of care have the potential to reduce interventions and increase the vaginal birth rate. In Germany, 98.4% of women are giving birth in consultant-led obstetric units. Alongside midwifery units (AMU) have been established in 2003. We compared the outcome of women registered for planned birth in the AMU at our hospital with a matched group of low-risk women who gave birth in standard obstetric care during the same period of time. METHODS: We used a retrospective cohort study design. The study group consisted of all women admitted to labor ward who had registered for birth in AMU from 2010 to 2017. For the control group, low-risk women were selected; additionally, matching was performed for parity. Mode of birth was chosen as primary outcome parameter for the mother. For the neonate, a composite primary outcome (5-min Apgar < 7 or umbilical cord arterial pH < 7.10 or transfer to specialist neonatal care) was defined. Secondary outcomes included epidural anesthesia, duration of the second stage of labor, episiotomy, obstetric injury, and postpartum hemorrhage. Non-inferiority was assessed, and multiple logistic regression analysis was performed. RESULTS: Six hundred twelve women were admitted for labor in AMU, the control group consisted of 612 women giving birth in standard obstetric care. Women in the study group were on average older and had a higher body mass index (BMI); birthweight was on average 95 g higher. Non-inferiority could be established for the primary outcome parameters. Epidural anesthesia and episiotomy rates were lower, and the mean duration of the second stage of labor was shorter in the study group; second-degree perineal tears were less common, higher-order obstetric lacerations occurred more frequently. Overall, 50.3% of women were transferred to standard obstetric care. Regression analysis revealed effects of parity, age and birthweight on the chance of transfer. CONCLUSION: Compared to births in our consultant-led obstetric unit, the outcome of births planned in the AMU was not inferior, and intervention rates were lower. Our results support the integration of AMU as a complementary model of care for low-risk women.

Impact of a selective use of episiotomy combined with Couder's maneuver for the perineal protection.

PURPOSE: To evaluate the impact of a selective use of episiotomy combined with Couder's maneuver on the incidence of perineal tears in spontaneous term deliveries. METHODS: A comparative, retrospective, mono-centric study in a university maternity unit was designed and included all primiparous women who delivered spontaneously after 37 weeks of gestation in cephalic presentation. Two cohorts were studied, before and after the practice of Couder's maneuver. In the first cohort, the ''OSE cohort'' only selective episiotomies were performed from January 2009 to December 2010. In the second cohort, from January 2016 to December 2017, the ''SEC cohort'' selective episiotomies combined with Couder's maneuver were performed by midwives and obstetricians. The primary outcome was the type of perineal tears, according to the Royal College of Obstetricians and Gynaecologists (RCOG) classification. RESULTS: A total of 2081 patients were included: 909 patients in the OSE cohort and 1172 patients in the SEC cohort. Couder's maneuver was performed in 59% of the SEC cohort. In the SEC cohort, there were an increase in the number of intact perinea (55% versus 63%, p < 0.001), a decrease in second-degree perineal tears (18% versus 11%, p < 0.001) and a decrease in labia minora tears (48% versus 37%, p < 0.001). The rate of obstetrical anal sphincter injuries was less than 1% in both cohorts (0.3% versus 0.5%, p = 0.7). CONCLUSION: A selective use of episiotomy combined with Couder's maneuver could reduce the incidence of perineal tears, particularly second-degree perineal tears, without increasing the rate of obstetrical anal sphincter injuries.

Water Birth Maternal and Neonatal Outcomes Among Midwifery Clients in Alberta, Canada, from 2014 to 2017: A Retrospective Study.

OBJECTIVES: This study sought to evaluate retrospectively the maternal and neonatal outcomes of water births (WBs) managed by Registered Midwives in Alberta compared with traditional or "land" vaginal birth outcomes for clinical evidence or knowledge and to assist in health care management planning. METHODS: This study was a retrospective cohort comparison of maternal and neonatal outcomes of WB (1716) and traditional or land birth (non-WB) (21 320) from selected low-risk maternal cohorts with spontaneous onset of labour and vaginal delivery in Alberta (2014-2017) using Alberta Perinatal Health Program data sets. Anonymized client and patient records linked the Alberta Perinatal Health Program data with inpatient Discharge Abstract Database for newborn and/or maternal personal health number (PHN/ULI) analyzed using SPSS 19.0 software (IBM Corp., Armonk, NY) (Canadian Task Force Classification II-2). RESULTS: The WB group had fewer and less severe perineal lacerations despite increased macrosomia. The non-WB group had increased maternal factors (age <20 years, third- to fourth-degree perineal tears, excessive blood loss) and neonatal factors (Apgar scores <7 at 5 minutes and neonatal intensive care unit admission). No significant difference was identified between the birth groups for maternal age >35 years, primiparous status, maternal fever, maternal puerperal infection, maternal intensive care unit admission, low birth weight, neonatal resuscitation, and neonatal intensive care unit admission <28 days of life. CONCLUSIONS: A low-risk maternal cohort of WBs (1716) managed by midwives had equivalent or improved neonatal outcomes compared with a low-risk maternal cohort of land or traditional births (21 320) managed by midwives and other maternity providers.

Perineal outcome following educational intervention: a retrospective audit of primiparous women.

The management of vaginal delivery appears to offer an opportunity to reduce the morbidity of pelvic floor dysfunction (PFD) which is very common in the postpartum period. Research by the authors suggests that an episiotomy is protective against PFD, in particular urinary incontinence. The aim of this subsequent audit was to see if educational intervention can alter the common medical practice of episiotomy and in turn reduce postpartum PFD. Nine hundred and fifty four primiparous women with a non-instrumental vaginal delivery were included, of which 30% had an intact perineum, 51% a spontaneous tear and 19% an episiotomy. The intervention was a teaching session by the Head of Urogynaecology encompassing the anatomy, the impact of a vaginal delivery on PFD, in addition to local and international research. Whilst no significant difference was noted overall in the episiotomy rates as a result of the educational intervention (p = .17), significant differences were noted with the different accoucheur types. Where the accoucheur was an obstetrician or obstetrics registrar, the episiotomy rates increased from 56% to 70% (p < .01); where the midwife was the accoucheur the episiotomy rate changed minimally (11-18%, respectively; p = .27). This demonstrates that feedback about the provider's own practice patterns can change the behaviour to conform with the agreed upon standards. Impact Statement What is already known on this subject? Pelvic floor dysfunction (PFD) is the most common complication of childbirth, affecting approximately 85% of Australian women following a vaginal delivery. A link has been made between the perineal outcome and PFD, which has a significant impact on the quality of life. Previous research suggests that the management of a vaginal delivery offers an opportunity to reduce its morbidity, with an episiotomy being protective. However, there is a wide variation in the use of episiotomy which ranges from 9% to 100%. What the results of this study add? The literature suggests that the strongest factor associated with the episiotomy rates arises from differences in the attitude and training. Consequently, this study explored whether an educational intervention can change the common medical practice of episiotomy and in turn reduce postpartum PFD. What are the implications of these findings for clinical practice and/or further research? No significant difference was noted overall in the episiotomy rates as a result of the educational intervention, however, the response to the educational intervention was varied among the different types of accoucheurs with the obstetricians, obstetric registrars and student midwives significantly increasing their rate of episiotomy, whilst the midwives demonstrated no significant change. This suggests that there are contributing factors which may include past education and experience; this is an area for further research.

Labour outcomes in caseload midwifery and standard care: a register-based cohort study.

BACKGROUND: Research on caseload midwifery in a Danish setting is missing. This cohort study aimed to compare labour outcomes in caseload midwifery and standard midwifery care. METHODS: A historical register-based cohort study was carried out using routinely collected data about all singleton births 2013-2016 in two maternity units in the North Denmark Region. In this region, women are geographically allocated to caseload midwifery or standard care, as caseload midwifery is only available in some towns in the peripheral part of the uptake areas of the maternity units, and it is the only model of care offered here. Labour outcomes of 2679 all-risk women in caseload midwifery were compared with those of 10,436 all-risk women in standard midwifery care using multivariate linear and logistic regression analyses. RESULTS: Compared to women in standard care, augmentation was more frequent in caseload women (adjusted odds ratio (aOR) 1.20; 95% CI 1.06-1.35) as was labour duration of less than 10 h (aOR 1.26; 95% CI 1.13-1.42). More emergency caesarean sections were observed in caseload women (aOR 1.17; 95% CI 1.03-1.34), but this might partly be explained by longer distance to the maternity unit in caseload women. When caseload women were compared to women in standard care with a similar long distance to the hospital, no difference in emergency caesarean sections was observed (aOR 1.04; 95% CI 0.84-1.28). Compared to standard care, infants of caseload women more often had Apgar ≤7 after 5 min. (aOR 1.57; 95% CI 1.11-2.23) and this difference remained when caseload women were compared to women with similar distance to the hospital. For elective caesarean sections, preterm birth, induction of labour, dilatation of cervix on admission, amniotomy, epidural analgesia, and instrumental deliveries, we did not obseve any differences between the two groups. After birth, caseload women more often experienced no laceration (aOR 1.17; 95% CI 1.06-1.29). CONCLUSIONS: For most labour outcomes, there were no differences across the two models of midwifery-led care but unexpectedly, we observed slightly more augmentation and adverse neonatal outcomes in caseload midwifery. These findings should be interpreted in the context of the overall low intervention and complication rates in this Danish setting and in the context of research that supports the benefits of caseload midwifery. Although the observational design of the study allows only cautious conclusions, this study highlights the importance of monitoring and evaluating new practices contextually.

Does midwife experience affect the rate of severe perineal tears?

BACKGROUND: Our aim was to study whether midwife experience affects the rate of severe perineal tears (3rd and 4th degree). METHODS: A retrospective cohort study of all women with term vertex singleton pregnancies, who underwent normal vaginal deliveries, in a single tertiary hospital, between 2011 and 2015, was performed. Exclusion criteria were instrumental deliveries and stillbirth. All midwives used a "hands on" technique for protecting the perineum. The midwife experience at each delivery was calculated as the time interval between her first delivery and current delivery. A comparison was performed between deliveries in which midwife experience was less than 2 years (inexperienced), between 2 and 10 years (moderately experienced), and more than 10 years (highly experienced). A multivariate regression analysis was performed to assess the association between midwife experience and the incidence of severe perineal tears, after controlling for confounders. RESULTS: Overall, 15 146 deliveries were included. Severe perineal tears were diagnosed in 51 (0.33%) deliveries. Women delivered by inexperienced midwives had a higher rate of severe perineal tears compared with women delivered by highly experienced midwives (0.5% vs 0.2%, respectively, P=.024). On multivariate regression analysis, midwife experience was independently associated with a lower rate of severe perineal tears, after controlling for confounding factors. Each additional year of experience was associated with a 4.7% decrease in the risk of severe perineal tears (adjusted OR 0.95 [95% CI 0.91-0.99, P=.03). CONCLUSION: More experienced midwives had a lower rate of severe perineal tears, and may be preferred for managing deliveries of women at high risk for such tears.

Birthing postures and birth canal lacerations.

OBJECTIVE: This study was performed to assess the differences in the birth canal lacerations following the lateral and fours posture deliveries compared with those following the supine posture deliveries. METHODS: We examined the birth canal lacerations of our "low risk" pregnant women under the midwife-led delivery care at Japanese Red Cross Katsushika Maternity Hospital between April 2006 and March 2015. RESULTS: There were 3826, 1754 and 719 women who delivered with supine, lateral and fours postures. The rate of no laceration in the women who delivered with lateral posture was significant lower than that in the women who delivered with supine posture (OR 0.630, 95% CI 0.56-0.71, p < 0.01); however, the incidence of perineal laceration in the women who delivered with lateral posture was significant lower than that in the women who delivered with supine posture (OR 0.856, 95% CI 0.76-0.90, p < 0.01). The incidence of perineal laceration of third- or fourth-degree in the women who delivered with fours posture was significant higher than that in the women who delivered with supine posture (OR 2.28, 95% CI 1.2-4.2, p < 0.01). CONCLUSION: The current results may be to help for self-determination of birthing postures in prenatal women.

Adding Injury to Insult: A National Analysis of Combat Sport-Related Facial Injury.

OBJECTIVES/HYPOTHESIS: To estimate the incidence of patients presenting to emergency departments (EDs) for facial trauma sustained from participation in combat sports and evaluate injury patterns and patient demographics. METHODS: The National Electronic Injury Surveillance System (NEISS) was evaluated for facial injuries from wrestling, boxing, and martial arts leading to ED visits from 2008 to 2013. Relevant entries were examined for injury mechanism, location, type, as well as other patient characteristics. RESULTS: There were 1143 entries extrapolating to an estimated 42 395 ED visits from 2008 to 2013. Injury rates for boxing, marital arts, and wrestling were, respectively, 44, 56, and 120 injuries per 100 000 participants. Males comprised the majority (93.7%). A plurality of injuries involved lacerations (46.0%), followed by fractures (26.2%) and contusions/abrasions (19.3%). The proportion of fractures was highest among boxers (36.9%). Overall, the most common mechanisms of injury were punching, kicking, and head butting. CONCLUSIONS: The significant number of ED visits resulted from combat sports facial trauma, reinforcing the importance of familiarity with injury patterns among practitioners managing facial trauma. As most injuries involve individuals younger than 19 despite guidelines suggesting children and adolescents avoid combat sports, these findings may be used for patient education and encouragement of the use of personal protective equipment. Furthermore, injury patterns reported in this analysis may serve as an adjunct for enhancing clinical history taking and physical examination.

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.

Prevalence of Perineal Lacerations in Women Giving Birth at Midwife-Led Birth Centers in Japan: A Retrospective Descriptive Study.

INTRODUCTION: Perineal lacerations during birth can cause ongoing physical, psychological, and social problems. However, the prevalence of lacerations following normal spontaneous vaginal birth in women with low-risk pregnancies is unknown. We investigated the prevalence of perineal lacerations and factors associated with lacerations among low-risk Japanese women who had normal spontaneous vaginal births. METHODS: Pregnant women who were cared for between January 1, 2008, and June 30, 2011, in 3 midwife-led birth centers in Tokyo, Japan, where invasive medical interventions are rarely applied, were included. We investigated the prevalence of perineal lacerations and conducted univariate and multivariate analyses on the relationship between the prevalence of lacerations and selected maternal and neonatal characteristics. RESULTS: A total of 1881 pregnant women had initial antenatal care at one of the 3 study sites. Of these, 1521 were eligible for inclusion. Intact perineum rates were 49.5% (209/422) and 69.9% (768/1099) in nulliparous and multiparous women, respectively. First-degree lacerations occurred in 36.7% (155/422) of nulliparous women and 27.1% (298/1099) of multiparous women, and second-degree lacerations occurred in 13.5% (57/422) of nulliparous women and 3.0% (33/1099) of multiparous women. One multiparous woman experienced a third-degree laceration (0.1%). No women suffered fourth-degree or cervical lacerations. Logistic regression analyses showed that older age (≥ 35 years), the hands-and-knees position, and using a birthing chair during birth increased the risk of perineal laceration both in nulliparous and in multiparous women. In addition, waterbirths increased the risk of perineal laceration in multiparous women. DISCUSSION: In normal spontaneous vaginal births among a low-risk population, it is possible to avoid episiotomy and achieve a high rate of intact perineum, with few second-degree and third-degree lacerations.

Suicide risk among perinatal women who report thoughts of self-harm on depression screens.

OBJECTIVE: To estimate the incidence and clinical significance of suicidal ideation revealed during perinatal depression screening and estimate the associated suicide risk. METHODS: Retrospective cohort study of women completing the Edinburgh Postnatal Depression Scale at 24-28 weeks of gestation and 6 weeks postpartum through a suburban integrated health system with approximately 5,000 annual deliveries on two hospital campuses. Suicidal ideation on the Edinburgh Postnatal Depression Scale and prediction of suicide risk were examined through multivariable modeling and qualitative analysis of clinical assessments. RESULTS: Among 22,118 Edinburgh Postnatal Depression Scale questionnaires studied, suicidal ideation was reported on 842 (3.8%, 95% confidence interval [CI] 3.5-4.1%) and was positively associated with younger maternal age (antepartum mean age 30.9 compared with 31.9 years, P=.001), unpartnered relationship status (antepartum 29.5% compared with 16.5%, P<.001 and postpartum 25.0% compared with 17.5%, P<.01), non-Caucasian race (antepartum 62.1% compared with 43.8%, P<.001 and postpartum 62.4% compared with 45.2%, P<.001), non-English language (antepartum 11.0% compared with 6.6%, P<.001 and postpartum 12.4% compared with 7.7%, P<.01), public insurance (antepartum 19.9% compared with 12.5%, P<.001 and postpartum 18.2% compared with 14.2%, P<.001), and preexisting psychiatric diagnosis (antepartum 8.4% compared with 4.2%, P<.001 and postpartum 12.0% compared with 5.8%, P<.001). Multivariable antepartum and postpartum models retained relationship status, language, relationship status by language interaction, and race; the postpartum model also found planned cesarean delivery negatively associated with suicidal ideation risk (odds ratio [OR] 0.56, 95% CI 0.36-0.87) and severe vaginal laceration positively associated with suicidal ideation risk (OR 2.1, 95% CI 1.00-4.40). A qualitative study of 574 women reporting suicidal ideation indicated that 330 (57.5%, 95% CI 53.5-61.5%) experienced some degree of suicidal thought. Six patients (1.1%, 95% CI 0.2-1.9%) demonstrated active suicidal ideation with plan, intent, and access to means. Within this highest risk group, three patients reported a suicide attempt within the perinatal period. CONCLUSION: Among perinatal women screened for depression, 3.8% reported suicidal ideation, but only 1.1% of this subgroup was at high risk for suicide. These findings support the need for systematic evaluation of those who report suicidal ideation to identify the small subset requiring urgent evaluation and care.
