Int J Gynaecol Obstet 2024. [PMID: 38234163 DOI: 10.1002/ijgo.15374] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/04/2023] [Revised: 12/22/2023] [Accepted: 01/02/2024] [Indexed: 01/19/2024]
Abstract
OBJECTIVE To compare maternal and fetal outcomes between early (<2 h) and delayed (>2 h) vacuum extraction (VE) deliveries. METHODS We performed a retrospective cohort study in a single, university-affiliated medical center (2014-2021). We included term singleton pregnancies delivered by VE, allocated into one of two groups according to second stage duration: <2 h or >2 h. Primary outcome was maternal composite adverse outcome (included chorioamnionitis, 3-4 degree lacerations, and postpartum hemorrhage [PPH]). RESULTS We included 2521 deliveries: 2261 (89.6%) with early VE and 260 (10.4%) with delayed VE. Study groups' characteristics were not different, except of parity. Maternal composite outcome almost reached a significance (P = 0.054) comparing between the groups. Comparing second stage length up to 2 h versus more, there was similar rate of advance maternal lacerations. However, extending the second stage to more than 3 h was associated with third degree lacerations compared to 2-3 h (9.8% vs 3%, P = 0.011). There were significantly more PPH events in the later VE group (P = 0.004), but the need for blood transfusions was similar. The rates of 5 min Apgar score ≤7 (P = 0.001) and umbilical artery pH <7.0 were significantly higher in group 2 compared with group 1. The effect was much more pronounced when second stage was >3 h. After conducting multiregression analysis, the results became insignificant. CONCLUSION Our study suggests that VE performed in the late second stage of labor, up to 3 h, is safe as VE performed in the early stages regarding maternal and neonatal outcomes. Extra caution is needed with extended second stage to more than 3 h.

Abstract
INTRODUCTION AND HYPOTHESIS The objective was to identify modifiable risk factors for obstetric anal sphincter injury (OASI) in primiparous women. METHODS This was a retrospective cohort study of primiparous women with a singleton vaginal delivery. Main outcome measures were incidence of OASI and odds ratios for possible risk factors: maternal age, body mass index and height, fetal birthweight and head circumference, gestational age, epidural analgesia, mediolateral episiotomy, and instrumental deliveries. Univariate and multivariate logistic regressions were performed using forward methods for variable selection. RESULTS Of 19,786 primiparous women with a singleton vaginal delivery, 369 sustained an OASI (1.9%). Risk factors were identified: vacuum extraction (adjusted OR 2.06, 95% CI, 1.59-2.65, p < 0.001), increased fetal weight (aOR 1.06, 95% CI, 1.02-1.11, p = 0.002, per 100-g increments); head circumference (aOR 1.24, 95% CI, 1.13-1.35, p < 0.001, per 1-cm increments); gestational week (aOR 1.11, 95% CI, 1.02-1.2, p = 0.012, per week). Protective factors: mediolateral episiotomy (aOR 0.75, 95% CI, 0.59-0.94, p = 0.013) particularly in vacuum deliveries (aOR 0.50, 95% CI, 0.29-0.97, p = 0.040); epidural analgesia (aOR 0.64, 95% CI, 0.48-0.84, p = 0.001); maternal height ≥157 cm (aOR 0.97, 95% CI, 0.96-0.98, p = 0.006, risk decreases by 2.6% per 1 cm increase in height). CONCLUSIONS Mediolateral episiotomy was protective against OASI in both spontaneous and instrumental deliveries of primiparae. Increased fetal weight and large fetal head circumference, particularly in short women, were significant risk factors. These findings support the performance of ultrasound to acquire updated fetal measures before admission to the labor ward.

Risk factors associated with third- and fourth-degree perineal lacerations in singleton vaginal deliveries: a comprehensive United States population analysis 2016-2020. J Perinat Med 2023; 51:1006-1012. [PMID: 37261912 DOI: 10.1515/jpm-2023-0127] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/26/2023] [Accepted: 04/25/2023] [Indexed: 06/03/2023]
Abstract
OBJECTIVES Perineal lacerations are a common complication of vaginal birth, affecting approximately 85 % of patients. Third-and fourth-degree perineal lacerations (3/4PL) remain a significant cause of physical and emotional distress. We aimed to perform an extensive assessment of potential risk factors for 3/4PL based on a comprehensive and current US population database. METHODS Retrospective population-based cohort analysis based on the US Centers for Disease Control and Prevention Natality Live Birth online database between 2016-2020. Baseline characteristics were compared between women with 3/4PL and without 3/4PL by using Pearson's Chi-squared test with statistical significance set at p<0.05. Bonferroni correction was used to account for multiple comparisons. Multivariable logistic regression was performed to evaluate the association between a variety of potential risk factors and the risk of 3/4P. RESULTS Asians/Pacific Islanders had the highest risk of 3/4PL (2.6 %, aOR 1.74). Gestational hypertension and preeclampsia were associated with increased risk of 3/4PL (aOR 1.28 and 1.34, respectively), as were both pre-gestational and gestational diabetes (aOR 1.28 and 1.46, respectively). Chorioamnionitis was associated almost double the risk (aOR 1.86). Birth weight was a major risk factor (aOR 7.42 for greater than 4,000 g), as was nulliparity (aOR 9.89). CONCLUSIONS We identified several maternal, fetal, and pregnancy conditions that are associated with an increased risk for 3/4PL. As expected, nulliparity and increased birth weight were associated with the highest risk. Moreover, pregestational and gestational diabetes, hypertensive disorders of pregnancy, Asian/Pacific Islander race, and chorioamnionitis were identified as novel risk factors.

Abstract
PURPOSE The aim was to investigate if intrapartum monitoring with cardiotocography (CTG) in combination with ST analysis (STAN) results in an improved perinatal outcome. METHODS We performed a two-center randomized trial. 1013 women with term fetuses in cephalic presentation entered the trial. If a CTG showed intermediate or pathological abnormalities, they were offered fetal blood sampling (FBS) and inclusion if the pH value was above 7.25. They were randomized to either CTG + FBS or CTG + STAN. The primary outcome was neonatal metabolic acidosis, defined as umbilical cord arterial blood pH below 7.05, and base excess equal to or below -10. The secondary outcomes included operative vaginal delivery for fetal distress. RESULTS The rate of metabolic acidosis was 0.8% in the CTG + FBS group and 1.5% in women in the CTG + STAN (P = 0.338). More women in the CTG + STAN group delivered by operative vaginal delivery (25.6% vs 33.5%, P = 0.006). Significantly fewer women in the CTG + STAN group had three to five (28.8% vs 11.0%, P = < 0.001) and six to ten fetal blood samples taken (3.4% vs 0.4%, P = < 0.001). CONCLUSION CTG + STAN did not reduce the incidence of neonatal metabolic acidosis compared to CTG + FBS. CTG + STAN was, however, associated with an increased risk of operative vaginal delivery and a reduced use of FBS. If STAN is used for fetal surveillance, we recommend that it is combined with other methods, such as FBS, for confirmation of the need for operative delivery. CLINICALTRIALS gov ID: NCT01699646.

Abstract
INTRODUCTION AND HYPOTHESIS Obstetric anal sphincter injury (OASI) is a debilitating complication of vaginal delivery. The aim of this study was to identify risk factors for OASI in women with a previous vaginal delivery. We further attempted to detect specific risk factors for severe OASI in this subgroup. METHODS We conducted a retrospective cohort study between 2003 and 2019. The study group included women who had a singleton, live, vertex, vaginal delivery at term and who also had at least one previous vaginal delivery. The control group included women with at least one previous vaginal delivery without OASI. General medical history, obstetric history, and ante-, intra- and post-partum data were collected and compared between groups. RESULTS Following implementation of the inclusion criteria, 79,176 women were included. Allocation to study groups was according to OASI occurrence: 135 patients (0.2%) had a third- or fourth-degree perineal tear, while 79,041 patients (99.8%) had no such injury. Multivariate analysis revealed that one previous vaginal delivery, birthweight ≥ 3900 g (90th percentile), vacuum-assisted vaginal delivery and episiotomy were associated with increased risk of OASI. Comparison of more severe OASI (3C and 4th-degree) cases to the control group showed similar results with the addition of prolonged second stage and younger age to risk factors associated with severe OASI while episiotomy was no longer significant. CONCLUSION In women with a previous vaginal delivery, one vs. two or more previous vaginal deliveries, increased birthweight, vacuum-assisted vaginal delivery and episiotomy are risk factors for OASI.

Abstract
Objectives Our study sought to assess the maternal and neonatal outcomes of operative vaginal deliveries (OVDs) at Sultan Qaboos University Hospital (SQUH). We assessed the proportion of OVDs along with the proportion of maternal and neonatal outcomes of kiwi OmniCup vacuum, metal cup vacuum, and forceps deliveries. Methods We conducted a retrospective cohort study in the Obstetrics and Gynecology Department at SQUH from June 2015 to March 2018. The hospital information system was utilized to obtain records of all women who delivered at SQUH by vacuum or forceps during the study period. We collected data on maternal demographics, maternal and neonatal outcomes, and total number of deliveries. Results During the study period, 3.8% of deliveries were OVDs. The most common instrument used was the Kiwi OmniCup vacuum device. No significant difference was found between the type of tears and instrument used except perineal tears (p = 0.003), which was seen more in the vacuum group, particularly Kiwi OmniCup. Neonatal birth weight (p = 0.046) was significantly higher in the metallic vacuum cup group. Thirty-one neonates (6.6%) were admitted to the neonatal intensive care unit, and most were born using Kiwi OmniCup vacuum (67.7%). Conclusions OVD is an ideal alternative to cesarean section with fewer maternal and neonatal complications in women who cannot deliver spontaneously if performed by a well-trained obstetrician.

Abstract
OBJECTIVE To determine the relationship between age at first delivery and subsequent risk of pelvic organ prolapse. STUDY DESIGN We performed a retrospective cross-sectional study using the National Health and Nutrition Examination Survey data from 2005 to 2012. Our primary outcome was self-reported prolapse. Survival analyses and Cox proportional hazard models were used to estimate parous women's risks of reporting prolapse in terms of time since first delivery, adjusting for parity, body mass index, prior hysterectomy, ethnicity, and education. We performed subgroup analyses on women with at least 1 vaginal delivery and those with only cesarean deliveries. RESULTS The survey-weighted prevalence of prolapse was 2.82%. A total of 6203 women, 79% of all parous women surveyed, reported age at first delivery. Kaplan-Meier curves were different for women based on age at first delivery (P = 0.034). For each year increase in age at first delivery, there was a 6% increase in the rate of developing prolapse (adjusted hazard ratio, 1.06; 95% confidence interval, 1.01-1.11; P = 0.011). Compared with a woman who was 20 years at her first delivery, someone who was 30 years had 1.79 times the risk, while at 40 years the risk was 3.21 times. Among women with at least 1 vaginal delivery, the same relationship was found (adjusted hazard ratio, 1.06; 95% confidence interval, 1.01-1.12; P = 0.019). However, this was not significant for women with only cesarean deliveries (P = 0.367). CONCLUSIONS Older age at the time of first delivery was associated with a higher risk of subsequent prolapse. These results should be interpreted with caution given the limitations of cross-sectional survey data.

Abstract
OBJECTIVE To evaluate the effects of a quality improvement initiative regarding the administration of antibiotics at the time of obstetric anal sphincter injury (OASIS) repair. METHODS At University of Michigan-a tertiary care center in Ann Arbor, MI, USA, we implemented a quality improvement intervention aimed at administering a single dose of broad-spectrum antibiotics at the time of OASIS repair. Best practice recommendations and reminders were presented to the department. Cefazolin plus metronidazole or clindamycin plus gentamycin were the recommended antibiotics. The effects of this intervention were assessed based on a chart review of deliveries between January 4, 2014 and February 13, 2019, which included patient data both pre-initiative and post-initiative to compare the prevalence of antibiotic use at the time of OASIS repair. RESULTS Recommended antibiotic use increased from 0.3% (1/372) pre-initiative to 75.7% (106/140) post-initiative (P < 0.001), and any antibiotic use increased from 6.5% (24/372) to 82.9% (116/140, P < 0.001). The proportion of cases complicated by wound infection/breakdown decreased by 55% after the quality improvement intervention (3.2% pre-intervention vs 1.4% post-intervention, P = 0.22). CONCLUSION Following a departmental quality improvement intervention aimed at increasing antibiotic administration at the time of OASIS repair, antibiotic use increased 13-fold. Although underpowered to detect a significant difference in wound complications, our study showed a clinically meaningful decrease in wound infection/breakdown with antibiotic administration.

Abstract
PURPOSE Nulliparity and operative vaginal delivery are established risk factor for obstetric anal sphincter injury (OASI). However, risk factors for OASIS occurrence among parous women delivering vaginally are not well-established. We aimed to study the risk factors for OASI occurrence among parous women. METHODS A retrospective study including all parous women who delivered vaginally at term during 2011-2019 at a university hospital. Deliveries of parous women with OASI were compared to deliveries without OASI. The risk factors associated with OASI were investigated. RESULTS Overall, 35,397 women were included in the study with an OASI rate of 0.4% (n = 144). A higher rate of only one previous vaginal delivery was noted in the OASI group (78.5% vs. 46.4%, OR [95% CI] 4.20, 2.82-6.25, p < 0.001). The rate of vacuum-assisted deliveries was comparable between the study groups. The median birth weight was higher among the OASI group (3566 vs. 3300 g, p < 0.001), as was the rate of macrosomic neonates (19.4% vs. 5.5%, OR [95% CI] 4.15, 2.74-6.29, p < 0.001). On multivariate logistic regression analysis, only two factors were independently positively associated with the occurrence of OASI: a history of only one previous vaginal delivery (adjusted OR [95% CI] 4.34, 2.90-6.49, p = 0.001), and neonatal birth-weight (for each 500 g increment) (adjusted OR [95% CI] 2.51, 1.84-3.44, p < 0.001). CONCLUSIONS Among parous women, the only factors found to be independently positively associated with OASI were the order of parity and neonatal birth-weight. Vacuum-assisted delivery was not associated with an increased risk of OASI among parous women.

Abstract
Rectovaginal fistula (RVF), defined as any abnormal connection between the rectum and the vagina, is a complex and debilitating condition. RVF can occur for a variety of reasons, but frequently develops following obstetric injury. Patients with suspected RVF require thorough evaluation, including history and physical examination, imaging, and objective evaluation of the anal sphincter complex. Prior to attempting repair, sepsis must be controlled and the tract allowed to mature over a period of 3 to 6 months. All repair techniques involve reestablishing a healthy, well-vascularized rectovaginal septum, either through reconstruction with local tissue or tissue transfer via a pedicled flap. The selection of a specific repair technique is determined by the level of the fistula tract and the status of the anal sphincter. Despite best efforts, recurrence is common and should be discussed with patients prior to repair. As the ultimate goal of RVF repair is to minimize symptoms and maximize quality of life, patients should help to direct their own care based on the risks and benefits of available treatment options.

Abstract
Falandry and Martius’ techniques were used firstly for vesico-vaginal fistulas with satisfying long-term functional results. The same techniques are feasible and safe for rectovaginal fistula repair. In this case series, patients had an improvement of their self-image and health-related quality of life. Temporary colostomy is recommended before this reconstructive surgery.
Introduction Rectovaginal fistula (RVF) is defined as an abnormal communication between the anterior wall of the rectum and the posterior wall of the vagina. Many surgical techniques have been described in the treatment of RVF. However, none has proved its superiority. The aim of the study was to evaluate the functional results of surgical treatment of RVF using Martius and Falandry techniques in order to assess the feasibility and the efficacy of these techniques which were first described for vesico-vaginal fistulas. Methods The study was a retrospective case series conducted in a single centre: Department of general surgery at Ibn Sina University Hospital in Rabat. We included patients with rectovaginal fistula consecutively recruited from 2011 to 2014. 10 patients developed RVF after surgery for rectal cancer (9 cases), uterine cancer (1 case). One patient had RVF for ano-rectal malformation. Colostomy was performed before the treatment of fistula in 9 cases (82 %). They underwent surgical treatment using Falandry (8 patients) and Martius techniques (3 patients) performed by an experienced urologist surgeon. Results No postoperative complications were recorded. Time to discharge was postoperative day 3–4. There was a complete disappearance of RVF in 8 patients (72.7 % of cases), relapse in 2 cases (18 %), and failure in one case (9%). The average follow-up was 12.6 +/-10 months. Functionally, no long-term cases of fecal incontinence or dyspareunia were noted. Conclusion The choice of surgical technique in the treatment of RVF remains difficult because of poor literature data and absence of consensus. RVF repair results either by Martius or Falandry techniques are encouraging with low morbidity.

Abstract
BACKGROUND Vacuum and forceps assisted vaginal deliveries are reported to increase the incidence of postpartum infections and maternal readmission to hospital compared to spontaneous vaginal delivery. Prophylactic antibiotics may be prescribed to prevent these infections. However, the benefit of antibiotic prophylaxis for operative vaginal deliveries is still unclear. This is an update of a review last published in 2017. OBJECTIVES To assess the effectiveness and safety of antibiotic prophylaxis in reducing infectious puerperal morbidities in women undergoing operative vaginal deliveries including vacuum or forceps delivery, or both. SEARCH METHODS For this update, we searched Cochrane Pregnancy and Childbirth's Trials Register, ClinicalTrials.gov, the WHO International Clinical Trials Registry Platform (ICTRP) (5 July 2019), and reference lists of retrieved studies. SELECTION CRITERIA All randomised controlled trials comparing any prophylactic antibiotic regimens with placebo or no treatment in women undergoing vacuum or forceps deliveries were eligible. Participants were all pregnant women without evidence of infections or other indications for antibiotics of any gestational age. Interventions were any antibiotic prophylaxis (any dosage regimen, any route of administration or at any time during delivery or the puerperium). DATA COLLECTION AND ANALYSIS Two review authors assessed trial eligibility and risk of bias. Two review authors extracted the data independently using prepared data extraction forms. Any discrepancies were resolved by discussion and a consensus reached through discussion with all review authors. We assessed methodological quality of the two included studies using the GRADE approach. MAIN RESULTS Two studies, involving 3813 women undergoing either vacuum or forceps deliveries, were included. One study involving 393 women compared the antibiotic intravenous cefotetan after cord clamping compared with no treatment. The other study involving 3420 women compared a single dose of intravenous amoxicillin and clavulanic acid with placebo using 20 mL of intravenous sterile 0.9% saline. The evidence suggests that prophylactic antibiotics reduce superficial perineal wound infection (risk ratio (RR) 0.53, 95% confidence interval (CI) 0.40 to 0.69; women = 3420; 1 study; high-certainty evidence), deep perineal wound infection (RR 0.46, 95% CI 0.31 to 0.69; women = 3420; 1 study; high-certainty evidence) and probably reduce wound breakdown (RR 0.52, 95% CI 0.43 to 0.63; women = 2593; 1 study; moderate-certainty evidence). We are unclear about the effect on organ or space perineal wound infection (RR 0.11, 95% CI 0.01 to 2.05; women = 3420; 1 study) and endometritis (average RR 0.32, 95% CI 0.04 to 2.64; 15/1907 versus 30/1906; women = 3813; 2 studies) based on low-certainty evidence with wide CIs that include no effect. Prophylactic antibiotics probably lower serious infectious complications (RR 0.44, 95% CI 0.22 to 0.89; women = 3420; 1 study; high-certainty evidence). They also have an important effect on reduction of confirmed or suspected maternal infection. The two included studies did not report on fever or urinary tract infection. It is unclear, based on low-certainty evidence, whether prophylactic antibiotics have any impact on maternal adverse reactions (RR 2.00, 95% CI 0.18 to 22.05; women = 2593; 1 study) and maternal length of stay (MD 0.09 days, 95% CI -0.23 to 0.41; women = 393; 1 study) as the CIs were wide and included no effect. Prophylactic antibiotics slightly improve perineal pain and health consequences of perineal pain and probably reduce costs. Prophylactic antibiotics did not have an important effect on dyspareunia (difficult or painful sexual intercourse) or breastfeeding at six weeks. Antibiotic prophylaxis may slightly improve maternal hospital re-admission and maternal health-related quality of life. Neonatal adverse reactions were not reported in any included trials. AUTHORS' CONCLUSIONS Prophylactic intravenous antibiotics are effective in reducing infectious puerperal morbidities in terms of superficial and deep perineal wound infection or serious infectious complications in women undergoing operative vaginal deliveries without clinical indications for antibiotic administration after delivery. Prophylactic antibiotics slightly improve perineal pain and health consequences of perineal pain, probably reduce the costs, and may slightly reduce the maternal hospital re-admission and health-related quality of life. However, the effect on reduction of endometritis, organ or space perineal wound infection, maternal adverse reactions and maternal length of stay is unclear due to low-certainty evidence. As the evidence was mainly derived from a single multi-centre study conducted in a high-income setting, future well-designed randomised trials in other settings, particularly in low- and middle-income settings, are required to confirm the effect of antibiotic prophylaxis for operative vaginal delivery.

Abstract
Several studies have investigated the importance of maternal, fetal factors and intrapartum characteristics in predicting severe perineal lacerations. The purpose of the present systematic review is to accumulate current evidence and provide estimated effect sizes for the various risk factors described. We reviewed Medline, Scopus, Clinicaltrials.gov, EMBASE, Cochrane Central Register of Controlled Trials CENTRAL and Google Scholar for published studies in the field for observational studies as well as randomized controlled trials. Two researchers independently assessed the included studies and documented outcomes. Data extraction was performed using a modified data form that was based in Cochrane`s data collection form for intervention reviews for RCTs and non-RCTs. Forty-three articles were selected for inclusion in the present systematic review. The analyzed population reached 716,031 parturient of whom 22,280 (3,1%) sustained third- and fourth-degree perineal lacerations. Several risk factors were identified. Instrumental delivery [RR 3.38 (2.21, 5.18)], midline episiotomy [RR 2.88 (1.79, 4.65)] and a persistent occiput posterior position [RR 2.73 (2.08, 3.58)] were associated with the higher risk of developing severe perineal lacerations. Mediolateral episiotomy did not increase, but was also not protective against perineal lacerations [RR 1.55 (0.95, 2.53)]. Several factors contribute to the development of severe perineal lacerations. The present meta-analysis presents accumulated data that may help physicians estimate risks and provide appropriate patient counseling.

Abstract
PURPOSE Since every obstetric surgical procedure requires gaining informed consent from patient, we have set out to evaluate whether such requirement also applies to episiotomy. MATERIAL AND METHODS To that end, we have conducted a thorough search of relevant scientific literature on multidisciplinary databases (Scopus, PubMed, PubMed, Central, Research Gate, Google Scholar) and articles that were published from 1989 to March 2019. The search keys used were: "episiotomy," "informed consent," "complications," "malpractice." RESULTS The sources that we have ultimately drawn upon, whilst acknowledging the need for a targeted informed consent for episiotomy, do not deal with the specifics of what such consent should include, in terms of information provided and related aspects. Therefore, the authors have laid out an episiotomy-targeted consent form, drawing upon opinions and indications from scientific societies and institutions, in order to properly reflect and document the patient's acceptance or refusal of the procedure. CONCLUSIONS Valid consent documentation may well prove instrumental in staving off or reducing complications, malpractice and liability, and in order to safeguard health care operators from obstetric malpractice allegations.

Abstract
BACKGROUND In view of the reported increase in obstetric anal sphincter injuries, the objective of this study was to evaluate the incidence of such injuries over time and the associated risk and protective factors. METHODS This was a retrospective cohort study from a national database of 168 137 primiparous women with term, singleton, cephalic, vaginal delivery between 2008 and 2014. The main outcome measure was obstetric anal sphincter injury. A multivariate regression model was used to identify risk and protective factors. RESULTS Age >19 years, birthweight >4000 g, and operative vaginal delivery were independent risk factors for obstetric anal sphincter injuries. Mediolateral episiotomy increased the risk for obstetric anal sphincter injuries in spontaneous vaginal birth (number needed to harm 333), whereas it was protective in vacuum delivery (number needed to treat 50). From 2008 to 2014, there was an increase in the rate of obstetric anal sphincter injuries (2.1% vs 3.1%, P < .01), vacuum deliveries (12.1% vs 12.8%, P < .01), and cesarean delivery after labor (17.1% vs 19.4%, P < .01), while forceps deliveries (0.4% vs 0.1%, P < .01) and episiotomy rate decreased (35.9% vs 26.4%, P < .01). CONCLUSIONS Episiotomy may be a risk or protective factor depending on the type of episiotomy and the clinical setting in which it is used. Our study supports a restrictive use of mediolateral episiotomy in spontaneous vaginal deliveries. In vacuum deliveries mediolateral episiotomy may help prevent obstetric anal sphincter injuries.

Abstract
Introduction: The aim of this retrospective study was to examine the rates of perineal tears during childbirth in Slovenian maternity hospitals in the period from 2013 to 2015.Methods: A causal non-experimental method of quantitative empirical approach was conducted. Data were pooled from the Slovenian National Perinatal Information System and analysed for the period of 2013 to 2015. Data analysis was performed with the use of frequency distribution of attributive variables and the basic descriptive statistics of numerical variables.Results: The incidence of perineal trauma during childbirth in all the 14 maternity hospitals varies from the "perineum without injury" to the "fourth degree perineal tear". Overall, 26.1 % of women sustained a first degree perineal tear, whereas 4.8 % of women had a second degree perineal tear. Severe perineal trauma included 0.8 % of third degree tears and 0.1 % of fourth degree tears.Discussion and conclusion: Perineal trauma varies between Slovenian maternity hospitals. Women who have sustained tears that cut into their bowels may face serious health problems and should be given relevant advice regarding the state of their pelvic floor after childbirth. It is of great importance to appropriately recognise the severity of the perineal trauma. Moreover, health professionals should be familiar with the perineal trauma classification and the factors that may cause the perineum to tear during childbirth.

Abstract
OBJECTIVES The aim of the study was o determine whether variations exist between races/ethnicities in perineal laceration at first vaginal delivery. METHODS We assessed first vaginal deliveries greater than 35 weeks gestation, for a four-year period, in our diverse urban healthcare system. Predictor variable was race/ethnicity with outcome variable of none, first-, second-, third-, or fourth-degree perineal laceration. Race and ethnicity were self-reported and combined into one variable to facilitate analysis. We also collected data on other known risk factors for laceration to adjust our analysis accordingly. RESULTS A total of 1179 charts met criteria. When comparing none, first-, or second-degree lacerations versus third or fourth degrees (obstetric anal sphincter injuries) race was not a significant factor. We also compared lacerations among the following three groups: none or first degree versus second degree versus obstetric anal sphincter injuries. In this case, Asian and white women were associated with an increasing trend of perineal lacerations as degree of severity increased (P < 0.0001), whereas black and Latina women were associated with a decreasing trend as severity increased (P < 0.0001). After adjusting for other significant variables, race was still significant (P = 0.02). CONCLUSIONS With an urban diverse population, our study demonstrates an association between race/ethnicity and perineal lacerations. As degree of laceration increased, Asian and white women were noted to have more lacerations, and black and Latina women were noted to have fewer. Because perineal lacerations pose a significant risk to future pelvic floor health, the associated factors identified in this study may prove useful in counseling patients on future risk or in identifying the actual risk in underrepresented populations.

Abstract
BACKGROUND Vacuum and forceps assisted vaginal deliveries are reported to increase the incidence of postpartum infections and maternal readmission to hospital compared to spontaneous vaginal delivery. Prophylactic antibiotics may be prescribed to prevent these infections. However, the benefit of antibiotic prophylaxis for operative vaginal deliveries is still unclear. OBJECTIVES To assess the effectiveness and safety of antibiotic prophylaxis in reducing infectious puerperal morbidities in women undergoing operative vaginal deliveries including vacuum or forceps deliveries, or both. SEARCH METHODS We searched Cochrane Pregnancy and Childbirth's Trials Register (12 July 2017), ClinicalTrials.gov, the WHO International Clinical Trials Registry Platform (ICTRP) (12 July 2017) and reference lists of retrieved studies. SELECTION CRITERIA All randomised trials comparing any prophylactic antibiotic regimens with placebo or no treatment in women undergoing vacuum or forceps deliveries were eligible. Participants were all pregnant women without evidence of infections or other indications for antibiotics of any gestational age undergoing vacuum or forceps delivery for any indications. Interventions were any antibiotic prophylaxis (any dosage regimen, any route of administration or at any time during delivery or the puerperium) compared with either placebo or no treatment. DATA COLLECTION AND ANALYSIS Two review authors assessed trial eligibility and methodological quality. Two review authors extracted the data independently using prepared data extraction forms. Any discrepancies were resolved by discussion and a consensus reached through discussion with all review authors. We assessed methodological quality of the one included trial using the GRADE approach. MAIN RESULTS One trial, involving 393 women undergoing either vacuum or forceps deliveries, was included. The trial compared the antibiotic intravenous cefotetan after cord clamping compared with no treatment. This trial reported only two out of the nine outcomes specified in this review. Seven women in the group given no antibiotics had endomyometritis and none in prophylactic antibiotic group, the risk reduction was 93% (risk ratio (RR) 0.07; 95% confidence interval (CI) 0.00 to 1.21; low-quality evidence). There was no difference in the length of hospital stay between the two groups (mean difference (MD) 0.09 days; 95% CI -0.23 to 0.41; low-quality evidence). Overall, the risk of bias was judged to be unclear. The quality of the evidence using GRADE was low for both endometritis and maternal length of stay. AUTHORS' CONCLUSIONS One small trial was identified reporting only two outcomes. Evidence from this single trial suggests that antibiotic prophylaxis may lead to little or no difference in endometritis or maternal length of stay. There were no data on any other outcomes to evaluate the impact of antibiotic prophylaxis after operative vaginal delivery. Future research on antibiotic prophylaxis for operative vaginal delivery is needed to conclude whether it is useful for reducing postpartum morbidity.

Abstract
OBJECTIVE To examine rates of attempted and successful vacuum-assisted vaginal delivery by prepregnancy body mass index (BMI). METHODS We conducted a retrospective cohort study of 2,084 women with singleton gestations needing operative delivery assistance and vacuum-eligible (fully dilated, +2 station or greater, 34 weeks of gestation or greater) using 2006-2014 inpatient records. Prepregnancy BMI was categorized as underweight (less than 18.5), normal weight (18.5 to less than 25), overweight (25 to less than 30), or obese (30 or greater). Logistic regression models estimated odds ratios (ORs) and 95% confidence intervals (CIs) of attempted and successful vacuum-assisted vaginal delivery by prepregnancy BMI adjusted for age, race, marital status, parity, diabetes, labor induction-augmentation, episiotomy, gestational age, and neonatal birth weight. RESULTS Thirty-nine percent of women requiring delivery assistance and eligible for a vacuum were overweight or obese, 79% had vacuum attempts, and 95.3% of attempted vacuum-assisted vaginal deliveries were successful. Compared with women who were normal weight prepregnancy (82.8%), women who were overweight or obese were less likely to have vacuum attempted (75.8%, OR 0.71, 95% CI 0.53-0.96 and 71.2%, OR 0.53, 95% CI 0.39-0.74, respectively). Among women with attempted vacuum-assisted vaginal delivery, successful delivery did not differ by prepregnancy BMI (92.6%, OR 0.54, 95% CI 0.21-1.37 for underweight; 94.5%, OR 1.07, 95% CI 0.57-2.00 for overweight; 96.3%, OR 1.09, 95% CI 0.51-2.33 for obese compared with 95.6% among normal-weight women). CONCLUSION Among women in need of operative delivery assistance, prepregnancy obesity was associated with lower likelihood of attempted vacuum-assisted vaginal delivery but, if attempted, success rates were similar to rates among normal-weight women. With significant morbidity of second-stage cesarean delivery in obese women, research should examine whether vacuum-assisted vaginal delivery may be appropriate for additional obese patients.

Abstract
INTRODUCTION To choose the best mode of delivery (vaginal versus caesarean section) still remains a contentious issue. Caesarean section is a major abdominal surgery with its related medical, anesthetic and surgical complications. Maternal mortality and morbidity is higher in caesarean section compared with vaginal delivery. The most common causes of maternal mortality during caesarean section are due to anesthesia, bleeding and infection. AIM The aim of this study was to determine the mode of delivery and maternal outcomes in Sanandaj's hospital, Iran, during one year. MATERIALS AND METHODS The study population included all women who were admitted for delivery in Sanandaj's Hospital. Data collection instrument was a researcher made questionnaire. Data were entered into SPSS version 20.0 and analyzed using Chi-square test. Desired outcomes were entered into multiple logistic regression models. For estimating the parameters and increasing the level of significance we used bootstrap to generate 1000 samples. RESULTS During the study, a total of 5984 deliveries were conducted in Sanandaj Hospital, of which 3423 (57.20%) were vaginal (vaginal, vaginal + episiotomy, instrumental delivery) and 2561 (42.80%) were caesarean section. The results showed a statistically significant association between delivery mode and demographic variables such as age, occupation and level of education; whereas, no significant association was found between place of residence and parity. CONCLUSION The finding of this study showed that caesarean section delivery rate in Sanandaj was 42.80% in 2012-2013 which is higher than caesarean section rate recommended by WHO. Also, there was a relationship between mode of delivery and maternal outcomes.

Abstract
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.

Abstract
BACKGROUND Maternal ethnicity is a recognized risk factor for stillbirth, such that South Asian women have higher rates than their Caucasian counterparts. However, whether maternal ethnicity is a risk factor for intrapartum outcomes is less clear. The aim of this study is to explore associations between maternal country of birth, operative vaginal delivery and emergency cesarean section, and to identify possible mechanisms underlying any such associations. METHODS We performed a retrospective cohort study of singleton term births among South Asian, South East/East Asian and Australian/New Zealand born women at an Australian tertiary hospital in 2009-2013. The association between maternal country of birth, operative vaginal birth and emergency cesarean was assessed using multivariate logistic regression. RESULTS Of the 31,932 births, 54% (17,149) were to Australian/New Zealand-born women, 25% (7874) to South Asian, and 22% (6879) to South East/East Asian born women. Compared to Australian/New Zealand women, South Asian and South East/East Asian women had an increased rate of both operative vaginal birth (OR 1.43 [1.30-1.57] and 1.22 [1.11-1.35] respectively, p < 0.001 for both) and emergency cesarean section (OR 1.67 [1.53-1.82] and 1.16 [1.04-1.26] respectively, p < 0.001 and p = 0.007 respectively). While prolonged labor was the predominant reason for cesarean section among Australian/New Zealand and South East/East Asian women, fetal compromise accounted for the majority of operative births in South Asian women. CONCLUSION South Asian and South East/East Asian women experience higher rates of both operative vaginal birth and cesarean section in comparison to Australian/New Zealand women, independent of other risk factors for intrapartum interventions.

Abstract
BACKGROUND Eastern African immigrants from countries affected by female genital mutilation have resettled in many developed countries, including Australia. Although possibly at risk of perineal trauma and episiotomy, research investigating their perineal status post-migration is sparse. AIM To investigate variations in episiotomy use and incidence of severe perineal tear for women born in Eritrea, Ethiopia, Somalia and Sudan compared with Australian-born women. METHODS A population-based study of 203,206 Australian-born and 3502 Eastern African immigrant women admitted as public patients, with singleton vaginal births between 1999 and 2007, was conducted using the Victorian Perinatal Data Collection. Descriptive and multivariable logistic regression analysis adjusting for confounders selected a priori, were performed to compute incidence and adjusted odds ratios. FINDINGS Overall, 30.5% Eastern African immigrants had episiotomy compared to 17.2% Australian-born women. Severe perineal trauma occurred in 2.1% of Eastern African immigrants and 1.6% of Australian-born women. While the odds of severe perineal trauma was significantly elevated only during non-instrumental vaginal births for Eastern African immigrants {ORadj1.56 95%CI(1.17, 2.12)}; that of episiotomy was increased during both non-instrumental {ORadj4.47 95%CI(4.10, 4.88)} and instrumental {ORadj2.51 95%CI(1.91, 3.29)} vaginal births. CONCLUSIONS Overall, Eastern African immigrant women experienced elevated odds of episiotomy and severe perineal tear. Health care providers need to be mindful of the increased risk of severe perineal tear in these women and enhance efforts in identification and treatment of severe perineal trauma to minimise associated short and long term morbidity. Strategies to reduce unneeded episiotomy and ways of enhancing perineal safety are also needed.

Obstetric anal sphincter injuries after episiotomy: systematic review and meta-analysis. Int Urogynecol J 2016; 27:1459-67.

Abstract
Introduction There is conflicting evidence on whether mediolateral episiotomy (MLE) reduces the risk of obstetric anal sphincter injuries (OASI) in spontaneous vaginal deliveries (SVD). Objectives A systematic review was undertaken to compare rates of OASI amongst women who had undergone mediolateral episiotomy versus those who did not. Methods ᅟ Search strategy Electronic searches were performed in literature databases: CINAHL, Cochrane, EMBASE, Medline and MIDIRS from database inception to July 2015. Studies were eligible if MLE was compared to spontaneous tears and if OASI was the outcome of interest. Two reviewers independently selected and extracted data on study characteristics, quality and results. We computed events of OASI in those who did and did not have an episiotomy from individual studies and pooled these results in a meta-analysis where possible. Main results Of the 2090 citations, 16 were included in the review. All were non-randomised, population based or retrospective cohort studies. There was great variation in quality amongst these studies. Data from 7 studies was used for meta-analysis. On collating data from these studies where the majority of women (636755/651114) were nulliparous, MLE reduced the risk of OASI (RR 0.67 95 % CI 0.49-0.92) in vaginal delivery. Conclusion The pooled analysis of a large number of women undergoing vaginal birth, most of who were nulliparous, indicates that MLE has a beneficial effect in prevention of OASI. An accurately given MLE might have a role in reducing OASI and should not be withheld, especially in nulliparous women. Caution is advised as the data is from non-randomised studies.

Perineal body stretch during labor does not predict perineal laceration, postpartum incontinence, or postpartum sexual function: a cohort study. Int Urogynecol J 2016; 27:1193-200.

Abstract
INTRODUCTION AND HYPOTHESIS The perineum stretches naturally during obstetrical labor, but it is unknown whether this stretch has a negative impact on pelvic floor outcomes after a vaginal birth (VB). We aimed to evaluate whether perineal stretch was associated with postpartum pelvic floor dysfunction, and we hypothesized that greater perineal stretch would correlate with worsened outcomes. METHODS This was a prospective cohort study of primiparous women who had a VB. Perineal body (PB) length was measured antepartum, during labor, and 6 months postpartum. We determined the maximum PB (PBmax) measurements during the second stage of labor and PB change (ΔPB) between time points. Women completed functional questionnaires and had a Pelvic Organ Prolapse Quantification (POP-Q) system exam 6 months postpartum. We analyzed the relationship of PB measurements to perineal lacerations and postpartum outcomes, including urinary, anal, and fecal incontinence, sexual activity and function, and POP-Q measurements. RESULTS Four hundred and forty-eight women with VB and a mean age of 24 ± 5.0 years with rare (5 %) third- or fourth-degree lacerations were assessed. During the second stage of labor, 270/448 (60 %) had perineal measurements. Mean antepartum PB length was 3.7 ± 0.8 cm, with a maximum mean PB length (PBmax) during the second stage of 6.1 ± 1.5 cm, an increase of 65 %. The change in PB length (ΔPB) from antepartum to 6 months postpartum was a net decrease (-0.39 ± 1.02 cm). PB change and PBmax were not associated with perineal lacerations or outcomes postpartum (all p > 0.05). CONCLUSIONS PB stretch during labor is unrelated to perineal laceration, postpartum incontinence, sexual activity, or sexual function.

Abstract
IMPORTANCE Shoulder dystocia is an obstetric emergency with potential catastrophic outcomes. OBJECTIVE To perform a systematic literature review examining the effectiveness of episiotomy in the prevention and management of shoulder dystocia during vaginal birth. EVIDENCE ACQUISITION Search was conducted by a research librarian in MEDLINE, Web of Science, Cochrane Library, and SCOPUS databases using the terms "episiotomy" and "shoulder dystocia," with no language or time restrictions. Two investigators independently selected original researches examining the effects of episiotomy on shoulder dystocia and its neonatal andmaternal outcomes. Relevant articles were accessed in full text, including manual search of the references. We contacted authors of studies with insufficient or unclear data. Because of clinical and methodological diversity of the studies, meta-analysis was not performed. RESULTS Fourteen articles met the inclusion criteria, encompassing a total of 9769 shoulder dystocia cases. Only 1 study effectively evaluated the role of episiotomy in shoulder dystocia prevention, yielding a nonsignificant result. Three articles assessed neonatal consequences of shoulder dystocia, one of them linking episiotomy to higher risk of neonatal injury. Two of the 3 studies evaluating maternal outcomes showed that episiotomy is related to increased risk of advanced perineal tears. Overall quality of evidence was rated as very low. CONCLUSIONS AND RELEVANCE Our systematic review found no evidence supporting the use of episiotomy in the prevention and management of shoulder dystocia. This observation carries major clinical and legal implications for the obstetricians. Higher-quality studies are needed to evaluate this important issue.

Abstract
Objective. To determine if there is an association between BMI and 3rd- or 4th-degree perineal lacerations in normal spontaneous and operative vaginal deliveries. Study Design. We performed a retrospective case control study using a large obstetric quality improvement database over a six-year period. Cases were identified as singleton gestations with third- and fourth-degree lacerations. Controls were obtained randomly from the database of patients without third- or fourth-degree lacerations in a 1 : 1 ratio. Univariate and multivariate logistic regression analyses were performed. Results. Of 32,607 deliveries, 22,011 (67.5%) charts with BMI documented were identified. Third- or fourth-degree lacerations occurred in 2.74% (n = 605) of patients. 37% (n = 223) were identified in operative vaginal deliveries. In the univariate analysis, obesity, older maternal age, non-Asian race, and birth weight <4000 g were all protective against 3rd- and 4th-degree lacerations. After controlling for age, race, mode of vaginal delivery, and birth weight, obesity remained significant. Conclusion. Being obese may protect against third- and fourth-degree lacerations independent of parity, race, birth weight, and mode of delivery.

Abstract
INTRODUCTION Obstetric trauma leading to rectovaginal fistula (RVF) formation results from perineal laceration and/or from prolonged ischemia and necrosis following obstructed labor. Due to modern obstetric care fistulas are rare in industrialized countries. METHODS Patients undergoing surgery for a RVF between January 2005 and December 2014 at the Department of Obstetrics and Gynecology, Tuebingen, Germany, were identified and their records were reviewed retrospectively. RESULTS Of 48 patients, 13 developed RVF of obstetric etiology. Parity ranged from 2 to 4. RVF repair was performed in all patients using a transvaginal approach: fistula excision and multilayer closure (7 of 13) with Martius flap interposition (1 of 7) and sphincteroplasty (5 of 13). One RVF closed spontaneously. Due to significant destruction of the anal canal, large RVF and RVF recurrence, 4 of the 13 patients needed a temporary protective ileostomy. Fistula closure was achieved in 12 of 13 patients. CONCLUSION The choice of RVF repair should be tailored to the underlying pathology and type of repair done previously and the patient's wishes.

Abstract
INTRODUCTION AND HYPOTHESIS Obstetric anal sphincter injuries (OASIs) are the leading cause of anal incontinence in women. Modification of various risk factors and anatomical considerations have been reported to reduce the rate of OASI. METHODS A PubMed search (1989-2014) of studies and systematic reviews on risk factors for OASI. RESULTS Perineal distension (stretching) of 170 % in the transverse direction and 40 % in the vertical direction occurs at crowning, leading to significant differences (15-30°) between episiotomy incision angles and suture angles. Episiotomies incised at 60° achieve suture angles of 43-50°; those incised at 40° result in a suture angle of 22°. Episiotomies with suture angles too acute (<30°) and too lateral (>60°) are associated with an increased risk of OASI. Suture angles of 40-60° are in the safe zone. Clinicians are poor at correctly estimating episiotomy angles on paper and in patients. Sutured episiotomies originating 10 mm away from the midline are associated with a lower rate of OASIs. Compared to spontaneous tears, episiotomies appear to be associated with a reduction in OASI risk by 40-50 %, whereas shorter perineal lengths, perineal oedema and instrumental deliveries are associated with a higher risk. Instrumental deliveries with mediolateral episiotomies are associated with a significantly lower OASI risk. Other preventative measures include warm perineal compresses and controlled delivery of the head. CONCLUSIONS Relieving pressure on the central posterior perineum by an episiotomy and/or controlled delivery of the head should be important considerations in reducing the risk of OASI. Episiotomies should be performed 60° from the midline. Prospective studies should evaluate elective episiotomies in women with a short perineal length and application of standardised digital perineal support.

Abstract
Research on obstetric fistula has paid limited attention to the lived experiences of survivors. This qualitative study explored the evolution of survivors' perceptions of their social relationships and health since developing this obstetric complication. In-depth interviews were conducted with eight survivors who were selected based on purposive and snowball sampling techniques. Thematic categorization and content analysis was used to analyze the data. The resultant themes included participants' understanding of factors predisposing to fistula, challenges they encounter, their coping responses, and the meaning of their experiences. First, the participants had a common understanding of the factors that predisposed them to obstetric fistula. They mentioned poor knowledge about pregnancy, early marriage, cultural practices, and a delay in or lack of access to emergency obstetric care. Second, the participants suffered from powerlessness experienced during their childhood and married lives. They also faced prolonged obstructed labor, physical injury, emotional breakdown, depression, erosion of social capital, and loss of healthy years. Third, to control their negative emotions, participants reported isolating themselves, having suicidal thoughts, positive interpretation about the future, and avoidance. To obtain relief from their disease, the women used their family support, sold their properties, and oriented to reality. Fourth, the participants were struggling to keep going, to accept their changed reality, and to change their perspectives on life. In conclusion, obstetric fistula has significant physical, psychosocial, and emotional consequences. The study participants were not passive victims but rather active survivors of these challenges. Adequate support was not provided by their formal or informal support systems. To prevent and manage obstetric fistula successfully, there should be family-based interventions that improve access to and provision of emergency obstetric care. These initiatives should also ensure men's participation, women's empowerment, and the utilization of community-based institutions.

Abstract
BACKGROUND Vacuum and forceps assisted vaginal deliveries are reported to increase the incidence of postpartum infections and maternal readmission to hospital compared to spontaneous vaginal delivery. Prophylactic antibiotics may be prescribed to prevent these infections. However, the benefit of antibiotic prophylaxis for operative vaginal deliveries is still unclear. OBJECTIVES To assess the effectiveness and safety of antibiotic prophylaxis in reducing infectious puerperal morbidities in women undergoing operative vaginal deliveries including vacuum or forceps deliveries, or both. SEARCH METHODS We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (31 August 2014). SELECTION CRITERIA All randomised trials comparing any prophylactic antibiotic regimens with placebo or no treatment in women undergoing vacuum or forceps deliveries were eligible. Participants were all pregnant women without evidence of infections or other indications for antibiotics of any gestational age undergoing vacuum or forceps delivery for any indications. Interventions were any antibiotic prophylaxis (any dosage regimen, any route of administration or at any time during delivery or the puerperium) compared with either placebo or no treatment. DATA COLLECTION AND ANALYSIS Two review authors assessed trial eligibility and methodological quality. Two review authors extracted the data independently using prepared data extraction forms. Any discrepancies were resolved by discussion and a consensus reached through discussion with all review authors. For this update, we assessed methodological quality of the one included trial using the standard Cochrane criteria and the GRADE approach. We calculated the risk ratio (RR) and mean difference (MD) using a fixed-effect model and all the review authors interpreted and discussed the results. MAIN RESULTS One trial, involving 393 women undergoing either vacuum or forceps deliveries, was included. This trial identified only two out of the nine outcomes specified in this review. It reported seven women with endomyometritis in the group given no antibiotic and none in prophylactic antibiotic group. This difference did not reach statistical significance, but the risk reduction was 93% (risk ratio (RR) 0.07; 95% confidence interval (CI) 0.00 to 1.21). There was no difference in the length of hospital stay between the two groups (mean difference (MD) 0.09 days; 95% CI -0.23 to 0.41). Overall, the risk of bias was judged as low. The quality of the evidence using GRADE was low for both endometritis and maternal length of stay. AUTHORS' CONCLUSIONS The data were too few to make any recommendations for practice. Future research on antibiotic prophylaxis for operative vaginal delivery is needed to conclude whether it is useful for reducing postpartum morbidity.

Abstract
OBJECTIVE The objective of this study was to evaluate the protective effects of a new device for reducing perineal tears during vaginal childbirth. STUDY DESIGN A multicenter open randomized controlled trial (RCT) was performed in Helsingborg, Lund and Malmö, Sweden consisting of 1148 women. Women anticipating a vaginal delivery were either randomized to the intervention group (n=574 in which the perineal protection device was used, or a control group (n=574), in which the perineal protection device was not used. The main outcome measurements were incidence of vaginal and perineal tears (1st to 4th degree tears) and adverse effects on the parturient and newborn. RESULTS The incidences of first- and second-degree tears of the vagina (p=0.018) and perineum (p=0.005) were significantly reduced in the intervention group compared with the controls. In the intervention- and control group, 184 women (34.9%) and 142 (26.6%) showed no perineal tearing, respectively (p=0.034). Numbers needed to treat to avoid any perianal tearing was 12. The incidence of anal sphincter rupture (ASR) was the same in both groups (n=19; 3.4%). No negative effects on mother or child from using the device were observed. CONCLUSIONS The perineal protective device significantly reduced the incidence of first- and second-degree tears in the vagina and perineum during vaginal birth and also significantly increased the number of parturients with a fully intact posterior commissure. No significant reduction of ASR and no negative effects of the device were observed.

BMC Pregnancy Childbirth 2014; 14:156. [PMID: 24885981 PMCID: PMC4012520 DOI: 10.1186/1471-2393-14-156] [Citation(s) in RCA: 18] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/26/2013] [Accepted: 04/26/2014] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND The number of infants with a birth weight > 97th percentile for gestational age has increased over the years. Although some studies have examined the interest of inducing labor for fetuses with macrosomia suspected in utero, only a few have analyzed this suspected macrosomia according to estimated weight at each gestational age. Most studies have focused principally on neonatal rather than on maternal (and still less on perineal) outcomes. The principal aim of this study was to assess whether a policy of induction of labor for women with a constitutionally large-for-gestational-age fetus might reduce the occurrence of severe perineal tears; the secondary aims of this work were to assess whether this policy would reduce either recourse to cesarean delivery during labor or neonatal complications. METHODS This historical cohort study (n = 3077) analyzed records from a French perinatal database. Women without diabetes and with a cephalic singleton term pregnancy were eligible for the study. We excluded medically indicated terminations of pregnancy and in utero fetal deaths. Among the pregnancies with fetuses suspected, before birth, of being large-for-gestational-age, we compared those for whom labor was induced from ≥ 37 weeks to ≤ 38 weeks+ 6 days (n = 199) to those with expectant obstetrical management (n = 2878). In this intention-to-treat analysis, results were expressed as crude and adjusted relative risks. RESULTS The mean birth weight was 4012 g ± 421 g. The rate of perineal lesions did not differ between the two groups in either primiparas (aRR: 1.06; 95% CI: 0.86-1.31) or multiparas (aRR: 0.94; 95% CI: 0.84-1.05). Similarly, neither the cesarean rate (aRR: 1.11; 95% CI: 0.82-1.50) nor the risks of resuscitation in the delivery room or of death in the delivery room or in the immediate postpartum or of neonatal transfer to the NICU (aRR = 0.94; 95% CI: 0.59-1.50) differed between the two groups. CONCLUSIONS A policy of induction of labor for women with a constitutionally large-for-gestational-age fetus among women without diabetes does not reduce maternal morbidity.

Abstract
OBJECTIVE To determine modifiable risk factors and incidence of obstetric anal sphincter injury (OASIS) in primiparous women. STUDY DESIGN We performed a population-based retrospective cohort study, using data from the Danish Medical Birth Registry. The population consisted of primiparous women with a vaginal delivery in the time period 2000-2010. Univariable and multivariable logistic regressions were used to determine risk factors of OASIS. Main outcome measures were incidence of OASIS in first vaginal delivery, odds ratios for possible risk factors: age, body mass index, birthweight, head circumference, gestational age, presentation, induction of labor, oxytocin augmentation, epidural, mediolateral episiotomy, vacuum extraction, forceps, shoulder dystocia, and year of delivery. RESULTS Of 214,256 primiparous women with a vaginal delivery, 13,907 (6.5%; 95% confidence interval [CI] 6.4-6.6%) experienced an OASIS. The incidence of OASIS increased in the time period (adjusted odds ratio [aOR], 1.02; 95% CI, 1.02-1.03; P < .0001, per year). We found a protective effect of epidural analgesia (aOR, 0.84; 95% CI, 0.81-0.88; P = .0001). Vacuum extraction without episiotomy was a significant risk factor of OASIS (aOR, 2.99; 95% CI, 2.86-3.12; P < .0001), and episiotomy was protective in vacuum-assisted deliveries compared with vacuum-assisted deliveries without episiotomy (aOR, 0.60; 95% CI, 0.56-0.65; P < .0001). Birthweight was found to be an important nonmodifiable risk factor (aOR, 2.76; 95% CI, 2.62-2.90; P < .0001). CONCLUSION Epidural analgesia in itself was protective against OASIS. Vacuum extraction increased the risk of OASIS, although mediolateral episiotomy was protective when applied in deliveries assisted by vacuum extraction.

Abstract
OBJECTIVE To assess the rate of antibiotic administration following vaginal delivery and to determine whether maternal characteristics and healthcare system features affected antibiotic use during or immediately after delivery using data from the WHO Global Survey on Maternal and Perinatal Health in Latin America, Africa, and Asia. METHODS The study included women who delivered vaginally without any obvious infection, diabetes, HIV, cardiorenal or respiratory disease, urinary tract infection, or rupture of membranes. The proportion of women receiving antibiotics within and across regions was determined and associated factors of prophylactic use were analyzed using generalized linear mixed models. RESULTS Of the 171,676 women giving birth vaginally, 47.3% received antibiotics, with half of these women receiving antibiotics during and/or immediately after delivery for prophylaxis. Among 131,554 women given prophylactic or no antibiotics, 31.2% received prophylactic antibiotics but the rate varied among regions. Women with an operative vaginal delivery (compared with those who delivered spontaneously) and women with third- or fourth-degree laceration were more likely to receive prophylactic antibiotics. CONCLUSION Antibiotic use following vaginal delivery varies widely across geographic regions; however, approximately one-third of women undergoing vaginal delivery without documented indication for antibiotic administration appear to have received antibiotics.

Abstract
Postpartum depression (PPD) is a relatively common and often severe mood disorder that develops in women after childbirth. The aetiology of PPD is unclear, although there is emerging evidence to suggest a psychoneuroimmune connection. Additionally, deficiencies in n-3 PUFA, B vitamins, vitamin D and trace minerals have been implicated. This paper reviews evidence for a link between micronutrient status and PPD, analysing the potential contribution of each micronutrient to psychoneuroimmunological mechanisms of PPD. Articles related to PPD and women's levels of n-3 PUFA, B vitamins, vitamin D and the trace minerals Zn and Se were reviewed. Findings suggest that while n-3 PUFA levels have been shown to vary inversely with PPD and link with psychoneuroimmunology, there is mixed evidence regarding the ability of n-3 PUFA to prevent or treat PPD. B vitamin status is not clearly linked to PPD, even though it seems to vary inversely with depression in non-perinatal populations and may have an impact on immunity. Vitamin D and the trace minerals Zn and Se are linked to PPD and psychoneuroimmunology by intriguing, but small, studies. Overall, evidence suggests that certain micronutrient deficiencies contribute to the development of PPD, possibly through psychoneuroimmunological mechanisms. Developing a better understanding of these mechanisms is important for guiding future research, clinical practice and health education regarding PPD.

Abstract
OBJECTIVE The purpose of this study was to compare the risk of surgically treated stress urinary incontinence (SUI) and pelvic organ prolapse (POP) in relation to mode of delivery and age at first childbirth. STUDY DESIGN This was a cohort study. Data from the Swedish Medical Birth Register on women with only cesarean delivery (n = 30,880 women) or only vaginal delivery (n = 59,585 women) were compared with the Swedish Patient Register to calculate incidence rates and hazard ratios (95% confidence interval [CI]) for SUI and POP surgery. RESULTS In analyses that were stratified by age, vaginal delivery consistently increased the risks of SUI and POP surgery. Among vaginally delivered women who were ≥ 30 years old, incidence rates of POP surgery were 13.8 (95% CI, 12.7-15.1), and for younger women were 6.4 (95% CI, 6.0-6.8) per 10,000 person-years. Exclusion of instrumental vaginal delivery did not alter the conclusions. CONCLUSION Increasing age at first delivery increased the risk of subsequent SUI and POP surgery after both vaginal and cesarean delivery.
