Introdução: A laceração obstétrica do esfíncter anal (LOEA) está associado com incontinência anal. A episiotomia foi proposta como uma forma de proteção do esfíncter anal no parto, especialmente a episiotomia mediolateral; entretanto, diversos estudos mostraram que o uso de rotina da episiotomia não reduz o risco de LOEA. Objetivo: Este estudo tem por objetivo analisar se a redução na taxa de episiotomia em hospital escola no Brasil foi associada a um aumento na incidência de lacerações obstétricas do esfíncter anal, além de fatores associados a elas. Métodos: Estudo observacional, transversal e retrospectivo, realizado no Hospital de Clínicas de Porto Alegre, Rio Grande do Sul, Brasil. Foram incluídos todos os partos vaginais de gestações únicas, apresentação cefálica, a partir de 34 semanas de idade gestacional, realizados em 2011-2012 (uso liberal da episiotomia) e 2015-2016 (uso restrito da episiotomia), e comparados em relação a taxa de episiotomia mediolateral e de LOEA. Resultados: foram analisados 4268 partos (2043 no período de 2011-2012, 2225 de 2015-2016), foram analisados 2043 partos. A taxa de episiotomia reduziu de 59.4% para 44.2% (p≤0.0001). No período 2011-2012, ocorreram 10 lacerações obstétricas do esfíncter anal em 2043 partos (0.48%), enquanto que no período 2015-2016, ocorreram 31 lacerações em 2225 partos (1.39%). Houve interação quando comparado os dois períodos em relação a realização de episiotomia e a ocorrência de LOEA (p≤0.0001). A episiotomia foi fortemente associada a não ocorrência de LOEA em 2011-2012 (59.5%), enquanto que não ter episiotomia foi associado ao grupo com (67.7%) e sem LOEA (55.7%) em 2015-2016. Fatores associados a LOEA foram indução do parto e distócia de ombro. Conclusão: Houve um aumento na taxa de lacerações do esfíncter anal com a diminuição da taxa de episiotomia.

Episiotomy was proposed as a form of protection of the anal sphincter at delivery, especially mediolateral episiotomy; however, several studies have shown that routine use of episiotomy does not reduce the risk of OAST. Objective: This study aims to analyse whether the reduction in the rate of episiotomy in a school hospital in Brazil was associated with an increase in the incidence of obstetric lacerations of the anal sphincter, in addition to associated factors. Methods: Observational, cross-sectional and retrospective study, conducted at Hospital de Clínicas, Porto Alegre, Rio Grande do Sul, Brazil. We included all vaginal deliveries of single pregnancies, cephalic presentation, from 34 weeks of gestational age, performed in 2011-2012 (liberal episiotomy) and 2015- 2016 (restricted episiotomy), and compared in relation to the rate of mediolateral episiotomy and OAST. Results: 4268 births were analysed (2043 in 2011-2012 and 2225 in 2015-2016). The episiotomy rate decreased from 59.4% to 44.2% (p≤0.0001). In 2011-2012, there were 10 obstetric anal sphincter lacerations in 2043 births (0.48%), while in the period 2015-2016 there were 31 lacerations in 2225 births (1.39%). There was interaction when comparing the two periods in relation to the episiotomy and the occurrence of OAST (p≤0.0001). Episiotomy was strongly related to 2011-2012 group with no OAST (59.5%), while not having an episiotomy was related to both OAST (67.7%) and no OAST (55.7%) group in 2015-2016. Factors associated with OAST were labor induction and shoulder dystocia. Conclusion: There was an increase in the rate of lacerations of the anal sphincter with a decrease in the rate of episiotomy. Routine episiotomy was protective.

Osteopathic Manipulative Treatment (OMT) has been used for more than 100 years to enhance the physiologic process of labor and delivery by normalizing pelvic structures and providing adequate blood supply to the uterus. Since maternal morbidity and mortality is a major health concern for developing countries, it was desirable to explore the benefits of OMT. After IRB approval by the Virginia College of Osteopathic Medicine and Virginia Tech, the research was conducted in Santo Domingo, Dominican Republic at Hospital Maternidad Nuestra Señora de la Altagracia to determine the relationship of OMT during labor and delivery on rates of cesarean section and perineal lacerations/ episiotomies. Qualifying candidates received the next sequentially numbered envelope with a randomized number assigning her to either the treatment or control group. Staff physicians at the hospital provided care to women in the control group according to their standard protocol. Four Osteopathic Physicians and one pre-doctoral OMM fellow performed OMT on women during the first and second stages of labor and performed their deliveries. There were 33 parturients in the OMT Treatment group and 32 in the control, for a total of 65 in the trial. The results of a logistic regression analysis using Wald criterion, with a statistical significance of alpha = 0.05, indicated treatment group reduction of rates of episiotomies in the primiparous (P = .04) and marginal significance in the combined primiparous and multiparous population (P = .05). The percentage of episiotomies in the primiparous treatment group was 35.29% and 75% in the control group. The percentage of episiotomies in the combined primiparous and multiparous groups were 15.15% in the treatment group and 37.5% in the control group. The cesarean rate for the treatment group was 9.09% and 18.75% for the control group (P = 0.098). The percentages of grade I & II perineal lacerations were 15.15% for the treatment group and 12.5% for the control group (P = 0.55) due to the extensive use of episiotomies in the control group. There were composite calculations made of the total number of parturients who had either a cesarean section, an episiotomy, or a perineal laceration so that overall maternal morbidity in each group could be compared. In the combined groups, there were fourteen total parturients (42.42%) who had undergone one of the three outcomes measures in the treatment group and twenty-one (65.63%) in the control group. This brings an odds ratio of 0.200 and a significant P value of 0.0235. Though cross-cultural issues made it difficult to perform the research as originally intended, there is evidence that Osteopathic Obstetrics provides benefit to parturients. A multi-institutional randomized controlled trial is proposed as the next step for the evaluation of OMT during labor and delivery. / Ph. D.

Background: Sphincter injury is serious complication in connection to vaginal childbirth. Desire to avoid vaginal birth again is seen in women who previously suffered from a sphincter injury. Objective: To identify and evaluate obstetric guidelines in Sweden regarding sphincter injury in relation to childbirth Method: Content analysis with a combination of a deductive and inductive approach. Results: The most frequently occurring risk factors and prevention with help of perineal protection were described in the guidelines. The physician made diagnosis and repaired the sphincter injury at the theatre.  Complications such as coital pain and anal incontinence were described in the guidelines. Paracetamol and diclofenac was most common analgesic regimen given for pain. Prophylaxis such as antibiotic treatment and laxative were common. Information given to women was described. Follow-up by physician, midwife and physiotherapist was recommended after four weeks to six months. For future birth a cesarean section was recommended. Conclusion: The guidelines were constructed in the same way and had to a large extent similar content. The authors of the present work recommend a national guideline. / Bakgrund: Sfinkterskada är en allvarlig komplikation i samband med vaginal förlossning. Önskan om att undvika vaginal förlossning igen ses hos kvinnor som tidigare drabbats av sfinkterskada. Syfte: Syftet med studien var att ta reda på om det fanns riktlinjer gällande sfinkterskada i samband med förlossning vid Sveriges förlossningskliniker samt sammanställa och granska innehållet i riktlinjerna. Metod: Innehållsanalys med en kombination av deduktiv och induktiv ansats. Resultat: Av de 39 kliniker som svarade hade 31 riktlinjer gällande sfinkterskada. I riktlinjerna beskrevs vanligast förekommande riskfaktorer samt prevention med hjälp av perinealskydd. Läkaren ställde diagnos och utförde reparation av sfinkterskadan på operationsavdelningen. Komplikationer som samlagssmärta och anal inkontinens fanns beskrivet i riktlinjerna. Paracetamol och diklofenak var den vanligast förekommande smärtlindringen. Profylax som antibiotikabehandling och laxantia gavs av de flesta förlossningskliniker. Information till den nyförlösta kvinnan beskrevs. Uppföljning hos läkare, barnmorska och sjukgymnast rekommenderades efter fyra veckor till sex månader. Vid kommande graviditet och förlossning föredrogs kejsarsnitt. Slutsats: Riktlinjerna var uppbyggda på samma sätt och hade till stor del liknande innehåll. Författarna till föreliggande fördjupningsarbete efterfrågar en nationell riktlinje.
