OBJECTIVE To evaluate the association between median episiotomy and severe (third- and fourth-degree) perineal lacerations in primiparous women. DESIGN Retrospective cohort study. SETTING University-affiliated hospital providing secondary obstetric care in Quebec City. PATIENTS A total of 6522 primiparous women who gave birth vaginally to a single live baby in cephalic position between 19...

BACKGROUND We sought to investigate the impact of the duration of second stage of labor on risk of severe perineal lacerations (third and fourth degree). METHODS This population based cohort study was conducted in the Stockholm/Gotland region, Sweden, 2008-2014. Study population included 52 211 primiparous women undergoing vaginal delivery with cephalic presentation at term. Unconditional log...

BACKGROUND To compare the postpartum pelvic floor function of women with sutured second-degree perineal lacerations, unsutured second-degree perineal lacerations, and intact perineums. METHODS A prospective cohort of nurse-midwifery patients consented to mapping of genital trauma at birth and an assessment of postpartum pelvic floor outcomes. Women completed validated questionnaires for perin...

External fixation combined with colostomy is a traditional management of the pelvic fractures associated with perineal lacerations. However, malunion and dysfunction caused by malreduction and loss of reduction are common. One-stage definitive fixation without soft tissue harassment is requisite for the treatment. The purpose of this study was to assess the outcome of 1-stage definitive fixatio...

BACKGROUND This study assessed whether epidural analgesia was an independent risk factor for severe perineal laceration. METHODS A retrospective cohort study analyzed 2,759 patients at St. Francis Regional Medical Center who had vertex, spontaneous or induced, singleton, live, vaginal deliveries of neonates of at least 36 weeks' gestation. Patients with diabetes or severe cardiac disease were...

Third-degree perineal lacerations in 7 mares were repaired surgically by a one-stage method (Goetz technique). Primary healing occurred in all of them without any complication. The conception rate obtained after surgery was 70.1%. Five horses out of seven got pregnant after surgery and no further injury was seen at subsequent foaling. Three mares have produced several healthy foals without any ...

Lacerations are common after vaginal birth. Trauma can occur on the cervix, vagina, and vulva, including the labial, periclitoral, and periurethral regions, and the perineum. Most of these lacerations do not result in adverse functional outcomes. Severe perineal lacerations, extending into or through the anal sphincter complex, although less frequent, are more commonly associated with increased...

CONTEXT AND OBJECTIVE Despite all the medical care provided during delivery labor, perineal injury is still prevalent and may lead to diverse pelvic floor disorders. The aim here was to investigate the prevalence of obstetric and anal sphincter injuries (OASIS) in healthy pregnant women after vaginal delivery. DESIGN AND SETTING Cross-sectional study involving 3,034 patients with singletons i...
