Cesarean delivery and anal sphincter injury

摘要: Abstract Objective: Cesarean delivery has been thought to prevent all obstetric anal sphincter damage. The objective of this study was determine the relationship between timing cesarean during primiparous and injury mechanism. Methods: A prospective observational conducted, using a continence questionnaire anorectal physiology assessment before six weeks after delivery. cohort 234 women were recruited from antenatal clinics at National Maternity Hospital, Dublin. Thirty-four delivered subsequently by cesarean, 200 spontaneous vaginal Results: underwent without attempted delivery: eight prior labor 26 labor, 17 in early (cervical dilatation less than 8 cm) 9 late (dilatation greater cm). No woman had altered fecal postpartum. Anorectal unaltered elective or labor. Pudendal nerve terminal motor latency prolonged, squeeze pressure increment reduced, but vector symmetry index unchanged indicating neurologic Conclusion: performed even absence delivery, does not protect
