Unifesp- Brasil RELATION BETWEEN VAGINAL HIATUS AND PERINEAL BODY LENGTHS WITH EPISIOTOMY IN VAGINAL DELIVERY Hypothesis / aims of study The aim of the study was to assess the relationship between vaginal hiatus and perineal body lengths with the occurrence of episiotomy during vaginal delivery. Study design, materials and methods It´s a cross-sectional observational study with a consecutive sample of 60 parturients, made from July 2009 to March 2010 in the Obstetric Center at University Hospital in São Paulo, Brazil. Inclusion criteria were parturients at term (37 to 42 weeks gestation) in the first stage of labour, with less than 9 cm dilatation, with a single fetus in cephalic presentation and good vitality confirmed by cardiotocography. Exclusion criteria were parturients submitted to cesarean section or forceps delivery. The patients were evaluated in the lithotomic position. The measurement was performed in the first stage of labour, by the same examiner using a metric measuring tape previously cleaned with alcohol 70% and discarded after each use. The vaginal hiatus length (distance between the external urethral meatus and the vulvar fourchette) and the perineal body (distance between the vulvar fourchette and the center of the anal orifice) were evaluated. For statistical analysis the SPSS (Statistical Package for Social Sciences) version 17® was used, applying Mann-Whitney Test and Spearman Rank Correlation Test to determine the importance of vaginal hiatus and perineal body length in the occurrence of episiotomy, with p<0.05.

  • Gtg-No-20B-Breech-Presentation.Pdf
    Guideline No. 20b December 2006 THE MANAGEMENT OF BREECH PRESENTATION This is the third edition of the guideline originally published in 1999 and revised in 2001 under the same title. 1. Purpose and scope The aim of this guideline is to provide up-to-date information on methods of delivery for women with breech presentation. The scope is confined to decision making regarding the route of delivery and choice of various techniques used during delivery. It does not include antenatal or postnatal care. External cephalic version is the topic of a separate RCOG Green-top Guideline No. 20a: ECV and Reducing the Incidence of Breech Presentation. 2. Background The incidence of breech presentation decreases from about 20% at 28 weeks of gestation to 3–4% at term, as most babies turn spontaneously to the cephalic presentation. This appears to be an active process whereby a normally formed and active baby adopts the position of ‘best fit’ in a normal intrauterine space. Persistent breech presentation may be associated with abnormalities of the baby, the amniotic fluid volume, the placental localisation or the uterus. It may be due to an otherwise insignificant factor such as cornual placental position or it may apparently be due to chance. There is higher perinatal mortality and morbidity with breech than cephalic presentation, due principally to prematurity, congenital malformations and birth asphyxia or trauma.1,2 Caesarean section for breech presentation has been suggested as a way of reducing the associated perinatal problems2,3 and in many countries in Northern Europe and North America caesarean section has become the normal mode of breech delivery.

  • Chapter 12 Vaginal Breech Delivery
    FOURTH EDITION OF THE ALARM INTERNATIONAL PROGRAM CHAPTER 12 VAGINAL BREECH DELIVERY Learning Objectives By the end of this chapter, the participant will: 1. List the selection criteria for an anticipated vaginal breech delivery. 2. Recall the appropriate steps and techniques for vaginal breech delivery. 3. Summarize the indications for and describe the procedure of external cephalic version (ECV). Definition When the buttocks or feet of the fetus enter the maternal pelvis before the head, the presentation is termed a breech presentation. Incidence Breech presentation affects 3% to 4% of all pregnant women reaching term; the earlier the gestation the higher the percentage of breech fetuses. Types of Breech Presentations Figure 1 - Frank breech Figure 2 - Complete breech Figure 3 - Footling breech In the frank breech, the legs may be extended against the trunk and the feet lying against the face. When the feet are alongside the buttocks in front of the abdomen, this is referred to as a complete breech. In the footling breech, one or both feet or knees may be prolapsed into the maternal vagina. Significance Breech presentation is associated with an increased frequency of perinatal mortality and morbidity due to prematurity, congenital anomalies (which occur in 6% of all breech presentations), and birth trauma and/or asphyxia. Vaginal Breech Delivery Chapter 12 – Page 1 FOURTH EDITION OF THE ALARM INTERNATIONAL PROGRAM External Cephalic Version External cephalic version (ECV) is a procedure in which a fetus is turned in utero by manipulation of the maternal abdomen from a non-cephalic to cephalic presentation. Diagnosis of non-vertex presentation Performing Leopold’s manoeuvres during each third trimester prenatal visit should enable the health care provider to make diagnosis in the majority of cases.

  • Maternity Information for Childbirth Services
    Maternity information for childbirth services What you need to know 20905-3-17 New York State’s Maternity Information Law requires each hospital to provide the following information about its childbirth practices and procedures. This information will help you to better understand what to expect, learn more about your childbirth choices, and plan for your baby’s birth. Data shown are for 2014. Most of the information is given in percentages of all deliveries occurring in the hospital during a given year. For example, if 20 births out of 100 are by cesarean section, the cesarean section rate will be 20 percent. If external fetal monitoring is used in 50 out of 100 births, or one-half of all births, the rate will be 50 percent. This information alone doesn’t tell you that one hospital is better than another. If a hospital has fewer than 200 births per year, the use of special procedures in just a few births could change its rates. The types of births could affect the rates as well. Some hospitals offer specialized services to women who are expected to have complicated or high-risk births, or whose babies are not expected to develop normally. These hospitals can be expected to have higher rates of the special procedures than hospitals that do not offer these services. This information also does not tell you about your doctor’s or nurse-midwife’s practice. However, the information can be used when discussing your wishes with your doctor or nurse-midwife, and to find out if his or her use of special procedures is similar to or different from that of the hospital.

Chapel Hill 2007 Approved by Advisor: Suzanne West Reader: Elizabeth Andrews Reader: Patricia Tennis Reader: John Thorp Reader: Andrew Olshan © 2007 Scott T Devine ALL RIGHTS RESERVED - ii- ABSTRACT Scott T. Devine The Identification And Validation Of Neural Tube Defects In The General Practice Research Database (Under the direction of Dr. Suzanne West) Background: Our objectives were to develop an algorithm for the identification of pregnancies in the General Practice Research Database (GPRD) that could be used to study birth outcomes and pregnancy and to determine if the GPRD could be used to identify cases of neural tube defects (NTDs). Methods: We constructed a pregnancy identification algorithm to identify pregnancies in 15 to 45 year old women between January 1, 1987 and September 14, 2004. The algorithm was evaluated for accuracy through a series of alternate analyses and reviews of electronic records. We then created electronic case definitions of anencephaly, encephalocele, meningocele and spina bifida and used them to identify potential NTD cases. We validated cases by querying general practitioners (GPs) via questionnaire. Results: We analyzed 98,922,326 records from 980,474 individuals and identified 255,400 women who had a total of 374,878 pregnancies. There were 271,613 full-term live births, 2,106 pre- or post-term births, 1,191 multi-fetus deliveries, 55,614 spontaneous abortions or miscarriages, 43,264 elective terminations, 7 stillbirths in combination with a live birth, and 1,083 stillbirths or fetal deaths.

  • Presumptive Fertility and Fetoconsciousness: the Ideological Formation of ‘The Female Patient of Reproductive Age’
    PRESUMPTIVE FERTILITY AND FETOCONSCIOUSNESS: THE IDEOLOGICAL FORMATION OF ‘THE FEMALE PATIENT OF REPRODUCTIVE AGE’ A Thesis Submitted to the Temple University Graduate Board In Partial Fulfillment of the Requirements for the Degree MASTER OF ARTS by Emily S. Kirchner May 2017 Thesis Approvals: Nora L. Jones, PhD, Thesis Advisor, Center for Bioethics, Urban Health, and Policy i ABSTRACT Presumptive fertility is an ideology that leads us to treat not only pregnant women, but all female patients of reproductive age, with the presumption that they could be pregnant. This preoccupation with the possibility that a woman could be pregnant compels medical and social interventions that have adverse consequences on women’s lived experiences. It is important to pause now to examine this ideology. Despite our social realities -- there is a patient centered care movement in medical practice, American women are delaying and forgoing childbearing, abortion is safe and legal -- there is still a powerful medical and social process that subjugates womens’ bodies and lived experiences to their potential of being a mother. Fetoconsciousness, preoccupation with the fetus or hypothetical, not-yet-conceived, fetus privileges its potential embodiment over its mother’s reality. As a set of values that influence our beliefs, attitudes, and behaviors, the ideology of presumptive fertility is contextualized, critiqued, and challenged. ii TABLE OF CONTENTS ABSTRACT………………………………………………………………………………ii CHAPTER 1: INTRODUCTION…….….……………...……………………………...…1 CHAPTER 2: TRACING
