Quantification of force applied during external cephalic version. / CUHK electronic theses & dissertations collectionJanuary 2005 (has links)
External cephalic version (ECV) involves turning a fetus in utero by manipulation through the maternal abdomen and the uterine wall. / Many clinicians and patients, however, still decline ECV in favour of Caesarean section. This could be due to the lack of experience of ECV, and fear of complications or pain during the version. / Summary. The force applied during ECV can be measured and analysed using a customized pair of gloves incorporating piezo-resistive pressure sensors and suitable analytical software. The degree of force required for a successful version is highly variable. Failure of version is not usually due to insufficient force. Uterine tone is the most important factor affecting the degree of force applied during a version attempt. The degree of force applied is associated with the changes in fetal cerebral blood flow after ECV, and the amount of pain perceived by the patients. (Abstract shortened by UMI.) / The lack of information in this area is primarily due to the lack of a suitable device that would allow measurements of the force applied without interfering with the ECV. A suitable device would therefore have to be sufficiently robust so that it could be worn on the hands, durable so that it could be used repeatedly, incorporate multiple individual sensors, each of which is capable of making dynamic and mutually independent measurements during the version procedure. / There is no report in the literature on quantification of the force applied during ECV. It is also unknown whether the degree of force applied is related to the version outcome. In particular, it is unclear whether a failed attempt is related to insufficient force, or whether an increase in force may help to achieve version after a failure. Furthermore, it is also not known if any patients' factors may influence how much force is applied through the operator's hands. Although the chance of successful version could be predicted by some clinical factors, whether these factors may also affect the degree of applied force is not known. / This thesis reports on the design and development of a suitable measuring device fulfilling the requirements described above. In addition, it will test a number of hypotheses relating to the degree of force applied during ECV and clinical feto-maternal parameters and outcomes, in a study cohort of 92 patients. / Leung Tak Yeung. / "April 2005." / Source: Dissertation Abstracts International, Volume: 67-07, Section: B, page: 3717. / Thesis (M.D.)--Chinese University of Hong Kong, 2005. / Includes bibliographical references (p. 155-174). / Electronic reproduction.

Sätesförlossningar : Handläggning och utfall hos mödrar och barn vid vaginal förlossning och kejsarsnittGrälls, Jenny January 2013 (has links)
Background: The incidence of caesarean section for breech presentation has reached approximately 90 % in Sweden. In many of these cases, by means of specific selection criteria, it would be as safe to plan for vaginal breech delivery. Aim: The objective of this study was to investigate differences in management and to compare maternal and fetal outcomes according to delivery mode of breech presentation; vaginal vs. caesarian section. The study included breech presentation in full term singleton pregnancies at the UppsalaUniversityHospital, Uppsala, Sweden (UAS). Method: The study was based on medical record data with a retrospective, descriptive, comparative design with quantitative approach. The method for data collection was a manual review of patient records using a structured questionnaire. Results: Of the women with children in breech presentation during the period studied, 11 % gave birth vaginally. Mother's wish was the most common cause of caesarean section. The group with caesarean section included more first-time mothers, longer length of stay at the hospital, increased bleeding and need for pain medication, separation from the child, later lactation and earlier introduction of formula. Vaginally delivered mothers had increased incidence of straight urine catheterization postpartum and of infants with lower Apgar scores. Conclusion: This study does not support the suggestion that it would be safer to give birth by caesarean section for breech presentation in cases where the woman at full term meets strict selection criteria. Instead of applying medical criteria, the decision regarding mode of delivery was more often left up to the mother.

Breech deliveries in Tygerberg Academic Hospital : maternal and neonatal outcomes of vaginal and abdominal deliveries - a case-controlled studyLindeque, L. X. 12 1900 (has links)
Thesis (MMed)--Stellenbosch University, 2011. / ENGLISH ABSTRACT: The Objective: To review the difference in short term neonatal and maternal outcomes
among singleton infants with breech presentation delivered by vaginal or elective caesarean
section route at term, at Tygerberg Academic Hospital (TBH) in Cape Town.
The study design was a retrospective case control study.
Method:
Part I
A total of 120 patients were selected. 60 vaginal breech deliveries and 60 elective caesarean
sections for breech presentation (comprising the control group). 60 cases of vaginal
deliveries were collected and 60 control cases of planned elective caesarean sections, where
the indication for CS was breech presentation, were collected in the same manner.
Part II
Nineteen registrars completed a questionnaire regarding their subjective experiences of
vaginal breech deliveries at Tygerberg Academic Hospital.
Results:
Part I
An analysis of the results found statistically significant differences in maternal ages between
the two groups, with younger women delivering by CS; gravidity and parity was lower in the
CS group; blood loss was observed to be higher in the CS group with more women requiring
a blood transfusion when compared to vaginal delivery; there were more neonatal
admissions in the vaginal delivery group as well as more birth trauma, neonatal seizures and
death in this group; Apgar scores were higher in the CS group and finally, neonates born by
CS were more commonly discharged at the same time as their mothers in the CS group.
Part II
When analyzing the registrar questionnaire it can be noted that although clinicians are
performing an adequate number of breech vaginal deliveries, with an average of 10
deliveries per year, the skills training for clinicians is invaluable. Not all registrars learned
skills from a senior clinician and skills training in skills labs are essential for initial and even
continual training of these clinicians. It is suggested that these skills training programs be made compulsory for all registrars and that a biyearly attendance and completing of such a
course be mandatory for those wishing to work in the labour ward.
Conclusions:
Although not statistically significant, there was more morbidity and mortality associated
with vaginal breech delivery. / AFRIKAANSE OPSOMMING: Doel: Om die korttermyn neonatale en moederlike uitkomste van enkeling swangerskappe
met stuitligging wat vaginaal of met elektiewe keisersnee verlos is by die Tygerberg
Akademiese Hospitaal in Kaapstad, te bepaal.
Die werkstuk is ‘n retrospektiewe gekontroleerde-gevallestudie.
Metode:
Deel 1
‘n Totaal van 120 pasiënte is gekies. 60 gevalle van vaginale stuitverlossings en 60 kontrolegevalle
van beplande elektiewe keisersnitte waar die indikasie stuitligging was.
Deel 2
Negentien kliniese assistente het die vraelys oor hul persoonlike ervaring van vaginale
stuitverlossing by die Tygerberg Akademiese Hospitaal ingevul.
Resultate:
Deel 1
‘n Ontleding van die resultate wys statisties betekenisvolle verskille in die moederouderdom
van die twee groepe, met meer jong vroue wat met keisernit geboorte gee.
Graviditiet en pariteit was laer in die keisersnit-groep. Bloedverlies was hoër in die
keisersnit-groep en in vergelyking met die vaginale verlossings met meer vroue wat
bloedoortapping benodig. In die vaginale verlossingsgroep was meer neonatale toelatings
nodig asook meer geboortetrauma, neonatale konvulsies en sterftes. Apgar-tellings was
hoër in die keisersnitgroep en neonate wat met ‘n keisersnitte gebore is, is meer dikwels
saam met hul moeders ontslaan.
Deel II
Ontleding van die vraelys vir kliniese assistente wys dat hoewel klinici ‘n genoegsame getal
van gemiddeld 10 vaginale stuitverlossings per jaar uitvoer, vaardigheidsopleiding vir klinici
van onskatbare waarde sal wees.
Nie alle kliniese assistente leer vaardighede by senior klinici nie en opleiding in ‘n
vaardigheidslaboratorium is noodsaaklik vir die aanvanklike en selfs voortdurende opleiding
van dié kliniese assistente. Dit word voorgestel dat hierdie vaardigheidkursusse verpligtend gemaak word vir alle kliniese asssistente en bywoning en voltooiing van die kursus twee
maal per jaar verpligtend moet wees vir diegene wat in ‘n kraamsaal wil werk.
Gevolgtrekking:
Vaginale stuitverlossings, hoewel nie stastisties betekenisvol nie, het met meer morbiditeit
en sterftes gepaardgegaan.

The obstetric outcome of women who had successful external cephalic version for breech presentation at termKader, Rahel 12 1900 (has links)
Thesis (MMed)-- Stellenbosch University, 2013. / ENGLISH ABSTRACT: AIM: Review outcome of pregnancies following successful external cephalic version (ECV) for breech presentation at term, particularly the caesarian section (CS) rate.
ECV is a safe procedure with a minimal cost implication that can reduce non-cephalic presentation at onset of labour at term. The outcome of pregnancies following successful ECV is certainly of interest. A meta analysis of studies done between 1997 and 2004, found that pregnancies after successful ECV at term were not the same as those with spontaneous cephalic presentations and was associated with a CS rate twice that in pregnancies with spontaneous cephalic presentations. The conclusion was that pregnancies after successful ECV should not be considered the same as normal pregnancies. In a matched retrospective analysis of CS risk after successful ECV, done in the USA, it was concluded that CS delivery and operative vaginal delivery rates following successful ECV, were not increased. To date there are no such studies in South Africa.
METHODOLGY: A retrospective descriptive study was done to audit all successful ECV’s done at the Fetal Evaluation Clinic (FEC) of Tygerberg Academic Hospital. The electronic data from the FEC was searched for successful ECV patients. The facilities where these patients delivered were identified. The outcome of the pregnancies was determined from patient files and/or the labor registers. The relevant information of each patient was captured. All file reviews and data capturing was done by the principal investigator.
RESULTS: A total of 78 patients were included in the study. The median age was 28.7 years with a range from 17 to 40 years, the median parity 1 and the range 0 to 6 and the median body mass index 27.2 and the range 18.2 to 45.0. The method of determining gestational age is known in 71 (91%) patients of whom 37 (52%) had an early ultrasound examination. The median gestational age at ECV was 37 weeks with the inter quartile range 36 to 38 weeks. The median ECV to delivery time was 2 weeks with the inter quartile range 1 to 4 weeks. Higher levels of care were required at time of delivery by 47 (60.3%) patients. Vaginal deliveries occurred in 49 patients and 29 (37.2%) had CS. The most common indications for CS were cephalo pelvic disproportion 8, fetal distress 6, reversion back to breech presentations 4 and other abnormal presentations 4 (2 face presentations and 2 transverse lies). The mean birth weight of the babies was 3360g and the range 2100 to 4655g. On comparing the groups that had vaginal deliveries and CS, only nulliparous patients had a significantly (p=0.02) higher risk for CS.
CONCLUSIONS: Following successful ECV all patients need to be carefully followed up for possible reversion to breech presentation or transverse lie. Nulliparous and gravid 2 para 1 patients with a previous CS need to be delivered in hospitals with CS facilities. Further studies are required to assess whether successful ECV results in more face presentations. / AFRIKAANSE OPSOMMING: DOELWIT: Om die uitkoms van swangerskappe na suksesvolle eksterne kefaliese kerings (EKK) vir stuit presentasies op voltyd, spesifiek die keisersnit (KS) insidensie te bepaal.
EKK is ‘n veilige prosedure wat teen minimale koste die nie-kefaliese presentasies op voltyd kan verminder. Die uitkoms van swangerskappe na suksesvolle EKK is van belang. ‘n Meta-analise van studies gedoen tussen 1997 en 2004 vind dat swangerskappe na suksesvolle EKK op voltyd nie dieselfde is vergeleke met spontane kefaliese presentasies nie en gepaard gaan met ‘n KS koers tweekeer hoër as dié met spontane kefaliese presentasies op voltyd. Die gevolgtrekking was dat swangerskappe na suksesvolle EKK nie as normale swangerskappe beskou moet word nie. In ‘n gepaarde retrospektiewe ontleding van die KS risiko wat in die VSA gedoen is, word gevind dat die KS en operatiewe vaginale verlossing koerse na suksesvolle EKK, nie verhoog is nie. Tot op hede is daar geen studies hieroor in Suid-Afrika gedoen nie.
METODE: ’n Retrospektiewe beskrywende studie is gedoen om all suksesvolle EKK wat by die Fetale Evaluasie Kliniek (FEK) gedoen is te oudit. ‘n Elektroniese data soektog van suksesvolle EKK by die FEK is gedoen. Die instellings waar die pasiënte verlos is, is vasgestel. Die uitkoms van die swangerskappe is bepaal deur pasiënt lêers en/of die kraamregisters na te gaan. Die relevant inligting oor elke pasiënt is versamel.
RESULTATE: ‘n Totaal van 78 pasiënte is by die studie ingesluit. Die mediane ouderdom was 28.7 jaar met ‘n reikwydte van 17 tot 40 jaar, die mediane pariteit was 1 met ‘n reikwydte van 0 tot 6 en die mediane liggaamsmassa indeks 27.2 met ‘n reikwydte van 18.2 tot 45.0. Die metode waavolgens swangerskapsduurte bepaal is, was bekend in 71 (91%) van pasiënte, waarvan 37 (52%) vroeë ultraklank ondersoeke gehad het. Die mediane swangerskapsduurte tydens die EKK was 37 weke met die interkwartiele interval 36 tot 38 weke. Die mediane EKK tot verlossing tydsverloop was 2 weke met die interkwartiele interval 1 tot 4 weke. Hoër vlakke van sorg was nodig ten tye van die verlossing by 47 (60.3%) van pasiënte. Van die pasiënte het 49 vaginale verlossings en 29 (37.2%) KS gehad. Die mees algemene indikasies vir KS was skedel-bekken disproporsie 8, fetale nood 6, terugkeer na stuitpresentasie 4 en abnormale presentasies 4 (2 aangesigsliggings en 2 transversliggings). Die gemiddelde geboorte gewig van die babas was 3360g en die reikwydte 2100 tot 4655g. Wanneer die groep wat vaginale verlossing en KS gehad het vergelyk word, het slegs nullipareuse pasiënte ‘n betekenisvolle (p=0.02) hoër risiko vir KS gehad.
GEVOLTREKKING: Na suksesvolle EKK moet alle pasiënte noukeurig opgevolg word vir terugkeer na ‘n stuit presentasie of transversligging. Nullipareuse en gravida 2 para 1 pasiënte met ‘n vorige KS moet in hospitale met KS fasiliteite verlos word. Verdere studies is nodig om te bepaal of suksesvolle EKK meer aangesig presentasies tot gevolg het.

Examination of Birth Outcomes with Mode of Delivery for Breech PresentationArey, Kelly Marie 01 January 2007 (has links)
Introduction: Approximately 3% to 4% of all pregnancies at term will have a fetus with a breech presentation. Studies have shown that the US has almost completely abandoned vaginal delivery for breech presentation through the influence of the "Term Breech Trial" (TBT) which concluded that a policy of planned caesarian section would reduce perinatal mortality, late neonatal mortality, and serious neonatal morbidity by approximately two-thirds for term fetuses. However, the recommendations are still being challenged by others.Objectives: The purpose of the study was to describe who in Virginia is having a vaginal delivery for a breech presentation and to determine if there is a difference in birth outcome based on mode of delivery for breech presentation of term infants.Methods: This population-based study used all birth records for term infants with breech presentation delivered between 1996 and 2005. Data were obtained from the Center for Health Statistics at the Virginia Department of Health. Descriptive statistics were done to characterize vaginal and caesarean section deliveries. These methods were compared using logistic regression for infant mortality and 5-minute Apgar scores as dependent variables.Results: In Virginia, over the last ten years, the prevalence of vaginal deliveries dropped from 13.1% to 6.6% for full term infants with a breech presentation, a decrease of almost 50%. Black women, younger mothers between the ages of 12 and 24, and women with less than or equal to a high school education had the highest occurrence of vaginal births. In the logistic models, the risk for infant death was highest for black women [OR = 1.93; (1.56, 2.38)], women with more than 13 prenatal visits [OR = 1.25; (1.02, 1.53) for 13-15 visits, OR = 2.33; (1 .82, 2.98) for >15 visits], infants who had a low birth weight [OR = 2.8 1 ; (2.08, 3.79)], and women who had a vaginal delivery [OR = 1.42; (1.10, 1.84)] The characteristics that were associated with a lower 5-minute Apgar score for breech infants delivered vaginally included the mother's method of payment, [Medicaid OR 1.75; (1.03, 2.97) and self pay OR 2.33; (1.13, 4.83)], low birth weight [OR = 2.54; (1.24, 5.22)], and delivery type [OR = 4.71; (2.95, 7.52)].Discussion/Conclusions: Our data showed that women who have a vaginal delivery for a term breech infant were more likely to be black, 12-24 years of age, no private insurance, and fewer prenatal visits and was associated with higher infant mortality and lower 5-minute Apgar scores. However, our results indicated that these infants had other significant problems, as indicated by the association with a high number of prenatal visits. Therefore, having physicians who are experienced in delivering breech infants vaginally, careful exclusion of risk factors and, educating the patient about the risks and complications of a vaginal delivery for breech fetuses could help decrease the potential risks for the mother and the infant.

Barnmorskors erfarenheter av att handlägga vaginala sätesförlossningar : En kvalitativ intervjustudie / Midwives´experiences of handling vaginal breech birthsJeppås, Hilda, Strand, Evelina January 2024 (has links)
Bakgrund: I Sverige år 2022 förlöstes färre än ett av tio barn som låg i sätesbjudning genom vaginal sätesförlossning. Om denna siffra slås ut på antalet barnmorskor i Sverige blir det tydligt att vaginala sätesförlossningar är något som är svårt att få praktisk erfarenhet av som barnmorska. Barnmorskan förväntas ha kompetens att kunna handlägga en vaginal sätesförlossning. Det råder nationell enighet i att vaginala sätesförlossningar bör handläggas av barnmorskor och obstetriker med god erfarenhet. Att uppnå god erfarenhet av vaginala sätesförlossningar kan ses som ett problem när majoriteten av sätesfödslarna sker med kejsarsnitt. Syfte: Att beskriva barnmorskors erfarenheter av att handlägga vaginala sätesförlossningar Metod: Datainsamlingen utfördes genom tio enskilda intervjuer. Som analysmetod valdes en kvalitativ innehållsanalys med en induktiv ansats. Resultat: Insamlade data genererade tre kategorier, Ryggsäcken barnmorskan bär på, Handläggning vid vaginal sätesförlossning och Faktorer som påverkar trygghet vid vaginal sätesförlossning med totalt åtta underkategorier. Barnmorskors syn och inställning till vaginala sätesförlossningar påverkas av tidigare erfarenheter. Barnmorskorna påtalar vikten av en lugn miljö vid en vaginal sätesförlossning samt diskuterar val av förlossningsposition. Teamet har en betydande roll för barnmorskornas känsla av trygghet och det uttrycks ett behov av utökad träning kring vaginala sätesförlossningar. Slutsats: Samtliga barnmorskor i studien uttrycker en vilja att bistå fler sätesförlossningar men att de ser ett behov av ytterligare träning och kompetensutveckling. Genom utökad träning och kompetensutveckling inom detta område kan teamet stärkas vilket på sikt skulle kunna öka barnmorskans trygghet vid handläggningen av vaginala sätesförlossningar. / Background: In Sweden in 2022, fewer than one in ten babies who were breech were delivered by vaginal breech birth. If this figure is divided between the number of midwives in Sweden it is difficult to gain practical experience with vaginal breech births as a midwife. The midwife is expected to have the competence to handle a vaginal breech birth. There is national consensus that vaginal breech births should be managed by midwives and obstetricians with good experience. Achieving that good experience with vaginal breech births can be a problem when most breech births are by caesarean section. Aim: To describe midwives' experiences of handling vaginal breech births Method: The data collection was carried out through ten individual interviews. A qualitative content analysis with an inductive approach was chosen as the analysis method. Results: Collected data generated three categories, The backpack the midwife carries, Handling of vaginal breech birth and Factors affecting safety during vaginal breech birth with a total eight subcategories. Midwives' views and attitudes towards vaginal breech births are influenced by previous experiences. The midwives point out the importance of a calm environment during a vaginal breech birth and discuss the choice of birth position. The team has a significant role in the midwives' sense of security and there is a need for increased training around vaginal breech births. Conclusion: All midwives in the study expressed a desire to assist more breech births, but they are aware of the need for continiuous training and skill development. Through increased training and competence development in this area, the team can be strengthened, which in the long run could increase the midwife's safety when handling vaginal breech births.

Présentation foetale en siège en fin de grossesse : effet des interventions et des attitudes professionnelles sur le vécu des femmes / Term breech presentation : effect of interventions and professional attitudes on women's experiencesGuittier, Marie-Julia 06 November 2013 (has links)
Contexte : Le management de la présentation foetale en siège est complexe car la littérature scientifique est contrastée. Objectif : Mettre en évidence les effets des attitudes et des interventions professionnelles sur le vécu des femmes. Méthodes : Cinq recherches quantitatives et qualitatives, incluant 311 participantes, ont été menées à la maternité des Hôpitaux Universitaires de Genève. Résultats : Les femmes doivent souvent faire un deuil par anticipation de l'accouchement idéalisé. Elles sont très motivées à tenter de corriger la malposition foetale. 69% des participantes ont recours aux médecines alternatives et complémentaires pour se soigner. 68% des participantes ont qualifié la tentative de version céphalique externe (VCE) de « forte à insupportable. Un accompagnement par hypnose ne réduit pas l'intensité de la douleur, comparé à un accompagnement par une sage-femme (échelle visuelle analogique : 6,0 vs 6,3 /10 respectivement, p=0.25). Pour le choix du mode d'accouchement les femmes ont rapporté des conflits décisionnels majeurs. L'information médicale est souvent perçue en faveur de la césarienne élective. Le sentiment de contrôle, les émotions et les premiers instants avec le nouveau-né sont perçus différemment selon le mode d'accouchement, en défaveur de la césarienne en urgence. Conclusion : Un processus émotionnel et décisionnel inattendu et souvent difficile est associé au diagnostic de siège. Développer des outils d'aide à la décision pour la femme, et des techniques de relation d'aide pour les professionnels faciliteraient ces processus. La prise en charge de la douleur durant la tentative de VCE est indispensable / Context: Management of breech remains complex due to divergence of practices and recommendations reported in the literature. Objective: To highlight the effects of health professionals' interventions on women's experiences. Methods: Five research studies qualitative were conducted at the University Hospitals of Geneva, including a total of 311 participants. Two studies used a method with interviews and thematic analysis, two used a quantitative method with a statistical analysis, and one used a mixed methods' design. Results: Breech diagnosis often requires anticipating a disappointment of an idealized childbirth. Women demonstrate a strong motivation to try to turn their fetus. 69% of women use complementary and alternative medicine (CAM) for their treatment. 68% of participants qualified external cephalic version (ECV) as "strong to unbearable". An accompaniment by a hypnotist compared to a midwife did not decrease pain intensity (visual analogic scale: 6.0 vs 6.3/10, respectively; p=.25). For the choice of breech delivery mode, women reported strong decisional conflicts. Medical information is often perceived in favour of a planned caesarean. Feelings of control, emotions and the first moments with the newborn are perceived differently and, notably, negatively in the case of emergency ceasarean section. Conclusion: A difficult emotional and decision-making process is associated with term breech. Use of CAM should be considered by professionals. Developing tools to assist women, and relationship techniques for professionals could facilitate these processes. Reduction of pain during ECV is necessary
