The Pelosi-type versus the modified Misgav-Ladach: a randomized trial of two surgical techniques for cesarean section

Cesarean section (CS) is now the most common major surgical procedure performed on women worldwide. A quarter of deliveries in Spain are performed by cesarean section. With the increasing rates of the operation, there is the need to use evidence-based techniques to optimize outcomes and minimize complications. The goal of this study is to employ a well-designed randomized controlled trial to evaluate the intraoperative blood loss of two surgical techniques for cesarean section, the Pelosi-type and the modified Misgav-Ladach. The trial will take place in Hospital Universitari de Girona Dr. Josep Trueta From 2014 to 2015, 512 pregnant women undergoing delivery by their first lower segment cesarean section in this center will be selected through a consecutive nonprobability sampling. We will collect the main obstetrical characteristics, intraoperative outcomes, short-term outcomes for the baby and postoperative outcomes. We will evaluate the intraoperative blood loss by comparing the changes in hemoglobin levels, pre and postoperatively. Patients will be followed during the postoperative period and in a two-week postoperative appointment. We will analyze the continuous variables, such as the differences in hemoglobin levels, using an unpaired two-sided Student’s t-test, while for the categorical variables Fischer’s exact test will be used

Impact of maternity care policy in Catalonia: a retrospective cross-sectional study of service delivery in public and private hospitals

Background: As a result of the growing number of interventions that are now performed in the context of maternity care, health authorities have begun to examine the possible repercussions for service provision and for maternal and neonatal health. In Spain the Strategy Paper on Normal Childbirth was published in 2008, and since then the authorities in Catalonia have sought to implement its recommendations. This paper reviews the current provision of maternity care in Catalonia. Methods: This was a descriptive study. Hospitals were grouped according to their source of funding (public or private) and were stratified (across four strata) on the basis of the annual number of births recorded within their respective maternity service. Data regarding the distribution of obstetric professionals were taken from an official government survey of hospitals published in 2010. The data on obstetric interventions (caesarean, use of forceps, vacuum or non-specified instruments) performed in 2007, 2010 and 2012 were obtained by consulting discharge records of 44 public and 20 private hospitals, which together provide care in 98% of all births in Catalonia. Proportions and confidence intervals were calculated for each intervention performed in all full-term (3742 weeks) singleton births. Results: Analysis of staff profiles according to the stratification of hospitals showed that almost all the hospitals had more obstetricians than midwives among their maternity care staff. Public hospitals performed fewer caesareans [range between 19.20% (CI 18.84-19.55) and 28.14% (CI 27.73-28.54)] than did private hospitals [range between 32.21% (CI 31.78-32.63) and 39.43% (CI 38.98-39.87)]. The use of forceps has decreased in public hospitals. The use of a vacuum extractor has increased and is more common in private hospitals. Conclusions: Caesarean section is the most common obstetric intervention performed during full-term singleton births in Catalonia. The observed trend is stable in the group of public hospitals, but shows signs of a rise among private institutions. The number of caesareans performed in accredited public hospitals covers a limited range with a stable trend. Among public hospitals the highest rate of caesareans is found in non-accredited hospitals with a lower annual number of births.

Ferimento transfixante de útero em gestante

In de past 50 years, maternal mortality rates have declined, in contrast, the number of deaths due to injury during pregnancy is on the rise. The authors report a case of 24° week pregnant woman victim of penetrating abdominal trauma by gunshot who sustained a grade I11 transfixing injury of the uterine fundus. Treatment was conservative regarding the fetus. Hysteroraphia of the injuries was executed with closure of both penetrating orifices. Obstetrical-gynecological evaluation and echogram documented letal viability in the post-operative period. Post-operative follow-up was performed with periodical echograms up to delivery on the ninth month. Clinical findings, treatment and follow-up will be discussed.

Leiomiomas do esôfago removidos por vídeo-toracoscopia

This report describes three cases of esophageal leiomyomas successfully resected by thoracoscopy. Surgical enucleation through minimally invasive surgery is the treatment of choice for esophageal leiomyoma. The conventional approach through a formal thoracotomy has the potential of causing excessive pain and patient discomfort. Moreover, the hospital stay and the recovery period are prolonged. Indications for surgery were based mainly on the size of the mass (<4 cm) and the presence of dysphagia. In one case there was a clear suspicion of malignancy. The tumour was located in the lower thoracic esophagus (case 1), in the middle thoracic esophagus (case 2) and in the upper esophagus (case 3). The CT was useful in identifying the relationship between the lesion and the organs of the mediastinum. The barium swallow study was able to locate the lesion along the esophagus. The endosonography determined the boundaries of the lesions. A right thoracoscopic approach was undertaken. Dissection of the esophagus around its entire perimeter was never necessary because all tumours were anterior or right sided. The tumours were better grasped with a traction suture than with forceps. The hidrodissection was very helpful. The water-soluble contrast swallow, performed on the fourth postoperative day, was normal. Clinical results were satisfactory in all patients. Biopsies should never be performed when the mucosa overlying is normal.

Assessment of pelvic floor by three-dimensional-ultrasound in primiparous women according to delivery mode: initial experience from a single reference service in Brazil

PURPOSE: To evaluate changes to the pelvic floor of primiparous women with different delivery modes, using three-dimensional ultrasound. METHODS: A prospective cross-sectional study on 35 primiparae divided into groups according to the delivery mode: elective cesarean delivery (n=10), vaginal delivery (n=16), and forceps delivery (n=9). Three-dimensional ultrasound on the pelvic floor was performed on the second postpartum day with the patient in a resting position. A convex volumetric transducer (RAB4-8L) was used, in contact with the large labia, with the patient in the gynecological position. Biometric measurements of the urogenital hiatus were taken in the axial plane on images in the rendering mode, in order to assess the area, anteroposterior and transverse diameters, average thickness, and avulsion of the levator ani muscle. Differences between groups were evaluated by determining the mean differences and their respective 95% confidence intervals. The proportions of levator ani muscle avulsion were compared between elective cesarean section and vaginal birth using Fisher's exact test. RESULTS: The mean areas of the urogenital hiatus in the cases of vaginal and forceps deliveries were 17.0 and 20.1 cm², respectively, versus 12.4 cm² in the Control Group (elective cesarean). Avulsion of the levator ani muscle was observed in women who underwent vaginal delivery (3/25), however there was no statistically significant difference between cesarean section and vaginal delivery groups (p=0.5). CONCLUSION: Transperineal three-dimensional ultrasound was useful for assessing the pelvic floor of primiparous women, by allowing pelvic morphological changes to be differentiated according to the delivery mode.

Chromosomal abnormalities in couples with recurrent first trimester abortions

PURPOSE: To investigate the prevalence of chromosomal abnormalities in couples with two or more recurrent first trimester miscarriages of unknown cause. METHODS: The study was conducted on 151 women and 94 partners who had an obstetrical history of two or more consecutive first trimester abortions (1-12 weeks of gestation). The controls were 100 healthy women without a history of pregnancy loss. Chromosomal analysis was performed on peripheral blood lymphocytes cultured for 72 hours, using Trypsin-Giemsa (GTG) banding. In all cases, at least 30 metaphases were analyzed and 2 karyotypes were prepared, using light microscopy. The statistical analysis was performed using the Student t-test for normally distributed data and the Mann-Whitney test for non-parametric data. The Kruskal-Wallis test or Analysis of Variance was used to compare the mean values between three or more groups. The software used was Statistical Package for the Social Sciences (SPSS), version 17.0. RESULTS: The frequency of chromosomal abnormalities in women with recurrent miscarriages was 7.3%, including 4.7% with X-chromosome mosaicism, 2% with reciprocal translocations and 0.6% with Robertsonian translocations. A total of 2.1% of the partners of women with recurrent miscarriages had chromosomal abnormalities, including 1% with X-chromosome mosaicism and 1% with inversions. Among the controls, 1% had mosaicism. CONCLUSION: An association between chromosomal abnormalities and recurrent miscarriage in the first trimester of pregnancy (OR=7.7; 95%CI 1.2--170.5) was observed in the present study. Etiologic identification of genetic factors represents important clinical information for genetic counseling and orientation of the couple about the risk for future pregnancies and decreases the number of investigations needed to elucidate the possible causes of miscarriages.

Do induced twin pregnancies influence the obstetric and neonatal results of multiple births born before 32 weeks? Comparison to spontaneous gestation

PURPOSE: To compare obstetric outcomes of induced preterm twin births (under 32 weeks gestation) with those spontaneously conceived. METHODS: Prospective study of twin pregnancies (25 induced and 157 spontaneously conceived) developed over a period of 16 years in a tertiary obstetric center. Demographic factors, obstetric complications, gestational age at delivery, mode of delivery, birth weight and immediate newborn outcome were compared. RESULTS: The analysis of obstetrical complications concerning urinary or other infections, hypertensive disorders of pregnancy, gestational diabetes, fetal malformations, intrauterine fetal death, intrauterine growth restriction and intrauterine discordant growth reveal no significant statistical differences between the two groups. First trimester bleeding was higher in the induced group (24 versus 8.3%, p=0.029). The cesarean delivery rate was 52.2% in spontaneous gestations and 64% in induced gestations. Gestational age at delivery, birth weight, Apgar scores at first and fifth minutes, admissions to Neonatal Intensive Care Unit and puerperal complications show no statistically significant differences between the two groups. These results were independent of chorionicity and induction method. CONCLUSION: The mode of conception did not influence obstetric and neonatal outcomes. Although induced pregnancies have higher risk of first trimester bleeding, significant differences were not observed regarding other obstetric and puerperal complications and neonatal results.

Celioscopic liver biopsy in silver catfish (Rhamdia quelen)

Endosurgery has been used for assessment of fish celomatic cavity, as well as for obtaining biopsies for organic analysis. Such minimally invasive access may also be used for the analysis of environmental impact on biomarkers of pollution. In Brazil, studies and literature regarding the use of celioscopy in fish are sparse. The purpose of the current study was to develop a two-port celioscopy technique to obtain liver biopsy in silver catfish (Rhamdia quelen). Six adult female silver catfish were used. The animals were anesthetized and the inspection of the celomatic cavity were performed using a telescope and celioscopic-guided liver biopsy were taken using laparoscopic Kelly forceps. On the early postoperative period, the animals were released in a confined water reservoir where mortality could be checked. The liver samples were sent for histological assessment. There were no complications during surgery on early postoperative period. It was possible to visualize meticulously several organs (liver, spleen, stomach, pancreas, swim bladder, ovaries, bowel and transverse septum). In conclusion, the surgical technique and the anesthetic protocol proposed were suitable to perform liver biopsies in silver catfish and provided low morbidity.

Analyse des facteurs institutionnels associés à la mortalité maternelle : Une étude nationale dans les maternités chirurgicales au Sénégal

Résumé Objectif : Identifier les facteurs institutionnels qui influencent la mortalité maternelle (MM) hospitalière dans les maternités chirurgicales au Sénégal. Méthode : cette étude est une analyse secondaire des données de la troisième Enquête Nationale sur la Couverture Obstétrico-chirurgicale au Sénégal en 2001. Les données analysées, issues des fiches d'activité des maternités, comptaient pour 38,239 admissions en obstétrique dans 19 hôpitaux et 450 décès maternels. Les taux de mortalité maternelle hospitalière (TMMH) brut et ajusté ont été utilisés comme variables dépendantes. Le TMMH ajusté sur les caractéristiques de la clientèle ('cases-mix') a été estimé pour chaque établissement de santé par la méthode de standardisation directe. Les indicateurs de la qualité des structures, de la gestion des ressources, et un score de qualité ont été utilisés comme variables indépendantes pour prédire la MM hospitalière. Les tests de Mann-Whitney et de Kruskal-Wallis ont été utilisés pour analyser l’association entre les variables indépendantes, le score de qualité et la MM. Une analyse multivariée a été utilisée pour estimer l’impact du score de qualité sur la MM, en tenant compte de la situation géographique (Dakar versus autre région).Résultats: En analyse bivariée, la présence d'anesthésiste, la disponibilité de boîtes de césarienne complète et la supervision de tous les accouchements par du personnel qualifié sont les facteurs institutionnels associés significativement à une réduction du TMMH brut. Quant au TMMH ajusté ce sont la présence de scialytique, la disponibilité du sulfate de magnésium, l'utilisation des guides de pratiques cliniques (GPC) pour la prise en charge des complications obstétricales. Le score de qualité est associé significativement au TMMH brut, y compris en analyse multivariée, mais pas au TMMH ajusté. Conclusion : La disponibilité du Sulfate de magnésium, et du scialytique pourrait contribuer à la réduction de la MM. En complément, une réorganisation adéquate des ressources pour réduire la disparité géographique rurale/urbaine est essentielle ainsi qu’une sensibilisation du personnel à l’usage des GPC. De plus, l’assistance par un personnel qualifié de tous les accouchements est nécessaire pour améliorer la qualité des soins et la prise en charge des complications obstétricales.

Analyse de la variation inter-populationnelle du canal obstétrique au sein de trois populations génétiquement différentes

La dystocie représente une des causes principales de la mortalité maternelle et fœtale lors de l’accouchement. Une relation trop étroite entre les dimensions maternelles et fœtales résultent souvent en une césarienne d’urgence. Les manuels obstétricaux actuels proposent qu’une forme gynoïde de la cavité obstétricale est normale car elle favorise une descente fœtale sans difficulté lors de la parturition parce qu’elle est arrondie. Ce mémoire de maîtrise porte sur l’étude de la variation inter-populationnelle de la forme du canal obstétrique chez trois populations génétiquement différentes pour tester si ces populations ont toutes une forme gynoïde ou si elles sont variables morphologiquement. Les cavités pelviennes analysées sont constituées de 59 bassins d’Américaines d’origine européenne, 74 bassins d’Américaines d’origine africaine et 19 bassins de Sadlermiuts. Vingt points anatomiques sur la cavité pelvienne ont été digitalisés à partir du bassin articulé pour permettre une visualisation tridimensionnelle de la forme du canal obstétrique. Une analyse Procrustes suivie d’une analyse en composantes principales ont été faites pour faire ressortir les composantes qui permettent de faire des distinctions entre les trois populations. L’existence d’une relation d’une part entre la taille et/ou la masse et d’autre part la morphologie du canal obstétrique a aussi été explorée. Résultats : La morphologie qui décrit les Sadlermiuts est la forme platypelloïde, soit un diamètre médio-latéral plus grand que le diamètre antéro-postérieur, et ce à tous les détroits. Les Américaines africaines présentent une morphologie qui tend vers une forme gynoïde aux détroits supérieur et moyen, et les Américaines européennes démontrent une morphologie intermédiaire entre les formes gynoïde et androïde au détroit supérieur. Seule la taille du bassin (taille centroïde) est corrélée à des changements de la forme du canal obstétrique pour les détroits supérieur et moyen. Discussion: La forme gynoïde n’est pas représentative de la cavité obstétricale chez les trois populations. Il est possible que la forme platypelloïde des Sadlermiuts soit une conséquence de comportements induisant des changements morphologiques lors du développement squelettique. D’autres études sont requises pour évaluer cette hypothèse.

What are the components of humanized childbirth in a highly specialized hospital? : an organizational case study

Many studies have focused on the concept of humanization of birth in normal pregnancy cases or at low obstetric risk, but no studies, at our knowledge, have so far specifically focused on the humanization of birth in both high-risk, and low risk pregnancies, in a highly specialized hospital setting. The present study thus aims to: 1) define the specific components of the humanized birth care model which bring satisfaction to women who seek obstetrical care in highly specialized hospitals; and 2) explore the organizational and cultural dimensions which act as barriers or facilitators for the implementation of humanized birth care practices in a highly specialized, university affiliated hospital in Quebec. A single case study design was chosen for this thesis. The data were collected through semi-structured interviews, field notes, participant observations, selfadministered questionnaire, relevant documents, and archives. The samples comprised: 11 professionals from different disciplines, 6 administrators from different hierarchical levels within the hospital, and 157 women who had given birth at the hospital during the study. The performed analysis covered both quantitative descriptive and qualitative deductive and inductive content analyses. The thesis comprises three articles. In the first article, we proposed a conceptual framework, based on Allaire and Firsirotu’s (1984) organizational culture theory. It attempts to examine childbirth patterns as an organizational cultural phenomenon. In our second article, we answered the following specific question: according to the managers and multidisciplinary professionals practicing in a highly specialized hospital as well as the women seeking perinatal care in this hospital setting, what is the definition of humanized care? Analysis of the data collected uncovered the following themes which explained the perceptions of what humanized birth was: personalized care, recognition of women’s rights, humanly care for women, family-centered care,women’s advocacy and companionship, compromise of security, comfort and humanity, and non-stereotyped pregnancies. Both high and low risk women felt more satisfied with the care they received if they were provided with informed choices, were given the right to participate in the decision-making process and were surrounded by competent care providers. These care providers who humanly cared for them were also able to provide relevant medical intervention. The professionals and administrators’ perceptions of humanized birth, on the other hand, mostly focused on personalized and family-centered care. In the third article of the thesis, we covered the dimensions of the internal and external components of an institution which can act as factors that facilitate or barriers that prevent, a specialized and university affiliated hospital in Quebec from adopting a humanized child birthing care. The findings revealed that both the external dimensions of a highly specialized hospital -including its history, society, and contingency-; and its internal dimensions -including culture, structure, and the individuals present in the hospital-, can all affect the humanization of birth care in such an institution, whether separately, simultaneously or in interaction. We thus hereby conclude that the humanization of birth care in a highly specialized hospital setting, should aim to meet all the physiological, as well as psychological aspects of birth care, including respect of the fears, beliefs, values, and needs of women and their families. Integration of competent and caring professionals and the use of obstetric technology to enhance the level of certainty and assurance in both high-risk and low risk women are both positive factors for the implementation of humanized care in a highly specialized hospital. Finally, the humanization of birth care approach in a highly specialized and university affiliated hospital setting demands a new healthcare policy. Such policy must offer a guarantee for women to have the place of birth, and the health care professional of their choice as well as those, which will enable women to make informed choices from the beginning of their pregnancy.

Measuring and evaluating quality of care in referral maternities in Mali and Senegal in the context of overlapping interventions

Dans cette thèse, nous décrivons les résultats d’un projet de recherche visant à mesurer et évaluer la qualité des soins obstétricaux des hôpitaux de référence au Mali et au Sénégal. Dans ces pays, la mortalité maternelle hospitalière est élevée et est liée en partie à la pratique médicale inadéquate. Cette recherche a été réalisée dans le cadre de l’étude QUARITE, un essai randomisé en grappe évaluant l’efficacité du programme GESTA International visant à réduire la mortalité maternelle hospitalière. GESTA a été mis en œuvre entre 2008 et 2010 et consistait en la formation des professionnels de santé et en la revue des cas de décès maternels. En parallèle de QUARITE, les programmes de prévention de la transmission du VIH de la mère à l’enfant (PTME) ont été mis à l’échelle à travers les pays. Ces derniers ayant également la capacité d’augmenter la qualité des soins obstétricaux, nous avons donc évalué les effets des deux programmes (GESTA et PTME) sur la qualité des soins. Dans un premier temps, à l’aide d’une recension des écrits nous avons évalué la capacité d’un audit clinique basé sur des critères à mesurer la qualité des soins obstétricaux. Cet audit vérifiait si l’offre des soins avait respecté les critères cliniques définissant la meilleure prise en charge selon l’évidence scientifique et l’avis des experts. Nous avons démontré que cet outil est largement utilisé dans les pays à faibles et moyens revenus, malgré le peu d’évidence sur sa validité (article 1). Dans un deuxième temps, nous avons développé un audit clinique basé sur des critères qui s’applique au contexte ouest-africain et qui a été approuvé par des experts-obstétriciens nationaux et internationaux. À partir des dossiers obstétricaux, les actes médicaux posés pendant le travail et l’accouchement ont été évalués à l‘aide de cet instrument. La qualité des soins a été estimée sous forme de pourcentage de critères atteints. Appliqué dans différents contextes et par différents auditeurs, nous avons démontré que notre instrument est fiable et valide (article 3). Néanmoins, l’expérience de l’audit nous a amenés à nous questionner sur le mauvais remplissage des dossiers médicaux et ses conséquences sur la qualité des soins (article 2). Dans un troisième temps, l’outil a été appliqué à large échelle pour évaluer les effets de l’intervention GESTA (article 4). Nous avons mené une révision de plus de 800 dossiers obstétricaux dans 32 hôpitaux de référence (16 bénéficiaires de l’intervention et 16 non-bénéficiaires). Grâce à cet audit clinique, nous avons démontré que le programme GESTA contribue à l’amélioration de la qualité des soins, spécifiquement l’examen clinique lors de l’admission et le suivi après l’accouchement. Dernièrement, nous avons utilisé cet instrument afin d’évaluer les effets des programmes de PTME sur la qualité des soins obstétricaux (article 5). Notre travail a documenté que seulement certaines composantes du programme de PTME améliorent la qualité des soins telles que la formation des professionnels et les services complémentaires en nutrition. En conclusion, cette recherche a identifié plusieurs pistes d’intervention pour améliorer la qualité des soins obstétricaux en Afrique de l’Ouest.

L'effet de l'entrainement avec le ballon d'exercice pendant la grossesse sur l'accouchement.

Résumé Introduction : L’entrainement avec le ballon d’exercice pendant la grossesse a des effets positifs sur le déroulement de l’accouchement. Le but de l’étude était d’identifier si une association existe entre le volume d’entrainement avec le ballon d’exercice durant la grossesse en milieu naturel sur l’issue du déroulement de l’accouchement, soit la durée des phases 1 (dilatation/phase active) et 2 (expulsion), ainsi que l’usage de la péridurale et de la césarienne. Méthode: Cette étude quasi-expérimentale a été menée auprès d'un échantillon de convenance composée de 32 femmes enceintes qui ont pris part entre un et 28 cours d'exercice supervisé durant la grossesse (programme Ballon Forme), avec la possibilité d'effectuer des exercices supplémentaires à la maison avec le ballon d’exercice. Un questionnaire et un journal de bord ont été remplis par les participantes, avec l'aide d'une infirmière de l’hôpital pour les données médicales. Résultats: Un volume d’entrainement élevé, incluant l’entraînement sous forme de cours et à domicile, a été significativement associé à une durée plus courte d’accouchement, que ce soit pour le temps total de l’accouchement (r = -0,408, p = 0,031) ou pour les deux phases spécifiques de l’accouchement [la phase 1: r = -0,372 ; p = 0,043 et la phase 2: r = -0,415, p = 0,028]. Un volume d’entrainement élevé a aussi été lié à une réduction de la deuxième phase chez les femmes qui donnaient naissance pour la première fois. La durée totale des exercices exécutés lors des cours a été significativement associée à cette réduction comparativement aux exercices à la maison. Aucun effet indésirable n'a été observé avec le volume d’entrainement élevé sur les paramètres de l’accouchement et la santé du bébé (Apgar et poids du bébé à la naissance). En fait, un nombre très faible de césarienne (6%), de recours à la péridurale (47%) et d'extraction instrumentale (forceps ou ventouse: 13%) a été observé dans notre échantillon de femmes. Conclusion: La pratique du ballon d’exercice est une avenue prometteuse pour les femmes enceintes et un niveau élevé d’entraînement est associé à un accouchement plus rapide et sans complications pour le bébé. L’implantation de ce programme pourrait éventuellement contribuer à réduire considérablement les coûts de santé au Québec en favorisant l’accouchement naturel. Des interventions et des recherches ultérieures devront considérer et examiner cette modalité spécifique d’entrainement pour les femmes enceintes.

Le dispositif institutionnel et la relation thérapeutique en salle d'accouchement : entre le risque, le savoir hégémonique et les rapports de pouvoir.

Ce mémoire vise à établir la complexité de la relation thérapeutique entre l’infirmière et le couple en salle d’accouchement. Sachant que la relation thérapeutique est essentielle à la réussite du processus de soins, sa conceptualisation demeure primordiale pour une meilleure compréhension de son impact et pour mener à bien les soins. Cette recherche ethnographique a voulu documenter les relations des infirmières avec des couples en salle d’accouchement dans un hôpital de l’île de Montréal. Ce mémoire aborde un thème central de l’anthropologie : les relations humaines. La question clef de ce mémoire questionne les facteurs qui entravent et qui favorisent la relation thérapeutique entre l’infirmière et le couple en salle d’accouchement. Cette recherche démontre des lacunes théoriques qui technicisent la relation thérapeutique et indique que la notion du risque, les normes institutionnelles, l’hégémonie du savoir obstétrical et le pouvoir médical sont des facteurs qui semblent avoir une grande influence dans la relation thérapeutique.
