Survey on maternal satisfaction in receiving spinal anesthesia for Cesarean section / A quantitative descriptive and cross-sectional study was conducted. The purpose of the study was to evaluate the maternal satisfaction after the experience of spinal anaesthesia for Caesarean section in one public hospital of Gauteng Province in South Africa. Data were collected by administering a questionnaire which included the demographic profile and satisfaction score in terms of perioperative elements to 82 women in their postoperative period. Analysis of data was performed by The Statistical Package for the Social Sciences (SPSS) version 13 and Excel 2010 was used for tabular and graphical illustrations. The findings revealed that the majority of women studied were black (95,1%), not married (73,2%) and unemployed (64,6%). The levels of maternal satisfaction in terms of intraoperative, postoperative and other perioperative elements were high, at 94,4%, 90,3% and 85,4% respectively. The lowest percentage (76,8%) was found for the maternal satisfaction about the preoperative explanation. The overall level of maternal satisfaction in this study was 86,7%. The majority of women (82,9%) would opt for spinal anaesthesia in future, while 6,1% would not accept it and 11,0% were not sure if they would opt for it or not. / Health Studies / M. A.

Abstrakt Bakgrund: Forskning visar att generell anestesi kan bidra till kognitiv dysfunktion postoperativt. En alltför djup anestesi och/eller en lång duration av anestesi är två faktorer som kan inverka på kognitionen med besvär såsom minnesproblem och koncentrationssvårigheter. Anestesisjuksköterskans roll är att individanpassa anestesin för att inte orsaka för djup anestesi och därmed har det blivit alltmer vanligt att monitorera anestesidjupet för att minska på onödigt lidande för patienten. Syfte: Syftet är att kartlägga anestesidjup och anestesiduration  hos patienter med självskattad  kognitiv svikt efter elektiv ortopedisk operation. Metod: För att kartlägga detta valdes en retrospektiv observationsstudie med tvärsnittsdesign med insamlad data från kvalitetsregister. Resultat: Av 920 patienter var det 116 patienter som uppgav kognitiv dysfunktion dag 1 postoperativt och upp till över 16 dagar postoperativt med  ett genomsnittsvärde på 37,7 i entropy och 104,4 minuter i anestesiduration. Slutsats: Desto längre duration av anestesin och ju djupare anestesi desto mer kognitiv påverkan postoperativt. Anestesidjupsmonitorering bör användas mer frekvent och önskvärt är att bedöma kognition preoperativt med ett mätinstrument för att kunna se om skillnad finns postoperativt.

Au sein d’un établissement hospitalier, le bloc opératoire représente un des secteurs les plus emblématiques et les plus coûteux. Le fonctionnement du bloc opératoire est orchestré par un programme opératoire qui consiste à construire un planning prévisionnel des interventions chirurgicales à réaliser pendant un horizon donné. La littérature abondante sur le sujet est unanime sur le fait que la construction du programme opératoire est une tâche complexe, car il s’agit non seulement de planifier et d’ordonnancer les interventions, mais aussi de satisfaire des exigences souvent antagonistes. Ce projet est le fruit d’une collaboration entre la Communauté d’Agglomération de Sarreguemines Confluences et la Région Lorraine, des membres du secteur hospitalier (Hôpital Robert Pax de Sarreguemines) et l’équipe Gestion Industrielle et Logistique (GIL) du Laboratoire de Génie Industriel, de Production et de Maintenance (LGIPM). L’objectif de cette recherche est d’apporter une aide aux gestionnaires du bloc opératoire, qui ont besoin de plus en plus des méthodes et des outils d’aide à la décision en vue d’optimiser leur fonctionnement. Pour répondre à ce besoin nous nous intéressons dans la première partie de cette thèse à la gestion des opérations électives en prenant en compte différentes contraintes et en particulier la disponibilité des chirurgiens. Nous nous plaçons dans le contexte d’une stratégie « open scheduling » et nous proposons deux modèles mathématiques permettant d’élaborer le programme opératoire. La complexité des modèles mathématiques et leur explosion combinatoire rendent difficile la recherche de l’optimum pour des tailles réalistes. Ceci nous a donc amené à proposer une heuristique constructive utilisant le modèle proposé et permettant d’obtenir des solutions là où la méthode exacte ne nous le permettait pas. Dans la seconde partie de cette thèse, nous considérons l’intégralité du processus opératoire (brancardage vers le bloc opératoire, préparation et anesthésie, acte chirurgicale et réveil). Nous modélisons ce processus comme un flow shop hybride à 4 étages avec contrainte de blocage de type RSb, et nous le résolvons à l’aide d’un algorithme génétique dont l’objectif est de synchroniser toutes les ressources nécessaires, en respectant au mieux le programme opératoire prévisionnel. Outre les opérations électives, nous nous intéressons dans la dernière partie aux opérations urgentes. Nous proposons un outil d’aide à la décision pour la gestion des opérations urgentes. En prenant en considération la pathologie et la gravité de l’état du patient, nous distinguons principalement 3 degrés d’urgences et proposons pour chacune un algorithme permettant d’intégrer en temps réel ces opérations dans le programme prévisionnel, tout en minimisant différents critères (temps d’attente avant affectation, heures supplémentaires, décalage par rapport aux anciennes dates de débuts) / The operating theater is one of the most critical and expensive hospital resources. Indeed, a high percentage of hospital admissions are due to surgical interventions. Rising expenditures spur health care organizations to organize their processes more efficiently and effectively. This thesis is supported by the urban community of Sarreguemines-France and the region of Lorraine-France, and is carried out in collaboration with the Centre Hospitalier de Sarreguemines - Hôpital Robert Pax. In the first part of this work, we propose two mathematical programming models to help operating theater managers in developing an optimal operating rooms scheduling. We also propose a constructive heuristic to obtain near optimal results for realistic sizes of the problem. In the second part of our work, the whole scheduling process is modeled as a hybrid four-stage flow shop problem with RSb blocking constraint, and is solved by a genetic algorithm. The objective is to synchronize all the needed resources around the optimal daily schedule obtained with the proposed mathematical model. The last part of our work is dedicated to non-elective surgeries. We propose a decision support tool, guiding the operating room manager, to handle this unpredictable flow of patients. Non-elective patients are classified according to their medical priority. The main contribution of the proposed decision support tool is to provide online assignment strategies to treat each non elective patient category. Proposed assignments are riskless on patient’s health. According to non-elective surgery classes, the proposed adjusted schedule minimizes different criteria such as patient’s waiting time, deviation from the firstly scheduled starting time of a surgery and the amount of resulting overtime

Over the last few years, policies have been introduced in the UK which aim to improve organ transplantation rates by changing the way that potential organ donors are treated before death. Patients incapacitated due to catastrophic brain injury may now undergo ante-mortem donor optimisation procedures to facilitate deceased organ donation. As I identify in this thesis, the most significant ethical and legal problem with these policies is that they are not based on what the patient would have chosen for themselves in the specific circumstances. The policies identify and treat patients meeting certain clinical criteria as a group rather than the individuals, with their own viewpoints, that the law on best interests requires. They equate registration on the Organ Donation Register with ante-mortem donor optimisation procedures being in their best interests, despite registrants having neither been informed about nor given consent to ante-mortem interventions. The overarching claim I make in this thesis is that a system of specific advance consent is needed to provide a clear and unequivocal legal justification for ante-mortem donor optimisation procedures. The ethical foundation for this claim is autonomy, and this is the central theme running through all six chapters. I argue that autonomy should be incorporated into donor optimisation policy to promote the dignity and integrity of potential organ donors and to safeguard trust in the organ donation programme. I argue that a system of specific advance consent is needed as part of the duty of care owed to registrants on the Organ Donor Register and to facilitate the determination of the best interests of the potential organ donor. I argue that the state has not established the necessity of the current policy of non-consensual donor optimisation procedures and that they are under an ethical and legal obligation to introduce an autonomy-based framework for ante-mortem interventions to facilitate organ donation.

In the Spanish legal system, the workplace employee representation but may have certain similarities with the political representation (regulatory origin, not voluntary for the principal, democratic legitimacy) poses a specificity both the subjective perspective, to be circumscribed workers who make up the constituency, as a material arises as to represent the professional interests shared by a community of individuals united by an identical legal relationship derived from belonging to the same company. Its uniqueness is that this function can be assumed, concurrently, for two types: some representatives of elective basis; others, union base. This legal decision set a pluralistic model of subjects, but strongly interconnected functional dimension, due to differing legal natures. / En el ordenamiento jurídico español, el modelo de representación de los trabajadores en la empresa aunque pueda tener ciertas similitudes con la representación política (origen normativo y no voluntario para el representado, legitimidad democrática) plantea una especificidad tanto desde la perspectiva subjetiva, al quedar circunscrita a los trabajadores que conforman la circunscripción electoral, como material pues surge para la representación de los intereses profesionales compartidos por una colectividad de sujetos unidos por una idéntica vinculación jurídica, derivada de la pertenencia a la misma plantilla. Su singularidad es que esta función puede ser asumida, de manera concurrente, por dos tipos de sujetos: unos representantes de base electiva; otros, de base sindical, configurando con esta decisión legal un modelo pluralista de sujetos que, aunque fuertemente interconectado en su dimensión funcional, obedece a naturalezas jurídicas distintas.

Héritières des années 1970 les communautés intentionnelles ont pour objectif de remettre en cause les pratiques et liens sociaux propres à la société contemporaine. Par l’association du travail et de la vie domestique elles forment un type d’organisation sociale tournée vers le vivre ensemble et le travail du commun. Cette thèse démontre à partir du cadre théorique de la résistance ordinaire, que les communautés intentionnelles mettent en pratique une manière d’être au monde qui leur est spécifique. Par le retour à la terre et le détour par la nature, elles inscrivent leur action dans une temporalité et une spatialité nourries d’une projection utopique puisant ses sources dans les représentations d’un passé mythifié. Celui-ci sert la mise en action dans le présent de ce monde et l’expérimentation d’un monde à faire advenir. Ces communautés développent, des visions et un agir guidés par ce que je propose d’appeler une rétrospection utopique. Ce faisant, elles investissent des espaces publics interstitiels et oppositionnels en juxtaposant des imaginaires et des pratiques qui font correspondre à trois logiques sociales (le mythe, le retour, l’utopie) trois registres d’historicité (conservation, rétrospection, progression). Elles organisent le ralentissement de la machine technobureaucratique et capitaliste et convoquent les racines agraires des sociétés antérieures pour préfigurer l’avènement d’une société nouvelle, agraire et politique. / Recipients of the 1970’s legacy, intentional communities aim at reconsidering the practices and social relations specific to contemporary society. Through the association of work and domestic life they form a kind of social organization turned towards «living together » and « working the common ». Using the theoretical framework of common resistance as a basis, this thesis demonstrates that intentional communities put into practice a peculiar manner of being-in-the-world. By way of a return to the land and of a detour via nature, their action is inscribed in a temporality and a spatiality fueled by utopian projection, which draws on representations of a mythologized past. That past serves the present-time actualisation of this world, and the experimentation of a world-to-be-brought-about. These communities develop visions and ways of doing guided by what I suggest we call utopian retrospection. In doing so, they invest intersitial and oppositional public spaces by juxtaposing imaginaries and practices that correlate three social logics (myth, return, utopia) with three registers of historicity (conservation, retrospection, progression). They organise the slowing down of the techno-bureaucratic and capitalistic machine and summon the agrarian roots of earlier societies to prefigure the advent of a new society, both agrarian and political.

Background: Standardized staging procedures and presentation of oral squamous cell carcinoma (OSCC) patients in multidisciplinary tumor boards (MDTB) before treatment and utilization of elective neck dissection (ND) are expected to improve the outcome, especially in local advanced LAOSCC (UICC stages III–IVB). As standardized diagnostics but also increased heterogeneity in treatment applied so far have not been demonstrated to improve outcome in LAOSCC, a retrospective study was initiated. Methods: As MDTB was introduced into clinical routine in 2007, 316 LAOSCC patients treated during 1991-2017 in our hospital were stratified into cohort 1 treated before (n=104) and cohort 2 since 2007 (n=212). Clinical characteristics, diagnostic procedures and treatment modality of patients were compared using Chi-square tests and outcome analyzed applying Kaplan-Meier plots and log-rank tests as well as Cox proportional hazard regression. Propensity scores (PS) were used to elucidate predictors for impaired distant metastasis-free survival (DMFS) in PS-matched patients. Results: Most patient characteristics and treatment modalities applied showed insignificant alteration. Surgical treatment included significantly more often resection of the primary tumor plus neck dissection, tracheostomy and percutaneous endoscopic gastrostomy tube use. Cisplatin-based chemo-radiotherapy was the most frequent. Only insignificant improved disease- (DFS), progression- (PFS) and event-free (EFS) as well as tumor-specific (TSS) and overall survival (OS) were found after 2006 as local (LC) and locoregional control (LRC) were significantly improved but DMFS significantly impaired. Cox regression applied to PS-matched patients elucidated N3, belonging to cohort 2 and cisplatin-based chemo-radiotherapy as independent predictors for shortened DMFS. The along chemo-radiotherapy increased dexamethasone use in cohort 2 correlates with increased DM. Conclusions: Despite standardized diagnostic procedures, decision-making considering clear indications and improved therapy algorithms leading to improved LC and LRC, shortened DMFS hypothetically linked to increased dexamethasone use had a detrimental effect on TSS and OS.

Introduktion: Enhanced Recovery After Surgery (ERAS) är ett evidensbaserat vårdprogram inom elektiv kirurgi. Studier har visat att följsamhet över 75% till ERAS-programmet har ett förbättrat utfall efter kirurgi i form av mindre komplikationer, kortare length of stay (LOS) och förbättrad återhämtning. Patientens postoperativa återhämtning efter elektiv ändtarmskirurgi med ERAS-programmet kan vara utmanande på grund av illamående, smärta, intravenösa vätskor, mobilisering och typ av kirurgisk metod, vilket kan leda till att patienten drabbas av komplikationer som förlänger LOS. Intensivvårdssjuksköterskor har en viktig roll i den postoperativa fasen för patienter som vårdas enligt ERAS-programmet relaterat till dennes arbetsområden.Syfte: Att studera följsamheten, kortsiktigt resultat och den postoperativa återhämtningen för patienterna som genomgått elektiv ändtarmskirurgi enligt ett ERAS-program relaterat till intensivvårdssjuksköterskans arbetsområden.Metod: Denna studie är en kvantitativ kohortstudie med retrospektiv ansats. Datainsamling genomfördes med hjälp av ERAS Interactive Audit System databas (EIAS), där 393 patienter mötte inklusion- och exklusionskriterierna. Av dom var 231 patienter opererade med öppen kirurgi och 162 patienter med robotkirurgi. Resultat: I den postoperativa fasen var följsamheten till ERAS-programmet 43.5% för öppen kirurgi och 57.7% för robotkirurgi. Det kortsiktiga resultatet, antalet LOS och komplikationer, visade signifikant skillnad mellan de kirurgiska metoderna. Antalet LOS och komplikationer var högre för öppen kirurgi jämfört med robotkirurgi. I den postoperativa återhämtningen för patienterna kunde det observeras flera signifikanta skillnader i utfallet mellan de kirurgiska metoderna. Patienter som opererats med robotkirurgi hade i flertalet områden bättre utfall jämfört med de som opererats med öppen kirurgi.Slutsats: Resultatet i denna studie visade att den totala följsamheten (pre-, intra- och postoperativ följsamhet) för patienter som följer ett ERAS-programmet efter ändtarmskirurgi inte kom upp i den rekommenderade nivån >75% följsamhet. Trots att patienter följde ett standardiserat vårdprogram som ERAS visade det att uppnå en hög följsamhet har sina utmaningar i form av postoperativ återhämtning. Intensivvårdssjuksköterskan har arbetsområden som kan förbättras för att hjälpa patienterna uppnå målen med ERASprogrammet och därmed säkerställa evidensen för ett bättre utfall i form av snabbare återhämtning, minskade komplikationer och kortare LOS.

Entretanto, no Brasil há poucos estudos sobre filas de espera nos serviços de saúde. Este é um estudo de caso que pretende contribuir acrescentando métrica nessa discussão e fundamentando-a em torno da viabilidade econômico-financeira das decisões em saúde e da regulação, de modo mais amplo. Partindo do contexto de um hospital municipal da zona sul da cidade de São Paulo, analisamos dois cenários diferentes, a demanda proveniente da atenção básica para consulta com especialista, que nem sempre termina na indicação de cirurgia, e as filas de espera internas ao hospital para cirurgia ginecológica, de pacientes já avaliadas e com cirurgia indicada, aguardando seu agendamento. Da análise desses dados, traçamos um novo modelo de gerenciamento da fila de espera para cirurgia ginecológica eletiva nesse hospital. Nossa proposta não tem o objetivo de atingir espera zero. Tampouco é fundamentada em estratégia única. Nossa principal conclusão é que a estratégia mais eficiente para o gerenciamento das filas de espera envolve o fortalecimento das ações de integração com a rede de atenção. No Sistema Único de Saúde, o olhar de linha de cuidado, pode viabilizar efetivamente a entrega de maior valor na assistência prestada e pode ser feita através de iniciativas locais. / Waiting lists are a chronic problem in countries that opted for universal health systems. However, there are few studies on waiting lists in health services in Brazil. This case study aims to contribute by adding metrics to this discussion and grounding it around the economic-financial viability of health care decisions and access regulation in a broader way. Starting from the context of a municipal hospital in the south of the city of São Paulo, we analyzed two different scenarios: the demand for primary care for consultation with a specialist, which does not always end with the recommendation of surgery, and inpatient waiting lists, which have patients that were already evaluated and are waiting for the surgery. From this data analysis, we draw a new management model of gynaecologic elective surgery waiting list in this hospital. Our proposal does not aim to achieve zero wait, nor is it based on a single strategy. Our main conclusion is that the most efficient strategy for the waiting lists management involves the strengthening of health care networks’ integration actions. In the Unified Health System it can effectively enable the delivery of greater value in the assistance provided and can be done through local initiatives.

<p>Akutno bubrežno o&scaron;tećenje je česta i ozbiljna komplikacija nakon hirur&scaron;ke rekonstrukcije abdominalne aorte. Ona produžuje, poskupljuje bolničko lečenje i povećava morbiditet i mortalitet bolesnika. &Scaron;to ranije prepoznavanje bolesnika koji su pod povi&scaron;enim rizikom uz pomoć prediktivnih faktora, kao i identifikovanje akutnog bubrežnog o&scaron;tećenja od velikog je značaja za pravovremeno započinjanje preventivnih i terapijskih mera i smanjenje mortaliteta ovih bolesnika. Cilj istraživanja: Utvrditi incidencu akutnog bubrežnog o&scaron;tećenja, najznačajnije preoperativne i intraoperativne prediktivne faktore za nastanak akutnog bubrežnog o&scaron;tećenja i utvrditi da li serumski cistatin C ranije i preciznije ukazuje na akutno bubrežno o&scaron;tećenje u odnosu na serumski kreatinin 72 sata nakon elektivnih operacija na infrarenalnom segmentu aorte. Metodologija: Na Klinici za anesteziju, intenzivnu terapiju i terapiju bola i Klinici za vaskularnu i transplantacionu hirurgiju Kliničkog centra Vojvodine sprovedeno je prospektivno opservaciono istraživanje u trajanju od 18 meseci, od oktobra 2017. do aprila 2019. godine. U istraživanje je uključeno 140 pacijenata koji su podvrgnuti elektivnom operativnom zahvatu na infrarenalnom segmentu aorte. Preoperativni i intraoperativni potencijalni prediktivni faktori identifikovani su iz medicinske dokumentacije: istorije bolesti, protokoli anestezije, dnevne terapijske liste, liste vitalnih parametara i liste laboratorijskih parametara. Nastanak ABO je potvrđivan pomoću AKIN klasifikacionog sistema. Tokom postoperativnog perioda lečenja od 72 sata obraćana je pažnja na vreme i stepen nastanka ABO. Za statističku obradu podataka kori&scaron;ćen je program SPSS, verzija 21 (IBM SPSS, Čikago, Ilinois). Rezultati su predstavljeni tabelarno i grafički, a statistički značajnim su se smatrale vrednosti nivoa značajnosti p&lt;0,05. Podaci su obrađivani standardnim statističkim testovima. Za dobijanje modela predikcije primenjena je multivarijantna logistička regresija. Rezultati: Incidenca akutnog bubrežnog o&scaron;tećenja nakon elektivnih operacija na infrarenalnom segmentu aorte na Klinici za anesteziju, intenzivnu terapiju i terapiju bola i Klinici za vaskularnu i transplantacionu hirurgiju Kliničkog centra Vojvodine iznosi 28,56%. Prema ROC analizi granična vrednost koncentracije cistatina C od 1,14 mg/l ima najvi&scaron;u senzitivnost (82,5%), i specifičnost (76%) u diferenciranju bolesnika koji će dobiti akutno bubrežno o&scaron;tećenje. Kompletan model predikcije ABO nakon elektivnih operacija na infrarenalnom segmentu aorte sadrži sledeće faktore: prisustvo hronične bubrežne slabosti, preoperativna serumska koncentracija cistatina C &gt;1,14 mg/l, primena koloida u volumenu &gt;500 ml u toku operacije, ukupni volumen nadoknade u intraoperativnom periodu &gt;59 ml/kg. Zaključak: Incidenca akutnog bubrežnog o&scaron;tećenja nakon elektivnih operacija na infrarenalnom segmentu aorte na Klinici za anesteziju, intenzivnu terapiju i terapiju bola i Klinici za vaskularnu i transplantacionu hirurgiju Kliničkog centra Vojvodine je ne&scaron;to vi&scaron;a u odnosu na literaturne podatke. Cistatin C je bolji prediktor i pokazatelj akutnog bubrežnog o&scaron;tećenja u odnosu na kreatinin. Bolesnici koji imaju hroničnu bubrežnu slabost, preoperativni nivo cistatina C&gt;1,14 mg/l, koji tokom operacije dobiju preko 500 ml koloidnih rastvora, i ukupni volumen nadoknade &gt;59 ml/kg imaju veću &scaron;ansu da dobiju akutno o&scaron;tećenje bubrega u postoperativnom periodu.</p> / <p>Acute kidney injury is frequent and serious complication after aortic surgery which increases length of hospital stay, costs, morbidity and mortality. Earlier recognition of patients at risk by predictive factors and identification of acute kidney injury could have important role on right timing of preventive and therapeutic measures and lower mortality of these patients. Aims: to investigate the incidence of acute kidney injury, the most important preoperative and intraoperative predictive factors for acute kidney injury, and check whether cystatin C indicates acute kidney injury earlier and more accurately than creatinine 72 hours after elective infrarenal aortic surgery. Methodology: This prospective observational study was performed at Clinic of Anesthesia, Intensive Care and Pain Therapy and Clinic of Vascular and Transplantation Surgery, Clinical Centre of Vojvodina, during the period of 18 months, from October 2017 till April 2019. It includes 140 adult patient who underwent elective infrarenal aortic surgery. Potential predictive factors were identified out of medical records such as: patient history, anesthesia lists, daily therapeutic lists, vital parameters and laboratory values lists. The occurrence of acute kidney injury was noted according to AKIN criteria. IBM SPSS version 21 (Chicago, Illinois) was used for statistical analysis. The results were presented in tables and graphs, statistical significance was set at p value of less than 0,05. Standard statistical tests were applied. Multivariate logistic regression model was used for potential predictive factors. Results: The incidence of acute kidney injury at Clinic of Anesthesia, Intensive Care and Pain Therapy and Clinic of Vascular and Transplantation Surgery, Clinical Centre of Vojvodina, was 28,56%. The cut off value of cystatin C serum concentration of 1,14 mg/l has the highest sensitivity (82,5%), and specificity (76%) in the differentiation of patients who will develop acute kidney injury. The final model for predicting acute kidney injury in patients who underwent elective infrarenal aortic surgery contains the following variables: presence of chronic kidney failure, preoperative serum concentration of cystatin C&gt;1,14 mg/l, application of colloid solutions in volume&gt;500 ml during the operation and total intravascular fluid replacement volume&gt;59 ml/kg in intraoperative period. Conclusion: The incidence of acute kidney injury at Clinic of Anesthesia, Intensive Care and Pain Therapy and Clinic of Vascular and Transplantation Surgery, Clinical Centre of Vojvodina, is somewhat higher comparing to world literature data. Patients who are more likely to develop acute kidney injury have: chronic kidney failure, preoperative serum concentration of cystatin C&gt;1,14 mg/l and get colloid solutions in volume&gt;500 ml and total intravascular fluid replacement volume&gt;59 ml/kg during intraoperative period.</p>
