No. of bitstreams: 1 Keila Calil.pdf: 845273 bytes, checksum: 57f8ea9c395904645b8c8cc412ae204c (MD5) Previous issue date: 2014 / Mestrado Profissional em Enfermagem Assistencial / Problema: O objeto deste estudo apresenta-se pelas evidências científicas para a prevenção de Infecção Primária de Corrente Sanguínea (IPCS) em pacientes em uso do Cateter Venoso Central (CVC). A IPCS representa um dos principais problemas da assistência à saúde, com consequente impacto na morbidade e mortalidade dos pacientes, principalmente, daqueles que em decorrência da gravidade de sua doença, necessitam de um CVC. Muito se tem discutido, recentemente, acerca da segurança do paciente e reavaliar as práticas assistenciais prestadas com a utilização de um conjunto de boas práticas denominado "bundles", é uma orientação para redução dessas infecções. Objetivos: Construir um bundle para prevenção de Infecção Primária de Corrente Sanguínea (IPCS) no manuseio do Cateter Venoso Central (CVC). Descrever as evidências científicas para prevenção de IPCS em pacientes em uso do CVC estabelecendo padrões para as ações de enfermagem referente à prevenção dessas infecções. Elaborar critérios de avaliação das ações de enfermagem com vistas à prevenção de IPCS em pacientes em uso do CVC. Método: Pesquisa Baseada em Evidência (PBE) com a utilização de diretrizes nacional e internacional. Resultados e Discussão: Em virtude da necessidade de prevenção e controle das IRAS (Infecções Relacionadas à Assistência à Saúde), podem-se considerar as diretrizes que abordam este tema como guia para a prática de um cuidado seguro para os pacientes uma vez que estas concentram na descrição das ações de prevenção o melhor nível de evidência disponível e de forma atualizada. Especificamente sobre a IPCS em pacientes em uso do CVC, salienta-se a importância das ações de prevenção serem praticadas em conjunto e ao mesmo tempo serem passíveis de avaliação com o objetivo de repensar o cuidado dispensado aos pacientes e educar a equipe de enfermagem para melhores práticas assistenciais. Dentro deste contexto a construção do bundle para manuseio do CVC apresenta-se como objeto e para construí-lo foram examinadas as diretrizes para prevenção de IPCS em pacientes em uso do CVC e redefinidas as ações de enfermagem para uma adequação à realidade que se pretende intervir. Por conseguinte, foram estabelecidos os padrões de cuidado para que assim fossem elaborados os critérios de avaliação para as ações de enfermagem que compõem o bundle. É possível, dessa maneira, visualizar o bundle como um instrumento para orientação, avaliação e melhoria do cuidado referente às ações como a higienização das mãos antes e após o manuseio do CVC e do sistema de infusão, uso de luvas não estéreis e desinfecção das conexões antes de serem acessadas, troca do sistema de infusão no tempo adequado com identificação da data, troca correta do curativo do sítio de inserção do CVC e documentação da avaliação diária do sítio de inserção do CVC. Considerações Finais: Pode-se afirmar que a melhor evidência científica para atuar na prevenção da IPCS em pacientes em uso do CVC se encontram nas diretrizes do Centers for Disease Control and Prevention (CDC). Entretanto, não é possível desconsiderar as diretrizes da Agência Nacional de Vigilância Sanitária (ANVISA) uma vez que dados da realidade do Brasil junto à realidade de um serviço específico são fatores determinantes para o sucesso de uma estratégia de melhoria. Contribuir para que os Enfermeiros e Técnicos de Enfermagem que atuam em UTI de adultos permaneçam familiarizados com as evidências científicas para prevenção de IPCS em pacientes em uso do CVC e se comprometam em executar estas ações é uma das formas de envolver os recursos humanos no propósito de modificar uma realidade e contribuir para uma assistência de enfermagem mais uniforme no que diz respeito à teoria e prática. Significa entender a importância da enfermagem para a prevenção e controle de infecções e incentivar a busca por novos conhecimentos. Entende-se que, mostrar para esses profissionais como se apresenta a prática do cuidado da equipe de enfermagem é um aspecto decisivo para repensar a prática e encontrar um caminho em busca da segurança do paciente. / Problem: The object of this study presents the scientific evidences for the prevention of primary bloodstream infections in patients using central venous catheter (CVC). The IPCS is a major problem in health care, with consequent impact on morbidity and mortality of patients, mainly for those needs a CVC due the severity of their condition. Recently, much has been discussed about the safety of the patient and to reassess the care practices provided using a set of best practices called "bundles" is an orientation to reducing these infections. Aims: Build a Bundle for prevention of IPCS in handling CVC. Describe the scientific evidences for the prevention of IPCS in patients using CVC establishing standards for nursing actions related to the prevention of these infections. Develop evaluation criteria of nursing actions aimed at preventing IPCS in patients using CVC. Method: Evidence-Based Research (EBR) with the use of national and international guidelines. Results and Discussion: Because of the need for prevention and control of Prevent Health Care-Associated Infections (HAIs), the guidelines that address this issue may be considered as a guide to safe care practice for patients, since on description of prevention they focus the best level of evidence available and updated form. Specifically on the IPCS in patients using CVC emphasizes the importance of prevention being practiced together while being assessable in order to rethink the care given to patients and educating nursing staff for best assistance practices. Within this context, the construction of the bundle for handling the CVC presents itself as an object and to build it were examined IPCS guidelines for prevention in patients using CVC and nursing actions were redefined for adaptation to the reality that if you want to intervene. Subsequently were established the patterns of care for after develop evaluation criteria for nursing actions that make up the bundle. Thus, it’s possible to view the bundle as a tool for guidance, evaluation and improvement of care relating to actions such as washing hands before and after handling the CVC and the infusion system, use of non-sterile gloves and disinfecting of the connections before to access them, exchange of the infusion system at the appropriate time with identify the date, correctly replacement of the bandage of the insertion site of CVC and documentation of the daily assessment of the site of insertion of the CVC. Final Thoughts: It can be argued that the best scientific evidences for the early prevention of IPCS in patients using CVC are the guidelines of the Centers for Disease Control and Prevention (CDC). However, it is not possible to disregard the guidelines of the National Health Surveillance Agency (ANVISA, in Portuguese), since data from the reality of Brazil and the reality of a particular service are crucial to the success of an improvement strategy. Contribute to the nurses and nursing technicians who work in the adult ICU remain familiar with the scientific evidence for the prevention of IPCS in patients using CVC and commit themselves to perform these actions is one way to involve human resources in order to modifying a reality and contribute to a more uniform nursing assistance regarding the theory and practice. Means understanding the importance of nursing for the prevention and control of infections and encourage the search for new knowledge. It is understood that, to show for these professionals as the care practice of the nursing staff presents is a critical aspect to rethink the practice and find a path in search of the patient safety.

Le rôle des facteurs physiologiques et neuromécaniques dans l’évolution des douleurs lombo-pelviennes chez la femme enceinte : prévention, évaluation et traitement

Daneau, Catherine 10 1900 (has links)
La grossesse est une période importante dans la vie d’une femme. Celle-ci va subir différents changements (hormonaux et cliniques) et différentes adaptations (neuromécaniques) qui peuvent contribuer au développement de douleurs dans les régions lombaire et pelvienne, aussi appelées douleurs lombo-pelviennes. Cette thèse vise à déterminer quelle est la contribution des facteurs hormonaux, neuromécaniques et cliniques qui contribuent au développement et à l'évolution des douleurs lombo-pelviennes chez la femme enceinte pour éventuellement déterminer quelles sont les approches à adopter en matière de prise en charge de ces douleurs. À l’aide de quatre études (revue intégrative de la littérature, revue narrative, étude de cohorte et étude de faisabilité contrôlée et randomisée), cette thèse a permis de comparer la littérature actuelle avec de nouvelles études et de mettre en lumière les manques encore présents en lien avec ce sujet. La revue intégrative de la littérature a permis de constater que la relaxine (l’hormone la plus étudiée en comparaison à l’oestrogène et la progestérone) ne semble pas être associée au développement ni à l’évolution des douleurs lombo-pelviennes chez les femmes enceintes. La revue narrative présente les changements hormonaux et biomécaniques ainsi que les adaptations neuromusculaires liées à la grossesse qui pourraient jouer un rôle dans le développement des douleurs lombo-pelviennes pendant la grossesse. L’étude de cohorte a montré une augmentation de l'intensité des douleurs lombo-pelviennes et de l'incapacité physique, une augmentation du risque de mauvais pronostic pour la douleur ainsi qu’une diminution du catastrophisme lié à la douleur au fil de la grossesse. Les résultats ont aussi montré une corrélation entre l'incapacité physique et les niveaux d'oestrogènes (premier-deuxième trimestre), ainsi qu'une corrélation entre les niveaux d'oestrogènes et l'intensité de la douleur diurne (deuxième-troisième trimestre). L’étude de faisabilité contrôlée et randomisée a été réalisée auprès de 32 femmes enceintes recrutées sur une période de 14 mois. Parmi elles, 26 (11 dans le groupe d'intervention et 15 dans le groupe contrôle) ont participé à la visite post-intervention (taux de rétention de 81,3 %). Le taux d'observance était similaire pour les séances d'exercices supervisées et non supervisées, bien que l'acceptabilité fût meilleure pour les séances supervisées par rapport aux séances non supervisées. À la rencontre pré-intervention, les caractéristiques des participantes étaient similaires entre les deux groupes, sauf pour le niveau d'éducation (plus élevé dans le groupe contrôle). Les résultats préliminaires n'ont montré aucune différence significative dans la fréquence, l'intensité et l'incapacité physique associées aux DLP entre les groupes, bien que des tendances prometteuses aient été observées. Cette thèse examine les changements hormonaux, cliniques, biomécaniques et les adaptations neuromusculaires chez les femmes enceintes souffrant de douleurs lombo-pelviennes. Les résultats montrent qu’un programme d'exercices de contrôle moteur est sûr et faisable avec quelques ajustements, mais que la stabilité de la région lombo-pelvienne demeure complexe et incertaine en raison des variations hormonales et des adaptations neuromécaniques pendant la grossesse. Bien que l'efficacité de l'intervention n'ait pas été statistiquement démontrée, nos résultats ont montré la faisabilité d’une éventuelle étude contrôlée et randomisée à plus grande échelle. Cette thèse identifie également des aspects à considérer pour les futures études visant à améliorer la prise en charge des femmes enceintes souffrant de douleurs lombo-pelviennes pendant la grossesse. / Pregnancy is an important period in a woman's life. Pregnant women will undergo different changes (hormonal and clinical) and adaptations (neuromechanical) that can contribute to the development of pain in the lumbar and pelvic region, also known as lumbopelvic pain. This thesis aims to determine the contribution of hormonal, neuromechanical, and clinical factors that contribute to the development and evolution of lumbopelvic pain in pregnant women, to eventually determine which approaches should be adopted in terms of managing these pains. Through four studies (an integrative literature review, a narrative review, a cohort study, and a controlled and randomized feasibility study), it was possible to compare current literature with new studies and highlight the gaps still present in this field. The integrative literature review showed that relaxin (the hormone most studied in comparison to estrogen and progesterone) does not seem to be associated with the development or evolution of lumbopelvic pain in pregnant women. The narrative review presents the hormonal and biomechanical changes as well as the neuromuscular adaptations related to pregnancy that could play a role in the development of lumbopelvic pain during pregnancy. The cohort study showed an increase in the intensity of lumbopelvic pain and disability, an increase in the risk of poor prognosis for pain, as well as a decrease in pain catastrophizing over the course of pregnancy. The results also showed a correlation between disability and estrogen levels (first second trimester), as well as a correlation between estrogen levels and the diurnal lumbopelvic pain intensity (second third trimester). The controlled and randomized feasibility study was conducted on 32 pregnant women recruited over a period of 14 months. Among them, 26 (11 in the intervention group and 15 in the control group) participated in the post-intervention visit (retention rate of 81.3%). Adherence rates were similar for supervised and unsupervised exercise sessions, although acceptability was better for supervised sessions compared to unsupervised sessions. At the pre-intervention meeting, participant characteristics were similar between the two groups, except for education level (higher in the control group). Preliminary results showed no significant differences in frequency, intensity, and disability associated with lumbopelvic pain between the groups, although promising trends were observed. This thesis examines hormonal, clinical, biomechanical changes and neuromuscular adaptations in pregnant women with lumbopelvic pain. The results show that a motor control exercise program is safe and feasible with some adjustments, but the stability of the lumbo-pelvic region remains complex and uncertain due to hormonal variations and neuromechanical adaptations during pregnancy. Although the effectiveness of the intervention has not been statistically proven, results suggest that its efficacy could potentially be demonstrated through a larger randomized controlled trial. This thesis also identifies aspects to consider for future studies aimed at improving the management of pregnant women with lumbopelvic pain during pregnancy.
