Avaliação dos efeitos do treinamento do exercício físico aeróbico de curta duração em pacientes hospitalizados com DPOC exacerbado /Knaut, Caroline. January 2015 (has links)
Orientador: Suzana Erico Tanni Minamoto / Coorientador: Victor Zuniga Dourado / Banca: Irma de Godoy / Banca: Oliver Augusto Nascimento / Resumo: Introdução: Exacerbação aguda (EA) é uma importante causa de perda de funções em pacientes que sofrem de doença pulmonar obstrutiva crônica (DPOC). Afeta negativamente a qualidade de vida, a função pulmonar, a fraqueza muscular, a utilização dos recursos da saúde e a sobrevida. Entretanto, o exercício físico realizado durante a exacerbação pode melhorar a qualidade de vida e a capacidade física do paciente. Nesse contexto, o presente estudo visa avaliar a influência da realização do exercício físico em pacientes hospitalizado por exacerbação da DPOC (EADPOC). Objetivo: O presente estudo visa avaliar os efeitos do exercício fisico aeróbio de curta duração nos pacientes hospitalizados por exacerbação aguda de DPOC no escore da dispneia, na qualidade de vida e na capacidade física. Pacientes e Métodos: Vinte e dois pacientes foram randomizados em dois grupos, o grupo controle que recebeu o tratamento clínico padrão e o grupo de intervenção que realizou o treinamento de exercício físico juntamente com os cuidados clínicos. Os pacientes foram submetidos às seguintes avaliações após 48 horas da hospitalização e após um mês da alta: espirometria, avaliação nutricional, distância percorrida no teste de caminhada de seis minutos (DP6), qualidade de vida, ansiedade e depressão, índice de BODE e intensidade de dispneia. O programa de exercício físico foi composto por treinamento aeróbio em esteira ergométrica, duas vezes ao dia, por 15 minutos cada sessão até o período da alta hospitalar. Resultados: O domínio impacto e o escore total da qualidade de vida apresentaram maior incremento no grupo intervenção em relação ao grupo controle (p < 0,001) quando comparado os momentos. Houve melhora de ambos os grupos após um mês de alta hospitalar no domínio atividade quando comparado ao momento basal, mas sem diferença entre os grupos. Além disso, apenas o grupo de intervenção apresentou... / Abstract: Introduction: Acute Exacerbation (AE) is an important cause of impairment of function in chronic obstructive pulmonary disease (COPD) patients. Negatively affects the quality of life, lung function, muscle weakness, the use of health resources and survival. However, physical exercise performed during the exacerbation can improve the quality of life and the physical capacity of the patient. In this context, this study aims to evaluate the influence of aerobic exercise in hospitalized COPD patients with exacerbation (AECOPD). Objective: To evaluate the effects of short duration aerobic exercise in AECOPD on dyspnea score, quality of life and exercise capacity. Patients and Methods: Twenty-two patients were randomized in two groups; the control group received standard medical treatment and the intervention group that performed aerobic exercise training. All patients performed spirometry, nutritional assessment, distance covered on the six-minute walk test (6MWD), quality of life (Saint George Respiratory Questionnaire- SGRQ), anxiety and depression ( The Hospital Anxiety and Depression Scale), BODE index and intensity of dyspnea (Baseline Dyspnea Index and Modified Medical Research Council Score) after 48 hours of hospitalization and after one month of discharge. The exercise program consisted of aerobic training on a treadmill twice a day for 15 minutes until to the discharge. Results: The impact domain and the total score of quality of life showed a higher increase in the intervention group compared to the control group (p<0.001) when compared to the moments. Both groups showed improvement in the activity domain of SGRQ after one month of hospital discharge, but they did not show difference between groups. Furthermore, only the intervention group showed significant improvement in the symptom domain of SGRQ (p<0.001) and baseline dyspnea index (p=0.006) after one month. 6MWD and BODE did not show difference between ... / Mestre

Relação do índice bispetral e da taxa de supressão do traçado do eletroencefalograma com disfunção cognitiva pós-operatória em cirurgia de revascularização do miocárdio /Lineburger, Eric Benedet. January 2014 (has links)
Orientador: José Reinaldo Cerqueira Braz / Banca: Paulo do Nascimento Junior / Banca: Maria Angela Tardelli / Resumo: Introdução: Não está claro na literatura se os valores do índice bispectral (BIS) e da taxa de supressão do traçado de eletroencefalograma (TS), estão relacionados à disfunção cognitiva pós-operatória (DCPO). Objetivo: Avaliar os valores de BIS e TS e sua relação com a DCPO após cirurgia de revascularização do miocárdio (CRM) em pacientes submetidos a anestesia com sevoflurano (SEVO) guiada pelo BIS. Tipo de estudo: Observacional prospectivo. Local do estudo: Hospital de ensino. Pacientes: Noventa pacientes adultos programados para CRM com ou sem circulação extra-corpórea (CEC). Intervenções: A anestesia foi induzida com propofol, remifentanil e atracúrio e mantida com concentrações expiradas de SEVO (ETSEVO) em valores de concentração alveolar mínima (CAMSEVO) adaptada à idade, tendo como alvo valores de BIS de 40-60. O Mini-Exame do Estado Mental (MEEM) para avaliação cognitiva dos pacientes foi aplicado na admissão hospitalar e três meses após a cirurgia. Variáveis estudadas: Os valores de BIS, TS, ETSEVO e CAMSEVO foram registrados a cada 5 minutos durante o procedimento. Redução de um desvio padrão (DP) ou mais no MEEM basal foi definida como DCPO. Resultados: A proporção de DCPO foi de 40%. Os pacientes foram alocados em dois grupos: com (n = 36) ou sem DCPO (n = 54). Não houve diferença significativa na incidência de DCPO entre os pacientes que foram submetidos à CRM com ou sem CEC (p = 1,0). Quanto às características dos pacientes, somente os valores de índice de massa corporal (IMC) foram maiores no grupo sem DCPO (p = 0,009). Valores médios de BSR, ETSEV e MACSEV foram maiores no grupo sem DCPO (p < 0,05). Em uma análise multivariada, valores menores de TS (Razão de Chances-RC 0,008, Intervalo de Confiança-IC 95% [0,001-0,53], p = 0,02), CAMSEVO (RC 0,001, IC 95% [0,001-0,08], p = 0,008), ETSEVO (RC 0,03, IC 95% [0,002-0,66], p = 0,02) e ... / Abstract: BACKGROUND: It is still controversial whether bispectral index (BIS) and burst suppression ratio (BSR) values are related to postoperative cognitive dysfunction (POCD). OBJECTIVE: To evaluate BIS and BSR values and their relation to POCD after coronary artery bypass grafting (CABG) surgery in patients undergoing BIS-guided sevoflurane (SEVO) anaesthesia. DESIGN: Prospective, observational study. SETTING: Teaching hospital. PATIENTS: Ninety adult patients scheduled for on- or off-pump CABG surgery. INTERVENTIONS: Anaesthesia was induced with propofol, remifentanil and atracurium and maintained with end-tidal SEVO (ETSEVO) at age-adapted minimum alveolar concentration (MACSEVO) targeting BIS values of 40-60. Mini-Mental State Examination (MMSE) for cognitive assessment of the patients was applied on hospital admission and at 3 months after surgery. MAIN OUTCOME MEASUREMENTS: BIS, BSR, ETSEVO and MACSEVO values were recorded every 5 minutes during the procedure. A decrease of 1 standard deviation or more from the basal MMSE was defined as POCD. RESULTS: The POCD proportion was 40%. The patients were allocated into two groups: with POCD (n=36) or no POCD (n=54). There was no difference of POCD incidence between patients who were submitted to on- versus off-pump CABG (P=1.0). With regard to the patient's characteristics, only body mass index (BMI) was higher in the no-POCD group (P=0.009). Mean BSR, ETSEVO and MACSEVO values were higher in the no-POCD group (P<0.05). In a multivariable analysis, lower values of BSR (odds ratio-OR 0.008; 95%CI [0.001-0.53]; P=0.02), MACSEVO (OR 0.001; 95%CI [0.001-0.08]; P=0.008), ETSEVO (OR 0.03; 95%CI [0.002-0.66]; P=0.02) and BMI (OR 0.82; 95%CI [0.70-0.96]; P=0.01) were independent predictors of risk for POCD incidence. BIS values did not influence POCD incidence (OR 1.0; 95%CI [0.95-1.11]; P=0.40). CONCLUSION: BIS-guided SEVO anaesthesia titrated to a range between 40 and 60 is not a predictive factor ... / Mestre

The family experience with chronic obstructive pulmonary diseaseRoberts, Della Kim January 1985 (has links)
This study was designed to gain an understanding of the family experience when an adult member has chronic obstructive pulmonary disease (COPD). It is recognized that illness within the family affects the well-being of the family unit and the health of all members. To understand the impact of COPD upon the family, however, the literature provides only knowledge of the experience of the individual who has COPD and the spouse, not that of the family unit. Thus, the purpose of this study was to describe and explain the COPD experience from the perspective of the family unit.
A qualitative method, phenomenology, was chosen for this investigation. Data were collected through semi-structured interviews with eight families who shared their experiences. From the content analysis of these data, three themes that were common throughout the families' accounts were identified and developed to describe and explain family life with COPD.
The first theme, disease-dictated family life, describes four aspects of a common lifestyle that is imposed on the family by the characteristics of COPD. The second theme, isolation, describes the isolation that accompanies the illness experience, for the family group and the individual members within the group. The final theme, family work, describes the four primary challenges the families face and the coping strategies they use to deal with them. These findings revealed that COPD acts as an intense stressor within the family, requiring extensive family work to cope with COPD in a way that maintains the well-being of the family unit. Furthermore, it was found that living with COPD in many ways inhibits the resources within the family and those external sources of support that foster the family's ability to manage the stress associated with living with COPD. The implications for nursing practice and nursing research were delineated in light of the research findings. / Applied Science, Faculty of / Nursing, School of / Graduate

The Role of Spirituality in Ethnic Minority Patients with COPDBell, Keisha 08 1900 (has links)
COPD is the third leading cause of death in the United States and is the sixth leading cause of death for low-to middle income countries (Downs & Appel, 2006; GOLD, 2011). COPD is a largely preventable disease due to the lifestyle factors that heavily contribute to disease onset and severity. Although traditionally COPD research has focused on health outcomes related to risk factors, compliance, comorbid psychological and physical conditions, and treatment interventions, a growing body of research suggests religious and spiritual factors may play an equally important role in health outcomes for several medical conditions, including pulmonary disease. However, studies of this kind have not specifically examined COPD nor have they examined the role of religious and spiritual beliefs in COPD management among ethnic minority patients. As such, the current study aimed to examine whether spiritual ethnic minority patients with COPD hold religious fatalistic attitudes and less active religious problem solving . A sample of 35 ethnic minority patients from the Louis. B. Stokes Cleveland VA Medical Center (LSCVAMC) Outpatient Pulmonary Clinic in Cleveland, OH. were recruited to participate in the study. Due to the acknowledgeable limitations of the present study, results are preliminary but convey associations between religious health fatalistic beliefs and religious problem solving approaches. Implications and areas of future study are discussed.

A phenomenological study of hospital readmissions of Chinese older people with chronic obstructive pulmonary disease / CUHK electronic theses & dissertations collectionJanuary 2015 (has links)
Hospital readmission is prevalent among people with chronic obstructive pulmonary disease (COPD), particularly among older people in Hong Kong. Evidence shows that hospital readmissions exert a considerable impact on patients. Studies in this area primarily identify various associative factors based on the perspectives of health professionals. However, these factors are inadequate in illustrating the needs of older people and in illuminating the phenomenon of hospital readmissions. A thorough understanding of the issue can be achieved if the related experiences are interpreted from the perspective of the patients and in terms of their context. Understanding of their experiences has paramount significance in uncovering the unmet needs of patients and in informing the provision of healthcare services. Yet, there is a dearth of studies unfolding the experiences of Chinese older people. / This study aimed to explore and describe the lived experience of hospital readmissions of Chinese older people with COPD and to identify Chinese socio-cultural influences on the experience. Understanding was acquired through descriptive phenomenology. Twenty-two Chinese older people aged 62 to 89 were recruited by purposive sampling. They had been readmitted 4 to 14 times in the previous year. The older people were interviewed once during their hospitalization, and their readmission experiences were elicited from these unstructured interviews. Narrative descriptions were analyzed using the phenomenological method described by Giorgi (1985). / The general structure of the lived experience of hospital readmissions of Chinese older people with COPD reveals that older people refrain from unnecessary readmissions because they regard hospital care as the last resort in relieving breathlessness. When their breathlessness becomes intolerable, they perceive the urgency of surviving the distress. Craving for survival, they seek hospital readmission, which provides them immediate relief from the imminent threat. After being readmitted to a hospital, they feel powerless when their need for hospital care is disregarded by their doctors. Considering themselves as demanding to their families in daily lives, older people remain conscious of relieving their burden during their periods of hospital readmission because they regard this as the only opportunity to relieve their burden. Older people come to realize hospital readmissions are unavoidable after they put every effort to refrain from it but hospital care remains necessary. They further rationalize hospital readmissions as inevitable and resign themselves to it because of their perception of aging, doctors’ accounts of COPD, experience with and knowledge of the disease, and belief in fate. This acceptance of the inevitability of hospital readmissions precipitates an attitudinal shift toward the belief of living for the moment. Their past experiences inspire them to be satisfied with the current state of living and engage the present. This positive outlook enables them to embrace the experiences of hospital readmissions into their lives. Six invariant constituents emerged from the lived experience. The constituent “refraining from unnecessary readmissions” describes how older people manage their diseases in relation to hospital readmissions. “Craving for survival” explains why they seek hospital readmissions. “Feeling being disregarded and powerless” and “being conscious of relieving burden to families” characterize their experience of hospital readmissions. “Resigning to hospital readmissions” illustrates how they understand the recurrence of this phenomenon and “living for the moment” illuminates how they live with their experiences. / A deep understanding of hospital readmissions is embodied in the experiences of older people. The findings emphasize that hospital readmissions among Chinese older people are complex experiences shaped by their sociocultural context. The meanings of hospital readmissions to older people are influenced by their assumption of a submissive patient role, collectivism, external attribution style, and past life experiences. Although older people appear to accept and cope well with hospital readmissions, this study uncovers their needs as they move to and fro the hospital and home. The findings of this study offer implications in promoting the wellness of Chinese older people as they go through this revolving door. / 再次住院在患有慢性阻塞性肺病人士中相當普遍,尤其是在中國老年患者。研究證據顯示再次住院對病人有很大的影響。現有的研究偏重於從醫務人員角度尋找不同的關聯因素,但該些因素並不足以反映老年人的需要以及解釋再次住院的現象。只有透過病人的觀點以及結合他們的背景來闡釋這些相關經驗,才能作出深入了解。了解病人的再次住院經驗有助於找出病人的需要以及指引醫療服務的提供。然而,有關中國老年人再次住院經驗的探討相當缺乏。 / 是次研究目的是探討和描述患有慢性阻塞性肺病的中國老年人再次住院的體驗,以及認識中國社會文化對再次住院經驗的影響。研究採用描述現象學方法。研究以立意抽樣方式選取了22名62至89歲的中國老年人。他們在去年入院次數為4至14次。這些老年人在住院期間均接受一次非結構式訪談以了解他們的再次住院經驗。這些敘述性描寫再按 Giorgi (1985) 的現象學方法作出分析。 / 患有慢性阻塞性肺病中國老年人再次住院的體驗的通用結構顯示他們避免不必要的再次住院,因為他們將住院護理視為紓緩呼吸困難的最後方法。當他們的呼吸困難惡化至無法忍受,他們會感受到從危病中活下來的迫切性。因著渴望生存的意識,他們尋求再次住院以即時消除緊迫的生命威脅。再次入院後,對於醫生漠視其住院護理的需要,他們感到無力。由於考慮到他們在日常生活中對家人的需求頗多,老年人以再次住院其間來減輕家庭負擔,因他們視這其間為唯一能減輕家庭負擔的機會。儘管老年人盡能力以避免再次入院,但他們依然需要住院護理,老年人逐漸意識到再次住院為無可避免。由於老年人對於老化的感知、醫生對慢性阻塞性肺病的解明、患病經驗和對疾病的相關知識以及相信命運的看法,他們更將再次住院合理化為無可避免並順從。接受再次住院為無可避免促成他們的態度轉變為活在當下。過去的經驗令他們對目前的生活感到滿意並希望活在當下。這個正面想法令他們將再次住院接納為生活的一部份。六個不變組成要素呈現於老年人的再次住院體驗當中。組成要素「避免不必要的再次住院」描述老年人如何管理慢性阻塞性肺病以避免再次住院。「渴望生存」解釋了他們尋求再次住院的原因。「感到被忽略和無力」以及「減輕家庭負擔的意識」敘述了他們再次住院的經驗。「順從再次住院」說明了他們對再次住院現象發生的理解,而「活在當下」說明了他們如何接納再次住院經驗。 / 對於再次住院的深入了解具體表現於老年人的經驗當中。是次研究結果強調,老年人再次住院是由他們的社會文化背景塑造而成的複雜經驗。對於老年人而言,再次住院的意義受到他們對順從性病人角色的假設、集體主義觀念、外部歸因以及過往的生活經驗所影響。雖然老年人似乎接受並適應再次住院,是次研究發現了他們在這現象中的需要。研究結果對於促進再次住院的中國老年人的健康帶來新的啟示。 / Tang, Wing Ki. / Thesis (Ph.D.)--Chinese University of Hong Kong, 2015. / Includes bibliographical references (leaves 342-393). / Abstracts also in Chinese. / Title from PDF title page (viewed on 05, October, 2016). / Detailed summary in vernacular field only. / Detailed summary in vernacular field only. / Detailed summary in vernacular field only. / Detailed summary in vernacular field only.

The Vitamin B-6 Status of Patients with Chronic Obstructive Pulmonary DiseaseAnurak Bhunthurat 12 1900 (has links)
The problem of this study is to determine the vitamin B-6 status of patients who have chronic obstructive pulmonary disease (COPD). Erythrocyte aspartate transaminase assay was the method for measuring vitamin B-6 status. The vitamin B-6 status was examined in thirty subjects (ten COPD subjects and twenty control subjects). An unpaired t-test was used to compare the vitamin B-6 status of the COPD group versus the control group. Four determinants (percentage stimulation, ratio of basal to stimulated activity, basal activity, and stimulated activity) were used to determine vitamin B-6 status in both groups of subjects. Percentage stimulation and ratio of basal to stimulated activity were not significantly different (control group versus COPD group) at the .05 level. However, two of ten COPD subjects had values for percentage stimulation that were two standard deviations above the mean, indicating a poor B-6 status. In contrast, basal activity and stimulated activity of erythrocyte aspartate transaminase were found to be significantly lower at the .05 level in the COPD group than the control group. Therefore, the COPD subjects as a group had some biochemical characteristics of a lower level of vitamin B-6 than the controls.
