Percepção de dispneia em repouso e em atividades físicas habituais em diferentes graus de obesidade / Perception of dyspnea at rest and in daily physical activities in varying degrees of obesity

JUSTIFICATIVA E OBJETIVO: Dispneia é uma experiência subjetiva de desconforto respiratório, cujos mecanismos fisiopatológicos e de percepção são complexos. O objetivo deste estudo foi avaliar a percepção de dispneia dos obesos em repouso e em atividades físicas habituais, utilizando três escalas de dispneia, e verificar a influência do peso corporal na percepção de dispneia crônica. MÉTODOS: Estudo transversal, incluindo 140 pacientes com peso normal e sobrepeso (grupo controle) e obesidade graus I, II e III, que foram subdivididos em seis subgrupos. Dispneia crônica foi avaliada utilizando-se descritores de dispneia e percepção de dispneia em repouso e em atividades físicas habituais por meio três escalas de dispneia: Escala Analógica Visual, Escala de Diagrama de Custo de Oxigênio e Medical Research Council modificada. RESULTADOS: Os grupos tiveram distribuição homogênea quanto a gênero, idade, cor da pele, altura, status tabágico e atividade física. O peso corporal médio foi 109,5±30,9kg e o índice de massa corporal de 39,91±10,57kg/m², com diferenças significativas entre os grupos (p<0,001). Nenhum dos pacientes referiu dispneia em repouso em posição sentada, nas três escalas utilizadas. Houve diferenças significativas entre os grupos quanto à percepção de dispneia em atividades físicas habituais, que se intensificaram nos grupos com o índice de massa corporal mais elevada (p<0,0001). CONCLUSÃO: Indivíduos obesos livres de comorbidades que influenciam a percepção de dispneia não demonstram dispneia em repouso; todavia, apresentaram dispneia crônica em atividades físicas habituais da vida diária, que sofre influência do aumento progressivo do peso corporal...

BACKGROUND AND OBJECTIVE: Dyspnea is a subjective experience respiratory distress whose pathophysiological mechanisms and perception are complex. The objective of this study was to evaluate the perception of dyspnea in obese at rest and in habitual physical activities, using three scales of dyspnea, and check the influence of body weight on the perception of chronic dyspnea. METHDOS: Cross-sectional study including 140 patients with normal weight and overweight (control group) and obesity grades I, II and III, which were subdivided into six subgroups. Chronic dyspnea was assessed using descriptors of dyspnea and perception of dyspnea at rest and in daily physical activities through three dyspnea scales: Visual Analog Scale, Oxygen Cost Diagram scale and modified Medical Research Council. RESULTS: The groups were homogeneous distributed according to gender, age, skin color, height, smoking status and physical activity. The average body weight was 109.5±30.9kg and body mass index 39.91±10.57kg/m², with significant differences between groups (p<0.001). None of the patients reported dyspnea at rest in a sitting position according to the three scales used. There were significant differences between the groups regarding the perception of dyspnea in daily physical activities, which were intensified in the groups with higher body mass index (p<0.0001). CONCLUSION: Obese individuals with no comorbidities which can influence the perception of dyspnea had no dyspnea at rest; however, they presented with chronic dyspnea in daily physical activities of daily living, influenced by the progressive increase in body weight...

Função diastólica do ventrículo esquerdo em obesos graves em pré-operatório para cirurgia bariátrica / Left ventricular diastolic function in morbidly obese patients in the preoperative for bariatric surgery

FUNDAMENTO: Obesidade é uma doença crônica, multifatorial, associada a aumento do risco cardiovascular, especialmente a insuficiência cardíaca diastólica. OBJETIVO: Avaliar a função diastólica do ventrículo esquerdo em obesos graves em pré-operatório para cirurgia bariátrica, relacionando com os fatores de risco cardiovascular e a estrutura cardíaca. MÉTODOS: Trata-se de um estudo transversal, com 132 pacientes candidatos a cirurgia bariátrica, submetidos a avaliação ecocardiográfica transtorácica e dos fatores de risco cardiovascular, sendo: 97 mulheres (73,5%), idade média de 38,5 ± 10,5 anos e IMC de 43,7 ± 7,2 Kg/m². Foram divididos em três grupos: 61 com função diastólica normal, 24 com disfunção diastólica leve e 47 com disfunção diastólica moderada/grave, dos quais 41 com disfunção diastólica moderada (padrão pseudonormal) e seis com disfunção diastólica grave (padrão restritivo). RESULTADOS: Hipertensão arterial sistêmica, idade e gênero foram diferentes nos grupos com disfunção diastólica. Os grupos com disfunção tiveram maior diâmetro do átrio esquerdo, do ventrículo esquerdo, volume do átrio esquerdo em quatro e duas câmaras, índice de volume atrial esquerdo e índice de massa do ventrículo esquerdo corrigido para a superfície corpórea e para altura. CONCLUSÃO: A elevada frequência de disfunção diastólica do ventrículo esquerdo na fase pré-clínica em obesos graves justifica a necessidade de uma avaliação ecocardiográfica criteriosa, com o objetivo de identificar indivíduos de maior risco, para que medidas de intervenção precoce sejam adotadas.

BACKGROUND: Obesity is a chronic and multifactorial disease, associated with increased cardiovascular risk, especially diastolic heart failure. OBJECTIVE: To evaluate left ventricular diastolic function in morbidly obese patients in the pre-operative for bariatric surgery, correlating it with cardiovascular risk factors and heart structure. METHODS: This is a cross-sectional study with 132 patients eligible for bariatric surgery submitted to transthoracic echocardiography assessment and of cardiovascular risk factors, as follows: 97 women (73.5%), mean age 38.5 ± 10.5 years and BMI of 43.7 ± 7.2 kg / m². Patients were divided into three groups: 61 with normal diastolic function, 24 with mild diastolic dysfunction and 47 with moderate/severe diastolic dysfunction, of which 41 with moderate diastolic dysfunction (pseudonormal pattern) and six with severe diastolic dysfunction (restrictive pattern). RESULTS: Hypertension, age and gender were different in the groups with diastolic dysfunction. Groups with dysfunction had higher left atrial diameter, left ventricular diameter, left atrial volume in four and two chambers, left atrial volume index and left ventricular mass index corrected for body surface area and height. CONCLUSION: The high frequency of left ventricular diastolic dysfunction in the preclinical phase in morbidly obese patients justifies the need for careful echocardiographic assessment, aiming at identifying individuals at higher risk, so that early intervention measures can be carried out.

Effects of progressive increase in body weight on lung function in six groups of body mass index.

OBJECTIVE: To evaluate the effects of the progressive increase in body weight on lung function by oxygen peripheral saturation, spirometry and maximal respiratory pressures in different degrees of obesity. METHODS: Cross-sectional study including 140 patients in clinical and surgical evaluation for obesity treatment. The selected patients were divided into six groups of body mass index (BMI), including a control group of non-obese and a subdivision for the morbidly obese into three subgroups. RESULTS: Significant differences were demonstrated between the groups regarding oxygen peripheral saturation (SpO2) (p < 0.001), forced vital capacity (FVC) (p < 0.002, p < 0.02) and forced expiratory volume in one second (FEV1) (p < 0.001, p < 0.03) in relative and absolute values, respectively. Group VI (BMI > 50.9 kg/m²) showed significant differences (SpO2, FVC and FEV1) when compared with the other groups (except group V) and group V (BMI > 45 to 49.9 kg/m²) with the group control. The other variables (FEV1/FVC ratio, forced expiratory flow 25-75 [FEF25-75] and maximal respiratory pressure) did not show any statistical differences. CONCLUSION: Lung function is influenced by the progressive increase in BMI, with changes in lung function better demonstrated when BMI > 45 kg/m²; these changes are more evident when BMI > 50.9 kg/m².

Efeitos do aumento progressivo do peso corporal na função pulmonar em seis grupos de índice de massa corpórea / Effects of progressive increase in body weight on lung function in six groups of body mass index

OBJETIVO: Avaliar os efeitos do aumento progressivo do peso corpóreo na função pulmonar através da saturação periférica de oxigênio, espirometria e pressões respiratórias máximas em diferentes graus de obesidade. MÉTODOS: Estudo transversal, incluindo 140 pacientes em avaliação clínica e cirúrgica para tratamento de obesidade. Os pacientes selecionados foram divididos em seis grupos de índice de massa corpórea (IMC), incluindo um grupo-controle de não obesos e a subdivisão dos obesos mórbidos em três subgrupos. RESULTADOS: Foram demonstradas diferenças significativas entre os grupos na saturação periférica de oxigênio (SpO2) (p < 0,001), capacidade vital forçada (CVF) (p < 0,002; p < 0,02) e volume expiratório forçado no primeiro segundo (VEF1) (p < 0,001; p < 0,03), em valores relativos e absolutos, respectivamente. O grupo VI (IMC > 50,9 kg/m²) demonstrou diferenças significativas (SpO2, CVF e VEF1) em relação aos demais grupos (exceto grupo V) e o grupo V (IMC > 45 a 49,9 kg/m²) em relação ao grupo-controle. As demais variáveis (razão VEF1/CVF, fluxo expiratório forçado 25-75 [FEF25-75] e pressões respiratórias máximas) não apresentaram diferenças estatísticas. CONCLUSÃO: A função pulmonar sofre influência do aumento progressivo do IMC, com as alterações funcionais respiratórias sendo mais bem demonstradas com o IMC > 45 kg/m² e ficando bem mais acentuadas quando o IMC excede a 50,9 kg/m².

Prevalence and severity of asthma in obese adult candidates for bariatric surgery.

OBJECTIVE: To determine the prevalence of asthma in a group of obese adult candidates for bariatric surgery and to evaluate the severity of asthma in this group of patients. METHODS: This was a cross-sectional study involving 363 obese adults (body mass index > 35 kg/m²) evaluated by a pulmonologist, using clinical evaluation as a diagnostic tool for asthma. All patients underwent clinical evaluation and spirometry and were divided into two groups (asthma and control). The patients with asthma were stratified by the severity of asthma. RESULTS: The prevalence of asthma in the obese population studied was 18.5% (95% CI: 14.5-22.4). That prevalence was 20.4% (95% CI: 16.2-24.5) and 13.7% (95% CI: 10.1-17.2) in the women and the men, respectively. Asthma symptoms in the last twelve months were present in 8.0% (95% CI: 5.2-10.7), and the initial manifestation of asthma symptoms occurred during childhood/adolescence in 17.4% (95% CI: 13.5-21.3). In the asthma group, intermittent asthma was present in 29 patients (43.3%), mild persistent asthma in 7 (10.4%), moderate asthma in 25 patients (37.3%), and severe persistent asthma in 6 (9.0%). CONCLUSIONS: Using clinical evaluation as the diagnostic criterion, we found the prevalence of asthma to be high in this group of obese adults. Asthma was more common in females, and the initial manifestation of asthma symptoms more commonly occurred during childhood/adolescence. The severity of asthma in this group of obese adults was within the range of mean values predicted for the general population. Intermittent asthma, mild persistent asthma, and moderate persistent asthma predominated.

OBJETIVO: Determinar a prevalência de asma em um grupo de adultos obesos, candidatos a cirurgia bariátrica e avaliar a gravidade da asma neste grupo de pacientes. MÉTODOS: Estudo transversal, envolvendo 363 pacientes obesos adultos (índice de massa corpórea > 35 kg/m²) avaliados por um médico pneumologista, utilizando a avaliação clínica como instrumento diagnóstico de asma. Todos os pacientes foram submetidos à avaliação clínica e espirometria e foram divididos em dois grupos (asma e controle). Os pacientes com asma foram classificados conforme a gravidade da doença. RESULTADOS: A prevalência de asma na população de obesos estudada foi de 18,5 por cento (IC95 por cento: 14,5-22,4). Essa prevalência nas mulheres e nos homens foi de 20,4 por cento (IC95 por cento: 16,2-24,5) e 13,7 por cento (IC95 por cento: 10,1-17,2), respectivamente. Havia sintomas de asma nos últimos doze meses em 8,0 por cento (IC95 por cento: 5,2-10,7), e houve manifestação inicial dos sintomas de asma na infância/adolescência em 17,4 por cento (IC95 por cento: 13,5-21,3). No grupo asma, asma intermitente estava presente em 29 pacientes (43,3 por cento); asma persistente leve, em 7 (10,4 por cento); asma moderada, em 25 (37,3 por cento); e asma persistente grave, em 6 (9,0 por cento). CONCLUSÕES: A prevalência de asma neste grupo de adultos obesos, utilizando-se a avaliação clínica como critério diagnóstico, mostrou-se elevada, com predomínio no sexo feminino e com manifestação inicial dos sintomas de asma na infância/adolescência. A gravidade da asma neste grupo de obesos adultos esteve entre os valores médios estimados para a população geral, com uma maior proporção de asma intermitente, asma persistente leve e asma persistente moderada.

Envelhecimento pulmonar acelerado em pacientes com obesidade mórbida / Accelerated lung aging in patients with morbid obesity

OBJETIVO: Determinar a idade pulmonar de pacientes com obesidade mórbida e compará-la com a idade cronológica desses pacientes, ressaltando o dano precoce da obesidade mórbida sobre os pulmões. MÉTODOS: Estudo transversal, prospectivo e aberto que envolveu 112 indivíduos: 78 pacientes com obesidade mórbida (grupo de estudo) e 34 indivíduos não obesos e com função pulmonar normal (grupo controle). Todos os pacientes realizaram espirometria para a determinação da idade pulmonar. A idade pulmonar e a idade cronológica dos indivíduos em cada grupo foram comparadas isoladamente e entre os grupos. RESULTADOS: A diferença entre a idade pulmonar e a idade cronológica no grupo com obesidade mórbida foi significativa (p < 0,0001; IC95 por cento: 6,6-11,9 anos), com uma diferença média de 9,1 ± 11,8 anos. A diferença da idade pulmonar entre o grupo de estudo e o grupo controle foi significativa (p < 0,0002; IC95 por cento: 7,5-16,9 anos), com uma diferença média de 12,2 ± 2,4 anos. A idade pulmonar demonstrou uma correlação positiva com a idade cronológica e o índice de massa corpórea (IMC) e uma correlação negativa com as variáveis espirométricas (p < 0,0001 para todos). A análise de regressão linear múltipla identificou as variáveis IMC e idade cronológica (p < 0,0001) como fatores preditivos significativos da idade pulmonar. CONCLUSÕES: A idade pulmonar está aumentada em pacientes com obesidade mórbida, sugerindo dano precoce e envelhecimento pulmonar acelerado, como evidenciado pela discrepância entre a idade cronológica e idade pulmonar. A determinação da idade pulmonar pode se tornar uma nova ferramenta na compreensão dos resultados da função pulmonar para pacientes e profissionais da saúde em relação ao controle da obesidade.

OBJECTIVE: To determine the lung age of patients with morbid obesity and to compare it with the chronological age of these patients, emphasizing the premature damage that morbid obesity does to the lungs. METHODS: An open, prospective cross-sectional study comprising 112 individuals: 78 patients with morbid obesity (study group); and 34 non-obese individuals with normal pulmonary function results (control group). All of the patients underwent spirometry for the determination of lung age. The lung age and the chronological age of the individuals in each group were compared in isolation and between the two groups. RESULTS: The difference between lung age and chronological age in the group with morbid obesity was significant (p < 0.0001; 95 percent CI: 6.6-11.9 years), the mean difference being 9.1 ± 11.8 years. The difference between the study group and the control group in terms of lung age was significant (p < 0.0002; 95 percent CI: 7.5-16.9 years), the mean difference being 12.2 ± 2.4 years. Lung age correlated positively with chronological age and body mass index (BMI), whereas it correlated negatively with the spirometric variables (p < 0.0001 for all). Multiple linear regression analysis identified BMI and chronological age (p < 0.0001) as significant predictors of lung age. CONCLUSIONS: Lung age is increased in patients with morbid obesity, suggesting premature damage and accelerated lung aging, as evidenced by the discrepancy between chronological age and lung age. The determination of lung age might become a new tool for understanding pulmonary function results, for patients as well as for health professionals, in relation to obesity control.

OBJETIVOS: Determinar o local de internação no pós-operatório de cirurgia bariátrica primária e verificar as complicações clínicas-cirúrgicas que justificassem internação em unidade de terapia intensiva, inclusive morte. MÉTODOS: Estudo transversal, prospectivo, aberto, sendo avaliados 120 pacientes submetidos à cirurgia bariátrica primária por vídeolaparoscopia no período de maio de 2007 a abril de 2008 em um hospital terciário. Utilizou-se o índice de Aldrete e Kroulik para liberação da sala de recuperação pós-anestésica e definição do local de encaminhamento no pós-operatório. RESULTADOS: Entre os 120 pacientes, havia 83 mulheres e 37 homens, com média de idade 35,4 ± 10,5 anos (18 a 66 anos), índice de massa corpórea médio 45,6 ± 10,5. O tempo entre admissão hospitalar e inicio da cirurgia foi de 140,7 ± 81,8 minutos, o tempo cirúrgico 105,0 ± 28,6 minutos, o tempo de permanência na sala de recuperação pós-anestésica foi 125,0 ± 38,0 minutos e tempo de internação hospitalar 47,7 ± 12,4 horas, com 100 por cento dos pacientes deambulando em 24 horas. O índice de Aldrete e Kroulik da sala de recuperação pós-anestésica alcançou pontuação de 10 com 120 minutos em todos os pacientes, com sobrevida de 100 por cento. CONCLUSÃO: Com o uso do índice Aldrete e Kroulik na sala de recuperação pós-anestésica de bypass gástrico por videolaparoscopia em cirurgia bariátrica primária, nenhum paciente foi internado em unidade de terapia intensiva e nenhuma complicação maior foi observada.

OBJECTIVE: The purpose of this study was to determine the place of stay at postoperative and to verify medical-surgical complications that would justify admission to the intensive care unit, including death. METHODS: Cross-over, prospective, open study that evaluated 120 patients who were submitted to primary bariatric surgery by video laparoscopy from May 2007 to April 2008 in a tertiary hospital. The Aldrete Kroulik index was used for release from the post-anesthesia recovery room and to define where the patient should be routinely referred for postoperative. RESULTS: Among the 120 patients, 83 were women and 37 men with a mean age ranging from 35.4 ± 10.5 years (18 to 66 years), body mass index 45.6 ± 10.5. The time between hospital admission and start of surgery was 140.7 ± 81.8 minutes, surgery time was 105 ± 28.6 minutes, time of post-anesthesia recovery room was between 125 ± 38 minutes and length of hospital stay was 47.7 ± 12.4 hours, with 100 percent of the patients walking in 24 hours. The Aldrete and Kroulik index in the post-anesthesia recovery room achieved scores of 10 to 120 minutes in all patients, with a 100 percent survival . CONCLUSION: Using the Aldrete and Kroulik index in the post-anesthesia of gastric bypass by video laparoscopy in primary bariatric surgery, no patient was admitted in intensive care unit and no major complication was observed.
