Fisioterapia respiratória e sua aplicabilidade no período pré-operatório de cirurgia cardíaca

Procedimentos cirúrgicos torácicos podem alterar a mecânica respiratória, repercutindo na função pulmonar. A presença de profissionais fisioterapeutas é fundamental no preparo e na reabilitação dos indivíduos que são submetidos à cirurgia cardíaca, visto que dispõem de um grande arsenal de técnicas. O objetivo foi verificar a efetividade de exercícios respiratórios, com e sem a utilização de dispositivos, e o treinamento muscular respiratório pré-cirurgia cardíaca na redução das complicações pulmonares pós-operatórias. Mesmo existindo controvérsias a respeito de qual técnica utilizar, estudos demonstram a eficácia da fisioterapia respiratória pré-cirúrgica na prevenção e na redução de complicações pulmonares pós-operatórias.

Influência do biofeedback respiratório associado ao padão quiet breathing sobre a função pulmonar e hábitos de respiradores bucais funcionais

OBJETIVOS: Avaliar os efeitos da utilização do biofeedback respiratório (BR) associado ao padrão quiet breathing sobre a perimetria torácica, função pulmonar, força dos músculos respiratórios e os seguintes hábitos de respiradores bucais funcionais (RBF): vigília de boca aberta, boca aberta durante o sono, baba no travesseiro, despertar difícil, ronco e sono inquieto. MÉTODOS: Foram avaliadas 20 crianças RBF, as quais foram submetidas a 15 sessões de BR por meio do biofeedback pletsmovent (MICROHARD® V1.0), o qual proporciona o biofeedback dos movimentos tóraco-abdominais. Perimetria torácica, espirometria e medidas das pressões respiratórias máximas estáticas foram realizadas antes e após a terapia. Questões respondidas pelos responsáveis foram utilizadas para avaliar os hábitos dos RBF. Os dados foram analisados por meio de teste t de Student para dados pareados e testes não paramétricos. RESULTADOS: O uso do BR associado ao padrão quiet breathing não produziu alterações significativas na perimetria torácica e nos valores de volume expiratório forçado no primeiro segundo (VEF1), capacidade vital forçada (CVF), pico de fluxo expiratório (PFE), índice de Tiffeneau (IT) e na pressão expiratória máxima (PEmáx). Entretanto, a pressão inspiratória máxima (PImáx) apresentou diferença estatisticamente significativa (-53,6 ± 2,9 cmH2O vs. -65,0 ± 6,0 cmH2O; p< 0,05) e ocorreram mudanças significativas nos hábitos avaliados. CONCLUSÃO: Os resultados permitem concluir que o BR associado ao padrão quiet breathing melhora a força da musculatura inspiratória e hábitos em RBF, podendo ser, portanto, utilizado como uma das formas de terapia nesses indivíduos.

Correlações entre os níveis de L-carnitina plasmática, o estado nutricional e a função ventilatória de portadores de doença pulmonar obstrutiva crônica

OBJETIVO: Avaliar os níveis de L-carnitina livre no plasma, o estado nutricional, a função pulmonar e a tolerância ao exercício em pacientes com doença pulmonar obstrutiva crônica e verificar as correlações entre a composição corporal e as frações de L-carnitina no plasma. MÉTODOS: Quarenta pacientes entre 66,2±9 anos, com diagnóstico clínico de doença pulmonar obstrutiva crônica, foram divididos em dois grupos: G1, com índice de massa corporal menor que 20kg/m², e G2, com índice de massa corporal maior que 20kg/m². Foram mensurados os parâmetros espirométricos, a tolerância ao exercício no teste de caminhada, a força muscular respiratória, a composição corporal por meio da impedância bioelétrica e as dosagens da L-carnitina plasmática, através de amostras de sangue. RESULTADOS: Foram observados menores valores das variáveis espirométricas (p<0,01), da força muscular respiratória e dos níveis de L-carnitina nos pacientes do G1; porém, não houve diferença entre os grupos quanto à capacidade de realizar exercício físico dinâmico de baixa intensidade. Correlações significativas entre o percentual de gordura e os níveis de L-carnitina plasmática foram observadas nos pacientes (r=0,53 com p<0,002); sendo que, nos pacientes com índice de massa corporal menor que 18kg/m², essa relação aumentou (r<0,73 com p<0,01). CONCLUSÃO: Na doença pulmonar obstrutiva crônica, a desnutrição está associada tanto aos prejuízos da função pulmonar e da força muscular respiratória, quanto aos baixos níveis de L-Carnitina plasmática.

Involvement of organic systems in golden retriever X-linked muscular dystrophy

Duchenne muscular dystrophy is a lethal genetic disease characterized by progressive muscle degeneration that usually had been used the Golden Retriever as a model for studying the disease (GRMD - Golden Retriever Muscular Dystrophy). A total of 16 male dystrophic Golden Retrievers dogs between 5 to 51 months of age were examined in the present study. The animals were classified as dystrophic according to two simultaneous complementary criteria: genotypic analysis and serum creatine kinase levels. The macroscopic abnormalities of the different organs and tissues and histopathological features were described using hematoxylin-eosin. The lesions in the skeletal muscles associated with the digestive problems resulted in cachexia with different intensities in all the dystrophic dogs. Cardiac muscle involvement was found in 87,5% of the GRMD dogs resulting, however, in cardiac failure in only 18,8% of the animals. The musculature of the diaphragm was hypertrophic in all affected animals resulting in progressive respiratory muscle weakness and at later stages in respiratory failure (81,25%). The liver abnormalities found in dystrophic dogs were originated mainly from heart disease and developed progressively. Hyperemia of mucosa and granular material indicated changes in the functioning and emptying of bladder. The germinative lineage cells presented moderate to severe degeneration probably due to degeneration of the scrotum and cremaster muscle which prevented the proper thermo-regulation of the testicle. Our results highlight the fact that there is significant impairment of the cardiac, respiratory and skeletal muscle systems in GRMD dogs since the age of five months. In addition, significant alterations of the gastrointestinal tract, urinary and reproductive systems are indicating the presence of degenerative lesions in the smooth musculature.

Existe correlação entre força muscular com o teste de caminhada de seis minutos em idosos institucionalizados?

The six-minute walking test can be affected by several variables, among them, the respiratory and peripheral muscle strength. The objective of this study was to correlate the respiratory muscle strength (maximum inspiratory pressure – MIP; and maximum expiratory pressure – MEP) and the hand grip test (HGT)with the six minute walking test distance in institutionalized elderly. It was included in this study 9 institutionalized elderly with age over 70 years old, both gender, evaluated by means of manometer, dynamometry and six minute walking test. The data were correlated by using the Pearson’s correlation test and the Spearman correlation test. From the evaluated elderly, it was four men and five women, with mean age: 78.8±7.3 years old, MIP: 75.7±33.6 cmH2O, MEP: 62.4±25.0 cmH2O, HGT: 20.4±6.2 kgf (right member) and 20.7±6.8 kgf (left member) and the distance on six minute walking test: 238.5±99.0 meters. There was correlation between expiratory strength and hand grip of both members with the distance on the six minute walking test. It is possible to conclude that there are correlation between expiratory muscle strength with the hand grip test and the functional capacity in institucionalized elderly.

Preoperative therapy restores ventilatory parameters and reduces length of stay in patients undergoing myocardial revascularization

Introduction: The frequency of surgical procedures has increased steadily in recent decades, including the myocardial revascularization.Objectives: To demonstrate the importance of physiotherapy in the preoperative period of cardiac surgery in relation to the reduction of hospital stay, changes in lung volumes and respiratory muscle strength.Methods: We conducted a prospective study with patients undergoing myocardial revascularization, the Hospital das Clinicas da Universidade Estadual Paulista (UNESP)/Botucatu - SP. We evaluated 70 patients of both genders, aged between 40 and 75 years, subdivided into two groups: group I - 35 patients of both genders, who received a written protocol guidance, breathing exercises and respiratory muscle training in the preoperative period and group II - 35 patients of both genders, who received only orientation of the ward on the day of surgery. This study was approved by the Ethics Committee of UNESP /Botucatu - SP.Results: Maximal inspiratory pressure in third postoperative day and fifth postoperative day and significant difference between groups, being better for the intervention group. Expiratory pressure was significant in fifth postoperative day in the intervention group compared to controls. The difference of length of hospital stay in the postoperative was found between the groups with shorter hospital stay in the group receiving preoperative therapy.Conclusion: Physical therapy plays an important role in the preoperative period, so that individuals in the intervention group more readily restored the parameters evaluated before surgery, in addition, there was a decrease in the time of the postoperative hospital stay. Thus, it is thought the cost-effectiveness of a program of preoperative physiotherapy.

Weakness of expiratory muscles and pulmonary complications in malnourished patients undergoing upper abdominal surgery

Background and objective: Malnutrition is prevalent in hospitalized patients and causes systemic damage including effects on the respiratory and immune systems, as well as predisposing to infection and increasing postoperative complications and mortality. This study aimed to assess the impact of malnutrition on the rate of postoperative pulmonary complications, respiratory muscle strength and chest wall expansion in patients undergoing elective upper abdominal surgery. Methods: Seventy-five consecutive candidates for upper abdominal surgery (39 in the malnourished group (MNG) and 36 in the control group (CG)) were enrolled in this prospective controlled cohort study. All patients were evaluated for nutritional status, respiratory muscle strength, chest wall expansion and lung function before surgery. Postoperative pulmonary complications (pneumonia, tracheobronchitis, atelectasis and acute respiratory failure) before discharge from hospital were also evaluated. Results: The MNG showed expiratory muscle weakness (MNG 65 +/- 24 vs CG 82 +/- 22 cm H2O; P < 0.001) and decreased chest wall expansion (P < 0.001), whereas inspiratory muscle strength and lung function were preserved (P > 0.05). The MNG also had a higher incidence of postoperative pulmonary complications compared with the CG (31% and 11%, respectively; P = 0.05). In addition, expiratory muscle weakness was correlated with BMI in the MNG (r = 0.43; P < 0.01). The association between malnutrition and expiratory muscle weakness increased the likelihood of postoperative pulmonary complications after upper abdominal surgery (P = 0.02). Conclusions: These results show that malnutrition is associated with weakness of the expiratory muscles, decreased chest wall expansion and increased incidence of pulmonary complications in patients undergoing elective upper abdominal surgery.
