Evaluation of lung volumes, vital capacity and respiratory muscle strength after cervical, thoracic and lumbar spinal surgeryAvaliação dos volumes pulmonares, capacidade vital e força dos músculos respiratórios no pós-operatório de cirurgia na coluna cervical, torácica e lombar Marcio Aparecido Oliveira I , Milena Carlos Vidotto II , Oliver Augusto Nascimento III , Renato Almeida IV , Ilka Lopes Santoro V , Evandro Fornias Sperandio VI , José Roberto Jardim VII , Mariana Rodrigues Gazzotti VIII Universidade Federal de São Paulo ABSTRACTCONTEXT AND OBJECTIVE: Studies have shown that physiopathological changes to the respiratory system can occur following thoracic and abdominal surgery. Laminectomy is considered to be a peripheral surgical procedure, but it is possible that thoracic spinal surgery exerts a greater influence on lung function. The aim of this study was to evaluate the pulmonary volumes and maximum respiratory pressures of patients undergoing cervical, thoracic or lumbar spinal surgery. DESIGN AND SETTING: Prospective study in a tertiary-level university hospital. METHODS: Sixty-three patients undergoing laminectomy due to diagnoses of tumors or herniated discs were evaluated. Vital capacity, tidal volume, minute ventilation and maximum respiratory pressures were evaluated preoperatively and on the first and second postoperative days. Possible associations between the respiratory variables and the duration of the operation, surgical diagnosis and smoking status were investigated. RESULTS: Vital capacity and maximum inspiratory pressure presented reductions on the first postoperative day (20.9% and 91.6%, respectively) for thoracic surgery (P = 0.01), and maximum expiratory pressure showed reductions on the first postoperative day in cervical surgery patients (15.3%; P = 0.004). The incidence of pulmonary complications was 3.6%. CONCLUSIONS: There were reductions in vital capacity and maximum respiratory pressures during the postoperative period in patients undergoing laminectomy. Surgery in the thoracic region was associated with greater reductions in vital capacity and maximum inspiratory pressure, compared with cervical and lumbar surgery. Thus, surgical manipulation of the thoracic region appears to have more influence on pulmonary function and respiratory muscle action.RESUMO CONTEXTO E OBJETIVO: Estudos têm demonstrado que alterações fisiopatológicas no sistema respirató-rio podem ocorrer após cirurgia torácica e abdominal. A laminectomia é considerada uma cirurgia perifé-rica, mas é possível que as cirurgias de coluna torácica exerçam maior influência sobre a função pulmonar. O objetivo do estudo foi avaliar os volumes pulmonares e as pressões respiratórias máximas em pacientes submetidos a cirurgia de coluna cervical, torácica ou lombar. TIPO DE ESTUDO E LOCAL: Estudo prospectivo em hospital universitário terciário. MÉTODOS: Sessenta e três pacientes submetidos a laminectomia com diagnóstico tumor ou hérnia de disco foram avaliados. Foram avaliados, no pré-operatório, no primeiro e no segundo ...

OBJECTIVE: Duchenne muscular dystrophy (DMD) is the most common form of muscular dystrophy in children, and children with DMD die prematurely because of respiratory failure. We sought to determine the efficacy and safety of yoga breathing exercises, as well as the effects of those exercises on respiratory function, in such children. METHODS: This was a prospective open-label study of patients with a confirmed diagnosis of DMD, recruited from among those followed at the neurology outpatient clinic of a university hospital in the city of São Paulo, Brazil. Participants were taught how to perform hatha yoga breathing exercises and were instructed to perform the exercises three times a day for 10 months. RESULTS: Of the 76 patients who entered the study, 35 dropped out and 15 were unable to perform the breathing exercises, 26 having therefore completed the study (mean age, 9.5 ± 2.3 years; body mass index, 18.2 ± 3.8 kg/m2). The yoga breathing exercises resulted in a significant increase in FVC (% of predicted: 82.3 ± 18.6% at baseline vs. 90.3 ± 22.5% at 10 months later; p = 0.02) and FEV1 (% of predicted: 83.8 ± 16.6% at baseline vs. 90.1 ± 17.4% at 10 months later; p = 0.04). CONCLUSIONS: Yoga breathing exercises can improve pulmonary function in patients with DMD.
