We concluded that a 20 m corridor can be used safely and effectively as an alternative to 30 m for the 6MWT for male patients with cirrhosis on the liver transplantation waiting list.
CONTEXT AND OBJECTIVE: Noninvasive mechanical ventilation during the postoperative period (PO) following lung resection can restore residual functional capacity, improve oxygenation and spare the inspiratory muscles. The objective of this study was to assess the efficacy of continuous positive airway pressure (CPAP) associated with physiotherapy, compared with physiotherapy alone after lung resection. DESIGN AND SETTING: Open randomized clinical trial conducted in the clinical hospital of Universidade Estadual de Campinas. METHOD: Sessions were held in the immediate postoperative period (POi) and on the first and second postoperative days (PO1 and PO2), and the patients were reassessed on the discharge day. CPAP was applied for two hours and the pressure adjustment was set between 7 and 8.5 cmH 2 O. The oxygenation index (OI), Borg scale, pain scale and presence of thoracic drains and air losses were evaluated. RESULTS: There was a significant increase in the OI in the CPAP group in the POi compared to the Chest Physiotherapy (CP) group, P = 0.024. In the CP group the OI was significantly lower on PO1 (P = 0,042), than CPAP group. The air losses were significantly greater in the CPAP group in the POi and on PO1 (P = 0.001, P = 0.028), but there was no significant difference between the groups on PO2 and PO3. There was a statistically significant difference between the groups regarding the Borg scale in the POi (P < 0.001), but there were no statistically significant differences between the groups regarding the pain score. CONCLUSION: CPAP after lung resection is safe and improves oxygenation, without increasing the air losses through the drains. CLINICAL TRIAL REGISTRATION: NCT01285648RESUMO CONTEXTO E OBJETIVO: A ventilação mecânica não invasiva no período pós-operatório (PO) de ressecção pulmonar pode restaurar a capacidade residual funcional, melhorar a oxigenação e poupar os múscu-los inspiratórios. O objetivo deste estudo foi avaliar a eficácia da CPAP associada à fisioterapia comparada à fisioterapia unicamente após ressecção pulmonar. ESTUDO E LOCAL: Ensaio clínico randomizado aberto, realizado no Hospital das Clínicas da Universidade Estadual de Campinas. MÉTODO: Os atendimentos foram realizados nos PO imediato (POi), primeiro e segundo (PO1, PO2) dias, e a reavaliação na alta hospitalar. A CPAP foi aplicada durante duas horas e o ajuste pressórico estabelecido entre 7 e 8,5 cmH 2 O. Foram analisados índice de oxigenação (IO), escala de Borg e de dor, presença e perda aérea dos drenos torácicos. RESULTADOS: No grupo CPAP ocorreu aumento significativo do IO no POi (P = 0,024), comparado com o grupo fisioterapia respiratória. Houve redução significativa do IO no PO1 (P = 0,042) para o grupo fisioterapia respiratória, comparando-se à CPAP. A perda aérea foi significativamente maior para o grupo CPAP no POi e PO1 (0,001; 0,028), mas nos PO2 e no PO3 não houve diferença significativa entre os grupos. Foi verificada diferença significativa entre os grupos para a escala de Borg no POi (P < 0,001), porém...
As neoplasias pulmonares podem causar deterioração na função pulmonar e capacidade funcional, prejudicando a evolução do paciente após cirurgia de ressecção. objetivo: Avaliar a força muscular respiratória, a função pulmonar e a capacidade funcional de pacientes no pré-operatório de ressecção pulmonar por neoplasia, comparar aos valores de normalidade e por estadiamento. métodos: Foram incluídos pacientes na faixa etária de 30 a 80 anos com diagnóstico de neoplasia de pulmão que aguardavam cirurgia de ressecção pulmonar. A avaliação pré-operatória incluiu medida de força muscular respiratória por manovacuometria, função pulmonar por espirometria e capacidade funcional pelo teste de caminhada dos seis minutos (TC6). Os valores obtidos foram comparados aos valores preditos pela literatura e comparados os estadiamentos inicial e avançado. resultados: Foram avaliados 59 pacientes com idade média de 58,5±9,46 anos. Houve diferença estatisticamente significante entre obtido e predito, respectivamente, para os valores de pressão expiratória máxima (PEmáx): 91 e 111,8 cmH 2 O; capacidade vital forçada (CVF): 3,14 e 4,08 L; volume expiratório forçado no primeiro segundo (VEF 1 ): 2,42 e 3,12 L; razão VEF 1 /CVF: 75 e 101%; e capacidade funcional: 453,9 e 562,9 m, sendo que os pacientes apresentaram valores inferiores aos preditos pela literatura, exceto a CVF. Não houve diferença para a pressão inspiratória máxima (PImáx): 110 e 102 cmH 2 O. Entre os grupos de estadiamento houve diferença apenas para a CVF (inicial: 2,89; avançado: 3,41 L). Conclusão: Os pacientes com diagnóstico de neoplasia pulmonar em pré-operatório de ressecção possuem prejuízos na força muscular expiratória, na função pulmonar e na capacidade funcional.Palavras-chave: neoplasias pulmonares; espirometria; testes de função respiratória; fisioterapia.
SARS-CoV-2 infection can cause severe acute respiratory syndrome (SARS), leading to hypoxemia. Physical capacity assessment can be performed before hospital discharge using submaximal exercise testing. This study sought to assess physical capacity and exercise tolerance with the six-minute step test (6MST) in hospitalized COVID-19 patients who required oxygen (O2) support during hospitalization. A prospective, interventional study was conducted with patients aged from 18 to 90 years who required oxygen therapy during hospitalization. Assessment was performed using Perme Score, followed by the 6MST tests, assessing the peripheral oxygen saturation (SpO2), heart rate (HR), blood pressure (BP), and subjective exertion perception by Borg Scale, before and immediately after the 6MST. A total of 31 patients, with a mean age of 51.9 years, were evaluated. Nasal cannula (NC) was the most used device (64.5% of patients). Regarding HR, BP, and Borg Scale, their mean value increased after 6MST. SpO2 showed a lower mean value after 6MST. Out of the 86.9% of patients who completed the test, 48.3% completed it with interruptions, and 12.9% had to suspend it. The 6MST was able to assess physical capacity and exercise tolerance, proving to be an effective tool for evaluating COVID-19 patients.
