PHYSIOTHERAPEUTIC APPROACHES AND THE EFFECTS ON INSPIRATORY MUSCLE FORCE IN PATIENTS WITH CHRONIC OBSTRUCTIVE PULMONARY DISEASE IN THE PRE-OPERATIVE PREPARATION FOR ABDOMINAL SURGICAL PROCEDURES.

BACKGROUND: Abdominal disorders can alter respiratory function and increase the morbidity and mortality of patients with chronic obstructive pulmonary disease. AIM: To improve the physiotherapeutic and muscular capacity in chronic obstructive pulmonary muscular inspiration in the preoperative preparation in abdominal surgeries. METHOD: Retrospective and documentary study using SINPE © , clinical database software of patients with chronic obstructive pulmonary disease and candidates to abdominal operation. The sample consisted of 100 men aged 55-70 years, all with chronic obstructive pulmonary disease who underwent preoperative physiotherapeutic treatment. They were divided into two groups of 50 individuals (group A and group B). In group A the patients were treated with modern mobility techniques for bronchial clearance and the strengthening of the respiratory muscles was performed with IMT ® Threshold. In group B the treatment performed for bronchial obstruction was with classic maneuvers and for the strengthening of the respiratory muscles for flow incentive was used Respiron ® . RESULTS: Both groups obtained improvement in the values ​​of the PiMáx after the different treatments. Group A obtained greater change in the intervals and a more significant increase of the values of the PiMax in relation to the average pre and post-treatment. However, when analyzing the variance and the standard deviation of the samples, group B presented the best results showing more homogeneity. CONCLUSIONS: The modern and traditional bronchial clearance techniques associated with inspiratory muscle training were equally effective in gaining inspiratory muscle strength with increased Pmax. In this way, the two can be used in the preoperative preparation of patients with chronic obstructive pulmonary disease and referred to abdominal operations.

RESUMO Racional: As operações abdominais podem alterar a função respiratória e aumentar a morbimortalidade dos operados com doença pulmonar obstrutiva crônica. Objetivo: Avaliar que técnica fisioterapêutica apresenta melhor efeito na força muscular inspiratória dos pacientes com doença pulmonar obstrutiva crônica no preparo pré-operatório em operações abdominais. Método: Estudo retrospectivo e documental usando o SINPE©, software de banco de dados clínicos de pacientes portadores de doença pulmonar obstrutiva crônica e candidatos a operações abdominais. A amostra foi composta de 100 homens com idade entre 55-70 anos, todos com DPOC com indicação para operação abdominal e que realizaram tratamento fisioterapêutico pré-operatório. Foram divididos em dois grupos de 50 indivíduos (grupo A e grupo B). No grupo A o tratamento realizado para a desobstrução brônquica foi com técnicas modernas e para fortalecimento dos músculos respiratórios foi realizado o Threshold IMT®. No grupo B o tratamento realizado para desobstrução brônquica foi com técnicas tradicionais e para fortalecimento dos músculos respiratórios foi realizado incentivador a fluxo Respiron®. Resultados: Ambos os grupos obtiveram melhora dos valores da PiMáx (Pressão inspiratória Máxima) após o tratamento com abordagens diferentes com melhora também nos intervalos da PiMáx. O grupo A obteve maior mudança nos intervalos e aumento mais significativo dos valores da PiMáx em relação à média pré e pós tratamento. Porém, ao analisar a variância e o desvio-padrão das amostras, o grupo B apresentou melhor distribuição que o grupo A mostrando que seus resultados na amostra foram mais homogêneos. Conclusões: As técnicas modernas e tradicionais de desobstrução brônquica associadas ao treinamento muscular inspiratório mostraram-se igualmente eficazes no ganho de força dos músculos inspiratórios com aumento da PiMáx. Dessa forma as duas podem ser utilizadas no preparo pré-operatório de pacientes com DPOC e encaminhados para operações abdominais.
