Comparação entre exercícios de respiração profunda e espirometria de incentivo no pós-operatório de cirurgia de revascularização do miocárdio

Abstract

Objective: To compare the effects of deep breathing exercises (DBE) and the flow-oriented incentive spirometry (IS) in patients undergone coronary artery bypass grafting (CABG) through the following variables: forced vital capacity -FVC, forced expiratory volume in 1 second -FEV 1 , maximal respiratory pressures and oxygen saturation.Methods: Thirty six patients in CABG postoperative period underwent thirty minutes of non-invasive ventilation during the first 24 hours after extubation and were randomly shared into two groups as following: DBE (n=18) and IS (n=18). The spirometric variables were assessed on the preoperative period and seventh postoperative day (POD). The respiratory muscle strength and oxygen saturation were assessed on the preoperative period, first, second and seventh POD.Results: The groups were considered homogeneous in relation to the demographic and surgical variables. It has been noted fall in the values of FVC and FEV 1 between the preoperative period and the seventh POD, but without significant differences between groups. The maximal respiratory pressures showed drop in the first POD but with gradual and partial recovery until the seventh POD, also without significant differences between groups. The oxygen saturation was the only variable that was completely recovered on the seventh POD, also without significant differences between groups.Conclusion: There were not observed significant differences in maximal respiratory pressures, spirometric variables and oxygen saturation in patients undergone deep breathing exercises and flow-oriented incentive spirometry after coronary artery bypass grafting.

Repercussão de um protocolo fisioterapêutico intradialítico na funcionalidade pulmonar, força de preensão manual e qualidade de vida de pacientes renais crônicos

“…In addition, training of the respiratory muscles provides greater capacity to physical exercise and greater tolerance to fatigue. 33 Renault et al (2009) 34 have compared the effects of Exercises of Diaphragmatic Breathing (EDB) and Incentive Spirometer (IS) in patients undergoing coronary artery bypass grafting surgery by using the following variables: forced vital capacity; first-second forced expiratory volume, maximal respiratory pressures, and oxygen saturation. Those authors have reported no significant differences in the respiratory variables studied in patients undergoing EDB and IS in the post-operative period of coronary artery bypass grafting surgery.…”

Recrutamento alveolar em pacientes no pós-operatório imediato de cirurgia cardíaca

“…The technique involves the application of CPAP with pressure levels ranging from 30 to 45 cmH2O pulmonary complications after cardiac surgery [5,6]. When approaching these cases, respiratory physiotherapy has been increasingly requested, since it uses techniques that can improve respiratory mechanics, reexpansion pulmonary and bronchial hygiene.…”

Efeitos do exercício muscular respiratório na biomecânica da deglutição de indivíduos normais

“…Among these, we can highlight the Respiron® IS, which emphasizes the deep inspiration up to total lung capacity, providing visual feedback 7,8 . This type of IS facilitates deep breathing, stimulates high inspired volumes and prevents lung hypoventilation 6,9,10 .…”
