The aim of this study was to establish whether removal of breathing exercises from a regimen including early mobilisation changes the incidence of post-operative pulmonary complications for patients after cardiac surgery. Two hundred and thirty patients undergoing open heart surgery at Monash Medical Centre, Melbourne, were enrolled in this randomised controlled trial. All patients received physiotherapy treatment pre-operatively and post-operatively for three days. Patients were mobilised as soon as possible after surgery. Breathing group (control) patients performed a set routine of deep breathing exercises at each physiotherapy visit while those in the intervention group did not perform this routine. Other than the breathing exercises, patient management was similar between groups in terms of assessment, positioning and mobility. The incidence of postoperative pulmonary complications, post-operative length of stay, oxyhaemoglobin saturation and pulmonary function were measured pre-operatively and post-operatively. Intention-to-treat analysis was performed for post-operative pulmonary complications and length of stay. Other data were analysed using t-tests, chi square and repeated measures analysis of variance. There were no significant differences between the groups in the primary dependent variables. It is concluded that removal of breathing exercises from the routine physiotherapy management of open heart surgery patients does not significantly alter patient outcome.
We present a non-surgical treatment option to decrease symptoms of dyspnea in a 6 year-old child with congenital bilateral abductor vocal fold paralysis. A respiratory muscle strength-training program was used to strengthen her inspiratory muscles for 8 months, 3 to 5 days per week. Inspiratory muscle strength increased over the course of training, resulting in reported decreases in dyspnea by both the child and parents during speech and exercise.
In this review we shall consider the commonest techniques to reduce dyspnea that are being applied to patients with chronic obstructive pulmonary disease (COPD) subjected to a pulmonary rehabilitation program (PRP). Pursed lip breathing (PLB) and diaphragmatic breathing (DB) are breathing retraining strategies employed by COPD patients in order to relieve and control dyspnea. However, the effectiveness of PLB in reducing dyspnoea is controversial. Moreover, DB may be associated with asynchronous and paradoxical breathing movements, reflecting a decrease in the efficiency ofthe diaphragm. Exercise training (EXT) is a mandatory component of PRP.EXT has been shown to improve exercise performances and peripheral muscle strength. Recent studies have focused on the effect of EXT on breathlessness. However, concerns persist as to whether the decreased sensation of dyspnea for a given exercise stimulus is principally due to psychological benefits of rehabilitation or to improved physiological ability to perform exercise. The effect of EXT on breathlessness may be reinforced by inhaling oxygen. However, two studies have recently shown that breathing supplemental oxygen during training has either a marginal effect or no advantage over training. In a comprehensive PRP, strength training (ST) and arm endurance training (AET) could have a role in decreasing peripheral muscle weakness and metabolic and ventilatory requirements for AET. The role of unloading the respiratory muscles during EXT has to be
