Randomized Controlled Trial Clinical TrialPre-operative short-term pulmonary rehabilitation for patients of chronic obstructive pulmonary disease undergoing coronary artery bypass graft surgery.
The role of pre-operative short-term pulmonary rehabilitation in patients with chronic obstructive pulmonary disease who undergo coronary artery bypass graft surgery has been assessed for the first time prospectively. Forty-five patients posted for coronary artery bypass graft surgery were randomised to receive either short-term pulmonary rehabilitation (group I) or no such programme (group II). Patients of both the groups were evenly matched with respect to age, sex, body surface area, duration and severity of chronic obstructive pulmonary disease and coronary artery disease. ⋯ Even though both groups showed a significant rise in post-operative peak expiratory flow rate and inspiratory capacity after surgery, the post-operative peak expiratory flow rate and inspiratory capacity in group I was significantly higher than in group II. In group I, the post-operative ventilation time (24.5 +/- 6.00 hours), post-operative complications (n = 4) and hospital stay (12.4 +/- 3.6 days) were significantly lower than in group II (35.2 +/- 22.3 hours, n = 11, 18.8 +/- 6.6 days respectively). These data suggest that short-term pulmonary rehabilitation is feasible and effective in improving pulmonary functions before and after surgery and in reducing surgical morbidity and cost of medical care significantly.
