['Are oxygenation and static compliance improved immediately after manual hyperinflation following myocardial revascularisation? Does this lead to earlier extubation and shorter hospital stay? Does it reduce postoperative pulmonary complications?', 'Randomised controlled trial with concealed allocation, blinded assessment and intention-to-treat analysis.', 'Fifty-five patients who underwent myocardial revascularisation.', 'After an hour in recovery, the experimental group received manual hyperinflation with positive end expiratory pressure followed by suction while the control group received suction only.', 'Oxygenation (PaO(2) in mmHg) and static lung compliance (in ml/cmH(2)O) were measured immediately after suction. Time to extubation (in minutes) and length of hospital stay (in days) were collected and postoperative pulmonary complications were confirmed by X-ray.', 'PaO(2) was 11.7 mmHg (95% CI 9.4 to 14.0) greater in the experimental group while static compliance was 8.5 ml/cmH(2)0 (95% CI 6.4 to 10.6) greater than in the control group. The experimental group was extubated 76 minutes (95% CI 24 to 128) earlier than the control group but did not have a shorter length of stay (mean difference 0.5 days, 95% CI -0.2 to 1.2). The relative risk of postoperative pulmonary complications was no greater (RR 0.57, 95% Cl 0.20 to 1.60) in the experimental group than in the control group.'] Is oxygenation and static compliance improved immediately after early manual hyperinflation following myocardial revascularisation : a randomised controlled trial?
