Respiratory Muscle Training using the Novel Multifunctional Respiratory Device during the Mid-postoperative Period following Cardiac Surgery: A Real-Life Pilot Study.

Respiratory muscle(RM) weakness increases the risk of complications, hospitality length of stay, and mortality of patients in the postoperative period for cardiac surgery. Nevertheless, RM dysfunction can be potentially reversed using RM training. We developed and patented an innovative device(TriBURTER®) incorporating 5 effects, allowing simultaneously to train inspiratory and expiratory muscles, provide vibratile waves to mobilize secretions and to stimulate cough, and incentivize respiratory movements. To compare with a flow-incentive spirometer(IS) the efficacy of(TriBURTER) to increase the respiratory muscle strength as an additional strategy to cardiac rehabilitation phase II. A randomized(1:1) study was performed. Thirty adult patients(63±9 yrs, 13.3% women) were submitted to daily RM training sessions additional to cardiac rehabilitation program. Training for 4 weeks with (TriBURTER®) or IS. The main outcomes were the maximum pressures measured in the mouth (PImax, PEmax) at 1, 14, and 28 days. The groups were comparable in demographic, anthropometric, and functional baseline variables. Both groups disclosed improvements in PImax and PEmax(p<0,05). Nevertheless, weak patients showed greater improvements in PImax(p=0.001) and PEmax(p=0.0313) in the intervention group. The added value when compared with IS group was +40% for PImax and +28% for PEmax. (TriBURTER®) represents a Colombian innovative device allowing to effectively and safely to increase fastly and greater proportion the inspiratory and expiratory muscle strength. TriBURTER provides additional valuable effects that are not offered using the conventional IS.
