Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Post-surgery patients have muscle impairments, especially in the respiratory muscles, because the anesthesia, surgical incision, mechanical ventilation, pain, and prolonged postures, affect the mechanical condition of respiratory muscles. Those consequences produce a low exercise tolerance and low quality of life. These patients must go to cardiac rehabilitation to improve heart functions; however, these patients have a weakness in their respiratory muscles. Currently, there are many devices for respiratory muscle strength, although these devices are expensive, and they only have one circuit for training (inspiratory or expiratory). Triburter is a new device with two valves and positive pressure generation, this is a promising alternative because Triburter improves the mechanics of ventilation, increasing their functionality and quality of life. For this reason, the main hypothesis is that respiratory muscle training with Triburter improves the strength of inspiratory and expiratory muscles.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Aim and objectives: The aim of this study is to determine the efficacy of the Triburter device in comparison with usual therapy (incentive spirometer), as a therapeutic element in respiratory therapy on respiratory muscle function in patients with cardiovascular surgery who will join the second phase of the cardiac rehabilitation program of Fundación Cardiovascular de Colombia. And the specific objectives will be to evaluate the magnitude of change of maximal inspiratory pressure and maximal expiratory pressure, lung function (spirometry), functional capability (6MWT), quality of life (SF-36) and identify the adverse events related to the use of Triburter or incentive Methods design: The design of the pilot study is a randomized clinical trial, open with a control group.

Sample: Following the recommendations to elaborate a pilot trial with feasibility and precision, the recruitment will count 30 patients with no probabilistic sample (intentional sample) Data collection: Personal information forms and case report forms are prepared by principal research after a literature review about relevant variables to collect in the study. CRF included questions regarding socio-economic variables, hospitalized factors, body mass index, heart rate, respiratory rate, and temperature. Then the patients were evaluated in aspects of muscle strength, lung function, functional capacity, and quality of life. The informed consent was obtained from all the patients. The purpose of the study was explained to each patient.

Statistical analyses Firstly, descriptive variables will express in the median and standard deviation for the numeric variables, and for the categoric variables will express in absolute value and percent. A bivariate analysis will be used to determine differences in intergroup through t - Test o Chi-square or U Mann Whitney as appropriate for the type of distribution. The use of crosstabs and categorization of dependent variables to define corresponding patients (with improvement on measures applied) to difference to each group. Correlations will search between clinical variables, functionality, and quality of life through bivariate analysis (spearman) and multivariate (logistic regression) To measure the change induced by training in the functional variables. the researchers will use the analysis of the change of percent \[(value pos intervention - value pre/value pre)\*100\]. To compare the quantitative variables in the two situations (pre-post) and the same group, researchers will use the test of t student for the pair data, and multilevel analysis adjusted by each patient and analyzed by each intervention.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

Participants will be randomized into two groups by a randomization list provided by a computer program. The intervention group will receive a triburter device for training, the patients will have to repeat 50 ventilations (start with 20 repetitions in the first week, 30 in the second, 40 in the four week, and 50 in the last week) five days per day. For the control group (incentive spirometry) they will repeat 10 ventilations per 5 five times a day. Both interventions will be performed for 4 weeks.
