Cycle-ergometer in the Postoperative of Thoracic Surgery

Summary

Post-lateral thoracotomies and assisted thoracic surgery (CTVA) are the main surgical approaches for pulmonary resections. One of the counterpoints of these surgical approaches is postoperative pain, which in addition to causing ventilatory changes and reduction of lung capacities, contributes to bed rest and consequent decrease in patients' functionality. These complications increase hospitalization time and hospital costs, being determinant factors for perioperative morbidity and mortality. In order to prevent these outcomes of reduce the functional capacity of patients, new physiotherapeutic approaches have been adopted, such as the use of the cycloergometer. Recent studies show that the early use of this device brings benefits such as: improved blood circulation and venous return, increased muscle strength, improved functional capacity and reduced symptoms of dyspnea and fatigue. This study aims to compare the effect of interval training with continuous cycle ergometer training on performance in the six-minute walk test. Randomized and controlled clinical trial performed with patients submitted to elective thoracic surgery, hospitalized at the intensive care unit (ICU) and in the hospitalization unit of the Hospital Pavilhão Pereira Filho of the Santa Casa de Misericórdia Brotherhood of Porto Alegre. Participants will be randomized into three groups: control group (CG), interval exercise group (GHG) and continuous exercise group (GEC). Functional capacity assessments will be performed through the six-minute walk test (6MWT) and the chair sit and lift (TSL) test in 30 seconds, and evaluation of the clinical state of fatigue through the revised Piper-Fatigue Scale. The evaluations will be performed preoperatively and at hospital discharge.

• Dyspnea
• Muscle Strength

Interventions

OTHER

Interval effort group

Pre-surgical evaluations (Six-minute walk test, sit and lift test 30 in seconds, and Piper fatigue scale) Active phase (high load) lasting 60 seconds, followed by an active recovery phase with light / moderate load (60% of the maximum load) lasting 4 minutes. The pedaling speed should be maintained between 30-60rpm. There will be 5 cycles that will total 20 minutes of physical effort, and assessments at discharge.

OTHER

Continuous effort group

Pre-surgical evaluations (Six-minute walk test, sit and lift test 30 in seconds, and Piper fatigue scale) Intensity used will be mild / moderate, ie 60% of the maximum load reached in the incremental test. The pedaling speed should be maintained between 30-60rpm. The execution time, from this exercise regime will be 20 minutes, and assessments at discharge.
