Abstract
Introduction: Patients undergoing open bariatric surgery (OBS) have an impaired lung function in the postoperative period. Aiming to attenuate these negative effects, the preoperative IMT may be an alternative.
Objective: To determine whether preoperative IMT is able to attenuate the impact of surgical trauma on the diaphragmatic excursion in obese women undergoing OBS.
Methods: Thirty-two obese women (35.44±8.75 years and 41.78±3.84 kg/m2), undergoing elective OBS were randomly assigned to receive preoperative IMT (IMT group) (n=15) or usual care (Control group - CG) (n=17) 2-4 weeks before the surgery. The diaphragmatic excursion was evaluated using the digitalized image of the radiograph. The area was calculated of the right and the left dome of the diaphragm. The patients were assessed before and after training, and 1 day after surgery.
Results: The diaphragmatic excursion of the right and the left dome were not altered by training. In the first postoperative day, there was a significant decrease in both groups. However, the values of diaphragmatic excursion were higher in the IMT group, even though they were not statistically significant.

Conclusion: The preoperative IMT appears to attenuate the negative postoperative effects of open bariatric surgery in diaphragmatic excursion.
