AB  - Introduction: Patients undergoing open bariatric surgery 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 respiratory muscle strength in obese women undergoing open bariatric surgery.Methods: This study is a randomized controlled trial. Thirty-two obese women (35.44±8.75 years and 41.78±3.84 kg/m2), undergoing elective open bariatric surgery were randomly assigned to receive preoperative inspiratory muscle training (IMT group) (n=15) or usual care (UC group) (n=17) 2-4 weeks before the surgery. The respiratory muscle strength was carried out by using measurement the Maximal Inspiratory and Expiratory Pressures – MIP and MEP. The patients were assessed before training, before surgery and 1 day after surgery.Results: After training, there was an increase in the MIP only in the IMT group (IMT= 93.33±23.80 to 120±20.35 vs UC= 92.94±18.63 to 91.76±20.38 cmH2O - p<0.05). The MEP was not altered by training. In the first postoperative day, there was a significant decrease in MIP in both the groups. However, the MIP was higher in the IMT group (IMT = 63.34±21.60 vs UC= 48.82±19.32 cmH2O – p<0.05). The MEP was similar between the groups (IMT = 49.66±22.71 vs UC = 49.70±22.39 cmH2O).Conclusion: The preoperative IMT increased the inspiratory muscle strength (MIP) and attenuated the negative postoperative effects of open bariatric surgery in obese women for this variable, though not influencing the MEP.
