Abstract

Early mobilization applied after bariatric surgery
aims to reduce postoperative complications. Notably, there is
no consensus on the appropriate time to start it. This study
aimed to analyze the recovery of lung function and length
of stay in patients undergoing bariatric surgery at different
mobilization times. Quasi-experimental, interventional study with 167 patients divided into three groups: the first 55 patients
began early mobilization 6 hours after surgery (G6); other 55
patients started after 4 hours (G4) and the last 57 patients started
after 2 hours (G2). Spirometry was performed preoperatively and
before mobilization, the measurements obtained were forced
expiratory volume in the first second (FEV1), forced vital capacity
(FVC), peak expiratory flow (PEF), maximum voluntary ventilation
(MVV) and forced expiratory flow by 25–75% (FEF25–75%). There
was a prevalence of females (82.04%), hospitalization time was
shorter in G2 (p<0.050) and vital signs remained at physiological
values. There was a significant reduction in FEV1, FVC, MVV, FEF25-
75% and PEF values in the immediately after surgery, followed by
a gradual increase (p≤0.05) as the days progressed. This study
identified that the physiotherapeutic protocol initiated 2, 4 or 6
hours after surgery was effective regarding hemodynamic stability,
reduction of hospitalization time and recovery of lung function
over time in patients undergoing bariatric surgery. However, no
difference was observed r
