Objective: To evaluate the effect of the association of the breath stacking (BS) technique associated with routine physiotherapy on pulmonary function, lung volumes, maximum respiratory pressures, vital signs, peripheral oxygenation, thoracoabdominal mobility, and pain in the surgical incision in patients submitted to upper abdominal surgery during the postoperative period, as well as to analyze BS safety. Methods: This was a randomized clinical trial involving 34 patients divided into a control group (CG; n = 16), who underwent conventional physiotherapy only, and the BS group (BSG; n = 18), who underwent conventional physiotherapy and BS. Both groups performed two daily sessions from postoperative day 2 until hospital discharge. The primary outcomes were FVC and Vt. The safety of BS was assessed by the incidence of gastrointestinal, hemodynamic, and respiratory repercussions. Results: Although FVC significantly increased at hospital discharge in both groups, the effect was greater on the BSG. Significant increases in FEV1 , FEV1 /FVC ratio, PEF, and FEF25-75% occurred only in the BSG. There were also significant increases in Ve and Vt in the BSG, but not when compared with the CG values at discharge. MIP and MEP significantly increased in both groups, with a greater effect on the BSG. There was a significant decrease in RR, as well as a significant increase in SpO2 only in the BSG. SpO2 acutely increased after BS; however, no changes were observed in the degree of dyspnea, vital signs, or signs of respiratory distress, and no gastrointestinal and hemodynamic repercussions were observed. Conclusions: BS has proven to be safe and effective for recovering pulmonary function; improving lung volumes, maximum respiratory pressures, and peripheral oxygenation; and reducing respiratory work during the postoperative period after upper abdominal surgery.

The aim of this study was to evaluate the influence of physical exercise on the levels of oxidative stress in cardiac tissue after the inhalation of cigarette smoke in rats. Rats were divided into four groups: (a) non-smokers + non-exercised (NS+NE); (b) non-smokers + exercised (NS+E); (c) smokers + non-exercised (S+NE); and (d) smokers + exercised (S+E). The cigarette smoke was inhaled during 30 min, twice a day, and then extended to 10 cigarettes for 30 min twice a day. Physical exercise was performed on a treadmill. The initial velocity was 10 m·min-1 increasing up to the mark of 30 m·min-1. Cardiac tissue lipoperoxidation (LPO) estimation was performed using the TBARS method. The values were expressed in levels of malondialdehyde (MDA), and enzymatic antioxidant defense was measured by catalase (CAT) activity. These findings indicate that the physical exercise induced lower levels of LPO and increased CAT activity, which attenuated the oxidative stress induced by exposure to cigarette smoke.

Background: Functional electrical stimulation (FES) has shown benefits in patients with chronic heart failure. Therefore, it is possible that FES can benefit patients similarly after cardiac surgery. Objective: This randomized placebo-controlled trial aimed to evaluate the effects of FES on lower limb functional capacity, strength, endurance, and muscle mass after discharge from cardiac surgery. Methods: Twenty patients were allocated (1:1) to the group receiving FES to the quadriceps (FESG) or FES placebo (FESPG). FES was applied at a frequency of 15 Hz, with 0.5 ms pulse width, 5 s contraction time, and 10 s resting time, twice a week for 40 min over a period of eight weeks. Functional capacity was assessed using the six-minute walk test (6MWT), lower limb muscle strength using the one repetition maximum test (1RM), endurance using the sit-and-stand test (SST), and muscle using the perimeter of the thighs. Results: Both groups increased the distance covered in the 6MWT (FESG: 49.6 m, 95% CI 15.9-83.3; FESPG: 41.5 m, 95% CI 7.8-75.2), but without a difference between groups. There were significant between-group differences for quadriceps muscle strength (7.2 kg, 95% CI 0.2-14.2) and muscle endurance (2.2 repetitions, 95% CI 1.0-3.4) in favor of the FESG. Conclusion: FES improves lower limb muscle strength and endurance in patients after cardiac surgery. Larger trials are needed to confirm our findings. [ABSTRACT FROM AUTHOR]
