“…This procedure was validated according to the MIP, presenting accuracy and good correlation, involving reduced risk of fatigue due to staying for less time at the pressure peak, as well as an easier and more physiological execution [43]. In addition to promoting greater comfort, these advantages should be considered when performing it on post-operative patients [44], as in this study. According to Siafakas et al [2], the decrease in NIP identifies the muscle inefficiency promoted by inherent factors of the surgical procedure, as previously described.…”

Licensed under a Creative Commons attribution ORIGINAL ARTICLE Inspiratory loading exercises on respiratory muscle function in post-operative gastroplasty patients: a randomized clinical trialExercícios com carga inspiratória na função muscular respiratória no pós-operatório de gastroplastia: um ensaio clínico randomizado Ejercicios con carga inspiratoria en la función muscular respiratoria en el postoperatorio de gastroplastia: un ensayo clínico aleatorizado Abstract Introduction: The gastroplasty post-operative period can alter respiratory mechanics and predispose patients to respiratory complications. Objective: The objective was to evaluate the effects of exercises with inspiratory load on respiratory muscle function and on the prevalence of atelectasis after gastroplasty. Method: 40 participants were randomly allocated into two groups: Control Group (CG), its members underwent conventional respiratory physical therapy (CRP) and the Inspiratory Load Group (ILG), its members performed exercises with linear inspiratory pressure load, with 40% of the maximum inspiratory pressure (MIP), associated with CRP. Therapy procedures were conducted twice during the immediate post-operative period and thrice on the first postoperative day. In addition to evaluating the MIP, the nasal inspiratory pressure (NIP) and the sustained maximum inspiratory pressure (SMIP) were evaluated before and after treatment. Analysis of variance followed by the Bonferroni correction were applied considering a 5% significance level (p < 0.05). Results: There was no significant difference in NIP and SMIP values when the pre-and post-operative periods were compared for the ILG; however, these values were significantly lower for the CG, also with intergroup differences in NIP values. Atelectasis prevalence was 5% for ILG and 15% for CG, with no intergroup difference. Conclusion: The inspiratory muscle strength and resistance of the respiratory muscles were maintained in the group that performed exercises with inspiratory load associated with CRP, with a low rate of atelectasis after gastroplasty. Introdução: O pós-operatório de gastroplastia pode alterar a mecânica respiratória e predispor a complicações respiratórias. Objetivo: Avaliar os efeitos de exercícios com carga inspiratória na função muscular respiratória e na prevalência de atelectasias após gastroplastia. Método: 40 voluntárias foram alocadas randomicamente em: Grupo Controle (GC), que recebeu Fisioterapia Respiratória Convencional (FRC) e Grupo Carga Inspiratória (GCI), que executou exercícios com carga inspiratória linear pressórica com 40% da pressão inspiratória máxima (PImáx), associados à FRC. Os tratamentos foram realizados duas vezes no pós-operatório imediato e três vezes no primeiro dia pós-operatório. Além da PImáx, foram avaliadas a pressão inspiratória nasal (PIN) e a pressão inspiratória máxima sustentada (PImáxS) antes e após o tratamento. Foi realizada análise de variância seguida de ajuste deBonferroni, e o nível de significância estatística foi de 5% (p < 0,05). Res...

“…Ten maneuvers were requested 21 , with an interval of 30 s between each one, using as the criterion for selection of the acceptable Sniff, generation of the highest pressure peak and duration between 0-5 s 30 . It is a validated technique, with accuracy and high correlation with MIP, being considered its more physiological execution 27 besides promoting greater comfort, benefits that should be considered in postoperative patients 15 .…”

Background: Bariatric surgery can trigger postoperative pulmonary complications due to factors inherent to the procedure, mainly due to diaphragmatic dysfunction. Aim: To evaluate and compare the effects of two levels of positive pressure and exercises with inspiratory load on lung function, inspiratory muscle strength and respiratory muscle resistance, and the prevalence of atelectasis after gastroplasty. Methods: Clinical, randomized and blind trial, with subjects submitted to bariatric surgery, allocated to two groups: positive pressure group, who received positive pressure at two levels during one hour and conventional respiratory physiotherapy and inspiratory load group, who performed exercises with load linear inspiratory pressure, six sets of 15 repetitions, in addition to conventional respiratory physiotherapy, both of which were applied twice in the immediate postoperative period and three times a day on the first postoperative day. Spirometry was performed for pulmonary function analysis, nasal inspiratory pressure for inspiratory muscle strength and incremental test of respiratory muscle resistance for sustained maximal inspiratory pressure, both preoperatively and on hospital discharge on the second postoperative day. Results: There was no significant difference (p> 0.05) in the expiratory reserve volume and in the tidal volume in the pre and postoperative periods when compared intra and intergroup. There was no significant difference (p>0.05) in the nasal inspiratory pressure and the maximal inspiratory pressure maintained in the inspiratory load group in the intragroup evaluation, but with a significant difference (p<0.05) compared to the positive pressure group. The prevalence of atelectasis was 5% in both groups with no significant difference (p>0.05) between them. Conclusion: Both groups, associated with conventional respiratory physiotherapy, preserved expiratory reserve volume and tidal volume and had a low atelectasis rate. The inspiratory loading group still maintained inspiratory muscle strength and resistance of respiratory muscles.

According to a previous study (Graetz et al, 2012), 19 we calculated that a sample size constituting 24 subjects (12 per group) was required to obtain 80% power with an effect size of 1.074628, type I error (a) ¼ 0.05 and type II error (b) ¼ 0.20.…”

Objective We aimed to compare functional exercise capacity, respiratory and peripheral muscle strength, pulmonary function and quality of life between patients with stable angina and healthy controls. Methods We compared 33 patients with stable angina (55.21 ± 6.12 years old, Canada Class II–III, left ventricular ejection fraction: 61.92 ± 7.55) and 30 healthy controls (52.70 ± 4.22 years old). Functional capacity (6-minute walk test (6-MWT)), respiratory muscle strength (mouth pressure device), peripheral muscle strength (dynamometer), pulmonary function (spirometer) and quality of life (Short Form 36 (SF-36)) were evaluated. Results 6-MWT distance (499.20 ± 51.91 m versus 633.05 ± 57.62 m), maximal inspiratory pressure (85.42 ± 20.52 cmH2O versus 110.44 ± 32.95 cmH2O), maximal expiratory pressure (83.33 ± 19.05 cmH2O versus 147.96 ± 54.80 cmH2O) and peripheral muscle strength, pulmonary function and SF-36 sub-scores were lower in the angina group versus the healthy controls, respectively. Conclusion Impaired peripheral and respiratory muscle strength, reduction in exercise capacity and quality of life are obvious in patients with stable angina. Therefore, these parameters should be considered in stable angina physiotherapy programmes to improve impairments.
