“…They showed that, for women, age and body mass had a negative influence on measures of maximum respiratory pressures; however, it is worth noting that the BMI of the studied population was Ͻ30 kg/m 2 . Pazzianotto-Forti et al 14 evaluated the behavior of respiratory muscle strength in morbidly obese individuals using 3 different predictive equations and found 3 different results (predicted values) for the same value obtained. This suggests that the existing equations in the literature are not able to provide a reliable prediction of respiratory muscle strength for the morbidly obese and justifies the inconclusive results found in the literature on respiratory muscle strength in this population.…”

BACKGROUND:The objective of the present study was to develop predictive equations for maximum respiratory pressures in women according to anthropometric characteristics. METHODS: This cross-sectional study included 156 women between ages 25 and 65 y with a body mass index (BMI) between 18.5 and 55 kg/m 2 , who were evaluated for body mass, height, BMI, neck circumference, waist circumference, hip circumference, and waist/hip ratio. Respiratory muscle strength was assessed by measuring the maximum inspiratory pressure (P Imax ) and maximum expiratory pressure (P Emax ) with an analog vacuum manometer. For statistical analysis, the KolmogorovSmirnov test, Spearman correlation test, and stepwise multiple regression were used. The level of statistical significance was set at 5% (P < .05). RESULTS: Body mass, BMI, neck circumference, waist circumference, hip circumference, and waist/hip ratio showed significant and positive correlations with P Imax and P Emax . On the other hand, age and height showed no significant correlations with P Imax and P Emax . In the regression analysis, the variables that correlated significantly with P Imax and P Emax were used. CONCLUSIONS: Body mass was the variable that best contributed to predicting maximum respiratory pressures values in women (11.70% of the variations of the P Imax and 21.05% of the variations of the P Emax ). For P Imax measurements, the equation ؊0.2 ؋ body mass ؊ 65.6 was established, and for P Emax , the equation 0.3 ؋ body mass ؉ 66.4 was used. It is suggested that the predictive equations developed in this study can be used in the interpretation of the assessment of respiratory muscle strength in morbidly obese women 25-65 y of age.

“…Embora a influência da obesidade sobre as PRM seja controversa, argumentase que a restrição da cavidade torácica causada pela deposição excessiva de gordura na região toracoabdominal altera a mobilidade dos músculos abdominais e diafragmáticos, causando aumento do trabalho respiratório e consequente desvantagem muscular, o que justificar a diminuição das PRM [20,21]. Entretanto, apesar dessa linha de raciocínio, as equações preditivas mais utilizadas na literatura brasileira não incluem variáveis antropométricas como peso ou IMC e, portanto, não contemplam de forma confiável a avaliação para populações não eutróficas [13]. Uma revisão sistemática publicada em 2014 sobre a avaliação da PImáx já discutiu a [23].…”

“…Entretanto, a análise da força muscular respiratória através da pressão inspiratória máxima (PImáx) e da pressão expiratória máxima (PEmáx) em obesos tem provocado discussões conflitantes, sem um consenso sobre seu comportamento nesse grupo [9,13], principalmente quando estudados os valores previstos pelas equações de referência. Nesse contexto, o objetivo do presente estudo foi analisar o poder preditivo das equações de referência de PMR para obesos antes e após a perda de peso por cirurgia bariátrica.…”

A obesidade é uma doença crônica e multifatorial que leva a alterações sistêmicas e é considerada um problema de saúde pública mundial. Entre as alterações respiratórias decorrentes da obesidade se discute como o ganho de peso ou a perda deste pode interferir nas pressões respiratórias máximas (PRM), não existindo consenso na literatura. Objetivo: Analisar o poder preditivo das equações de referência para PMR em obesos antes e após perda de peso. Métodos: Estudo transversal no qual foram incluídos vinte pacientes obesos dos Programas de Cirurgia Bariátrica de hospitais de referência em Manaus/Amazonas, que tiveram as PRM avaliadas por meio de manuvacuometria antes e aproximadamente um ano e meio após a cirurgia bariátrica. Resultados: O peso médio diminuiu de 138,5 ± 21,7 kg para 82,7 ± 8,2 kg após a cirurgia. As PRM foram supranormais antes da cirurgia e reduzidas após a cirurgia. Entre as equações analisadas, apenas as propostas por Sanchez et al. foram capazes de predizer os valores medidos. Conclusão: As PRM foram aumentadas nos obesos mórbidos avaliados e reduzidas após a cirurgia. As equações mais utilizadas na prática clínica brasileira parecem não ser capazes de predizer valores de PRM nessa população, sendo as mais adequadas as propostas por Sanchez et al.

“…The behavior of respiratory muscle strength in these patients is still poorly understood. It is important to assess the inspiratory and expiratory muscle strength in the preoperative and postoperative periods of bariatric surgery, since respiratory muscle dysfunction is one of the causes of pulmonary complications 11,12 . The objective of this study is to evaluate and to compare respiratory muscle strength in morbidly obese individuals undergoing bariatric surgery by the conventional and by the laparoscopic routes during hospitalization for obesity surgical treatment.…”

Introduction: surgical treatment of obesity causes important changes in respiratory mechanics. Aim: Comparatively analyze respiratory muscle strength in post bariatric patients underwent to gastric bypass by laparotomy and laparoscopy during hospital stay. Methods: observational study with a non-randomized longitudinal design, of a quantitative character. Data were collected from 60 patients with BMI 40Kg/m2, divided in laparotomy group (n=30) and laparoscopy group (n=30). Smokers, patients with previous lung diseases and those unable to perform the exam correctly were excluded. Both groups were evaluated at immediate postoperative, first and second postoperative days with manovacuometry for respiratory muscle strength and visual analogue pain scale. Results: the sample was homogeneous in age, sex and BMI. Reduction in maximal respiratory pressures was observed after surgery for those operated on by laparotomy, no return to baseline values on discharge day on the second postoperative day. This group had also more severe pain and longer operative time. There was no difference in respiratory pressure measurements after surgery in the laparoscopy group. Conclusion: conventional bariatric surgery reduces muscle strength in the postoperative period and leads to more intense pain during hospitalization when compared to the laparoscopy group.
