RAMOS, Marisa de Carvalho; AGRELLI, Taciana Freitas; CARNEIRO, Élida Mara  and  CREMA, Eduardo. Smoking doesn't limit the increase in respiratory muscle strength in patients undergoing pre-inspiratory muscle training esophagectomy. Fisioter. Pesqui. [online]. 2012, vol.19, n.1, pp.63-67. ISSN 1809-2950.

A program of muscular respiratory training to smoker patients in pre-operatory ambulatory can improve the muscle strength and the functional respiratory capacity, avoiding complications which increase the hospitalization period of the patient. The aim of this work was to evaluate the effectiveness of the inspiratory muscle training in smoker and non-smoker patients who would be submitted to a megaesophagus surgery. Seventeen patients were studied, divided into two groups: smoker (GT), composed of 10 patients (58.82%), and the non-smoker (GNT), with 7 patients (41.18%). Data analysis comparing the two groups was expressed as follows: the values of age and anthropometric measurements were compared by Student's t-test and the values of Maximal Inspiratory Pressure (MIP) and Maximal Expiratory Pressure (MEP) were compared by the paired Student's t-test. Data were expressed as mean±standard deviation when checked to normal. Differences were considered statistically significant if p<0.05. Level of significance adopted was p=0.05. Considering the comparative analysis, it was observed a significant increase of Maximal Inspiratory Pressure MIP after the 4 weeks of inspiratory muscle training (IMT), as follows: MIP in GT from -57.20±18.76 to -79.00±15.38 and in GNT from -52.00±18.76 to -72.66±19.33. The prophylactic therapy in the preoperative outpatient provides a significant increase in inspiratory muscle strength in both groups, as evidenced by the increase in MIP with consequent improvement in ventilatory capacity.
