Abstract

Objective: The objective of this study is to determine the predominant spirometric pattern in patients with chronic airflow obstruction (CAO) due to pulmonary tuberculosis (PTB) sequelae (CAO-PTB) in family health center of La Florida, Talca.
Methods: Descriptive study of 17 patients (5 men, 12 women), with a mean age ± SD of 72•8 ± 8•4 years, with a CAO-PTB diagnostic, who underwent a basal and post bronchodilator spirometry. The measured variables were: basal and post bronchodilator FEV1/FVC, FEV1, FVC, FEF 25-75%, and change in FEV1 and FVC, measured in percentage and ml. The statistical analysis was made using the software SPSS, version 23.
Results: Of the 17 evaluated patients, 13 showed an obstructive spirometric pattern (76•5%), 3 a normal spirometric pattern (17•6%) and 1 a restrictive spirometric pattern (5•9%). Of the 13 patients with obstructive spirometric pattern, 7 presented a normal FVC (53•9%), and 6 a diminished FVC (46•1%). Regarding the changes post bronchodilator, 6 patients showed significant changes (35•3%), which were all obstructive, and 11 patients had no significant changes (64•7%), being 7 obstructive, 3 normal, and 1 restrictive.
Conclusions: The predominant spirometric pattern of the evaluated patients with CAO-PTB, in the family health center La Florida, Talca, was the obstructive with normal FVC, and no significant changes post bronchodilator were found.
