Frequency of obstructive pattern of spirometry in bronchiectasis patients

Methods: this descriptive case series study was conducted in the indoor and outdoor department of pulmonology,lgh,lahore from january 2014 to july 2014. sixty cases of bronchiectasis were included in this study. on the day of the study,spirometry was performed and values of fev1,fvc,fev1/fvc were noted. then these patients were nebulized with 2.5mg salbutamol. after 15 minutes spirometry was performed again and values of the above given parameters were noted. when fev1was less than 80% of predicted and fev1/fvc value was less than 70% the spirometry was considered as obstructive pattern. post bronchodilator improvement in fev1and/or fvc was noted. improvement of 12% in fev1from pre-bronchodilator value was considered as post bronchodilator reversibility.aim: to determine the frequency of obstructive pattern of spirometry in bronchiectasis patients.results: the mean age of the patients was 39.4±14.4 years. there were 34(56.7%) male patients and 26(43.3%) female patients. the mean weight of the patients was 52.1±13.3kg. the mean height of the patients was 156.3±9.5 cm. there were 34(56.7%) patients with obstructive pattern and 26(43.3%) had non obstructive pattern. there were 24(40%) patients who had reversibility and 36(60%) had no reversibility.conclusion: it is concluded that 34(56.7%) patients had obstructive pattern of spirometry and 24(40%) patients had reversibility with short acting beta-2 agonist. © 2014 pakistan journal of medical and health sciences. all rights reserved.
