Abstract

Introduction: Acute exacerbation of COPD (AECOPD) may be triggered by infection with bacteria or viruses or by environmental pollutants; the cause of about one-third of exacerbations cannot be identified. Objective: to determine the most common bacteria in sputum culture of patients with AECOPD hospitalized in Intensive care unit of Clinic for pulmonary disease and TB ”Podhrastovi” in the 2012. Material and methods: This is a retrospective analysis of sputum bacterial cultures of patients with AECOPD treated in the Intensive care unit of Clinic for pulmonary disease and TB ”Podhrastovi” during 2012 .year. Each patient was required to give two sputum for bacterial examination. Each patient was treated with antibiotics prior to admission in Clinic “Podhrastovi”. The results of sputum bacterial culture findings are expressed in absolute number and percentage of examined patients. Results: In 2012, 75 patients with AECOPD were treated in Intensive care unit of Clinic for pulmonary disease and TB”Podhrastovi”. 44 (58.66%) of patients had normal –nonpathogenic – usual bacterial flora isolated in sputum cultures, 31 (41.34%) had a pathogen bacteria in sputum culture as follows: 7 had Streptoccocus pneumoniae, 8 had Klebsiella pneumoniae (2 with Streptococcus pneumoniae, one with Acinetobacter baumani) ,4 Escherichia colli, others are one or two cases with other bacteria. Conclusion: Bacterial airway infections play a great role in many, but not in all, of cases of AECOPD. So there is the need to do a sputum bacterial culture examination in each patient with AECOPD and with appropriate antibiotics to contribute to curing of them.

Key words: AECOPD, bacteria, sputum, bacterial culture.
