Abstract

Background: Insidence of bacterial pneumonia as a nosocomial infection is increasing due to bacteria colonization in the trachea with mechanical ventilator. The risk factors of pneumonia are number of bacteria colonization in upper respiratory tract, especially pathogenous bacteria and patient with age 60 and above. There are some risk factors can increasing VAP incidence, one of them is age. Aim: This study aimed to prove the correlation between age and the number of trachea bacteria in patient with mechanical ventilator. Methods: An observational study with correlation approach between age and the number of trachea bacteria in patient with mechanical ventilator. Data were derived from dr Fitri Hapsari Dewi, Sp.An as resident researcher of ICU patients with mechanical ventilator, total sample of 30 people including criteria. There is two categories of patient’s age. Adolescence from 18 to 59 years old and old age for 60 above. Also derived the number of bacteria before and after oral hygiene. Pearson’s correlation study is used if the data distributed normally. If the data is not distributed normally, Spearman’s correlation study is used. Results: Total number of trachea bacteria is 110,529x106 before oral hygiene and 150,843x106 after oral hygiene. Spearman’s correlation study showed significant correlation between adolescence age and the number of trachea bacteria (p = 0,045). There isn’t significant correlation between elderly age and the number of trachea bacteria (p = 0,570) before oral hygiene. There is significant correlation between the number of trachea bacteria and adolescence group (p = 0,030) after oral hygiene, but there is not significant correlation between the number of trachea bacteria and elderly age group (p = 0,227) after oral hygiene. Conclusions: There is significant correlation between age and number of trachea bacteria in adolescence group used mechanical ventilator, but there isn’t significant correlation in elderly group used mechanical ventilator before and after oral hygiene. Key words: age, the number of trachea bacteria, mechanical ventilator, oral hygiene
