Abstract
Recently, the patients with tracheostomy are becoming to increase for prevention of respiratory disorders. It is important problem that tracheostomy is kept in clean condition.
In this study, bacterial contamination of the suction tube and disinfection solutions used for the maintenance of suction tube were examined.
The examined results were as followed.
1. Bacterial contamination of the suction tube increased by prolongation of its using times.
2. The effect of disinfection of the solution were most effective in 0.05% Hibitane, next in 0.02% Hibitane gluconate and most weak in 0.02% Hibitane.
3. Increasing of organisms were restrained by constant changing of the solution in the following time, i.e. every 3 hours in 0.02% Hibitane, every 8 hours in 0.02% Hibitane gluconate and every 12 hours in 0.05% Hibitane.
4. In order to keep of the tube in sterile condition, 0.05% Hibitane might be changed in every 3 hours.
