Abstract
Objective To observe the effect of mechanical cleaning and manual cleaning in endotracheal tubes. Methods The contaminated endotracheal tubes from 15 clinical departments in Qingdao Municipal Hospital (East Hospital) from March to November 2015 were selected and divided into 3 groups, using convenient sampling method. Manual cleaning method, manual + ultrasonic cleaning method and mechanical cleaning method with suction head on cleaning frame were used in these 3 groups respectively (group 1, n=713; group 2, n=1 187; group 3, n=1 109) . The cleaning effect of endotracheal tubes in these 3 groups were compared. Results Visual inspection and cleaning test rod inspection method suggest that the rate of return to wash when using mechanical cleaning method with suction head on cleaning frame were 1.80% and 3.84% respectively, which were significantly lower than the other two groups, with statistical differences (χ2=476.49, 40.67; P<0.01) . The rate of qualified drying was 100.00%, higher than the other two groups statistically (χ2=214.38, P<0.01) . Conclusions The mechanical cleaning method with suction head on cleaning frame is an effective cleaning method of endotracheal tubes.
