Abstract

Background: Regular cleaning of the cannula in the trachea is very important for infection prevention. How to wash the tracheal cannula which is good to reduce the possibility of colonies of biofilm-forming bacteria and the growth of bacterial and the pattern of bacterial on the tracheal cannula is still unknown. This study aims to evaluate the efficacy of decontamination of the tracheal cannula using chlorhexidine and NaCl 0.9% in patients using the tracheal cannula to decrease biofilm-forming bacterial colony. Methods: 40 subjects were grouped into 20 subjects in the control group washing the cannula using 0.9% NaCl and the interventional group washing cannula using and with 2.5% chlorhexidine solution and 0.9% NaCl. This study used a parallel randomized controlled trial of 2 groups with a single blinded. Results: 40 subjects studied, 17 subjects (85%) each group produced biofilm-forming bacteria prior to intervention. After intervention in the study group, 15 subjects were biofilm negative and 5 biofilm positive subjects p = 0.001. The most common bacteria found in the control group is Pseudomonas aeruginosa, while in the study group some bacteria such as Acinetobacter sp. and Proteus mirabilis. Amoxicilin-Clavulanate had the highest resistance to biofilm forming bacteria in both groups. Piperacillin, ceftazidime, ciprofloxacin and meropenem have the highest sensitivity to biofilm-forming bacteria. Conclusion: There was a significant decrease in the number of colonies that produced biofilm in the tracheal cannula in the study group compared to the control group in tracheal cannula washing.
