Intravenous infusion bottle plugs as a source of microbial contamination
Abstract:
A technique was described for the artificial contamination of the upper surface of intravenous infusion container plugs with viable micro-organisms. This technique was employed to assess the adequacy of decontamination of two designs of plug by the use of antiseptic swabbing. Results indicated that the MRC plug surface was more difficult to sterilize than that of the Travenol plug. The possibility of contamination of the infusion fluid during insertion of the giving-set needle was examined. Results indicated that there was a risk of contamination through the administration-set port of the MRC plug if swabbing was inadequate.
Insights
This study developed a method to test intravenous infusion plug sterilization. Results showed the MRC plug is harder to sterilize than the Travenol plug, posing a contamination risk if not properly decontaminated.
Area of Science:
- Microbiology
- Infection Control
- Pharmaceutical Technology
Background:
- Intravenous (IV) infusion therapy is crucial but carries infection risks.
- Contamination of IV fluid containers can lead to serious patient infections.
- The design of IV container plugs impacts their susceptibility to microbial contamination and effective decontamination.
Purpose of the Study:
- To develop and describe a technique for artificial microbial contamination of IV infusion container plugs.
- To evaluate the effectiveness of antiseptic swabbing for decontaminating two different plug designs (MRC and Travenol).
- To assess the risk of microbial contamination of the infusion fluid through the administration set port during needle insertion.
Main Methods:
- Artificial contamination of the upper surface of IV infusion container plugs with viable microorganisms.
- Assessment of decontamination efficacy using antiseptic swabbing on two plug designs.
- Examination of potential contamination pathways during administration set needle insertion.
Main Results:
- The MRC plug surface demonstrated greater resistance to sterilization compared to the Travenol plug.
- Inadequate antiseptic swabbing of the MRC plug's administration set port presents a significant risk of infusion fluid contamination.
- The study highlights variations in plug design affecting decontamination effectiveness.
Conclusions:
- The MRC plug design poses a higher risk of microbial contamination during IV fluid administration compared to the Travenol plug.
- Effective and thorough antiseptic swabbing protocols are critical for preventing contamination, especially with the MRC plug.
- Further research into plug design optimization for enhanced microbial resistance is warranted.
