Abstract:
In this study, we investigated four clinical cases of microbial contamination of in-use intravenous infusion fluid, detected by measuring "Adenosine triphosphate (ATP) + adenosine monophosphate (AMP)" ("ATP+AMP") levels. High "ATP+AMP" values correlate with microbial contamination, and by utilizing these values as indicator for microbial contamination possibility, we were able to rapidly detect the contamination and recommend replacement of catheters and administration sets. In three out of four cases, changing the infusion fluid led to improvement in the condition of the patients. "ATP+AMP" levels can be used to confirm microbial contamination of in-use intravenous infusion fluids, as it is fast (several minites) and convenient to measure them.
Insights
Rapidly detect microbial contamination in IV fluids using Adenosine triphosphate (ATP) + adenosine monophosphate (AMP) levels. This method quickly identifies contaminated fluids, enabling timely intervention and improving patient outcomes.
Area of Science:
- Clinical Microbiology
- Biochemistry
- Infection Control
Background:
- Intravenous (IV) infusion fluids are susceptible to microbial contamination.
- Current detection methods can be time-consuming, delaying necessary interventions.
- Early detection of contamination is crucial for patient safety and effective treatment.
Purpose of the Study:
- To evaluate the utility of Adenosine triphosphate (ATP) + adenosine monophosphate (AMP) ("ATP+AMP") levels for detecting microbial contamination in in-use IV infusion fluids.
- To assess the correlation between "ATP+AMP" levels and the presence of microbial contamination.
- To determine the clinical impact of using "ATP+AMP" measurements for guiding interventions.
Main Methods:
- Measurement of "ATP+AMP" levels in four clinical cases of suspected IV fluid contamination.
- Correlation analysis between "ATP+AMP" values and microbial contamination.
- Clinical observation of patient outcomes following interventions based on "ATP+AMP" results.
Main Results:
- Elevated "ATP+AMP" levels were observed in cases of microbial contamination.
- High "ATP+AMP" values served as reliable indicators for contamination possibility.
- In three of four cases, replacing contaminated infusion fluid led to patient improvement.
Conclusions:
- "ATP+AMP" levels provide a rapid and convenient method for confirming microbial contamination in in-use IV infusion fluids.
- This assay can be a valuable tool for infection control and improving patient care in clinical settings.
- Prompt detection and intervention based on "ATP+AMP" measurements can positively impact patient recovery.
