Insights
Prespiking intravenous (IV) fluid bags within 4 hours poses no infection risk. This study found no bacterial growth in IV bags prepared in perioperative settings, ensuring patient safety.
Area of Science:
- Medical Microbiology
- Perioperative Care
- Infection Control
Background:
- Increasing operative cases necessitate efficiency and patient safety improvements.
- The safety of prespiking intravenous (IV) fluid bags requires investigation regarding infection risk.
- No prior studies assessed infection risk related to the duration of IV bag spiking.
Purpose of the Study:
- To determine if spiking intravenous fluid bags within 4 hours increases infection risk.
- To evaluate the safety of prespiking IV bags in a perioperative environment.
Main Methods:
- Five IV administration sets were spiked weekly for 5 weeks in perioperative areas.
- Samples were collected from spiked IV sets and inoculated into growth media.
- Microbial growth was assessed to identify positive samples.
Main Results:
- A total of 125 samples (250 specimens) were collected over 5 weeks.
- No bacterial growth was detected in any of the collected specimens.
- The 95% confidence interval for contamination was estimated between 0% and 6.3%.
Conclusions:
- Prespiking normal saline IV bags within 4 hours is safe in perioperative settings.
- No increased risk of infection was identified for prespiked IV bags.
- This practice can be implemented to improve efficiency without compromising patient safety.
Background:
As the number of operative cases increases, there is a greater emphasis on reducing inefficiency while maintaining patient safety. Recently, the issue of prespiking intravenous (IV) bags was raised. No study has assessed whether the risk of infection is related to the length of time a sterile (IV) fluid bag has been spiked. After completion of a pilot study revealed no microbial growth within 24 hours of an IV spike, a larger formal study was undertaken to determine whether there was an increased infection risk within 4 hours of spiking an intravenous fluid bag.
Methods:
Five IV administration sets were spiked and hung in busy perioperative areas once a week for a 5-week period. Five samples were drawn from each IV set. Approximately 10 mL was collected per sample. All samples were inoculated in 2 separate growth media. If any growth was noted, the sample was marked as positive.
Results:
A total of 125 samples were collected over a period of 5 weeks, yielding 250 specimens. No samples were excluded from the study. No growth was identified in any of the specimens. The 95% confidence interval was estimated to be 0, 0.063.
Discussion:
There was no bacterial growth in prespiked normal saline IV bags in a perioperative environment. Thus, prespiking of normal saline IV bags in advance should pose no risk of infection to a patient if prepared within 4 hours.
