Summary
Fixing epidural catheters with Tegaderm dressings showed significant migration, even with loops or labels. Current methods are insufficient for a gold standard in epidural catheter fixation.
Area of Science:
- Anesthesiology
- Medical Devices
- Patient Safety
Context:
- Epidural anesthesia effectiveness depends on catheter placement.
- Epidural catheter migration is a known complication.
- Existing fixation methods lack a universally accepted standard.
Purpose:
- To evaluate six fixation methods for epidural catheters using Tegaderm transparent film dressing.
- To compare catheter migration and insertion length changes over two postoperative days.
Summary:
- Six epidural catheter fixation techniques using Tegaderm were tested.
- Methods involved circular loops or straight fixation, with/without record labels.
- Catheter movement was smaller without loops, but significant outward migration occurred in all groups.
Impact:
- Tegaderm fixation alone, with or without modifications, does not establish a gold standard for epidural catheters.
- Further research is needed to develop reliable epidural catheter fixation methods.
