Midline Catheter Insertion: AST
About Accelerated Seldinger Technique (AST) & Midline Catheter
Accelerated Seldinger technique (AST) is an over the wire catheter insertion technique with several advantages. AST devices combine a needle, guidewire, dilator, and sheath into one unit. This integrated design is simpler than the modified Seldinger technique (MST), it reduces risk of contamination and promotes speed of insertion.
Midline catheters are extended dwelling peripheral IV catheters. Midline catheters are longer than 3 inches, with the catheter tip at the level of or distal to the axilla. It does not require a chest x-ray or catheter tip verification. A midline provides reliable vascular access for patients with difficult intravenous access (DIVA). It is an ideal device for patients requiring 1-4 weeks of IV infusion therapy such as antibiotics, IV hydration, or pain management. Midlines avoid multiple needle sticks to maintain peripheral lines and it reduces thrombosis and central line associated bloodstream infections.
This 8-hour workshop teaches clinicians to use an ultrasound and insert midline catheter with AST technique.
PLEASE NOTE: Attendees require excellent peripheral IV skills, knowledge of vesicant, irritant medications and hypertonic solutions. If needed, please attend the IV refresher and skill enhancement program prior to attending the midline training program.
Who Should Attend this AST Midline Catheter Training Program?
- Registered nurses in acute and alternate care settings with strong established peripheral IV insertion skills
- Radiology technicians, if their scope of practice permits insertion and usage of midline catheters, with strong established peripheral IV insertion skills
- Respiratory technicians, if their scope of practice permits insertion and usage of midline catheters, with strong established peripheral IV insertion skills
