In Study, Peripheral IV Catheter Shows Promise in Intravenous Therapy

In Study, Peripheral IV Catheter Shows Promise in Intravenous Therapy

Background and Significance: Many hospitalized patients require an intravenous (IV) catheter to maintain vascular ac-­ cess or for administration of fluids and medications. The best approach to attaining peripheral intravenous (PIV) access for long term therapy is unknown, particularly in patients with a history of difficult IV placement.

Purpose: To measure clinical outcomes using a Modified Seldinger Technique (MST) with ultrasound (US) guidance to achieve and maintain PIV for long term IV therapy.

Methods: Subjects were patients with a history of difficult peripheral intravenous catheter placement and need for IV therapy longer than 72 hours. Modified Seldinger Technique was used with US guidance to place all PIVs in the deep veins of the upper extremities.

Results: A convenience sample of 157 subjects was enrolled in the study. Mean dwell time for catheter duration was seven days. First attempt placement success was 95%, 88.5% of patients had completion of IV therapy, and a low overall com-­ plication rate (9.57/1000 catheter days).

Conclusion: Using MST for access for long term PIV therapy was associated with low complications and effective in our study population. Using MST requires specialized knowledge and skills, including the use of US and specialized insertion techniques. In patients who require extended PIV therapy with a history of difficult IV placement, this type of insertion technique may have benefit.

Accelerated Seldinger Technique*:

Accelerated Seldinger Technique (AST)

Passive Needlestick safety

Designed to reduce risk of bleeding, air embolism, contamination, guidewire embolism, loss of cannulation

“Fast-flash” for earlier detection of vessel entry

Extended Dwell Catheter:

Highest completion of therapy, lowest complicationof any VAD*

Certified for up to 300psi (5cc/sec) power injections

Up to 29 days allowable dwell time (per FDA clearance)

Blood drawable

An extended dwell peripheral IV catheter (80mm long), the 300 psi (5cc/sec) POWERWAND with built-in StatLock® compatibility establishes a new standard for power-injectable vascular access. Inserted using The WAND’s Accelerated Seldinger Technique (AST), the POWERWAND offers a faster, safer and simpler approach to peripheral intravenous catheterization.

Researchers said the FDA-cleared POWERWAND was successfully placed on first

attempt 95% of the time, in a challenging population of patients with a history of difficult IV

access. There was also a highly favorable rate of IV therapy completion — 88.5% of cases.
