Term
What are the 4 main complications associated with infusions?
Definition

1. Infiltration

2. Extravasation

3. Local Infection

4. Venous Spasm

Term
What is infiltration?
Definition
Inadvertent administration of a nonvesicant solution into surrounding tissue.
Term
What are causes of infiltration?
Definition

- Puncture of the distal vein wall during venipuncture.

- Dislodgement of the catheter or needle from the intima of the vein.

- Poorly secured infusion device.

- High delivery rate or pressure from an electronic infusion device.

- Overmanipulation.

Term
What are s/s of an infiltration?
Definition

- Coolness of skin around the site.

- Taut skin.

- Edema at, above or below the insertion site.

- Absence of blood backflow.

Term
How to prevent infiltration?
Definition

- Do not use veins that have had previous punctures or veins that are very fragile due to seeping.

- Turn pts carefully.

- Choose smallest IV catheter.

- Stabilize insertion site.

 

*Check site by gently applying pressure 3 inches above insertion site.  If IV continues to infuse, it's most likely infiltrated. More accurate than checking back flow.

Term
How would you treat an infiltration?
Definition

-  Use warm or cold compresses.

- Elevation of the infiltrated extremity.

- Check infiltration scale. pg 565

Term
What is extravasation?
Definition
The inadvertent administration of a vesicant solution into surrounding tissue.  A vesicant solution is a fluid or medication that causes the formation of blisters, with subsequent sloughing of tissues.
Term
What causes extravasation?
Definition

- Puncture of the distal vein wall during venipuncture.

- Dislodgement of the catheter or needle from the intima of the vein.

- Poorly secured infusion device.

- High delivery rate or pressure from an electronic infusion device.

- Overmanipulation.

 

Term
What are s/s of extravasation?
Definition

- Complaints of pain, tenderness or discomfort.

- Edema at, above or below the insertion site.

- Blanching at the area around the insertion site.

- Change in temperature of the skin at the site.

- Burning at the insertion site or along the venous pathway.

- Feeling of tightness below the site.

Term
How can extravasation be prevented?
Definition

- Knowledge of s/s of extravasation.

- Give continuous vesicant administration into a long-term VAD.

- Assess site for blood flow every hour and assess site for tenderness. 

Term
Treatment for extravasation?
Definition

- Stop IV flow.

- Contact the physician.

- Photograph the area.

- Discontinue catheter.

- May use thermal manipulations, heat/cold depending on solutions.

- Elevate arm slightly, as tolerated.

- Use of antidotes if controversial:

Sodium bicarbonate

Regitine for vasopressors

Term
What is local infection?
Definition
Consists of microbial contamination of the cannula or infusate.
Term
What are causes of local infection?
Definition

- Lack of hand hygiene.

- Inappropriate technique to swab needle-free port before access.

- Catheter left in place more than 72hrs.

- Poor technique.

Term
What are s/s of a local infection?
Definition

- Redness, swelling, induration at the site.

- Temperature changes.

- Possible exudates of purulent material.

- Increased quantity of white blood cells.

- Elevated temperature.

Term
How to prevent local infections?
Definition

- Perform hand hygiene.

- Choose the catheter type, insertion site and technique appropriate for the pt, situation and solution.

- Maintain dressing.

- Maintain aseptic technique during cannula insertion and therapy.

Term
How to treat a local infection?
Definition

- Notify the physician.

- Culture site as ordered.

- Apply a sterile dressing at site.

- Warm moist compresses.

- Antibiotics as ordered.

Term
What is venous spasm?
Definition
A sudden, involuntary contraction of a vein or artery, resulting in temporary cessation of blood flow through a vessel.
Term
What can cause a venous spasm?
Definition

- Administration of cold infusates.

- Mechanical or chemical irritation of the intima of the vein.

Term
What are the s/s of a venous spasm?
Definition

- Sharp pain at the IV site that travels up the arm.

- Slowing of the infusion.

Term
How could you prevent a venous spasm?
Definition

- Dilute the medication additive adequately.

- Keep the IV solution at room temperature.

- Deliver the solution at the prescribed rate.

Term
How can venous spasms be treated?
Definition

- Apply warm compresses to extremity, decrease flow rate until the spasm subsides.

- If the spasm is unrelieved, remove the catheter.
