CONTRAST EXTRAVASATION: RISK FACTORS AND GUIDELINES TO PREVENT

RISK FACTORS FOR CONTRAST EXTRAVASATION

1. Thin caliber of i.v cannula

2. Wrist / forearm area

3. History of chemotherapy

4. > 60 yrs age

5. Children

6. Ward lines

7. Difficult i.v cannulation.

    HOW TO REDUCE THE RISK OF CONTRAST EXTRAVASATION

   

1.      Take a new i.v cannula, preferably of 18 gauge.

2.      Saline check for longer duration (upto 40 cc)

3.      Reduce flow rate

4.      To compensate for low flow rate: if the patient is < 70 kg reduce kvp and increase mAs

5.      Reduce PSI in the injector

6.      Inform patient in advance of the risk.

7.      Warming the contrast reduces the viscosity.
