    2.what are symptoms
    3.how to tx
    • 1. fluid/drugs leak into surrounding tissue
    • 2.pain, delayed absorp of drug and tissue damage
    • 3. remove IV, apply pressure to stop bleeding & disperse solution??
    • May infiltratie several mL of 1% procaine (vasodilates and relieves pain)
  7. How to prevent Intra-arterial puncture?
    • 1. palpate (pulse = artery)
