Problem Venipuncture Sites Flashcards
Problem Venipuncture Sites
- Burns, scars, or tattoos
- Damaged Veins
- Edema
- Hematoma
- Mastectomy (surgical breast removal)
- Obesity
Burns, scars, or tattoos
● Healed burn sites & areas with extensive scarring
○ may have impaired circulation
● Newly burned areas:
○ painful; susceptible to infection
● Tattooed areas
○ impaired circulation,
○ more susceptible to infection
○ contain dyes that can interfere with testing
- Damaged Veins
● hard and cord-like; occluded or obstructed
● sclerosed (hardened)
● thrombosed (clotted)
● Scarring caused by numerous venipunctures
● Choose another site if possible
● draw below (distal to) damaged veins
- Edema
● may yield inaccurate test results
(contamination with tissue fluid )
● veins are harder to locate
● tissue is often fragile and easily injured by
tourniquet and antiseptic application
● healing may be prolonged
- Hematoma
● Swelling or mass of blood that can be caused by blood
leaking from a blood vessel during or following
venipuncture
hard and cord-like; occluded or obstructed
Damaged Veins
- Mastectomy (surgical breast removal)
● Lymph node removal causes lymphostasis (obstruction
or stoppage of normal lymph flow)
● susceptible to swelling and infection
● Applying a tourniquet to the arm can cause injury
● lymphostasis can change blood composition in that arm
- Obesity
● Veins may be deep and difficult to find
● Proper tourniquet selection and application
● median cubital vein
● cephalic vein
● To locate the cephalic vein, rotate the
patient’s arm so that the hand is prone
