       Pediatrics
Objectives
   •By the end of this workshop, the learner will:
        ‐ Describe the anatomic landmarks used to guide arterial
          catheterization at specified sites of insertion
        ‐ List at least 3 indications and 3 contraindications for arterial
          catheterization

Sites of insertion
   •Radial/Ulnar

   •Axillary

   •Dorsalis pedis

   •Posterior tibial

   •Femoral

Radial
   •Most common site

   •Lies in longitudinal
    groove formed by FCRM
    and distal radius

   •Check for collateral flow

   •Thrombosis is common

Pediatrics               xxx00.#####.ppt 07/10/12 03:53 PM
Axillary
   •Large artery

   •Excellent collateral flow

   •Air/thrombus embolism
    can cause brain/hand
    ischemia

Pediatrics               xxx00.#####.ppt 07/10/12 03:53 PM
Femoral
   •Also large artery

   •May still be palpable
    with marked
    hypotension

   •Lack of collateral flow

   •Air/thrombus embolism
    can cause foot/toe
    ischemia

Pediatrics               xxx00.#####.ppt 07/10/12 03:53 PM
Dorsalis pedis
   •Descends down dorsum
    of foot parallel & lateral
    to EHLT

   •Check for collateral flow
        ‐ Occlude artery

        ‐ Blanch great toe for several
          seconds

        ‐ Release pressure &
          observe for flushing

•Confirm via pressure transduction

   •Tubing used for pressure monitoring should include
    a Luer-lock design

  • #10: Thrombosis and emboli can lead to ischemia and necrosis but is dependent on adequacy of collateral flow Thrombosis longer duration and size of cath relative to arterial lumen diameter leads to greater incidence of thrombosis. Also increased incidence w/repeated punctures and intermittent flushing Emboli More common w/manual intermittent flushing Skin necrosis Prox to radial art insertion site, blood supply to to skin of distal forearm arises directly from branches of rad art. w/o ANY collateral circulation. If cath tip interferes w/these branches then ischemia to skin occurs Prevention: 1) most distal insertion site 2) smallest sized catheter so as to cause the least amt of luminal obstruction 3) prolonged catheterization xxx00.#####.ppt 07/10/12 P.
