Surface Landmarks/Positioning
•Positioning
‐ “Frog-leg appearance”: Slight
external rotation at the hip and
flexion at the knee
‐ ABduction of leg with external
rotation at the hip
‐ External rotation at the hip
•Rolled towel under the

Complications
•Complication rates
‐Adults: 0.5-15%, up to 35% for inexperienced
‐Pediatrics: 0.3%-34% (lowest for femoral)
•Risk increases exponentially with increasing
number of attempts
‐Likelihood of failed cannulation correlates with repeated
attempts

Catheter-Associated Bloodstream
Infection (CABSI)
•Most common complication of CVC
•Significant cause of morbidity, mortality and healthcare
costs
•Substantially reduced by using a “bundle” of practices
•Lower risk of infection with subclavian venous access in
adults
•Regardless of site, strict attention insertion technique can
reduce infections

Each subclavian vein is a continuation of the axillary vein and runs from the outer border of the first rib to the border of anterior scalene muscle. From here it joins with the IJ to form the brachiocephalic vein (also known as "innominate vein"). The subclavian vein follows the subclavian artery and is separated from the subclavian artery by the insertion of anterior scalene. Thus, the subclavian vein lies anterior to the anterior scalene while the subclavian artery lies posterior to the anterior scalene (and anterior to the middle scalene). xxx00.#####.ppt 07/16/13 P.

Femoral vein lies in femoral sheath, medial to femoral artery, immediately below inguinal ligament FA is at midpoint btwn ASIS and SP FV formed by joining of deep/superficial veins of the leg, above inguinal ligament becomes external iliac and joins with internal iliac to become common iliac, both common iliacs jon to become IVC xxx00.#####.ppt 07/16/13 P.

In adults, femoral higher risk of infection, thrombosis and art puncture w/o US The more times you attempt, the more likely you are to experience a complication, even if successful However, the more times you do attempt the more likely you are to fail Sig increased risk with 2 needle passes and 3 or more attempts leads to a 6 fold increase in complication risk xxx00.#####.ppt 07/16/13 P.

US vs Landmark: Adult lit. mostly of IJ, limited data for femoral site and in pediatrics, however, some peds studies showed similar results with US used for IJ and suggest benefit for femoral site primarily in reducing complications Operator experience not addressed in many of these studies but two studies suggest the most benefit with inexperienced proceduralists Dynamic vs. static vs landmark PRACTICALLY SPEAKING: detect anatomic variability and avoiding unnecessary complication (i.e. presence of thrombus) xxx00.#####.ppt 07/16/13 P.
