Caution: When using a break-away needle, never
advance the needle or retract the catheter after
inserting it into the needle; the catheter may be severed by this action.
f. With small, gentle nudges, a few millimeters at a
time, advance the catheter through the introducer
to a distance of about 6 to 7 cm into the vein.
g. Once the catheter is successfully advanced to about
6 or 7 cm, withdraw the introducer carefully (an
h. To withdraw the introducer, stabilize the catheter by
applying gentle pressure over the vein proximal to
the introducer, and then remove it carefully from
the insertion site. Break or peel away the introducer
by splitting the wings, and then carefully peel it
i. Continue to advance the catheter into the vein to
the premeasured length, by nudging it farther, a few
millimeters at a time, using the fine forceps.
j. Difficulties in advancing catheter: Gently massage
the vein in the direction of blood flow, proximal to
repositioning the extremity or the head may help.
k. Aspirate to visualize blood return in the catheter,
and flush with 0.5 to 1 mL of heparinized saline to
l. Verify length of catheter inserted and adjust as necessary.
m.Attach sterile extension set as per unit protocol.
n. Apply gentle pressure on insertion site with gauze
Table 32.3 Patient Position and Measurement for PICC Insertion
Site of Insertion Position of Baby Measurement
Antecubital veins Supine, abduct arm 90 degrees from trunk; turn head toward
insertion site to prevent catheter from traveling cephalad
through ipsilateral jugular vein
From planned insertion site, along venous pathway,
to suprasternal notch, to third RICS
Saphenous or popliteal veins Supine for greater saphenous vein, prone for small saphenous or
From planned insertion site, along venous pathway,
Follow approximate venous pathway from planned
insertion site near ear, to jugular vein, right SC
External jugular vein Supine, turn head to side; place roll under neck to cause mild
From planned insertion site, to right SC joint, to
artery between medial side of humeral head and small tuberosity of the humerus
From planned insertion site, to right SC joint, to
PICC, peripherally inserted central catheter; RICS, right intercostal space; SC, sternoclavicular.
