INSTRUCTIONS FOR USE
1. If applicable, remove the Luer-lock end cap from each extension.
2. Prepare the catheter for insertion by flushing each of the lumens and clamping or attaching the
injection caps to the appropriate extensions. Leave the distal extension uncapped for wire guide
passage.
3. Introduce thinwall percutaneous entry needle into vessel. Venous blood should be easily aspirated
to confirm position of needle tip within vessel.
4. Slide Safe-T-J wire guide straightener (positioned on distal tip of wire guide) over "J" portion of
®
wire guide. Pass straightened wire guide through needle; advance wire guide 5-10 cm into vessel.
If straight wire is used, always advance soft, flexible end through needle hub and into vessel. If
resistance is encountered during wire guide insertion, do not force wire guide. Withdrawal of wire
guide through needle should be avoided; breakage may result.
5. While maintaining wire guide position, withdraw needle and Safe-T-J wire guide straightener.
6. Enlarge puncture site with number 11 scalpel blade, if required. If dilation is required, dilator can be
advanced over wire guide and removed prior to insertion of central venous catheter.
CAUTION: To avoid vascular injury, do not use excessive force when advancing dilators. Use the
smallest size dilator catheter placement will allow. Wire guide must always lead dilator by several
centimeters. Do not advance dilator more than a few centimeters into the vessel.
7. Measure catheter to be used against patient to determine approximate length of catheter needed
from puncture site to central venous tip position.
NOTE: The Spectrum Glide catheter with EZ-Pass hydrophilic coating may be wetted with sterile
water or saline prior to insertion to activate the coating.
Introduce the central venous catheter over wire guide. While maintaining wire guide position,
advance catheter into vessel with a gentle twisting motion. (Fig. 1)
NOTE: Do not advance catheter tip beyond distal tip of wire guide. Always have wire guide leading
during catheter placement. Verify catheter tip position using radiography or appropriate technology.
In order to guarantee extrapericardial location, the catheter tip should be located above the SVC-RA
junction, within the lower 1/3 of the SVC. Every effort must be made to ascertain proper tip position
in order to prevent erosion or perforation of the central venous system and to ensure proper
delivery of infusates.
