MedComp 14F Split Cath Rg Instrucciones De Uso página 6

1. Strict aseptic technique must be used during insertion, maintenance, and
catheter removal procedures. Provide a sterile operative field. The Operating-
Room is the preferred location for catheter placement. Use sterile drapes,
instruments, and accessories. Shave the skin above and below the insertion
site. Perform surgical scrub. Wear gown, cap, gloves, and mask. Have patient
wear mask.
2. The selection of the appropriate catheter length is at the sole discretion of the
physician. To achieve proper tip placement, proper catheter length selection
is important. Routine x-ray should always follow the initial insertion of this
catheter to confirm proper placement prior to use.
3. Administer sufficient local anesthetic to completely anesthetize the insertion
site.
4. Split the arterial and venous lumens by grasping the distal ends and gently
pull apart the lumens to the point printed
"DO NOT SPLIT BEYOND THIS POINT".
Warning: Splitting the lumens beyond this point may result in excess
tunnel bleeding, infection, or damage to the catheter lumens.
5. Attach syringe to tunneling adaptor and prime lumens. Ensure saline exits
both arterial and venous distal tips.
6. Attach temporary lumen clamp between extensions and reference line (dots) as
shown in picture.
7. Remove syringe.
INSERTION:
8. Insert the introducer needle with attached syringe, or into the target vein.
Aspriate to insure proper placement.
9. Remove the syringe, and place thumb over the end of the needle to prevent
blood loss or air embolism. Draw flexible end of guidewire back into advancer
so that only the end of the guidewire is visible. Insert advancer's distal end
into the needle hub. Advance guidewire with forward motion into and past the
needle hub into the target vein.
Caution: The length of the wire inserted is determined by the size of the patient.
Monitor patient for signs of arrhythmia throughout this procedure. The patient
should be placed on a cardiac monitor during this procedure. Cardiac arrhythmias
may result if guidewire is allowed to pass into the right atrium. The guidewire
should be held securely during this procedure.
10. Remove needle, leaving guidewire in the target vein. Enlarge puncture site with
scalpel.
11. Thread dilator(s) over guidewire into the vessel (a slight twisting motion may be
used). Remove dilator(s) when vessel is sufficiently dilated, leaving guidewire in
place.
Caution: Insufficient tissue dilation can cause compression of the catheter lumen
against the guidewire causing difficulty in the insertion and removal of the
guidewire from the catheter. This can lead to bending of the guidewire.
12. Thread Valved Peelable introducer over the proximal end of the guidewire.
Once the Valved Peelable introducer is in target vein, remove the guidewire
leaving the sheath and dilator in position.
Warning: DO NOT bend the sheath/dilator during insertion as bending will cause
the sheath to prematurely tear. Hold sheath/dilator close to the tip (approximately
3cm from tip) when initially inserting through the skin surface. To progress the
sheath/dilator towards the vein, regrasp the sheath/dilator a few centimeters
(approximately 5cm) above the original grasp location and push down on the
sheath/dilator. Repeat procedure until sheath/dilator is fully inserted.
Warning: Never leave sheaths in place as indwelling catheters. Damage to the vein
will occur.
13. Install injection cap over dilator openings to prevent blood loss or air
embolism.
14. Remove dilator and injection cap from sheath.
15. Insert catheter tip into and through the sheath until tip is correctly positioned
in the target vein.
16. Remove the Valved Peelable introducer slowly pulling the sheath out of the
vessel while splitting the sheath by grasping the tabs and pulling them apart.
Warning: Do NOT pull apart the portion of the sheath that remains in the vessel.
To avoid vessel damage, pull back the sheath as far as possible and tear the sheath
only a few centimeters at a time.
Locate lumen in
this area only.
