Special Instructions for Guidewires
Note: This information applies only to the use of guidewires
in the Seldinger technique of catheter placement in the
vasculature.
Note: This procedure should be performed only after a
thorough review of technical references, which emphasize
precautions, contraindications, and risks in much greater
detail.
This spring guidewire was designed for single patient –
one time use only.
It is recommended that guidewires be discarded after one
use. No cleaning agents or techniques will completely
remove residual material from the guidewire after use.
INSPECTION
Guidewires should be routinely inspected prior to use and
discarded should any deformities be present in the guidewire.
Guidewire placement should be routinely monitored by x-ray
or fluoroscopic procedure.
CAUTIONS
Because of the delicate and fragile nature of guidewires,
extra care in handling must be taken. Avoid bending or
kinking.
During storage or procedures avoid coiling guidewires in less
than 8-inch diameters as smaller diameters place unnecessary
stress on the guidewires. The provided dispenser is the best
means of storage and handling of the guidewire.
Should resistance occur during insertion, DO NOT advance
guidewire.
Avoid withdrawing guidewire through metal needles;
guidewires may shear or PTFE coating may scrape off
against the needle bevel.
Movable core of guidewire should not be advanced while
guidewire is in patient as this could cause damage to the
guidewire and possible injury to the vessel.
Sufficient guidewire length must remain exposed to maintain
firm grip on guidewires at all times.
PTFE coated guidewires must never be subject to ultra-sonic
cleaning or irradiation sterilization.
TECHNIQUE
1. PUNCTURE VESSEL
Needle Cannula in Vessel
2.
Pass the guidewire through the needle and advance
5-10cm of the guidewire into the punctured vessel. It
may be necessary to manipulate the guidewire in order
to successfully advance it. Usually a gentle, rotating
motion is sufficient to traverse an obstruction. Avoid
rough or overly vigorous manipulation of the guidewire
to prevent damage to the guidewire or the vessel.
If “J” wire is used, prepare “J” guidewire by sliding the
plastic insertion sleeve over “J” tip to straighten it.
Insert the “J” guidewire into the needle hub and gently
advance it.
