Technologists injecting contrast by hand (syringe and butterfly needle or angiocath
) can easily recognize early signs of extravasation.
He easily identified the needle that injured him as an Angiocath
IV catheter manufactured by Becton-Dickinson Vascular Access, Inc.
Briefly, the needle from an intravenous catheter unit, 24 gauge and 25 mm long (Angiocath
; Becton Dickinson), was roughened along the shaft and then truncated and polished flat, so that it was 3 mm shorter than its 24-gauge, protective catheter.
The Angiocath-N Autoguard and the 22- and 24-gauge Angiocath
Autoguard shielded IV catheters utilize a notched needle technology that allows rapid visualization of blood return and immediate confirmation of placement in the vein.
On the day of the test, each dog was aseptically catheterized using a peripheral intravenous catheter inserted into the cephalic vein (Angiocath
20GA x 1.16in., Becton Dickinson, USA).
An 18 G angiocath
was placed at the vein for propofol infusion, and a 20 G angiocath
was placed in the contralateral radial artery for frequent sampling.
In all patients intravenous line was established with 20 G angiocath
on dorsum of hand with adequate size of vein.
A bolus of gadoteric acid (Dotarem, Guerbet, Aulnay, France) at a concentration of 0.15 mmol per kilogram body weight was injected via a power injector (Spectris; Medrad, Indianola, PA, USA) at a rate of 2.5 mL/s through a 20-gauge antecubital vein intravenous catheter (Angiocath
; Infusion Therapy Systems, Sandy, UT, USA).
