BACKGROUND: To reduce the risk of accidental needlestick injuries, first active then
passive safety devices were developed on IV catheters. However, whether these
catheters are easy to implement and really protect personnel from accidental
needlestick is untested.
METHODS: In this prospective randomized survey, we compared a passive safety
catheter with an active safety catheter and a nonsafety classic catheter. The main
objective was to evaluate the difficulty of inserting the catheters in terms of the
number of insertion failures, difficulties introducing the catheter and withdrawing
the needle, and the normality of the blood reflux in the delivery system. The second
objective was to determine the degree of exposure to patients’ blood evaluated as
the number of exposures of the staff and blood splashes of the environment, and
the staff’s sense of protection.
RESULTS: Seven hundred fifty-nine assessment cards were collected. The number of
failures for the three catheter groups was similar and not statistically different.
Introduction of the catheter was more difficult with the active safety catheter.
Needle withdrawal was more difficult with the passive safety catheter. The blood
reflux was abnormal more often with the safety catheters. The staff’s exposure was
more frequent with the active safety catheter. The number of blood splashes was
more common with the safety catheters.
CONCLUSIONS: Safety catheters are not superior with regard to failure rate in the
catheter’s placement. Users feel better protected, but find the use of safety catheters
more difficult, and their handling generates more splashing of blood into the
environment. The passive safety catheter is more efficient than the active safety
catheter with regard to ease of introduction of the catheter into the vein and the
staff’s exposure to the patient’s blood.

Accidental needlestick injuries expose health-care
workers to blood-transmitted infectious agents. Expe-
rience shows that even an intense educational policy
with good organization of the care, staffing, and safety
equipment is insufficient to prevent accidental needle-
sticks.

Staff in the anesthesia and emergency depart-
ment reception areas are especially prone to exposure.

To reduce the risk of accidental needlestick with IV
catheters, active safety devices were developed during
the 1990s.

The operator triggers the device using a
specific maneuver. In the 2000s, passive safety devices
have appeared on the market, which do not require
any particular maneuver from the operator because
they are automatically triggered.

These new types of
passive safety IV catheters are placed according to a
technique identical to the classic nonsafety catheters,
but no randomized prospective survey has ever as-
sessed them. The question is whether their insertion is
easy and whether they really protect personnel from
accidental needlestick. The goal of this prospective
randomized survey was to compare a recently mar-
keted passive security catheter (Introcan
®
Safety™) with
an active security catheter (Insyte™ Autoguard™) and a
nonsafety classic catheter (Vialon™). The main objec-
tive of the survey was to evaluate the difficulty of
inserting the catheters. The second objective was to
determine the degree of exposure of personnel to
patients’ blood.
METHODS
After agreement of the local ethics committee, a
randomized prospective survey was conducted in the
operating room and the emergency department over a
5 Mo period to assess 3 peripheral IV 18-gauge diam-
eter catheters. Vialon (BD Medical Systems, Le Pont de
Claix, France) was the nonsafety catheter usually used
in the hospital (18 G, length 30 mm, outer diameter 1.3
mm). Passive safety Introcan Safety catheters (B.Braun
Me ´dical, Boulogne, France) have an insertion identical
