BACKGROUND. Arterial access site complications remain the most frequent adverse events after percutaneous transluminal procedures. We investigated the safety and efficacy of the pro-coagulant wound dressing Neptune Pad ® compared to conventional manual compression for access site management after peripheral percutaneous interventions.

METHODS. We enrolled 201 consecutive patients and randomly assigned patients for Neptune Pad ® (n=100) vs. conventional manual compression (n=101). Patients were followed clinically until hospital discharge and by duplex ultrasound at 24 hours postprocedure for occurrence of access site complications. Time-to-hemostasis and time-to-ambulation were recorded, patients´ and physicians´ discomfort were measured using a visual analogue scale.

Neptune PAD utilization to accelerate closure of the vascular access site
Device: Neptune P.A.D. (R)
The Neptune Pad ® (Biotronik GmbH & Co. KG, Berlin, Germany) is a soft and hydrophilic wound dressing, which has been developed to accelerate local hemostasis, reduce compression times, enable early ambulation and minimize the risk for bleeding complications. Neptune Pad ® consists of calcium alginate, which is cationically charged and exerts potent procoagulant properties.
Active Comparator: 2
manual compression for closure of the vascular access site
Other: conventional manual compression
The most common technique for puncture site management is manual compression. This technique requires an extended pressure on the puncture site, and after achievement of hemostasis a pressure bandage is applied for several hours at bed rest.


Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion Criteria:
