Abstract
According to the recommendations by the World Health Organization, the insertion of a peripheral venous catheter (PVC) must be an aseptic procedure while using non-sterile gloves. To overcome this apparent contradiction we have invented and patented (WO/2021/123482) a new device to be used during PVC insertion. The device permits the PVC placement in the vein while avoiding to directly touch the catheter with the fingertips. A total of 16 PVCs were inserted in the veins of a venipuncture anatomic training model while the operator was wearing non-sterile gloves. The gloves had been previously contaminated by embedding the fingertips in an agar plate inoculated with Staphylococcus epidermidis. Following insertion, the PVCs were sterilely removed and deposited on a bacterial culture plate. The tip cultures of PVCs that had been inserted with or without the use of the device were compared. Eight out of eight cultures (100.0%) were positive for S. epidermidis when the PVC had been inserted without using the device, whereas only one out of eight (12.5%) was positive when the device had been used. The single positive tip culture in the latter group corresponded to an insertion in which the operator had inadvertently touched the sterile part of the device while manipulating it. In conclusion, an auxiliary novel device allows the aseptic insertion of PVCs while the operator is wearing non-sterile gloves. Regulatory institutions should consider to recommend the insertion of PVCs by means of devices aimed at avoiding the contamination of the catheter.
