Abstract: A transparent, self-adhesive film dressing with a special aerating fenestra, is provided for efficiently securing an percutaneous catheter to the skin of the patient, for continual and complete visual inspection of the insertion penetration site and catheter, without encouraging growth of bacteria. The film is configured with an open aperture located directly over and surrounding the insertion penetration site, to provide continual aeration and allow the incision site to remain uncovered and accessible to ambient air, and thus remaining dry, preventing accumulation and maintenance of a warm moist environment, discouraging growth of bacteria, and decreasing relative risk of penetration site infection. The surrounding film is transparent for visual inspection, and is adhesive and large enough to serve as an efficient anchor to prevent accidental dislodgement of the catheter, but is no longer an infection hazard.
