Effectiveness of the transparent sterile dressing vs standard to fix the peripheral venous catheter (PVC), on the incidence of phlebitis. A randomized controlled trial.
Introduction: The type of dressing could contribute to the incidence of phlebitis, infiltration and accidental removals but the results of the studies are contrasting and samples are limited.
Aim: To compare the effectiveness of a transparent polyurethane sterile dressing on the rate of phlebitis associated to peripheral venous catheter (PVC) vs a non sterile sticking plaster in use in current practice (standard dressing).
Design: Randomized controlled trial. Participants. 1061 PVCs (703 patients, adults and children) at a research orthopedic hospital in the north of Italy; 540 PVCs allocated to receive the sterile and 521 the standard dressing.
Results: 96 PVCs were excluded for phlebitis, 48 (9.6%) in the sterile and 48 (10.1%) in the standard dressing group, RR 0.96 (95%CI 0.697 - 1.335). Accidental removal of the PVCs was more frequent with the sterile dressing (9.6% vs 6.3%) but the number of catheters removed without complications was larger in the standard dressing group (48.9% vs 54.9% P=0.0503). Eighty-five PVCs were replaced for detachment of the dressing (50, 9.2% sterile and 35, 6.7% standard dressing). The cheapest transparent sterile dressing costs 32 cents while the standard 9 cents.
Conclusions: A sticking non sterile plasters is not influential on the rate of phlebitis and ensures an good fix of the PVC compared the transparent sterile dressing to of polyurethane film.
