Efficacy of securing cannulae with different taping methods.
This study compared locally available adhesive tapes and dressings in a block randomized, blinded study to determine the force required to dislodge a cannula. In the first stage of the study, various tapes and taping methods were used to secure a cannula to a polyvinylchloride (PVC) pipe. The cannula was attached to a section of a giving set which in turn was attached to a dynamic force transducer. The force required to dislodge the cannula, together with the methods of dislodgement were recorded. In stage two the best taping technique for each type of tape was tested by attaching a cannula to the surface of the forearm of an adult male volunteer. Of the tapes tested we found Leukoplast to be the most effective tape for securing the cannula to the PVC model. On the adult forearm Sleek was as effective as Leukoplast. Orientating the tape parallel to the long axis of the cannula and taping the cannula hub-giving set connection both improved the adherence of the cannula. Under the conditions tested, sterile adhesive dressings and tapes were relatively ineffective in securing the cannulae.
