A comparative study of intravenous cannulae--'Venflon' with valved sideport and 'Intraflux' with membranous sideport.
The rate of contamination of the inner surface of 'Venflon' type cannulae with valved injection sideports was compared with that of 'Intraflux' type cannulae with membranous injection sideports. Of 46 'Venflon' cannulae and 34 'Intraflux' cannulae, 17.4 per cent and 20.6 per cent, respectively, were contaminated and no correlation of contamination of lumen was found with frequency of use of the sideports in the different cannulae, or with duration of use of the cannulae.
