“…Sideports consisting of latex or similar membranes have been proposed as an alternative to the valved system. However, Jakobsen and Grabe (1983) have demonstrated that the use of these membranous sideports does not reduce the rate of contamination in comparison to the valved system. Furthermore, with the emergence of blood-borne diseases such as hepatitis B and AIDS, the need to use needles to give fluids via the membrane sideports, close to a venepuncture site which may be contaminated with blood products, is not ideal.…”
