Venous reactions following insertion of plastic intravenous cannulae were studied in 302 patients. Four types of cannulae of different chemical composition were studied. Venous reactions increased with the duration of infusion and with the addition of irritant drugs to the infusion fluids. The highest incidence of venous reaction occurred with the use of a polyvinyl chloride cannula. There was less reaction associated with the other three cannulae, which were composed of polypropylene, TFE-Teflon, and FEP-Teflon. There was no significant difference between these three cannulae. It is concluded that clinically important differences in complications could not be attributed to the differences in cannula composition.
