Intravascular cannulas: A survey of patients with intravascular cannulas 

This study set out to determine the most significant variables associated with the use of intravascular (IV) cannulation in the hospital setting. A survey of such cannulas was conducted on patients in the general and paediatric wards of Rotorua Hospital.  It was found that the most significant variables affecting inflammation at the IV site are the combined use of IV medication, and the cannula remaining in situ for more than 48 hours.  On the basis of the results of this research a number of recommendations for practice are made.
