- Abstract
Peripherally inserted central catheters (PICCs) may be used to administer contrast injection during CT (computed tomography) scans to improve diagnostic accuracy. This is usually done with the use of a power injector. Research has shown that misplacement of catheters following contrast injection can occur. The aim of this review was to analyse appropriately positioned pre-scan PICCs that malposition following injection of contrast media during a CT scan, evaluate whether tip location or right or left insertion plays a part in the displacement of PICCs after CT, and to ensure those involved are aware of the risks and the safety checks required following such procedures. A quantitative method was used, gathering information from the team's insertion database to review 2045 records of contrast-injectable PICCs between 1 January 2015 and 30 April 2020. Analysis of the data indicated that 1% of appropriately sited PICCs malposition following contrast CT injection and that the catheter is able to self-correct back to its original position at an average interval of 24-72 hours without any other intervention. Further research is needed to explore other factors that could influence the rate of self-correction and complications of prolonged catheter malposition.
