Based on the site of entry and the location of the catheter tip, venous access devices (VADs) are categorized as central venous catheters (e.g., centrally inserted central catheters [CICCs] or peripherally inserted central catheters [PICCs]) or peripheral intravenous catheters (e.g., midlines or peripheral intravenous catheters). 1 Critically ill patients in the intensive care unit (ICU) often need venous access. This is done through a non-tunneled central venous catheters (CVC) placed into one of the central veins in the acute setting.
To some degree, these CVCs have a high rate of complications after insertion and while they are in situ. Moreover, they are not intended for usage for an extended time (more than 1-3 weeks). 2
