BackgroundCentral venous access is crucial for the provision of adequate parenteral nutrition (PN). The type of central venous access device (CVAD) has evolved over the past 10 years. The most recent trend has been to use peripherally inserted central catheters (PICCs). This development has occurred without controlled clinical trials.MethodsOver a 10-year period, the nutrition support service at a single institution has prospectively collected data on CVADs used for providing PN. The types of CVAD used for providing PN were analyzed, and the major complications associated with CVADs, thrombosis and line sepsis, were compared over three different time periods: 1988-1989; 1992-1993; 1996-1997. In addition, complications associated with PICCs were compared with other CVADs.ResultsThe following were the dominant CVADs over each of the three time periods: 1988-1989: tunneled catheters, 80%; 1992-1993: nontunneled catheters, 46%; and 1996-1997: PICCs, 48%. There was a decreased incidence of sepsis and pneumothorax in 1996-1997 and an increase in severed or leaking catheters and phlebitis. In a comparison of PICC and non-PICC catheters over the past 3 years, there was a trend toward decreasing sepsis with PICC catheters but an increase in malposition, inadvertent removal, and severed or leaking catheters.ConclusionsPICCs have replaced tunneled and nontunneled central catheters as the most commonly used CVAD for providing PN. PICCs do not result in increased line sepsis or thrombosis but have an increased incidence of local complications such as leaking catheters, phlebitis, and malposition.
