Abstract
Total parenteral nutrition lines are commonly tunneled subcutaneously to decrease rates of sepsis. The history of line tunneling is discussed briefly, noting that to date a surgical approach, a detachable hub catheter or more recently a tunneling rod and 'peel away' introducer have been necessary for this form of central venous access. These systems have problems associated with cost, catheter type and insertion technique.
