“When planning parenteral nutrition (PN), the proper choice, insertion, and nursing of the venous access are of paramount importance. In hospitalized patients, PN can be delivered through short-term, non- tunneled central venous catheters, through peripherally inserted central catheters (PICC), or – for limited period of time and with limitation in the osmolarity and composition of the solution – through peripheral venous access devices (short cannulas and midline catheters). Home PN usually requires PICCs or – if planned for an extended or unlimited time – long-term venous access devices (tunneled catheters and totally implantable ports).” (Pittiruti et al 2009).
