Abstract
To define the risks associated with central venous catheterization for total parenteral nutrition (TPN) 3291 patient days of this therapy, delivered by an established nutrition support team, were evaluated. One hundred and seventy-five catheters placed in 104 patients were reviewed over an 18 month period. Positive cultures were reported on 11 cannulae for a 6.4% incidence of colonization; five catheters (2.8%) were considered septic. Pleural or mediastinal complications of subclavian or internal jugular venipuncture occurred in eight patients (4.8%). Misdirection of the catheter tip occurred in 11.5% of insertions. Five patients (4.8%) had clinically apparent thrombosis in the superior vena cava, innominate and/or subclavian veins during hospitalization; four others had evidence of thrombosis at autopsy examination, giving an incidence of 8.7% in the entire series. No death directly resulted from the use of this therapy. Compliance with a rigid protocol by an experienced team can allow safe and effective use of central venous catheters and parenteral nutrition therapy.
