Abstract
Early and late complications of central venous catheterization were investigated in 488 consecutive catheters, 389 introduced in the subclavian vein by a percutaneous puncture technique, 84 by a cut down technique of the cephalic vein, and 15 by a peel away technique. Care and introduction of the catheters was controlled by the parenteral nutrition team in 239 cases. Immediate and late complications were found using both the puncture and venous cut down techniques, but immediate complications differed in the two groups due to the different methods of insertion. The rate of catheter related sepsis (CRS) did not differ significantly when the group under control of the nutrition team was compared with the group without nutritional control (5.9 vs. 6%). The rate of CRS was 1 CRS/220.7 days of therapy in the puncture group and 1 CRS/342.2 days of therapy in the venous cut down group. Catheter tips and blood were cultured from both CRS and non-CRS patients, and the micro-organisms identified. Catheters were withdrawn, under supervision of the nutrition team, for a number of reasons including death, thrombosis, and technical problems, but suspicion of CRS accounted for a high percentage of withdrawals (18% in the puncture group, 16.6% in the venous cut down group). It is suggested that, when CRS is suspected, removal of the catheter should be delayed until all other possibilities have been investigated.
