Long term central venous access catheters: review of 134 catheters inserted in 100 patients.

Abstract

The first 100 patients at Westmead Centre who received long term central venous access catheters were reviewed. The indication for insertion in 77% of the patients was administration of chemotherapy, 15% had insertion for parenteral nutrition and 8% for blood product administration or anti-microbial therapy. Catheter manipulations were carried out under strict aseptic conditions by a limited group of nursing staff. Of the catheters, 73.1% functioned satisfactorily and were removed electively or were functioning at death or time of review. The main reason for removal was suspected infection, but this was proven in only 4.5% although strongly suspected in another 5.2%. The infection rate was 13 episodes per 13 987 catheter days. The duration of function of catheters was analysed by the life table method, demonstrating a 50% catheter survival rate of 300 days.
