Complications of central venous access devices in children with and without cancer

Objective: Complications of indwelling central venous access devices (CVAD) were assessed in 63 children with cancer and 35 without cancer. Methodology: Central venous access devices placed surgically in 1991 were reviewed for complications. Results: In cancer patients, the median CVAD duration was 211 days (range 9-924), compared to 37 days (range 3-339) in the non-cancer patients. Although significantly more CVAD, 41 of 72 (57%), were infected in the cancer patients compared to 14 of 40 (35%) CVAD in the non-cancer patients (OR=2.46, 95% CI 1.03-5.93), the rate of line infection in cancer patients was lower: 2.8 per 1000 catheter days compared with 7.6 per 1000 in non-cancer patients (P=0.0014). Infection was significantly more common in intensive chemotherapy cancer patients (P=0.0002). Conclusions: Treating infected CVAD with antibiotics or hydrochloric acid (HCl), clearing occluded lines with streptokinase/HCl and repairing fractured lines, when successful, resulted in a considerable gain in the number of days of use for the CVAD.
