Infections of Port Access Catheters in Children

 The most important complication of port access catheters (PAC) compared to peripheral lines is a higher incidence of infections.

 This study investigated the frequency of catheter infection and related factors in Dr. Sheikh Children Hospital (SCH).

 This is a retrospective descriptive study at Sheikh children’s hospital, Mashhad, Iran. The data of children with an operation for PAC surgery were gathered from hospital files and completed by calling the parents. The definition of PAC infection was based on clinical signs of catheter infection and any positive blood culture (peripheral or catheter sample) or the resolution of signs of infection after the extraction of the catheter in the absence of positive blood cultures.

 During six years, 70 children received PAC, all of whom (except five) were followed by telephone calls. Forty percent of them were younger than two years, and 71.4% had malignant disease. Catheter infection occurred in 16 (22.8%) cases. Signs of catheter infection were fever and cellulitis over the port in nine (56%) cases (pocket infection), chills and fever during catheter usage (without port infection) in six (37.5%) cases, and persistent fever in one patient (6.2%). Blood culture was positive in 75% (12 cases) of catheter infections, and the responsible organisms were Gram-negative bacilli (five cases), Coagulase-negative staphylococci (three cases), Candida (three cases), and group B streptococci (GBS). The success rate for “medical therapy per se” was 68% in catheter infections. The catheter was removed in 22 (31.4%) patients, which was due to infection in half of them. The mean time to removal was 15.3 months.

 The incidence of catheter infection, especially pocket infection, is high in this population, which necessities revision in all procedures of catheter implantation and care.
