Over a six-year period, 78 chronic peritoneal catheters were implanted in
55 patients; mean age at insertion was 9.6 years (range 0.2 to 19.1 years) and
mean body weight was 28.3 kg (range 4.5 to 63 kg). Singlecuff catheters were
used almost exclusively and were inserted in the midline under general
anesthetic. Complications included leakage (26%) and one-way catheter
obstruction (17%). Exit site and/or tunnel infections developed in 25% and
hernias in 20% of 55 patients. Twenty-six catheters required replacement or
removal. Actuarial catheter survival was 50% at two years. A retrospective
analysis of exit-site infections suggested a significant benefit with
"covered" as opposed to "uncovered" catheters (p <
0.01). Despite difficulties with catheter function only one patient was taken
off CAPD because of a leak into the pleural cavity. Recent experience suggests
that paramedian catheter placement and the use of catheters of an appropriate
length for children will reduce the incidence of leakage and one-way
obstruction.
