Bacteria spectrum and prognosis of exit-site infection in peritoneal dialysis patients / 中华肾脏病杂志

ABSTRACT

Objective To investigate the bacteria spectrum and prognosis of exit-site infection in peritoneal dialysis patients. Methods Perfect exit, equivocal exit, exit-site infection (ESI) and tunnel infection (TI) were classified. Incidence of ESI, bacteria spectrum, treatment effect and prognosis were statistic. Results Sixty-nine patients' exits were examined monthly, twenty-one episodes of ESI were occurred during eighteen months. Main pathogens of exit-site infection were staphylococcus aureus (47. 6% ) and pseudomonas aeruginosa(28. 6% ) . Seventeen episodes of ESI were cured. Four episodes of ESI accompanied with tunnel infections. TI rate diagnosed by clinical observation and ultrasound was 0. 012/patient-year and 0. 036/patient-year respectively. Conclusions The outcome of catheters is associated with the regiment of bacteria. Tunnel infection often occurs in whom with a long time exit-site infection. Ultrasound examination can clarify the diagnosis simply and quickly.
