An additional yield of culture from the removed peritoneal dialysis (PD) catheter in diagnosis of pathogen causing refractory peritonitis was assessed in 118 eligible patients from 7 PD centers. Peritoneal dialysis fluid (PDF) culture identified organisms in 86 (72.9%) patients, while the catheter culture identified organisms in 55 (46.6%) patients. PD catheter culture could additionally identify organisms in 19 patients whose PDF culture were negative, increasing the positive culture rate to 89%, in other word 16.1% reducing the culture-negative rate. PD catheter culture provided additional yield, especially in fungal and enterococcal infections.
在 7 个腹膜透析 (PD) 中心的 118 名合格患者中，评估了从移除的 PD 导管中额外获得的培养物对导致难治性腹膜炎的病原体的诊断价值。腹膜透析液 (PDF) 培养物在 86 名 (72.9%) 患者中鉴定出了病原体，而导管培养物在 55 名 (46.6%) 患者中鉴定出了病原体。PD 导管培养物还可以在 19 名 PDF 培养物阴性的患者中鉴定出病原体，将阳性培养率提高到 89%，换句话说，降低了 16.1%的培养阴性率。PD 导管培养物提供了额外的收益，特别是在真菌感染和肠球菌感染中。
