This editorial commentary discusses the strategies for prevention of catheter-related bacteremia (CRB) in children on hemodialysis, which is associated with high morbidity and the increase of hospital cost. There is evidence that the use of arteriovenous fistulae in children on hemodialysis is associated with lower infection rates. Therefore, the use of catheters in these patients should be decreased by improving arteriovenous fistulae use rates or by increasing peritoneal dialysis patient recruitment. However, despite the wide adoption of such policies, hemodialysis catheters are still being used in a significant number of cases. For these patients, implementation of effective strategies for preventing contamination of the catheter hub should be a priority. The appropriate recording and evaluation of CRB rates are important for assessing preventive policies. In addition, the successful management of a CRB is essential for preventing recurrence of bacteremia. Recently it was documented in a number of randomized clinical trials that antimicrobial lock solutions were effective for preventing CRB. It is suggested that the use of antimicrobial locks should be considered in children who are at high risk of developing CRB, with caution for their long-term use, because of the possibility of bacterial resistance. Now is the time for action, and all preventive steps should be performed simultaneously to minimize the risk of CRB.
这篇社论评论讨论了预防接受血液透析的儿童发生导管相关菌血症(CRB)的策略,CRB与高发病率及医院成本增加相关。有证据表明,接受血液透析的儿童使用动静脉内瘘与较低的感染率相关。因此,应通过提高动静脉内瘘使用率或增加腹膜透析患者招募来减少这些患者使用导管的情况。然而,尽管广泛采用了此类政策,但仍有大量病例在使用血液透析导管。对于这些患者,实施有效的预防导管接头污染的策略应是首要任务。CRB发生率的适当记录和评估对于评估预防政策很重要。此外,成功管理CRB对于预防菌血症复发至关重要。最近,多项随机临床试验记录表明,抗菌封管液对预防CRB有效。建议对于发生CRB风险高的儿童应考虑使用抗菌封管液,但由于存在细菌耐药的可能性,应谨慎考虑其长期使用。现在是采取行动的时候了,所有预防措施应同时进行,以将CRB风险降至最低。
