This prospective randomized controlled study with 975 nontunneled central venous catheters (CVCs) showed that the semiquantitative roll-plate culture technique (SQC) was as accurate as the sonication method for diagnosis of catheter-related infections. Sonication is difficult to standardize, whereas SQC is simpler, faster, and as reliable as the sonication method for culturing CVCs.
本项前瞻性随机对照研究纳入了 975 例非隧道式中心静脉导管(CVC),结果表明,半定量滚板培养技术(SQC)与超声法诊断导管相关性感染的准确性相当。超声法操作较难标准化,而 SQC 则更简单、快速,且与超声法培养 CVC 一样可靠。
