Biofilm removal efficacy of vortexing alone was compared with the standard vortexing-sonication procedure. Among 135 removed prostheses, 35 were diagnosed with infection and 100 with aseptic failure. At a cutoff of ≥ 50 CFU/ml, sonication was more sensitive than vortexing (60% versus 40%, P = 0.151), while the specificity was 99% for both methods.
单独涡旋与标准涡旋-超声程序的生物膜去除效果进行了比较。在 135 个取出的假体中,35 个诊断为感染,100 个诊断为无菌性失败。在≥50 CFU/ml 的截止值下,超声处理比涡旋处理更敏感(60%比 40%,P=0.151),而两种方法的特异性均为 99%。
