Direct susceptibility testing was performed on 110 specimens of wound exudates. Growth was inadequate in 76 of these specimens. Of the remaining 34 specimens, only 5 produced results corresponding to those obtained by testing individual bacterial isolates by the Kirby-Bauer technique. This study confirms that direct susceptibility testing of wound exudates may provide misleading and clinically unreliable information on more than 95% of specimens.
对110份伤口渗出液标本进行了直接药敏试验。其中76份标本生长情况不佳。在其余34份标本中,只有5份的结果与通过Kirby-Bauer技术对单个细菌分离株进行检测所获得的结果一致。本研究证实,对伤口渗出液进行直接药敏试验可能会为超过95%的标本提供误导性且临床不可靠的信息。
