The effectiveness of a Cidex-based decontamination protocol was analyzed for its effectiveness in cleaning various components of a flexible fiberoptic laryngoscope (FFL), including the handle, eyepiece, and detachable light cable. A random microbiological sampling and aerobic bacterial culture analysis of 6 FFL eyepieces, 6 FFL driver handles, and 5 light cables prior to patient use was performed. Of 17 samples collected, 7 (41%) were contaminated with bacterial organisms. Organisms recovered represented both environmental organisms from skin and oral flora origin. This study demonstrates that potential contaminants may be present on FFL eyepieces and light cables, which are commonly overlooked in the cleaning protocols of a standard otolaryngology clinic.
分析了基于 Cidex 的消毒方案在清洁软性纤维喉镜（FFL）的各种部件（包括手柄、目镜和可拆式光电缆）方面的有效性。在患者使用前，对 6 个 FFL 目镜、6 个 FFL 驱动手柄和 5 个光电缆进行了随机微生物采样和需氧细菌培养分析。在收集的 17 个样本中，有 7 个（41%）被细菌污染。回收的生物体既代表了来自皮肤和口腔菌群的环境生物体。这项研究表明，潜在的污染物可能存在于 FFL 目镜和光电缆上，而这些在标准耳鼻喉科诊所的清洁方案中常常被忽视。
