目的 研究手术期间中心吸引器接口污染对肿瘤细胞种植的影响。方法 对55例恶性肿瘤手术患者所使用的吸引器上接口(即墙壁接口)管腔内外两面以无菌操作方法取样装入试管,另取一棉签同法在下接口(与手术台连接口)管腔内外两面采样,同时送检。经35℃24小时细胞计数。结果 55例恶性肿瘤手术患者所使用的吸引器下接口肿瘤细胞数均>2CUF/cm~2,>60CFU/cm~2者28例,占50.9％(28/55)。结论 本结果提示手术期间中心吸引器接口的污染对肿瘤细胞的种植有明显影响,应对吸引器下接口的清理有充分的认识,以避免因中心吸引器接口污染而导致肿瘤细胞种植的发生。
Objective To study the effect of central aspirator interface contamination on the implantation of tumor cells during surgery. Methods Sampling and loading test tubes on the inside and outside surfaces of the suction device interface (ie, wall interface) of the 55 patients undergoing surgical operation for malignant neoplasms were performed aseptically, and a cotton swab was applied to the lower interface (with the operating table connecting port). Both sides of the cavity are sampled and submitted for inspection. 24-hour cell counting at 35°C. Results The number of tumor cells under the sucker interface used in 55 patients with malignant tumors was >2 CUF/cm~2, and 28 cases were >60 CFU/cm~2, accounting for 50.9% (28/55). Conclusion This result suggests that the contamination of the central aspirator interface during surgery has a significant impact on the cultivation of tumor cells and that there should be sufficient knowledge of the cleanup of the under-the-aspirator interface to avoid the occurrence of tumor cell growth due to contamination of the central aspirator interface.
