概括

在受细菌污染的手术中,手术期间的细胞回收经常导致被回收的血液受到污染. 虽然消毒方法的成功率各不相同,但与手术后感染的直接联系很少,因此需要逐个评估.

科学领域:

麻醉学麻醉学
输血医学输血医学
传染性疾病传染性疾病

背景情况:

术内细胞救援 (ICS) 用于重新注入患者在手术期间丢失的血液.
人们担心,挽回的血液会受到细菌污染,尤其是在细菌污染的手术场所.
在这些环境中,ICS的安全性和有效性需要进行系统的评估.

研究的目的:

系统地审查有关在细菌污染的手术场所内手术时挽救细胞的文献.
检查受污染的血液再注射后的污染水平,除污染策略和临床结果.

主要方法:

根据乔安娜·布里格斯研究所的方法和PRISMA扩展进行了全面的范围审查.
搜索内容包括MEDLINE,Embase,科学网络和Cochrane CENTRAL等.
从39项涉及1654名患者的研究中提取了数据,并进行了描述性合成.

主要成果:

经常报告救援血液的细菌污染,具有可变的阳性培养率.
清除污染的策略,如白细胞枯竭过和抗生素添加剂,显示出不同的有效性.
在15项研究 (1203名患者) 中报告了手术后感染,只有9名患者显示出与重新注射血液有可信的联系.

结论:

挽回血液的细菌污染是常见的,即使在非典型的污染程序中也是如此.
除污染技术的有效性不一致.
由于方法异质性和样本规模小,难以得出关于安全性的最终结论;建议在等待进一步研究之前,逐案使用.

Cleaning, Sterilization, and Disinfection

Cleaning, Sterilization, and Disinfection

Cleaning, disinfection, and sterilization are the methods that help to break the infection chain and prevent disease.
Cleaning
The cleaning process usually involves using water with detergents or enzymatic cleaner and removing foreign material from objects and surfaces, including organic material such as body fluids or inorganic material like soil. Cleaning is performed before high-level disinfection and sterilization because foreign materials on the cover of the devices interfere with process...
