目的：确定空气负离子对重症监护室中耐甲氧西林金黄色葡萄球菌 (MRSA) 和不动杆菌定植/感染的影响。设计：在成人普通重症监护室进行的前瞻性单中心交叉研究。患者：201 名在病房停留时间超过 48 小时的患者。干预：设备上安装了六个负离子空气发生器，但在研究的前 5 个月（对照期）未运行。随后设备可运行 5.5 个月。测量和结果：在 10.5 个月内，分别有 30 名和 13 名患者定植/感染 MRSA 和不动杆菌属。与 5 个月的对照期相比，未观察到 MRSA 定植/感染发生变化。不动杆菌病例从 11 例减少到 2 例 (p = 0.007)。结论：电离器可能在预防不动杆菌感染方面发挥作用。
Objective: To determine effect of negative air ions on colonisation/infection with methicillin-resistant Staphylococcus aureus (MRSA) and Acinetobacter species in an intensive care unit. Design: Prospective single-centre cross-over study in an adult general intensive care unit. Patients: 201 patients whose stay on the unit exceeded 48 hour's duration. Intervention:Six negative air ionisers were installed on the unit but not operational for the first 5 months of the study (control period). Devices were then operational for the following 5.5 months. Measurements and results:30 and 13 patients were colonised/infected with MRSA and Acinetobacter spp., respectively, over 10.5 months. No change in MRSA colonisation/infection was observed compared with the 5 month control period. Acinetobacter cases were reduced from 11 to 2 (p = 0.007). Conclusion:Ionisers may have a role in the prevention of Acinetobacter infections.
