OBJECTIVE
The authors had for aim to study reservoirs and transmission of Pseudomonas aeruginosa in an intensive care unit.
DESIGN
A 6-month prospective descriptive study was made on water samples, samples from hands of health care workers, and clinical samples. P. aeruginosa strains were compared by pulsed-field gel electrophoresis.
RESULTS
Among the 211 patients hospitalized during the study, 14 (6.6%) were infected by P. aeruginosa. Out of 494 water samples, 80 were contaminated by P. aeruginosa. The regularly disinfected water taps were more rarely contaminated than the others (P<10(-5)). Out of 140 hand samples, one showed contamination from an infected patient.
CONCLUSIONS
aeruginosa cross transmission was observed during this study. We should follow strict hygienic precautions such as wearing gloves and performing thorough alcoholic rub disinfection. Water taps are often contaminated and require regular disinfection.
目的
作者旨在研究重症监护病房中铜绿假单胞菌的储存库及传播情况。
设计
对水样、医护人员手部样本及临床样本进行了为期6个月的前瞻性描述性研究。通过脉冲场凝胶电泳对铜绿假单胞菌菌株进行比较。
结果
在研究期间住院的211例患者中，14例（6.6%）感染了铜绿假单胞菌。在494份水样中，80份被铜绿假单胞菌污染。定期消毒的水龙头污染比其他水龙头少见（P<10⁻⁵）。在140份手部样本中，1份显示来自感染患者的污染。
结论
在本研究中观察到了铜绿假单胞菌的交叉传播。我们应遵循严格的卫生预防措施，如戴手套和进行彻底的酒精擦手消毒。水龙头经常被污染，需要定期消毒。
