摘　　要： 目的了解医疗机构大瓶装医用超声耦合剂卫生状况。方法 2012年2月—2016年4月,通过现场随机抽样检测方法,对某妇女儿童专科医院使用的大瓶装医用超声耦合剂微生物污染情况进行调查与分析。结果共抽取样本170份,合格25份,合格率为14.71%。来源部门主要为住院病房(58.24%)及手术部门(21.76%);各部门标本合格率比较,差异无统计学意义(P>0.05)。开启前后的耦合剂污染率均达80%以上,差异无统计学意义(P>0.05)。共检出145株病原菌,其中未开启的大瓶装耦合剂中检出18株,已开启的检出127株。开启前后主要污染菌均为洋葱伯克霍尔德菌,分别占83.33%、54.33%,启用后的污染菌还有铜绿假单胞菌及黏质沙雷菌(各占15.75%),复合污染菌中均含黏质沙雷菌。结论大瓶装医用超声耦合剂细菌含量超标严重,生产商应严格质量控制标准,医疗机构在使用中应采取有效清洁消毒措施。 Objective To investigate the hygienic status of large bottles of medical ultrasonic coupling gel in medical institution.Methods From February 2012 to April 2016, microbial contamination of large bottles of medical ultrasonic coupling gel in a women and children＇＇s hospital was investigated and analyzed through on-the-spot random sampling and detection method.Results A total of 170 large bottles of medical ultrasonic coupling gel specimens were collected, 25 specimens were qualified, the qualified rate was 14.71%.Specimens were mainly from inpatient wards（58.24%） and operating departments（21.76%）;there was no statistical difference in the qualified rate of specimens in each department（P〉0.05）.Contamination rates of coupling gel before and after the opening were both〉80%, difference was not significant（P〉0.05）.A total of 145 strains of pathogenic bacteria were isolated, 18 of which were from unopened bottles, and 127 from opened bottles.Burkholderia cepacia was the main strain in both unopened and opened bottles, which accounting for 83.33% and 54.33% respectively,in addition, Pseudomonas aeruginosa and Serratia marcescens were also isolated from opened bottles, both were 15.75%, mixed contamination bacteria all included Serratia marcescens Conclusion The total bacteria counts in medical ultrasonic coupling gel in large bottles exceed the standard seriously, the manufacturer should strictly observe the quality control standards, medical institutions should adopt effective cleaning and disinfection measures.
