术后患者一次性引流管(袋)细菌污染的研究

本文介绍了101例术后患者对151根一次性引流管(袋)引流物细菌污染程度。按常规细菌分离鉴定方法,发现污染率最高的细菌是金葡菌、肠球菌,检出率均为20％;大肠杆菌16％;克雷伯氏菌和真菌均为12％,占总检出率80％。其次是绿脓杆菌、醋酸钙不动杆菌、黄杆菌、阴沟肠杆菌和表皮葡萄球菌,检出率均为4％,占总检出率的20％。而这些细菌又为医院感染的重要条件致病菌。对一次性引流管(袋)24～48小时使用进行了探讨。

A Research on the Bacterial Infection of postoperative Patients with Single-use Drainage Tube(Bag)

The degree of drain's bacterial infection was de- termined in 101 post-operative patients with 151 sin- gle-use drainage pipes(bags). By using routine method of isolation and identification, among the 80% of total positive rate, Staphylococci aureus and Group D-Enterococci both had the highest rate with 20% contamination, E. coli 16%, Krebsiella and Fungus both were 12%. The rest twenty percent was Pseudomonas aeruginosa, Acinetobacter calcoacetius, Flavobacterium, Enterobacter cloacae and Staphylococci epidermidis, each was 4%. All these bacteria are important (opportunistic) pathogens of nosocomial infections. Twenty-four hours' use of sin- gle-use drainage tube(bag) was also discussed in the paper.
