一次性医用输注器使用后病原微生物污染的调查研究

Investigation on contamination of pathological microbes after using of disposable transfusion apparatus and syringes

目的:探讨临床使用后的一次性医用输注器具受病原微生物污染情况。方法:通过电脑收费系统,统计2006年5月1日至2007年4月30日广西南溪山医院一次性医用输注器使用的数量和用途,对可疑污染的300付一次性医用输注器具进行普通细菌培养和PCR技术荧光定量检测乙型肝炎、丙型肝炎病毒。结果:使用一次性医用注射器共923676付,其中711216付用于稀释药物,基本无污染,占80.06%;160461付用于肌肉、皮下、皮内注射或造影,为可疑污染,占17.37%;被抗肿瘤药物污染16892付,占1.83%;6801付用于抽取患者血液、其他体液和细胞,被微生物污染,占0.74%。一次性医用输液器198601付,其中对300付感染患者使用后的输注器细菌、病毒检测结果呈阴性。结论:在普通综合性医院用于普通临床输液、注射的一次性医用输注器受病原微生物污染的可能性极小,可作为再生资源。

Objective ： To explore contamination of pathological microbes after using on disposable tranfusion apparatus and syringes. Methods ： By computer charge system in Nanxishan hospital of Guangxi, to analyze the amount of disposable transfusion apparatus and syringes during May, 2006-April, 2007 in Nanxishan hospital. Hepatitis B virus （HBV） and hepatitis C virus （HCV） were tested by flurocencing quality PCR and common culture for general bacteria. Results： A total of 923676 plastic syringes was used; which including that 6801（0. 74%） contained blood and contained other body fluids （urine, gastric secretion, cerebrospinal fluid, wound drainage） and cell during use, 16892（1.83%） contained anticancer drugs and 160461 （17. 37%） were utilized for i. m. , s. c. , or ID injections. 739522（80.06%） were utilized for dilute medicine in i.v. drip. respectively. 198601 of disposable transfusion apparatus was used. 300 pieces of above disposable transfusion apparatus and syringes after used were no contaminated by HBV/HCV and common bacteria. Conclusion： The disposable transfusion apparatus and syringes after using are almost not polluted by pathological microbes in common clinical medical department in general comprehensive hospital, and which might be regenerated.
