ERCP术后血流感染病原菌分析及护理

目的分析经内镜逆行胰胆管造影（ERCP）术后血流感染的病原菌分布、耐药性情况与护理对策。方法回顾性分析2叭2年1月＆2017年1月667例行ERCP术的患者临床资料，分析ERCP术后发生血流感染的病原菌分布及耐药性情况。结果667例患者ERCP术后发生血流感染共21例，感染率为3．15％；其分离出病原菌27株，其中革兰阴性菌21株，占77．78％，革兰阳性菌6株，占22．22％，复数菌败血症5例18．52％。结论ERCP术后患者血流感染以革兰阴性菌为主，对实施ERcP术后并发血流感染的患者，给予积极有效的治疗同时，加上针对性的护理干预是保证治疗成功、降低并发症的关键。

Objective To analyze the distribution and drug-resistant feature of pathogenic bacteria of postoperative bloodstream infection in patients who underwent endoscopic retrograde cholangiopancreatography （ERCP） and the relative key points of nursing. Methods A total of 667 patients underwent （ ERCP ） between January 2012 and January 2017 in our hospital. Clinical data and pathogen distribution in patients who suffered bloodstream infections after ERCP were analyzed retrospectively. Results Bloodstream infections occurred in 21 patients after ERCP （ total infection rate： 3.15% ） . 27 strains of pathogenic bacteria were isolated, of which 21 （ 77.78% ） were gram negative bacteria and 6 （ 22.22% ） were gram positive bacteria. Conclusion The infections of bloodstream in patients after ERCP are mainly caused by gram negative bacteria. Targeted nursing and aggressive therapies are the key points to treatment success and reduced complications.
