目的探讨内镜中心发生医院感染的危险因素及对应措施。方法回顾性分析行内镜诊疗的560例患者临床资料,对医院感染的各项危险因素进行统计分析。结果医院感染在年龄是否>65岁、是否有2种以上并发症、有无皮肤或黏膜糜烂、是否使用免疫抑制剂、使用广谱抗生素时间是否≥20d及住院时间是否>40d等方面差异有统计学意义(P<0.05);560例中并发感染107例(19.1%),以呼吸系统和泌尿系统感染为主,其中≥2个部位感染10例,因感染死亡24例(4.3%);细菌培养检测出86株病原菌,以幽门螺旋杆菌最多,肺炎克雷伯杆菌其次,其中合并2种病原菌感染5例,3种病原菌感染3例,4种以上病原菌感染2例;行胃镜检查感染率明显高于其他内镜检查(P<0.05)。结论医院感染的危险因素有年龄偏高、存在多种并发症、有皮肤黏膜糜烂、长期应用广谱抗生素或免疫抑制剂、住院时间长,并与病原菌及内镜类型有关。
Objective To investigate the risk factors and corresponding measures of nosocomial infection in endoscopic center. Methods The clinical data of 560 patients undergoing endoscopic diagnosis and treatment were analyzed retrospectively. All the risk factors of nosocomial infection were analyzed statistically. Results hospital infection in the age of> 65 years old, whether there are more than 2 complications, with or without skin erosion, immunosuppressive agents, the use of broad-spectrum antibiotics for ≥ 20d and hospital stay> 40d and other differences were statistically (P0.05) .Of the 560 cases, 107 cases (19.1%) were complicated with infection, mainly respiratory system and urinary system infection. Among them, 10 cases were infected at 2 sites and 24 cases were infected by infection (4.3%). Bacteria 86 pathogenic bacteria were detected and detected, among which Helicobacter pylori was the most, Klebsiella pneumoniae was secondly, 5 were combined with 2 pathogens, 3 were infected by 3 pathogens and 2 were infected by 4 or more pathogens. The infection rate by gastroscopy was obvious Higher than other endoscopy (P <0.05). Conclusion The risk factors of nosocomial infection are high age, multiple complications, skin mucosal erosion, long-term use of broad-spectrum antibiotics or immunosuppressive agents, long hospital stay, and pathogenic bacteria and endoscopic types.
