目的　调查输液反应的原因与医院内感染的关系。方法　细菌检测采用营养琼脂平板接种 ,热原检测采用基质染色法检测微量内毒素。结果　 47例输液反应中有 15例检测有热原或细菌的污染 ,占 3 2 %。结论　输液反应与医院内感染关系非常密切。应加强管理 ,规范医疗行为 ,保证医疗安全 Objective To investigate the relationship between infusion reaction and hospital infection. Methods Bacteria were detected by nutrient agar plating. Pyrogen test was used to detect trace endotoxin by matrix staining. Results In 47 cases of infusion reaction, 15 cases detected pyrogen or bacterial contamination, accounting for 32%. Conclusion The infusion reaction has a close relationship with nosocomial infection. Should strengthen management, standardize medical behavior, ensure medical safety
