概括
这项研究发现,中央静脉导管 (CVC) 插入部位的导管相关血流感染 (CRBSI) 率相似. 然而,许多CVC被排除在外,可能会对CVC并发症的结果产生偏见.
科学领域:
- 传染性疾病 传染性疾病
- 关键护理医学 关键护理医学
- 医疗设备监控 医疗设备监控
背景情况:
- 中枢静脉导管 (CVC) 在重症监护室 (ICU) 中是必不可少的,但与血液感染有关.
- 插入CVC的位置可能会影响与导管相关的血流感染 (CRBSI) 的风险.
研究的目的:
- 评估中央静脉导管 (CVC) 插入部位与微生物 CVC 并发症发生率之间的关联.
- 为了在全国范围的队列中比较内,大腿骨和下关节内细胞插入部位的CRBSI率.
主要方法:
- 使用了一组全国监测队列 (REA-REZO),其中包括193个ICU.
- 分析了2018年至2022年间55,663个具有尖端培养的CVC的数据.
- 对于内,大腿骨和骨下部位的CRBSI发生率是每1000个CVC天计算的.
主要成果:
- 在三个插入部位中,CRBSI的发病率较低且相似:内 (0.7/1000 CVC天),大腿部 (0.7/1000 CVC天) 和下部 (0.6/1000 CVC天).
- 多变量分析证实,插入部位之间的CRBSI发病率没有显著差异 (p=0.248).
- 引起CRBSI的常见微生物包括凝血酶阴性葡萄球菌,肠杆菌,Candida sp.和金黄色葡萄球菌.
结论:
- 中枢静脉导管插入部位在这个队列中没有显著影响CRBSI的发病率.
- 较低的CRBSI总体发病率表明了有效的感染控制措施.
- 由于许多CVC被排除在外,潜在的选择偏差在解释研究结果时需要谨慎.

Parenteral Nutrition (PN) delivers essential nutrients directly into the bloodstream, bypassing the digestive system. It is commonly used for individuals with severe digestive disorders or conditions that prevent normal nutrient absorption.
PN can be administered through two primary routes:
1. Central Parenteral Nutrition (CPN):
CPN involves delivering a high concentration of nutrients through a large vein. This is typically achieved using a Peripherally Inserted Central Catheter (PICC) or,...

Essential infection prevention measures are based on the knowledge of the infection chain, the modes of transmission in healthcare settings, and the use of the best practices in all healthcare settings. Compulsory public reporting of healthcare-associated infection rates is needed to allow individuals and the community to make informed choices regarding selecting a healthcare facility.
The best practices for preventing healthcare-associated infections include hand hygiene, patient risk...

Healthcare-associated infections (HAIs) occur in a healthcare facility while a person receives care for another ailment. This category also includes work-related infections among healthcare staff.
HAIs significantly increase the cost of health care. Extended stays in healthcare institutions, increased disability, increased costs of medications, including specialized antibiotics, and prolonged recovery times add to the patient's expenses and the healthcare institution and funding bodies.
