概括
在移除后关闭外部固定针部位可以降低手术部位感染 (SSI) 的风险,而不是保持开放. 这一发现可以改善患者的治疗结果,并在外部固定程序后降低感染率.
科学领域:
- 整形外科手术 整形外科手术
- 传染病控制中的传染病控制
- 生物医学工程 生物医学工程
背景情况:
- 外部固定是一种常见的骨科手术,用于四肢骨折.
- 在移除外部固定物后,针位的护理对于预防手术部位感染 (SSI) 至关重要.
- 在移除外部固定装置后,用于针位管理的现行做法各不相同,需要基于证据的指南.
研究的目的:
- 为了比较外置固定移除后手术部位感染 (SSI) 的发生率.
- 评估主要封闭的针位和由次要意图留开的开放点之间的感染率.
- 在移除外部固定装置后,识别与针位SSI相关的风险因素.
主要方法:
- 这是一项回顾性多中心研究,涉及412名成年患者,他们因四肢骨折而接受外部固定器切除.
- 患者被分为两组:主要封闭的针点和开放的针点,用于二次意图治愈.
- 两个队伍之间的手术部位感染 (SSI) 率进行了比较,随访时间至少为30天.
主要成果:
- 在移除外部固定器后留下开放的针位与SSI的几率显著增加有关 (OR=3.2;p<0.01).
- 骨平原骨折也被确定为针部SSI的独立风险因素 (OR=4.45;p<0.001).
- 与开放组 (19天) 相比,封闭针位组 (11天) 的外部固定器使用时间中位数较短.
结论:
- 移除后外部固定针部位的初级关闭与SSI的风险较低,与二次意图愈合相比.
- 这些发现表明,采用主要关闭针部位可以帮助减少接受外部固定的患者的SSI率.
- 实施基于证据的针位关闭协议可以提高患者的安全性,并减少骨科创伤护理中SSI的发生率.

7.6K
The human skull is composed of several bones that come together to protect the brain and support the structures of the face. The junctions where these bones meet are called sutures.
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...

Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...
