概括
下肢骨折内部固定后软组织片覆盖的延迟增加了感染风险. 建议在内固定后72小时内覆盖伤口,以减轻感染.
科学领域:
- 整形外科的整形外科手术.
- 创伤外科手术是什么
- 伤口愈合 伤口愈合
背景情况:
- 较短的延迟软组织覆盖下肢开口骨折的较短延迟与减少的感染率相关.
- 整形整形团队需要了解安全的片延迟时间后内部固定 (IF),而不仅仅是后呈现,由于并发的关键损伤.
- 这项研究调查了基于24小时内,24-72小时内和IF后72小时内覆盖延迟的感染率.
研究的目的:
- 确定严重下肢骨折的患者内部固定后片覆盖的最佳时间.
- 在复杂的骨折病例中,确定在盖覆盖后感染的预测因素.
- 评估覆盖延迟和随后的感染率之间的关系.
主要方法:
- 对274名在1级创伤中心 (2011-2021) 治疗的Gustilo III下肢骨折的成年患者进行了回顾性队列研究.
- 患者在内部固定后接受了盖覆盖.
- 多变量逻辑回归分析了感染预测因素,包括人口统计,片类型,固定方法,抗生素和相对于呈现和固定的覆盖时间.
主要成果:
- 在274名患者中,76名 (27.7%) 患有感染.
- 从固定到覆盖的平均时间为非感染患者的84.9小时,感染患者的106.6小时 (p=0.074).
- 护覆盖延迟 <24小时,24-72小时和>72小时的感染率分别为23.2%,25.0%和31.5% (p=0.40). 从固定到盖覆盖的时间是感染的唯一显著预测因素 (p=0.04).
结论:
- 内部固定和盖覆盖之间的时间间隔是术后伤口感染的重要预测因素.
- 虽然72小时以上延迟的感染率在这个队列中没有达到统计学意义,但更大的研究可能会证实这一趋势.
- 软组织覆盖最好在内固定后72小时内进行,以最大限度地降低下肢开口骨折的感染风险.

Fractures: Bone Repair
2.8K
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...

Flail Chest-II
136
Managing flail chest, a condition characterized by a segment of the chest wall moving independently from the rest of the thoracic cage, requires a comprehensive approach. It includes a thorough assessment of the patient's condition, a diagnostic evaluation to determine the extent of the injury, and the implementation of appropriate medical interventions tailored to the individual's needs.
