概括
手术头盔系统 (SHS) 可能会增加关节塑性手术中的污染风险. 密封手套连衣接口 (GGI) 和每小时更换手套对于降低周围假肢关节感染 (PJI) 风险至关重要.
科学领域:
- 整形外科手术 整形外科手术
- 感染控制 感染控制
- 生物医学工程 生物医学工程
背景情况:
- 手术头盔系统 (SHS) 旨在降低周围假肢关节感染 (PJI) 风险.
- 人们担心,由于SHS的正压,可能会有GGI泄漏,这就造成了PJI风险的矛盾证据.
- SHS和手套管理对GGI泄漏的影响需要进一步调查.
研究的目的:
- 评估外科头盔系统 (SHS) 对手套-长袍接口 (GGI) 泄漏的影响.
- 为了确定手套交换频率和GGI密封对污染风险的影响.
- 提供基于证据的建议,以尽量减少关节塑形术期间的感染风险.
主要方法:
- 使用光凝进行了404次关节整形模拟.
- 测试了四组:使用/不使用SHS (H+/H-) 和密封/不密封GGI (S+/S-).
- 泄漏强度根据暴露时间 (15-60分钟) 和手套交换 (0-6) 量化.
主要成果:
- 在所有组中,泄漏强度随着暴露时间和手套更换频率的增加而增加.
- 使用未密封GGI (H+S-) 的SHS在30分钟和>4次手套交换后显示出最快和最高的泄漏增加.
- 在H+S-中的泄漏与持续时间 (rs = 0.8379) 和频率 (rs = 0.8198) 强烈相关,当SHS缺席或GGI密封时,相关性较弱.
结论:
- 建议在关节整形手术过程中使用SHS进行个人保护.
- 强烈建议密封GGI并每小时进行一次外套更换.
- 这些措施对于减少与SHS使用相关的污染风险至关重要.

Hand hygiene
3.3K
Asepsis is the practice of preventing or breaking the chain of infection. The nurse employs aseptic techniques to prevent the spread of microorganisms and reduce the risk of diseases. Hand hygiene is the cornerstone of aseptic techniques and is classified into medical and surgical asepsis. Medical asepsis includes hand hygiene and the use of gloves. Surgical asepsis, or the sterile technique, refers to practices that render and keep objects and areas free of microorganisms.

Tracheostomy Care II: Procedure
205
Tracheostomy care is an essential nursing skill that involves cleaning and maintaining a tracheostomy tube to prevent infection and other complications. Here's a step-by-step guide explaining each procedure with its rationale. Note that disposable gloves are to be worn at all times and changed as often as needed to maintain a sterile work environment, and to protect both patient and healthcare worker.

Tracheostomy Suctioning I: Pre-Procedural Steps
603
Tracheostomy suctioning is a critical procedure healthcare professionals perform to maintain a patent airway in patients with a tracheostomy tube. This procedure is necessary when secretions accumulate in the airway, causing respiratory distress. Here is a step-wise procedural guide for performing tracheostomy suctioning using an open system.
