概括
在脊椎外科手术中,手术期间的抗生素灌效果有限. 亨塔米辛抑制了Pseudomonas aeruginosa,但万科米辛和塞法索林并没有显著抑制其他常见的病原体.
科学领域:
- 微生物学 微生物学
- 传染性疾病 传染性疾病
- 手术创新 在外科创新.
背景情况:
- 在脊椎外科手术中,为预防感染,手术期间的抗生素灌是常见的.
- 支持其有效性的证据有限,特别是在仪器仪表方面.
- 这项研究研究了抗生素对常见的手术部位感染病原体的疗效.
研究的目的:
- 评估短期抗生素暴露对常见伤口病原体的体外效应.
- 确定抗生素暴露的最佳持续时间,以消灭手术部位感染生物.
- 评估万科米辛,甘他米辛和塞法林对金黄色葡萄球菌,表皮葡萄球菌和 Pseudomonas aeruginosa 的有效性.
主要方法:
- 未来的体外试验研究设计.
- 微生物悬浮剂 (金黄色葡萄球菌,皮肤上的葡萄球菌,Pseudomonas aeruginosa) 暴露于万科米辛,珍塔米辛或塞法索林.
- 抗生素暴露持续时间为5分钟和8小时,其次是洗.
- 使用激光光散射技术监测微生物生长.
主要成果:
- 根塔米辛在5分钟和8小时暴露后完全抑制了Pseudomonas aeruginosa的生长.
- 没有观察到 Staphylococcus aureus 或 Staphylococcus epidermidis 与任何测试的抗生素 (万科米辛,珍塔米辛,塞法索林) 具有显著的细菌生长抑制.
- 对照组和大多数细菌-抗生素组合显示出类似的生长曲线,表明缺乏疗效.
结论:
- 在模拟的手术场所灌场景中,甘他素对 Pseudomonas aeruginosa 有效.
- 范科米辛和塞法索林对测试的格兰阳性病原体 (金黄色葡萄球菌,表皮葡萄球菌) 的疗效有限.
- 需要进一步的研究来确定有效的抗生素策略,以在脊柱手术中全面预防手术部位感染.

Hand hygiene
3.1K
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.

Local Anesthetics: Clinical Application as Spinal Anesthesia
552
Spinal anesthetics are given during lower abdomen and limb surgeries to block sensory and motor neurons. They are administered in the mid to low lumbar regions, primarily acting on the cauda equina's nerve roots. The blockade level depends on the local anesthetic (LA) concentration. Usually, low LA concentrations are sufficient to block sensory fibers, while only high LA concentrations block motor fibers. Other factors like injection volume and speed, the patient's posture, and the drug...
