概括
对于耳植入器的单剂量抗生素预防,在预防术后伤口感染方面,与长期治疗一样有效. 这一发现表明,较短的抗生素持续时间可能是足够的,可能减少在接受耳植入器手术的患者中不必要的抗生素暴露.
科学领域:
- 耳鼻喉科 耳鼻喉科 耳鼻喉科
- 预防传染病 预防传染病
- 手术场所感染控制手术场所感染控制
背景情况:
- 耳植入后的术后伤口感染,虽然很少见,但可能很严重,需要装置扩展.
- 通常建议进行外科手术期间的抗生素预防,但有关其类型和持续时间的做法在各机构之间存在很大差异.
研究的目的:
- 评估不同外科手术期间抗生素预防策略在预防耳植入后并发症的有效性.
- 为了确定是否单次注射抗生素在减少术后伤口感染方面不劣于长期抗生素治疗.
主要方法:
- 在2007年至2019年间接受了耳植入器的700名患者的回顾性分析.
- 在手术后28天内评估伤口感染,分类为重大或轻微的并发症.
- 在接受一次性,48小时或>72小时抗生素预防的患者中比较感染率.
主要成果:
- 在记录了抗生素数据的670名患者中,10%接受了单次注射,23.6%接受了48小时,66.4%接受了超过72小时的预防.
- 总体而言,9.5%的患者经历了伤口并发症,主要感染率为1.6%.
- 在单次注射,48小时和长期抗生素组之间没有观察到伤口感染率的统计学上显著差异 (p=0.46).
结论:
- 与延长抗生素治疗相比,单剂量抗生素预防似乎没有显著增加术后伤口感染的风险.
- 这些发现表明,单次抗生素剂量可能足以预防耳植入后手术部位感染.
- 建议继续收集多中心数据,以进一步验证这些结果,并完善抗生素预防指南.

Factors Affecting the Risk of Infection
The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin create...

Healthcare Associated Infections II: Preventive Measures
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.

Clinical Significance of Antibiotic Resistance
Methicillin-resistant Staphylococcus aureus (MRSA) presents a critical public health threat, arising from its capacity to resist β-lactam antibiotics due to acquisition of the mecA gene within the staphylococcal cassette chromosome mec (SCCmec). This gene encodes penicillin-binding protein 2a (PBP2a), which impairs binding efficacy of methicillin and other β-lactams. MRSA has evolved into distinct clonal lineages impacting humans and animals alike, reinforcing its significance within the One...
