まとめ

神経血管外科手術後の手術部位感染 (SSI) は,患者の2. 1%で発生しました. 最も一般的な病原体として,手術後の平均診断期間は29日でした.

科学分野:

神経外科
感染症
公衆衛生

背景:

手術部位感染 (SSI) は神経外科患者の罹病率の重要な原因です.
神経血管疾患に対する頭蓋骨切除後のSSI発生に関するデータは限られている.

研究の目的:

頭蓋内神経血管外科手術後のSSIの発生率と特徴を決定する.
診断までの時間,重症度,およびこれらの感染に伴う一般的な病原体について分析する.

主な方法:

頭蓋内神経血管外科手術を受けた1065人の連続した患者の遡及分析 (2013年−2022年).
収集されたデータには,人口統計,危険因子,治療,入院が含まれています.
クラヴィエン・ディンドのグレードを用いてSSIの影響を分類し,修正までの時間,微生物,病理を分析した.

主要な成果:

全体のSSI発生率は2. 1% (34例) であった.
主要な病原体はStaphylococcus epidermidis (32%) とStaphylococcus aureus (22%) でした.
インデックス処置から外科的傷口修正までの平均時間は27. 5日でした.

結論:

このコホートにおけるSSIの発生率は2. 1%で,傷の修正までの平均時間は29日でした.
これらの発見は,神経血管外科における術後の感染を減らすための戦略を開発するための基準となる.

Factors Affecting the Risk of Infection

12.3K

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...

Healthcare Associated Infections I: Iatrogenic, Exogenic and Endogenic

4.4K

Healthcare-associated infections (HAIs) occur in a healthcare facility while a person receives care for another ailment. This category also includes work-related infections among healthcare staff.
HAIs significantly increase the cost of health care. Extended stays in healthcare institutions, increased disability, increased costs of medications, including specialized antibiotics, and prolonged recovery times add to the patient's expenses and the healthcare institution and funding bodies.

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.
The best practices for preventing healthcare-associated infections include hand hygiene, patient risk...
