An abscess is a collection of pus that has built up within the tissue of the body. Signs and symptoms of abscesses include redness, pain, warmth, and swelling. The swelling may feel fluid-filled when pressed. The area of redness often extends beyond the swelling. Carbuncles and boils are types of abscess that often involve hair follicles, with carbuncles being larger.
许多人因细菌引起的皮肤感染而前往急诊室。Staphylococcus aureus 是这些感染的主要致病菌,且随着 community-associated methicillin-resistant Staphylococcus aureus (MRSA) 的出现,治疗难度日益增加。 Acute bacterial skin and skin-structure infections are a common reason for seeking care at acute healthcare facilities, including emergency departments. Staphylococcus aureus is the most common organism associated with these infections, and the emergence of community-associated methicillin-resistant Staphylococcus aureus (MRSA) has represented a considerable challenge in their treatment.
根据对抗生素的反应,Staphylococcus aureus 可分为两种类型:methicillin-sensitive Staphylococcus aureus (MSSA) 和 methicillin-resistant Staphylococcus aureus (MRSA)。过去几十年来,随着细菌的进化和抗生素的过度使用,S. aureus 对药物的耐药性不断增加,导致全球 MRSA 感染率上升。 According to the sensitivity to antibiotic drugs, S. aureus can be divided into methicillin-sensitive Staphylococcus aureus (MSSA) and methicillin-resistant Staphylococcus aureus (MRSA). In recent decades, due to the evolution of bacteria and the abuse of antibiotics, the drug resistance of S. aureus has gradually increased, the infection rate of MRSA has increased worldwide.
To review the salient features of the management of severe skin and soft tissue infections (SSTIs), including toxic shock syndrome, myonecrosis/gas gangrene, and necrotizing fasciitis.
脓肿大多由细菌感染引起,最常见的致病菌是耐甲氧西林金黄色葡萄球菌。皮肤脓肿的诊断通常依据外观,并通过切开确认;若诊断不明确,超声成像可能有帮助。对于肛门周围的脓肿,计算机断层扫描 (CT) 在寻找更深层感染时尤为重要。
大多数皮肤或软组织脓肿的标准治疗是切开引流并同步使用抗生素。仅用针抽取脓液通常不足。
皮肤脓肿非常常见,且近年来发病率有所上升。危险因素包括静脉注射毒品,使用者比例报告高达 65%。2005 年,美国有 320 万人因脓肿前往急诊室就诊;2008 年,澳大利亚约有 13,000 人因该情况住院治疗。
○ 治疗
在大多数情况下,单靠非处方药难以治愈脓肿。如出现全身发热、发冷等症状,请尽快就医。
