To review the clinical and microbiologic features of isolates among patients with puerperal mastitis requiring hospitalization.
Between January 2000 and December 2008, postpartum patients who were hospitalized for mastitis were enrolled. The clinical characteristics, microbiologic results, management, and outcomes were reviewed.
One hundred twenty-seven cases were enrolled. Seventy-six patients (59.9%) underwent incision and drainage for abscess drainage, all of whom discontinued breastfeeding. Staphylococcus aureus and coagulase-negative staphylococci were the most common isolates. Among 81 isolates of S aureus, 52 (64.2%) were resistant to oxacillin. Patients undergoing incision and drainage were more likely to discontinue breastfeeding, had a longer duration of symptoms, a longer hospitalization, a higher platelet count and higher rates of infection caused by S aureus and oxacillin-resistant S aureus.
Oxacillin-resistant S aureus has emerged in patients with puerperal mastitis during the past decade, and often necessitates incision and drainage, which results in discontinuation of breastfeeding.
回顾需要住院治疗的产褥期乳腺炎患者的临床和微生物学特征。
2000 年 1 月至 2008 年 12 月，我们对因乳腺炎住院的产后患者进行了研究。回顾了患者的临床特征、微生物学结果、治疗方法和转归。
共纳入了 127 例患者。76 例（59.9%）患者接受脓肿切开引流，均停止了母乳喂养。金黄色葡萄球菌和凝固酶阴性葡萄球菌是最常见的分离菌。在 81 株金黄色葡萄球菌中，52 株（64.2%）对苯唑西林耐药。接受切开引流的患者更可能停止母乳喂养，症状持续时间更长，住院时间更长，血小板计数更高，金黄色葡萄球菌和耐苯唑西林金黄色葡萄球菌引起的感染发生率更高。
在过去十年中，产褥期乳腺炎患者中出现了耐苯唑西林金黄色葡萄球菌，常需要切开引流，这导致母乳喂养的停止。
