Five consecutive cases of endophthalmitis that developed after cataract extraction by a single surgeon using the same operating room during one morning session are described. Following preoperative topical administration of ciprofloxacin, surgery consisted of phacoemulsification with peristaltic pump and fluid venting, polymethylmethacrylate intraocular lens implantation, and corneal suture. No complications occurred during surgery. All five patients developed endophthalmitis caused by infection with Alcaligenes xylosoxidans in less than 24 hours. Pulsed-field gel electrophoresis was used to prove similarity between strains. Bacterial inquiry on contamination of the operating room environment revealed massive colonization of phacoemulsifier irrigation channels by Pseudomonas fluorescens bacteria from an unestablished source. Four of the five patients ultimately recovered visual acuity better than 20/60.
本文描述了在一个上午的手术时段内，由同一位外科医生在同一手术室进行白内障摘除术后连续发生的5例眼内炎病例。术前局部应用环丙沙星后，手术包括使用蠕动泵和液体引流的超声乳化术、聚甲基丙烯酸甲酯人工晶状体植入术和角膜缝合术。手术过程中未发生并发症。所有5例患者均在不到24小时内发生了由木糖氧化产碱杆菌感染引起的眼内炎。采用脉冲场凝胶电泳来证明菌株之间的相似性。对手术室环境污染的细菌调查显示来自不明来源的荧光假单胞菌大量定植于超声乳化仪冲洗通道。5例患者中有4例最终视力恢复到优于20/60。
