Background: Perioperative fasting period can be very variable which must be quantified at institutional level so that the institutions can re-formulate their local policies while adapting to updated national and international guidelines. Objective: The purpose of this retrospective study was to ascertain the total duration of perioperative fasting among patients who underwent extracapsular cataract extraction with intraocular lens implantation at the institution during 2016-2022 (a seven-year period). Methods: A query was run by information technology team in the institutional electronic medical records to extract lists of de-identified patients who underwent extracapsular cataract extraction with intraocular lens implantation at the institution during 2016-2022 wherein total perioperative fasting time was calculated from Last Food Intake to In Phase I Time (for solids) and Last Fluid Intake to In Phase I Time (for liquids). Results: Data of 6722 patients was analyzed wherein patients had 4-48 hours of nothing by mouth in terms of fluid perioperatively and 10-48 hours nothing by mouth in terms of food perioperatively. Perioperative fasting durations were in double digits across all age and sex based groups whether it was the mean duration with its confidence limits or median duration with its lower and upper quartiles. Conclusion: Rather than remaining in single digits, perioperative enteral fasting durations were very commonly in double digits at the institution among its patients undergoing extracapsular cataract extraction with intraocular lens implantation.

围手术期肠内禁食持续时间得分达到两位数：一家机构对接受白内障囊外摘除人工晶状体植入术的患者进行的长达七年的横断面回顾

背景：围手术期禁食期可能变化很大，必须在机构层面进行量化，以便机构能够重新制定当地政策，同时适应最新的国家和国际指南。目的：本回顾性研究的目的是确定 2016 年至 2022 年（七年期间）在该机构接受白内障囊外摘除人工晶状体植入术的患者围手术期禁食的总持续时间。方法：信息技术团队对机构电子病历进行查询，提取2016-2022年在该机构接受白内障囊外摘除人工晶状体植入术的去识别化患者名单，其中围手术期总禁食时间根据上次食物计算进入第一阶段时间的摄入量（对于固体）和进入第一阶段时间的最后一次液体摄入量（对于液体）。结果：分析了6722例患者的数据，其中患者围手术期4-48小时禁食，10-48小时禁食。所有年龄和性别组的围手术期禁食持续时间均为两位数，无论是带有置信限的平均持续时间还是带有下四分位数和上四分位数的中位持续时间。结论：在该机构接受白内障囊外摘除人工晶状体植入术的患者中，围手术期肠内禁食时间通常为两位数，而不是保持在个位数。
