摘要目的:探讨前馈控制对飞秒激光辅助白内障手术取消率的影响。方法:采用便利抽样法，2018年3月—2019年3月，选取在首都医科大学附属北京同仁医院白内障手术室进行飞秒激光辅助白内障手术的患者为研究对象。将2018年3—9月进行飞秒激光辅助白内障手术的267例患者作为对照组，将2018年10月—2019年3月进行飞秒激光辅助白内障手术的319例患者作为观察组。对照组患者实施白内障日间手术常规护理模式。观察组在常规护理的基础上增加前馈控制管理。比较两组患者当日手术取消率及患者满意度。结果:观察组患者当日手术取消率为4.1%（13/319）；对照组当日手术取消率为14.2%（38/267），两组比较差异有统计学意义（χ 2=17.615， P<0.01）。观察组患者满意率为97.3%（288/296），对照组患者满意率为92.1%（222/241），差异有统计学意义（χ 2=7.468， P<0.01）。 结论:将前馈控制应用于眼科日间飞秒激光辅助白内障手术中，可有效降低患者当日手术取消率，减少医院资源的浪费，提高患者满意度。

abstractsObjective:To explore the effects of feedforward control on cancellation rate in femtosecond laser assisted cataract surgery.Methods:From March 2018 to March 2019, we selected patients with femtosecond laser assisted cataract surgery in Cataract Operating Room at Beijing Tongren Hospital of Capital Medical University as subjects by convenience sampling. A total of 267 patients with femtosecond laser assisted cataract surgery from March 2018 to September 2018 were in control group; a total of 319 patients with femtosecond laser assisted cataract surgery from October 2018 to March 2019 were in observation group. Patients of control group carried out routine nursing for cataract day surgery. On the basis of that in control group, observation group implemented feedforward control management. We compared the day's surgery cancellation rate and patient satisfaction of between two groups.Results:On the same day, the surgery cancellation rates of patients of observation group and control group were 4.1% (13/319) and 14.2% (38/267) with a statistical difference (χ 2=17.615, P<0.01) . The patient satisfaction of observation group and control group was 97.3% (288/296) and 92.1% (222/241) with a statistical difference (χ 2=7.468, P<0.01) . Conclusions:Application of feedforward control in femtosecond laser assisted cataract day surgery of Ophthalmology Department can effectively reduce the day's surgery cancellation rate and hospital waste of resources, and improve patient satisfaction.
