To evaluate pain and discomfort experienced by patients who have uncomplicated cataract extraction using topical anesthesia with no intravenous sedation.
Fichman Eye Center, Manchester, Connecticut.
Blood pressure, heart rate, and respiration were measured preoperatively, during cataract surgery, and postoperatively in 100 randomly selected patients. The average of these measurements (procedural vital) was compared with the blood pressure, heart rate, and respiration levels during surgery.
On average, patients had a negligible increase in blood pressure (1%), a small decrease in heart rate (2%), and a slight decrease in respiration (1%).
Because the vital signs were essentially unchanged during surgery, I believe patients were very comfortable despite having no intravenous sedation.
评估在未使用静脉镇静剂的情况下，采用表面麻醉进行单纯性白内障摘除术的患者所经历的疼痛和不适。
康涅狄格州曼彻斯特的菲克曼眼科中心。
对100名随机选取的患者在术前、白内障手术期间及术后测量血压、心率和呼吸。将这些测量值的平均值（手术关键指标）与手术期间的血压、心率和呼吸水平进行比较。
平均而言，患者的血压仅有可忽略不计的升高（1%），心率略有下降（2%），呼吸稍有下降（1%）。
由于手术期间生命体征基本未变，我认为尽管未使用静脉镇静剂，患者仍非常舒适。
