目的 觀察酮咯酸氨丁三醇注射液用于無痛胃鏡檢查超前鎮(zhèn)痛的臨床效果。方法 選擇2010年10月—2011年10月保定市急救中心無痛胃鏡檢查患者120例，隨機分為觀察組和對照組，觀察組60例，術(shù)前30 min im酮咯酸氨丁三醇注射液60 mg；對照組60例，術(shù)前未用任何鎮(zhèn)痛藥。比較兩組患者術(shù)前、術(shù)中、術(shù)后的血壓（SBP）、心率（HR）、血氧飽和度（SPO2）、睫毛反射消失時間、術(shù)中不適情況、術(shù)畢清醒時間、丙泊酚總用量。結(jié)果 觀察組術(shù)中SBP和HR的波動小于對照組；觀察組丙泊酚總用藥量及術(shù)中不適發(fā)生例數(shù)均小于對照組；觀察組睫毛反射消失時間及清醒時間較對照組縮短，以上指標兩組比較差異均有顯著性（P＜0.05）。結(jié)論 酮咯酸氨丁三醇注射液用于無痛胃鏡超前鎮(zhèn)痛檢查效果滿意，可降低術(shù)中不適的發(fā)生率，減少丙泊酚用量，縮短蘇醒時間。

Objective To observe the effects of ketorolac tromethamine injection used for preemptive analgesia of painless gastroscopy application. Methods One hundred and twenty patients in Baoding Emergency Center from October, 2010 to October, 2011 treated with painless gastroscopy were randomly divided into the observation and control groups, each group of 60 cases. Observation group was im injected ketorolac tromethamine injection 60 mg 30 min before operation; No any analgesics was used in the control group. The patients in the two groups were compared with preoperative, intraoperative, postoperative systemic blood pressure (SBP), heart rate (HR), oxygen saturation (SPO2), eyelash reflex lossing time, surgery discomfort, sober time of surgery, and propofol total amount during preoperation, intraoperation, and postoperation. Results SBP and HR fluctuations in the observation group were less than those in the control group; Propofol dosage and intraoperative discomfort cases in the observation group were less than the number of cases occurred in the control group; A set of eyelash reflex lossing time and sober time in the observation group was shorter than those in the control group. The above two indicators were statistical significance between the two groups (P＜0.05). Conclusion Ketorolac tromethamine injection used for preemptive analgesia of painless gastroscopy showed the satisfied treatments and could decrease the incidence of intraoperative discomfort, reduce the dosage of propofol, and shorten the sober time.
