A placebo controlled randomized double blind study was designed to assess the suitability of oral Midazolam as a premedication in day care surgery in adult Pakistani patients. Fifty ASA I and II patients aged between 20-60 years received either Midazolam 7.5 mg or a placebo approximately one hour prior to surgery. Midazolam 7.5 mg produced significant anxiolysis and sedation (p < 0.001) in comparison to placebo after one hour of premedication. There was a significant difference (p < 0.001) in the mean heart rate and blood pressure in both groups after 1 hour of premedication with a lesser rise in blood pressure and heart rate in the Midazolam group. Psychomotor performance assessed by 'n' deletion test was impaired by Midazolam (p < 0.001) and recall of pictures revealed differences (p < 0.05) in the groups at one hour after premedication. However, at four hours after surgery there were no differences in both groups. These findings indicate that rapidly acting oral Midazolam in doses of 7.5 mg provided safe and effective premedication in terms of anxiolysis, sedation, amnesia and psychomotor performance and is suitable for day surgery.
一项安慰剂对照的随机双盲研究旨在评估口服咪达唑仑作为成年巴基斯坦患者日间手术术前用药的适用性。50名年龄在20至60岁之间的ASA I级和II级患者在手术前约一小时接受了7.5毫克咪达唑仑或安慰剂。用药一小时后,与安慰剂相比,7.5毫克咪达唑仑产生了显著的抗焦虑和镇静作用(p < 0.001)。用药1小时后,两组的平均心率和血压存在显著差异(p < 0.001),咪达唑仑组的血压和心率升高幅度较小。通过“n”删除试验评估的精神运动表现受到咪达唑仑的损害(p < 0.001),用药一小时后两组在图片回忆方面存在差异(p < 0.05)。然而,术后四小时两组之间没有差异。这些发现表明,7.5毫克剂量的速效口服咪达唑仑在抗焦虑、镇静、遗忘和精神运动表现方面提供了安全有效的术前用药,适用于日间手术。
