The usefulness of 10 mg timolol orally as a non-sedative anxiolytic premedicant for day-case patients was examined in a double-blind placebo-controlled study. Patients were invited to take part by letter sent the week before gynaecological (n = 40) or oral (n = 60) surgery was scheduled. Indices of anxiety and alertness were obtained prior to administration of the tablet; quality of previous anaesthetic experience was also recorded. In those patients with no previous or unpleasant previous anaesthetic experience a significant reduction in anxiety amongst those given timolol was identified. Haemodynamic differences between the groups were not clinically significant, and return of psychomotor function was not delayed by timolol. Timolol effectively reduces situational anxiety, is non-sedative, and is advocated as a premedicant for anxious day-case patients and others in whom rapid return of psychomotor function is desirable.
在一项双盲安慰剂对照研究中,对口服10毫克噻吗洛尔作为日间手术患者的非镇静抗焦虑术前用药的有效性进行了检验。通过在安排妇科手术(n = 40)或口腔手术(n = 60)前一周发出的信件邀请患者参与。在服用片剂前获取焦虑和警觉指标;还记录了既往麻醉经历的质量。在那些既往没有或有不愉快麻醉经历的患者中,发现服用噻吗洛尔的患者焦虑显著减轻。两组之间的血流动力学差异无临床意义,噻吗洛尔也未延迟精神运动功能的恢复。噻吗洛尔能有效减轻情境性焦虑,无镇静作用,被推荐作为焦虑日间手术患者及其他希望精神运动功能快速恢复的患者的术前用药。
