TL;DR: The results are interpreted as providing support in a “real life” human stress setting for Gray's neuropsychological model of anxiety in patients referred for surgical removal of impacted third molars.
Abstract: In a randomised, double-blind, parallel groups study, 40 patients referred for surgical removal of impacted third molars received either (a) temazepam 40 mg orally followed at 35 min by IV saline or (b) oral placebo followed by IV diazepam 10 mg (Diazemuls). Patients were divided into High-Anxious and Low-Anxious groups by median split of their anxiety scores on the Speilberger State Anxiety Scale at the time of oral medication. Compared with placebo, temazepam significantly attenuated anticipatory anxiety in the High-Anxious group while in the Low-Anxious group no difference was found between the treatments. Preoperative but not intraoperative heart-rate distinguished between the High-Anxious and Low-Anxious groups and neither oral temazepam nor IV diazepam abolished the heart-rate response to the traumatic stages of the surgical procedure. The results are interpreted as providing support in a “real life” human stress setting for Gray's neuropsychological model of anxiety.

TL;DR: The findings indicate that rapidly acting oral benzodiazepines such as temazepam provide safe, effective alternatives to i.v. diazepam for sedation in outpatients undergoing minor surgical procedures.
Abstract: In a randomized double-blind, parallel groups study, 39 patients underging surgical removal of impacted third molar teeth received either temazepam 40 mg by mouth (as soft gelatin capsules) followed at 35min by i.v. saline, or oral placebo followed at 35 min by i.v. diazepam 10 mg (Diazemuls). Rapid onset of significant anxiolytic activity and psychomotor depression was seen following temazepam, while the pattern and duration of postoperative sedation measured with standard psychometric tests, were similar for both treatments. Ratings by the surgeon and by the patients indicated that sedation following the two treatments was comparable. No significant cardiovascular complications were found with either treatment. The findings indicate that rapidly acting oral benzodiazepines such as temazepam provide safe, effective alternatives to i.v. diazepam for sedation in outpatients undergoing minor surgical procedures.

01 Dec 1986TL;DR: In this paper, the shape control problem for a Sendzimir mill, utilising the As-U-Roll shape actuators, is well understood, and a robustness result for the design is developed, since a single controller must therefore be employed for many different schedules.
Abstract: The solution to the shape control problem for a Sendzimir mill, utilising the As-U-Roll shape actuators, is well understood. The tapered first intermediate rolls, however, provide a more powerful shape control device. This paper describes a control philosophy utilising both the As-U-Rolls and first intermediate rolls as shape control mechanisms. A robustness result for the design is developed, which is useful, since such a mill is normally used to roll a large number of materials, and a single controller must therefore be employed for many different schedules. Finally, a variety of simulation results are presented, showing the transient responses and performance of the multivariable shape control system.
