In 60 patients undergoing a curettage in thiopentone induced inhalation anaesthesia with enflurane and N2O/O2 = 2:1, the effects of oral premedication (2 h before anaesthesia) with 30 mg morphine (MST 30) (n = 21), 1 mg lormetazepam (Noctamid) (n = 19) and placebo (n = 21) on psychological (anxiety, depression and asthenia), physiological (blood pressure, heart and respiratory rate) and pain parameters (visual analogue scale, analgesic consumption) were investigated. The study design was single blind, randomized. Before premedication the three groups did not differ in one parameter and so were comparable. MST 30 had a significantly better anxiolytic, Lormetazepam a significantly better antidepressive effect than the compared substance. There were no differences in blood pressure and heart rate. In contrast to lormetazepam and placebo after MST 30 there was no increase in the respiratory rate which can be explained by the anxiolytic stress reducing effect. There was no difference in peri- and intraoperative pain parameters, probably due to the type of surgery. Nausea and vomiting occurred more frequently after MST 30, but there was no significance. A higher rate was probably prevented by the application of transdermal scopolamine the day before surgery. The indication of analgesics (opiates) for premedication is discussed taking the controversy into account. The results of this study show that oral morphine (MST 30) has an anxiolytic effect, one of the most important effects a premedication should have. Further studies should investigate in which types of surgery the analgesic effect of MST 30 is peri- and intraoperatively relevant, so that advantages compared to e.g. Flunitrazepam, Midazolam or Lormetazepam in a higher dosage could be expected.

Of 20 volunteers, five were given intravenous Diazemuls 15 mg over 15 seconds, and three groups of five were given lormetazepam 2 mg intravenously over 10, 20 and 60 seconds, respectively. Laryngeal reactivity and psychomotor function were tested at intervals from prior to injection until 4 hours after injection. For equivalent degrees of depression of psychomotor function, lormetazepam depressed the laryngeal reflex less than Diazemuls (p = 0.004). Lormetazepam give over 60 seconds depressed the laryngeal reflex more than when given over 10 seconds (p = 0.008) or over 20 seconds (p = 0.048), although a significant difference was not demonstrated between the 10-second and 20-second groups. These results concur with experimental evidence that benzodiazepine receptor multiplicity exists, which allows various members of the benzodiazepine group of drugs to exhibit differing therapeutic ratios for their various effects.
