Clinical Trial Controlled Clinical TrialEfficacy of lorazepam oral fast dissolving drug formulation (FDDF) in anesthesia premedication in adults: a double-blind placebo controlled comparison.
Lorazepam 4 mg oral fast dissolving drug formulation was compared to placebo in a double-blind study as premedicant in adult anesthesia. Lorazepam induced in this trial a marked relief of anxiety after 60 minutes without changes in vital parameters nor in reflex activity or muscle tonus. Anterograde amnesia was present in about 60 percent of the patients. ⋯ Postoperative residual effects on attention, cognitive, somatic and visceral functions were present till 5 hours postmedication. Lorazepam FDDF (fast dissolving drug formulation) appeared to be an effective and clinically safe premedicant for its good anxiolytic and amnestic effect and its high acceptance by the patients. Its use is not recommended for outpatient anesthesia because it prolongs recovery from anesthesia.

Comparative Study Clinical Trial Controlled Clinical TrialAlizapride in the prevention of postoperative vomiting. A double-blind comparison.
Alizapride 50 mg intravenously was compared with placebo in a double-blind trial on 170 women undergoing planned soft tissue surgery under general anesthesia. Alizapride or placebo was given intravenously about 20 minutes before the end of the operation. A second and a third prophylactic dose was administered 4 and 8 hours after the first injection. ⋯ In the alizapride group there was less retching or emesis than in the placebo-group and the difference was statistically significant. However, there was still a significant incidence of 34% of postoperative vomiting in the alizapride group. There were no effects on heart rate or on respiratory rate but small changes of blood pressure after the first and second prophylactic injection of alizapride have been noted.

ReviewNo decisive break-through yet for general anesthesia combined with locoregional anesthesia!
Although on theoretical grounds locoregional anesthesia, because of the claimed suppression of stress response and the ease with which prolonged analgesia can be achieved, seems preferable to general anesthesia, the shortcomings and drawbacks are such that its use is restricted to well chosen indications. The hope that combination anesthesia can overcome the limitations of both techniques remain to be proven whereas the problems that can arise during the combined technique could pose a major threat to the patient.
