Abstract
A double-blind study of 229 patients with the use of intravenous diazepam as compared with a placebo to produce sedation during local analgesia showed that significantly improved sedation occurred when diazepam was used. The diazepam was dissolved in cremophor and this reduced the pain of intravenous injection of the diazepam. One patient who received Cremophor only, showed a moderately severe allergic reaction. It is suggested that a small test dose should always be given before giving any drug which is dissolved in Cremophor.
