| Scientific title | Fixed-time chlorazepate dipotassium premedication versus midazolam on demand: a randomised, controlled trial |
| Study acronym | premedication |
| Study objectives | We hypothesised that: 1. 50 mg chlorazepate dipotassium at 10 pm evening before surgery prevent an increase of anxiety and sympatho-adrenal activity at morning of surgery sufficiently, and 2. A fixed-time application of chlorazepate dipotassium at 7 am morning of surgery may be superior compared to administration of midazolam 30 minutes prior to induction of anesthesia with respect to level of anxiety, sympatho-adrenal activity and conscious sedation. |
| Ethics approval(s) | The trial was approved by the local ethics committee of the University Kiel on the 3rd April 2002 (reference number: AZ 142/01). |
| Health condition(s) or problem(s) studied | Premedication, Anaesthesia |
| Intervention | Patients were randomised to one of two groups: 1. Group CCP: at Evening Before Surgery (EBS) clorazepate dipotassium 50 mg orally (Tranxilium®; Sanofi-Aventis GmbH, Frankfurt am Main, Germany); at Morning Of Surgery (MOS) clorazepate dipotassium 25 mg orally; and before Induction of Anesthesia (AI) placebo orally 2. Group CPM: at EBS clorazepate dipotassium 50 mg orally; at MOS placebo orally; before AI midazolam 7.5 mg orally (Dormicum®; Roche, Mijdrecht, The Netherlands) Dosages of clorazepate dipotassium in our study were based on recommendations that have been published previously. |
