Case Reports
Brachial plexus block. Unilateral thoraco-abdominal blockade following the supraclavicular approach.
A supraclavicular brachial plexus block was performed which resulted in unilateral sensory and motor blockade of the thoracic and abdominal walls. General anaesthesia was therefore used and postoperatively it was noticed that analgesia of the upper limb had developed. It is likely that the blockade resulted from an intrapleural injection of local anaesthetic.

Randomized Controlled Trial Clinical Trial
Premedication for day case surgery. A study of oral midazolam.
A double-blind, between-patient trial was used to assess midazolam 7.5 and 15 mg as oral premedication for day case surgery. Midazolam 7.5 mg did not produce significant anxiolysis or sedation in comparison to placebo as measured by patient self-assessment linear analogue scales and observer scores. ⋯ Psychomotor performance assessed by digital-symbol substitution tests was significantly impaired by midazolam, in both doses, throughout the period of investigation. Midazolam 15 mg orally provides good premedication but the prolonged effects make it unsuitable for short-stay patients.
