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.
A patient with acute lymphatic leukaemia developed a bilateral fulminating Pseudomonas aeruginosa pneumonia and required controlled ventilation of the lungs. Marked agitation, hypotension and bronchospasm unresponsive to conventional bronchodilators presented a therapeutic challenge. A continuous intravenous infusion of midazolam failed to provide adequate sedation. A continuous intravenous infusion of ketamine resulted in better sedation, an increase in arterial pressure and a diminution of bronchospasm. The clinical improvement was maintained for the 5 days during which ketamine was infused. Plasma concentrations of ketamine and its metabolites are reported.
