Acute infective airway obstruction associated with subglottic stenosis.
Pre-existing subglottic stenosis in a 22-month-old child with laryngotracheobronchitis resulted in failure to intubate the trachea on the intensive therapy unit. Tracheostomy was necessary in the operating theatre to secure the airway. The implications for safe management are discussed.

Equipment Failure↗
A modified expiratory valve for teaching.
The shrouding of anaesthetic expiratory valves prevents the anaesthetist from either seeing valve disc movement or hearing clearly the escape of gas during expiration. A modification to one type of valve (Medishield II) is described which replaces this lost information by providing a direct indication of valve opening.

A new dual function nerve stimulator.
The Duostim model TV02 is a new peripheral nerve stimulator designed both for nerve identification in the performance of regional anaesthesia and for monitoring neuromuscular blockade. The output pulses are unipolar and of adjustable constant current. The provision of single twitch (1 Hz and 1/15 Hz) train-of-four and tetanic stimuli, together with indication of the current delivered and the small size of the unit, facilitate its clinical use. Performance was assessed and found to be according to specification.
