Severe tracheal stenosis and operative delivery.

We report the management of anaesthesia for Caesarean section in a woman with severe extensive tracheal stenosis. Management was initially with spinal anaesthesia, but general anaesthesia became necessary as a result of profuse intra-operative bleeding. We describe the use of the Hayek oscillator cuirass ventilator to allow instrumentation of the larynx whilst maintaining respiratory support, and for weaning from mechanical ventilation.
