title: The use of the Samson modification of the Mapleson 'A' circuit during blind nasal intubation for anaesthesia.
abstract: A technique of blind nasal intubation for anaesthesia using the Samson modification of the Mapleson 'A' circuit is described. Adequate depth of anaesthesia is maintained by continuous insufflation, and scavenging is continuously used to remove waste anaesthetic gases. The position of the tube in relation to the larynx is estimated by movement of the reservoir bag and intermittent condensation of expired water vapour in the clear plastic of the circuit.
