Case Reports
Awake fibreoptic intubation for a rare cause of upper airway obstruction--an infected laryngocoele.
The anaesthetic management of a patient with an infected laryngocoele is presented. The relevance of this condition to the anaesthetist is discussed.

When tracheal intubation is conducted with traditional laryngoscope PtcO2 fall during the first minute after intubation; when continuous O2 supplied laryngoscope (Laryng O2) is used PtcO2 rise; the difference is statistically significant (p less than 0.001) either the subjects are in curarisation apnea or in spontaneous ventilation. With traditional laryngoscope, the fall is faster with spontaneous ventilation conditions than during curarisation apnea. Likewise in normal conscient subject the same fall is faster (p less than 0.001) during first minute of posthyperoxic spontaneous quiet ventilation than the first minute of voluntary hypocapnic apnea induced by hyperventilation during the same hyperoxia. Such results have to be taken into account for the indications of tracheal intubation technical means if hypoxic conditions are to be suspected, particularly for infants and subjects with cardio-respiratory failure.

Case Reports[Obstruction of a naso-tracheal tube by an avulsed nasal concha].
Avulsion of a nasal concha by a nasotracheal tube obstructed the tube in a valvelike manner. The result was increased intrapulmonary pressure, hemodynamic instability, alveolar rupture, pneumomediastinum and pneumoperitoneum without pneumothorax. The case was successfully managed by removal of the nasotracheal tube and immediate oral reintubation.
