Sevoflurane anaesthesia with the Komesaroff vaporizer inside the circle system.
This study assessed the safety of sevoflurane anaesthesia using two Komesaroff vaporizers inside the circle with both spontaneous and controlled ventilation. Sevoflurane concentrations were continuously monitored using a mass spectrometer and the anaesthetic depth was easily controlled. ⋯ With continuous monitoring of sevoflurane concentrations, induction and maintenance of anaesthesia using a vaporizer inside the circle is safe during both controlled and spontaneous ventilation. However the high incidence of involuntary movements may limit the feasibility of induction in spontaneously breathing patients.

Cricothyroidotomy and transtracheal high frequency jet ventilation for elective laryngeal surgery. An audit of 90 cases.
We carried out an audit of needle cricothyroidotomy and transtracheal ventilation used during anaesthesia for elective endolaryngeal surgery. The data on 90 consecutive procedures was collected over two years. Patients were anaesthetized using a total intravenous technique. ⋯ There were 12 complications in total. Only three of these were clearly related to the cricothyroid puncture, i.e., one minor bleed and two cases of limited local surgical emphysema. All complications were minor and resolved without sequelae.
