Training, skills and approach to potentially difficult anaesthesia in general practitioner anaesthetists.
Seventy-six of the 92 practising South Australian rural general practitioner anaesthetists responded to a questionnaire on anaesthetic training, skills and approach to potentially difficult anaesthesia. The mean training period in anaesthesia was 7.5 months, 24% at registrar level. Eight per cent had no training, and 40% had 3 months or less. ⋯ Patients classified as ASA grade 3 to 5, disease states such as unstable angina, severe asthma, and risk factors such as skeletal myopathy, were avoided by most general practitioners. The failed intubation rate was 50/10,000. The conclusion is that South Australian general practitioner anaesthetists exhibit a generally safe approach to selection of patients for anaesthesia, although in some instances the approach to potentially difficult anaesthesia should be more conservative.

Comparative StudyThe incendiary characteristics of the laryngeal and reinforced laryngeal mask airway to CO2 laser strike--a comparison with two polyvinyl chloride tracheal tubes.
The incendiary characteristics of the laryngeal and reinforced laryngeal mask airway to the CO2 laser have been compared with two polyvinyl chloride tracheal tubes. Three different power densities (2.35, 4.7 and 9.8 x 10(3) watt/cm2) were used, with either oxygen or a 30% oxygen/70% nitrous oxide mixture flowing down the tube. The laryngeal mask airway (and reinforced model) was shown to be more resistant than the polyvinyl chloride tracheal tubes. ⋯ At this power density the polyvinyl chloride tube ignited in 2 to 8 seconds and the cuff was penetrated in 0.1 seconds. At the highest power density the tubes of all airways ignited within 0.2 seconds. The possibilities for improving the incendiary characteristics of the laryngeal mask airway are discussed.
