Anaesthesia
-
One hundred and sixty six patients were questioned by means of a multiple choice questionnaire, to determine their knowledge of peri-operative care, anaesthesia and the rôle of anaesthetists. In general, knowledge was good, but there were some important misconceptions; in particular, 28.3% of respondents thought that fasting referred to food only, and not to fluid intake. In addition, 47.6% of respondents considered pain to be a necessary part of the healing process and 38.6% believed that it was something that just had to be endured. When forthcoming anaesthesia is discussed, anaesthetists need to ascertain that patients really do understand the language used.

Clinical Trial Controlled Clinical Trial
Sensitivity to second dose of mivacurium.
The sensitivity of patients to a second dose of mivacurium has been studied following complete recovery of the twitch response after > 95% neuromuscular block produced by a systemic bolus of the drug. In further experiments we have excluded one arm from the effect of a systemic bolus ED95 dose of mivacurium for 100 s so as to obtain two different levels of neuromuscular block in the two arms of the same patient. ⋯ A similar increase in sensitivity was observed in the arm that had been excluded for 100 s from the peak effect of the drug. It was concluded that the second dose sensitivity was not due to a receptor effect or to residual drug in plasma.

Case Reports
Emergency intubation through the laryngeal mask airway. The effective application of cricoid pressure.
A patient with Kugelberg-Welander disease presented as an unexpected difficult intubation. Tracheal intubation was achieved through the laryngeal mask airway, while regurgitation was prevented with continuous cricoid pressure. Regurgitation occurred after cricoid pressure was released.
