Randomized Controlled Trial Comparative Study Clinical Trial
Comparison of anxiety before induction of anaesthesia in the anaesthetic room or operating theatre.
Anxiety before induction of anaesthesia was studied in 100 patients who were allocated randomly to one of two groups. Patients in one group were anaesthetised in an anaesthetic room and those in the other group were anaesthetised inside the operating theatre. Both subjective and objective induces of anxiety were used in the comparison. ⋯ There was no significant difference in the level of anxiety between the two groups. The site of induction did not emerge as a major contributory factor to anxiety. The advantages and disadvantages of anaesthetic rooms are discussed.

A case is presented in which asystole and convulsions occurred after an attempted induction of anaesthesia with propofol and fentanyl. The case suggests that a history of syncope may be associated with unusual susceptibility to the bradycardic effects of propofol.

The present study was designed to assess the incidence of pain when methohexitone was administered to 35 depressed patients who had electroconvulsive therapy, and to determine whether the use of lignocaine could modify this, without affecting seizure duration. The same patients were studied during three separate treatment sessions; they received either methohexitone alone or mixed with, or preceded by, lignocaine 10 mg. ⋯ A total of 49% patients reported pain during injection of methohexitone; the use of lignocaine either mixed with, or given prior to, methohexitone significantly reduced this to 23% and 20% respectively (p less than 0.05). Seizure duration was not significantly different during the three treatments.

The development of anaesthetic induction rooms since 1860 to the present day is outlined.

A survey was undertaken to investigate aspects of research work undertaken by junior anaesthetists. Two hundred and ninety-five junior anaesthetists were surveyed. ⋯ Few had received any formal training in research methods. The significance of these findings is discussed with regard to current training opportunities.
