Randomized Controlled Trial Clinical Trial
Local anaesthetic: does it really reduce the pain of insertion of all sizes of venous cannula?
The pain of subcutaneous 1% lignocaine injection is significantly less than cannulation pain across all peripheral cannula sizes down to 22-gauge.

Randomized Controlled Trial Comparative Study Clinical Trial
A comparison of the pharmacodynamics of rocuronium and vecuronium during halothane anaesthesia.
Thirty healthy patients were randomised to receive either a single bolus dose of rocuronium 0.6 mg.kg-1 or vecuronium 0.1 mg.kg-1 during halothane anaesthesia. Onset time, duration 25, duration 75 and train-of-four 70 were measured. ⋯ During the first minute following injection of the neuromuscular blocking agent, the heart rate increased by 36% in the rocuronium group but remained stable in those patients who received vecuronium (p = 0.0008). No adverse effects were noted in either group.

Forty anaesthetists, of all grades, were interviewed without prior warning and questioned about the checks they had performed on their anaesthetic equipment before use. The results reveal that a substantial percentage (up to 41%) of anaesthetists perform inadequate checks. Furthermore, of those that do, few follow the Association of Anaesthetists of Great Britain and Ireland's recent guidelines.

This study was designed to evaluate the routine use of a gum elastic bougie for tracheal intubation. The median time to intubation with the gum elastic bougie while simulating an 'epiglottis only' view was only 10 s longer than the time taken during conventional intubation with an optimum view. ⋯ There was no significant difference in the incidence of postoperative sore throat and hoarseness between the two groups. We recommend that anaesthetists should use the gum elastic bougie whenever a good view of the glottis is not immediately obtained.

A case of an anaphylactoid reaction following the induction of anaesthesia is reported. Subsequent intradermal testing suggested propofol to be the causative agent.
