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.

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

The authors have examined early records of the administration of ether anaesthesia in Manchester and the lives of several medical men involved in these events. Charles Strange, a dentist and chemist, in a letter to the Manchester Guardian published on 14 January 1847, described a self-administration of ether for dental extraction, but George Bowring, a surgeon, subsequently claimed the first anaesthetic administered by a doctor in Manchester. The merits of these claims are discussed in the light of the circumstances surrounding these events.
