Randomized Controlled Trial Comparative Study Clinical Trial
Analgesia for venous cannulation: a comparison of EMLA (5 minutes application), lignocaine, ethyl chloride, and nothing.
Three commonly available local anaesthetics were compared, in a controlled trial, for use before venous cannulation. The pain of application of the local anaesthetic, the pain of cannulation, and the rate of successful cannulations were compared. The value of EMLA cream applied for 5 min was questioned. ⋯ Lignocaine 1%, injected subcutaneously, and ethyl chloride spray significantly reduced the pain of venous cannulation (P < 0.01). The use of lignocaine did not result in significantly more failed cannulations than the control group. It was concluded that local anaesthesia should be used before venous cannulation, even for 20G cannulae.

Cancer registration is an essential element of any cancer control strategy. Data quality is, however, of paramount importance. This paper sets out some of the ways in which the quality of cancer registration data might be improved. In particular, the potential contribution of clinicians and pathologists is highlighted.
