Brief summary

We intend to assess the effects of negative suggestion / communication styles on the patient's perception of pain and anxiety during subsequent multiple painful procedures (Local anaesthetic injection, IV cannulation and combined spinal epidural insertion). We will compare these outcomes with the effects that positive suggestion / communication styles has on perception of pain and anxiety during subsequent multiple painful procedures (local anaesthetic injection, IV cannulation and epidural insertion). Null hypothesis = negative or positive styles of communication before painful procedures will have no effect on patient's perception of pain and anxiety during subsequent multiple painful procedures.

Interventions

Negative suggestion - prior to inserting an intra-venous cannula, the patient will have local anaesthetic injected at the site of insertion subcutaneously and will be told that this will be painful in itself. This negative suggestion will be repeated prior to insertion of the IV cannula, and prior to the subsequent insertion of local anaesthetic at the insertion site of the combined spinal epidural (CSE), and prior to the insertion of the CSE itself. Pain and anxiety scores will be assessed afte
