 In this prospective, randomised, controlled, double-blind study; parturients with functioning labour epidural analgesia requiring conversion to anaesthesia for surgical delivery SD - will be randomised into control and intervention groups: room temperature RT and body temperature BT. The control group RT will receive room temperature Ropivacaine 0.75, as is the standard practice. The treatment group BT will receive 0.75 Ropivicaine warmed up to 37C temperature. Block height will be assessed every 2 minutes by a blinded investigator until the loss of sensation to cold at the level of T4, sensation to touch will be used as second modality.
