Abstract

We have studied the effects of choice of local anaesthetic and temperature of extradural injectate on speed of onset of sensory block for elective extradural Caesarean section in a double-blind trial in 120 women allocated randomly to one of four groups to receive either plain 0.5% bupivacaine or 2% lignocaine with 1:200000 adrenaline at either room temperature or 38°C. The onset time of lignocaine with adrenaline was shorter than that of bupivacaine regardless of temperature (P < 0.01). Warmed lignocaine produced the most rapid block overall (P < 0.025). The incidence of hypotension, ephedrine requirement, shivering, quality of analgesia and additional analgesic requirements were similar for all groups.
