AbstractA prospective, randomised study was devised to compare the midline and paramedian approaches to the extradural space in women during labour. The two approaches were equally successful with respect to catheter insertion and analgesia and had a similar incidence of complications, although the paramedian approach caused patients more discomfort. Since only 2 ml of 1% lignocaine with adrenaline were infiltrated prior to insertion of the Tuohy needle, a greater volume of the local anaesthetic may reduce the discomfort of using the paramedian approach.
