Abstract Five hundred members of the Obstetric Anaesthetists Association were surveyed regarding their technique for identification of the epidural space. Eighty-one per cent of the questionnaires were returned completed. Fifty-nine per cent of respondents first learned a loss of resistance to air technique, 33.4\% to saline and 7.4\% another technique. Presently, 37.1\% and 52.7\% use only a loss of resistance to air or saline, respectively. Six per cent use both techniques and 3.2\% use other techniques. Twenty-eight per cent taught a loss of resistance to air, 57.2\% taught a loss of resistance to saline and 12.9\% taught both techniques. Twenty-three per cent changed from a loss of resistance to air, to a saline technique, and 4.2\% vice versa. Forty-seven per cent of those using air felt that loss of resistance to air was not associated with a clinically significant difference in the incidence of accidental dural puncture compared with saline.
