A placebo controlled trial of glyceryl trinitrate was carried out in women whose first attempt at external cephalic version without tocolysis had been unsuccessful. No significant differences between groups were found and no side effects were noted. It is recommended that a larger, possibly multicentre study, should be undertaken.
