title: Paradoxical response to intravenous terbutaline.
abstract: Marked uterine hypertonus was observed in our patient subsequent to the intravenous administration of terbutaline prior to an attempt at external cephalic version. The proximity of hypertonus to terbutaline infusion and the absence of other stimuli suggests that this was a paradoxical response to terbutaline.
