“…Investigations into the effect of propofol on the QT and QTc intervals have yielded contradictory results – McConachie et al 6 . reported that propofol significantly prolonged the QT interval (but to a lesser degree than that seen with thiopentone), whereas Kleinsasser et al 7 .…”

Recent articles have described the increasing frequency of use of propofol as a sedating agent in the ED, and praise the safety profile of propofol when used in this manner. We describe a patient who developed torsade de pointes followed by ventricular fibrillation while undergoing propofol sedation for closed reduction of a mid-shaft fracture of the tibia and fibula. Possible reasons for the event are discussed, and suggestions are made for areas of further research.

“…Thiopental has been reported to prolong the QT interval. 4 Verapamil has been reported to attenuate the posttachycardia QT prolongation. 5,6 It is unlikely that QT prolonged parallel to the QRS morphology changes because of verapamil or thiopental because ECGs were obtained within a few minutes apart.…”

“…18–20 Among the barbiturates, thiopental sodium prolongs QTc in healthy premedicated adults and children. 21 Though QTc is prolonged by pentobarbital, TDR is reduced, reducing arrhythmogenicity. 22 Of the benzodiazepines, midazolam has no effect on QTc.…”
