title: Torsades de Pointes associated with intravenous haloperidol in critically ill patients.
abstract: In this retrospective case-control study, 8 of 223 consecutive patients (3.6%) treated with intravenous haloperidol developed torsades de pointes, and were compared with 41 patients randomly selected as controls. The likelihood of torsades de pointes associated with intravenous haloperidol is significantly greater in patients receiving > or = 35 mg over 24 hours or in those with a QTc interval of >500 ms, or both.
