Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Hypothesis Our study is designed to test the null hypothesis that there will be no clinically significant change in QTc interval after administration of 2.5mg of IV Droperidol during an emergency department visit.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
These post-droperidol ECGs will not be stored in the electronic medical record nor read by a physician in real time. Treatment decisions regarding the patient's medical care in the ED will not be affected by these second ECGs; decisions about whether other ECGs may be needed will be made by the treating physician. The primary study outcome will be the percentage of the study population who experience a clinically significant increase in QTc after low-dose droperidol administration, defined as an increase in QTc of 20 ms or greater. Secondary outcome measures will be the mean change in QTc across the study population, and the percentage of the study population for whom the administration of low-dose droperidol is associated with an increase in QTc that re-classifies them as having a prolonged QTc (\>450 ms in men and \>470 ms in women).
