Assessing QTc Interval Changes After Droperidol in Emergency Patients

Low-Dose Droperidol and Its Association with QTc Interval Changes in Emergency Department Patients

Observational CHRISTUS Health · NCT06726811

This study is testing if giving low-dose Droperidol to emergency patients affects their heart rhythm by looking at changes in the QTc interval before and after treatment.

What this trial studies

This study aims to evaluate the effects of low-dose Droperidol on QTc interval changes in patients treated in the emergency department. Adult patients aged 18 and older, who are in a cardiac-monitored bed and have an ECG performed, will receive 2.5 mg of IV Droperidol. ECGs will be recorded before and after the administration of Droperidol to assess any significant changes in the QTc interval. The primary outcome is to determine the percentage of patients experiencing a clinically significant increase in QTc after treatment.

Who should consider this trial

Good fit: Ideal candidates include adult emergency department patients aged 18 and older who are in a cardiovascular-monitored bed and have Droperidol ordered.

Not a fit: Patients who are unable to provide consent or have already received Droperidol before the ECG will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide insights into the safety of Droperidol regarding its effects on heart rhythm in emergency department patients.

How similar studies have performed: While there have been studies on Droperidol and QTc intervals, this specific observational approach to assess low-dose effects in an emergency setting is relatively novel.
