The CHECK Trial: A Comparison of Headache Treatment in the ED: Compazine Versus Ketamine

The Check Trial: A Comparison of Headache Treatment in the ED: Compazine Versus Ketamine. A Multi-Center, Randomized Double-Blind, Clinical Control Trial.

This study compares the efficacy of low dose Ketamine versus Compazine for the control of headache in patients presenting to the Emergency Department.

Study Overview

Detailed Description

After enrollment, each patient will randomized either to the standard treatment arm to receive prochlorperazine 10 mg IV along with diphenhydramine 25 mg IV, OR to the study arm to receive Ketamine 0.3 mg/kg along with ondansetron 4 mg IV. The diphenhydramine or ondansetron will be administered first, and immediately afterward the prochlorperazine or Ketamine will be administered. The prochlorperazine or Ketamine will be diluted in saline so that the total volume is 5 mL, and will be administered over 2 minutes. The diphenhydramine will be diluted in saline so that it is 2 mL (the same volume as the ondansetron). Both groups will also receive a 500 mL normal saline bolus after the study medications are administered. The ED pharmacist will be responsible for preparing the medications, using a double-blind protocol. He or she will record which arm the patient was randomized to. Only the pharmacist will have access to the randomization records and will not reveal the randomization until the end of the study. Emergency providers will be instructed not to administer any rescue medications for at least 30 minutes. The electronic medical record order will read "randomized study medication" (for the Ketamine or prochlorperazine) and "randomized add-on medication" (for the ondansetron or diphenhydramine).

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Headache Following Intervention
Time Frame: 0-60 minutes
Reduction in 100 mm Visual Analog Scale (VAS) Score. Positive values represent a reduction in headache severity. The maximum possible change in VAS score is 100 mm, representing the complete relief of a maximally severe headache. A change of 0 mm corresponds to no change in headache severity, and a negative value indicates worsening of the headache after the medication.
0-60 minutes

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Anxiety
Time Frame: 0-60 minutes
Reduction in 100 mm Visual Analog Scale (VAS) Score. The maximum possible change in VAS score is 100 mm, representing the complete relief of maximum anxiety. A change of 0 mm corresponds to no change in anxiety level, and a negative value indicates worsening of the anxiety after the medication.
0-60 minutes
Nausea
Time Frame: 0-60 minutes
Reduction in 100 mm Visual Analog Scale (VAS) Score. The maximum possible change in VAS score is 100 mm, representing the complete relief of maximum nausea. A change of 0 mm corresponds to no change in nausea level, and a negative value indicates worsening of the nausea after the medication.
