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

This was intended a multi-center (2 sites) study that would have shared redacted data with investigators from both sites, however, site #2 did not receive a data sharing agreement or IRB approval from their institution. So by default the study effectively became a single site study.
