Oxygen in Migraine Treatment

IIn this study, the investigators planned to investigate effectiveness of supplemental oxygen in patients (18-65 years) who were diagnosed as headache related to migraine without aura in the emergency department (ED). Patients who will be ordered standard migraine therapy (50 mg dexketoprofen and 10 mg metoclopramide HCl in 100 cc normal saline IV) by the physician blind to research, will be evaluated by the researchers before the treatment and patients met the study criteria will be included. Included patients randomly divided to two group, study group will receive supplemental oxygen with face mask for 1 hour. Patients' visual analog score (VAS) will be measured at 0th, 15th, 30th and 60th minute of treatment. If there will not be a 50% decrease at VAS score from the beginning, patients will be examined again by the physician again. Patients who will be ordered 100 mg tramadol as rescue therapy by the physician, will be continued to observed, VAS scores will be measured at 120th minute again. To avoid drug related bias, patients who will be ordered any other drug for primary care or rescue treatment other than mentioned above will not be included into the study.
