The study is a single-center, double-blind, randomized protocol comparison. The study will be conducted in Marmara University School of Medicine Pendik Training and Research Hospital, Department of Emergency Medicine between April 2020 and October 2020. The population consists of non-pregnant, adult patients (age of 18 or more) who will be confirmed as migraine according to The International Classification of Headache Disorders 3rd edition (ICHD-3) in the emergency department (ED). After the patient was found suitable for the standard treatment protocol, they will be randomized to receive a 1000 ml bolus of normal saline for 1 hour or normal saline at 10 cc/h for 1 hour. The pain level, functional status, and side effects will be assessed before the beginning, at the 1st hour, 2nd hour and at the 24th hour. The objective of this study is to determine the effect of an intravenous (IV) fluid bolus on migraine headache among patients treated in the ED.
Introduction Headache is a common complaint that is seen in 70-80% of the population and is a common health problem in emergency services. When evaluating the patient with headache, the first step is to determine whether the headache is primary or secondary (1, 2). Primary headaches are classified according to their symptoms and clinical features. Tension-type headache, migraine, and cluster headache are the most common types of primary headaches (3). Secondary headaches can be classified as headaches due to the head and neck trauma, headaches secondary to neurovascular diseases, and headaches due to withdrawal syndromes secondary to drug abuse (4). Migraine is a primary type of headache characterized by recurrent throbbing (usually unilateral) and associated with photophobia, phonophobia, nausea, and other symptoms. Patients with migraine are usually not pleased with the treatment options due to headaches refractory to treatment (5). The current approach to the treatment of migraine headaches consists of two components: treatment of the acute migraine attacks, and prophylactic treatment. According to the World Health Organization (WHO), migraine attacks are the eighth cause of loss of work and performance in the attack period among all lifelong diseases (12). Therefore, effective treatment of migraine attacks is important for the patient and socioeconomic wellbeing of the community. More than 90% of the migraine patients experience acute migraine attacks despite prophylactic treatment and need pain medications (6). Common treatment options used in the ED are phenothiazines (7), serotonin receptor agonists (8), and corticosteroids (9). Headache guideline of the American Academy of Neurology published in 2000 also recommends diclofenac as an effective alternative for the treatment of acute migraine attacks (10, 11). Effective attack therapy has the potential to significantly reduce inefficiency caused by migraine attacks by shortening the duration and reducing the severity of attacks. Although clinical evidence is uncertain, approximately 40% of patients presenting to the ED with a headache are treated with IV fluids (13). Studies with healthy volunteers showed that mild dehydration reduces the pain threshold and increases central pain-related activity in the anterior cingulate cortex, insula, and thalamus (14). Therefore, it is logical to think that dehydration may trigger acute migraine attacks (15). This led to the common approach to use IV fluids besides pain medications in the ED as a routine procedure. A clear benefit would obviously increase the satisfaction of the patient from the ED services, by increasing the pain threshold, decreasing length of stay, and need for rescue treatment. However, on the contrary, IV fluid therapy without an obvious benefit to the patient has a cost burden on the system, uses labor and time of the ED staff, and may increase the duration of the length of stay in the ED. Therefore, the aim of this study is to evaluate the efficacy and side effects related to the addition of 1000 cc bolus NS to the standard treatment of migraine in the ED.

RECRUITINGVAS(headache)
The patient will be asked to place a mark between the 0 and 10 cm points indicated on a 10 cm line, the distance of the marked point to 0 will be taken as the VAS(headache) score in mm.
Time frame: at the 2nd hour
VAS(headache)
The patient will be asked to place a mark between the 0 and 10 cm points indicated on a 10 cm line, the distance of the marked point to 0 will be taken as the VAS(headache) score in mm.
Time frame: at the 1st hour
VAS(nausea)
The patient will be asked to place a mark between the 0 and 10 cm points indicated on a 10 cm line, the distance of the marked point to 0 will be taken as the VASnausea score in mm.
Time frame: at the 1st hour

Successful Treatment
The proportion of patients will successful and failed treatments will be compared between study groups. Successful treatment is defined if VAS(headache) is decreased at least 50% from the highest VAS(headache) reported by the patient at any time-point without the need of additional analgesics and/or antiemetics. Failed treatment is defined if VAS(headache) is decreased not more than 10% from the highest VAS(headache) or patient's declaration that the headache is the same at the 2nd hour. All patients defined as failed treatment will be offered the rescue treatment (analgesic and/or antiemetic).
Time frame: at the 2nd hour
Time-to-discharge
Duration between the time of admission to the emergency department and discharge up to 24 hours.
