Cephalalgia is a very common symptom that justifies daily appointment in emergency department.
Analgesic support, and especially use of oxygen and care of associated symptoms as nausea, photophobia or phonophobia, is very dependent on the physician.
The aim of this study is to evaluate the impact of a global analgesic protocol of cephalalgia in emergency department.
The investigators included 200 patients aged of 18 up to 55 years old coming in emergency department for headache. Pain (Visual analogic scale), nausea, photo or phonophobia are recorded each 15 minutes by the patient by using a self-assessment questionnaire. The final diagnosis is recorded by the physician in charge of patient, using International Headache Society criteria.
First 100 patients(group 1) receive usual care.
For the last 100 patients (group 2), physician in charge of patients are incited to use a formal protocol that include: putting the patient in a quiet spot, laying down on a stretcher, providing sound proof helmet and light blocking google, administering oxygen therapy 15 l/min during 15 min, and administering etiological headache adapted medication following learned society guidelines.
Comparison of the data of this 2 groups shall help us to see if the investigators actual analgesic support of cephalalgia is efficient, and if it can be improved by this global analgesic protocol.
