The aim of this study is to evaluate the short-term clinical efficacy of GON anaesthetic blockades in chronic migraine and to analyze their effect on pressure pain thresholds (PPTs) in different areas. We hypothesize that those patients receiving real GON anesthetic blockade will receive greater improvements in pain nociception. We will conduct a double-blind, randomized, parallel and placebo-controlled clinical trial where one group will be treated with bilateral GON blockade with bupivacaine 0,5% and the other group will be treated with placebo.'}, 'eligibilityModule': {'sex': 'FEMALE', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '65 Years', 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Chronic migraine\n\nExclusion Criteria:\n\n* Other primary headaches\n* Other secondary headaches\n* Co-morbid medical diseases'}, 'identificationModule': {'nctId': 'NCT02188394', 'briefTitle': 'Anesthetic Blockades and Migraine', 'organization': {'class': 'OTHER', 'fullName': 'Universidad Rey Juan Carlos'}, 'officialTitle': 'Effects of Anesthetic Blockades on Pain Modulation in Migraine', 'orgStudyIdInfo': {'id': 'HCSC11/263'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'EXPERIMENTAL', 'label': 'Anesthetic blockades with bupivacaine', 'description': 'Patients will receive a bilateral greater occipital nerve blockade with bupivacaine 0,5%', 'interventionNames': ['Drug: Anesthetic blockades with bupivacaine']}, {'type': 'PLACEBO_COMPARATOR', 'label': 'Isotonic saline injection', 'description': 'Patients will receive a bilateral occipital injection with isotonic saline', 'interventionNames': ['Drug: Isotonic saline injection']}], 'interventions': [{'name': 'Anesthetic blockades with bupivacaine', 'type': 'DRUG', 'armGroupLabels': ['Anesthetic blockades with bupivacaine']}, {'name': 'Isotonic saline injection', 'type': 'DRUG', 'armGroupLabels': ['Isotonic saline injection']}]}, 'contactsLocationsModule': {'locations': [{'city': 'Madrid', 'state': 'Madrid', 'country': 'Spain', 'facility': 'Hospital Universitario Clinico San Carlos-Universidad Complutense de Madrid', 'geoPoint': {'lat': 40.4165, 'lon': -3.70256}}], 'overallOfficials': [{'name': 'Maria Luz Cuadrado, MD; PhD', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': 'Hospital Clinico San Carlos-Universidad Complutense de Madrid'}]}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'César Fernández-de-las-Peñas', 'class': 'OTHER'}, 'responsibleParty': {'type': 'SPONSOR_INVESTIGATOR', 'investigatorTitle': 'Proffesor', 'investigatorFullName': 'César Fernández-de-las-Peñas', 'investigatorAffiliation': 'Universidad Rey Juan Carlos'}}}}
