BackgroundPatients of chronic pain syndromes like fibromyalgia (FMS) when subjected to spinal anesthesia are theoretically more liable to post dural puncture headache (PDPH) as they have enhanced central nervous system sensitization and decreased descending inhibition.ObjectiveThe current study aims to verify the incidence and chronicity of PDPH in FMS patients.Study DesignCase control study.MethodsIn a comparative control study, 70 fibromyalgia patients were scheduled for an elective cesarean delivery fibromyalgia group or Group 1. Group 2 included 70 women scheduled for elective cesarean delivery who had no history of chronic pain and is used as a control group. Both groups were compared regarding the incidence of development of PDPH in the first postoperative 48 hours and the persistence of PDPH for 7 days or more.SettingsWomen's Health Hospital, Assiut University, antenatal Clinic.ResultsThe fibromyalgia group reported more PDPH (18 patients, 25.7%) as compared to the control group (10 patients, 14.3%), P < 0.01. PDPH persisted for 7 or more days in 8 patients in the fibromyalgia group (11.4%) while, it persisted in 2.86% of the control patients. PDPH continued for more than 3 months in 2 patients in the fibromyalgia group (2.86%).LimitationsDifficulty in calculating the dose of analgesics as patients with fibromyalgia may use other analgesics due to musculoskeletal pain.ConclusionDural puncture increases the incidence of PDPH in fibromyalgia patients in comparison with normal controls without increasing other postoperative side effects.
