Abstract
OBJECTIVE: To determine whether adding triamcinolone to local anaesthetics increased the efficacy of greater occipital nerve block (GONB) and trigger-point injections (TPIs) for transformed migraine (TM). METHODS:Patients with TM were randomised to receive GONB and TPIs using lidocaine 2% and bupivacaine 0.5% + either saline or triamcinolone 40 mg. We assessed the severity of headache and associated symptoms before and 20 minutes after injection. Patients documented headache and severity of associated symptoms for 4 weeks after injections. Changes in symptom severity were compared between the two groups. RESULTS:Thirty-seven patients were included. Twenty minutes after injection, mean headache severity decreased by 3.2 points in group A (p<0.01) and by 3.1 points in group B (p<0.01). Mean neck pain severity decreased by 1.5 points in group A (p<0.01) and by 1.7 points in group B (p<0.01). Mean duration of being headache-free was 2.7+/-3.8 days in group A and 1.0+/-1.1 days in group B (p = 0.67). None of the outcome measures differed significantly between the two groups. Both treatments were well tolerated. CONCLUSIONS: Adding triamcinolone to local anaesthetics when performing GONB and TPIs was not associated with improved outcome in this sample of patients with TM.
