Objective: To assess the efficacy of greater occipital nerve (GON) block in treatment and prevention of chronic migraine.
Study Design: Quasi-experimental study.
Place and Duration of Study: Department of Anesthesia, Combined Military Hospital, Rawalpindi Pakistan, from May to Oct 2023.
Methodology: A total of 50 patients with chronic migraine fulfilling our inclusion criteria were randomly divided into two groups, i.e. Group-O (received GON block) and Group-C (managed with pharmacological therapy). Patients were followed over a period of 3 months. The grading of pain was done with the help of visual analogue score (VAS) into no pain, mild pain, moderate pain and severe pain. The frequency of different pain grades and patient satisfaction were compared with help of chi-square analysis to compute p-value.
Results: Out of 50 patients, 19(38.0%) were male while 31(62.0%) were females and mean age Group-O patients was 40.00±11.37 years and Group-C patients was 37.08±10.07 years. 17(68.0%) patients in Group-O had no pain 30 minutes after the application of greater occipital nerve block compared to 5(20.0%) patients who had no pain after multimodal analgesia while 8(32%) patients in Group-O had mild pain compared to 13(52.0%) patients in Group-C with p-value <0.001.
Conclusion: It is safe to conclude that greater occipital nerve block is a better alternative to pharmacological agents in treating and preventing chronic migraine.
