One of the annoying side effects of spinal anesthesia in cesarean section surgery is the post-dural puncture headache (PDPH) which occurs 2 to 5 days after the surgery. The aim of this study was to examine the effect of bilateral occipital nerve block (GONB) in the treatment of PDPH after cesarean section surgery. In this randomized clinical trial, 74 pregnant women who underwent cesarean section with spinal anesthesia in 2017 and referred to Rafsanjan Pain Clinic with PDPH, were randomly assigned into two groups of 37. In the first group, GONB treatment was done by bupivacaine and dexamethasone and the second group received oral drug treatment with acetaminophen and pregabalin. Patients in either group were evaluated for headache severity before intervention, 1, 6 and 24 hours after intervention. Data was analyzed using two-way repeated measures ANOVA. The results of the statistical test showed that the interaction effect of the type of treatment and the time of the evaluation of the headache was statistically significant (F=130.912, p<0.001). This means that the rate of headache reduction during the study period was significantly higher in the GONB group than in the oral treatment ones. According to the results, despite the effectiveness of both therapies, the effect of GONB on reducing headache severity was greater than that of medication. It seems that GONB can be used as an effective alternative to PDPH treatment.

Medication overuse headaches (MOH) include headaches that last more than 15 days a month and usually occur after long-term use of analgesic. Most methods of medical treatment are ineffective. In some studies, great occipital nerve block is used to treat the headaches. This double-blind experimental study was performed in adult patients with MOH who attended Sina Hospital in Tehran from June 2009 to June 2011. Greater occipital nerve (GON) block was done in the two groups of patients by administering a combination of 3 ml of 0.5% bupivacaine and 2 ml of 5% saline or 3 ml of 0.5% bupivacaine and 80 mg of methyl prednisolone. We evaluated headache severity by Visual analog scale (VAS) and recorded days without headache. If patients were taking pain medications, preventive medications were given as usual before and after the injection. Student's t-test was performed for statistical analysis and a P<0.05 was considered significant. Overall, 13 male and 19 female patients with a mean age of 39.88±8.76 years participated in the study. The mean reduction in headache severity one hour after injection was 5.56±1.03 and 4.63±1.92 in the first and second groups, respectively. Average days without headache one month after injection were 8.75 and 4.75 days in the first and second groups, respectively. There were no significant differences between the two groups. Both methods seem to be effective in medication overuse headaches treatment. This finding is important as non-responders to conventional methods will otherwise have a decreased quality of life.
