Comparison of greater occipital nerve and supra orbital nerve blocks methods in the treatment of acute migraine attack: A randomized double-blind controlled trial
Abstract
OBJECTIVE
The main goal of this investigation is to compare the Greater Occipital Nerve (GON) and Supra Orbital Nerve (SON) block methods used in the treatment of migraine attacks in the ED with each other, in combination, and with a placebo.
METHODS
This study was planned as a single center, prospective, double-blind, randomized control study. The patients were divided into 4 groups: GON, SON, Combined, and Placebo. Groups were named according to the nerve areas that were blocked. Therefore1% lidocaine for nerve blockade and 0.9% NaCl for placebo effect was used. Along with the time of admission, baseline pain scale values, as well as recordings at 30 and 60 min in addition to the Visual Analog Scale (VAS) at the 120th min. and Likert-Type (LT) Verbal scale at the 120th min. were measured. The primary outcome of this study was a change in the VAS and LT values at the 0-120th minute after treatment RESULTS: In this study, 128 patients in 4 groups were included in the analysis. In the GON group, SON group, and Combined group, the change observed at the 120th minute scores compared to baseline VAS scores was higher than Placebo group [OR (95% CI) = -17.4 (-24.8, -9.9), 32.1 (23.8, 40.3), 49.5 (41.9, 57), respectively]. In inter-group comparison, it was found that the VAS and LT scores of the Combined group and the GON group improved at a higher rate than the SON group CONCLUSIONS: SON blockade, GON blockade, and a combination of these two blockades are effective treatment…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 128 participants or records.
