[The efficacy of therapeutic nerve blocks in patients with cervicogenic headache].

Abstract

AIM:

To compare the efficacy of 2% articaine solution and 2% lidocaine solution used to perform therapeutic nerve blocks of the large occipital nerve in patients with cervicogenic headache.

MATERIAL AND METHODS:

A randomized prospective comparative clinical study was conducted in two groups treated with articaine (n=22) or lidocaine (n=21). The therapeutic great occipital nerve blocks were performed on the 1st, 3d and 5th days of treatment. The efficacy of treatment was assessed by the pain intensity measured with the Visual Analogue scale (VAS) and the duration of individual pain paroxysms on the 5th and 10th days.

RESULTS:

The baseline VAS pain intensity was 6.3±1.2 and 5.9±2.0 centimeters, whereas the duration of individual pain paroxysms was 7.8±2.3 and 9.1±2.8 hours in the articaine group and the lidocaine group, respectively. By the 5th day, there was a more dramatically decrease in VAS pain intensity and duration in the articaine group (up to 3.0±0.8 and 4.3±1.2 centimeters VAS (p<0.05)) compared to the lidocaine group (up to 1.9±0.6 to 4.8±1.3 hours (p<0.05)). By the 10th day, the pain intensity did not differ between groups (1.2±0.5 and 1.7±0.7 centimeters (p>0.05)). The duration of pain episodes was still lower in the articaine group (0.5±0.08 hours) compared to the lidocaine group (2.4±0.8 hours) (p<0.05).

CONCLUSION:

Therapeutic large occipital nerve blocks with 2% solution of articaine show the significant decrease in pain intensity and duration of pain paroxysms in a short period of time for patients with cervicogenic headache.
