From a patients instruction sheet about the use of nasally applied local anesthetic to abort CH attacks:
Quote:… I should lie on my back on a flat surface extending my neck towards the floor at a 30-45° angle from the horizontal. I should then turn my head towards the headache side – that is, to the right side in the event of right sided headache or towards the left side in the event of a left sided headache. I will then apply 1/2 to 1/3 dropperful increments of the solution in a direction towards my headache side eye and sniff through my nose in an inward direction at the same time. I will remain in this lying position for at least 30 seconds before arising. In the event of failure of the first application to subdue my headache I will apply it once more in a similar manner.

The red spot in this illustration shows the area, to which the lidocaine solution should be applied.
Barré was the first to use the local anesthetic cocaine as an abortive. Later studies using the same procedure of application found that lidocaine
nasal drops (not spray) are equally effective, when applied correctly according to the instruction described above.
Quote:In his evaluation of intranasal lidocaine in the treatment of cluster headache (Headache 1995;35:83-84), Robbins found that none of his 30 patients had achieved excellent results and only 27% achieved moderate benefit. He concluded that intranasal lidocaine was only marginally helpful therapy for cluster headache.
These findings are considerably poorer than those of Kittrelle et al,1 who had reported a complete response in 4 of 5 patients, or Hardebo and Elner2 having reported a 50% or greater response in 40% of patients. It should be important to note, therefore, that the lidocaine preparation used by Robbins (spray) differed from that used in the other studies (lidocaine nose drops). It would have been more prudent for Robbins to have concluded that in view of earlier treatment results with lidocaine nose drops, lidocaine nasal spray appeared to be less beneficial in the symptomatic treatment of cluster headache.
More importantly, it is now common experience that, in at least some patients, intranasal lidocaine affords rapid and total relief of cluster attacks. This demonstrates the significance of the facial nerve's sphenopalatine ganglion and periganglia in the pathogenesis of cluster attacks.
