ABSTRACT

The infiltration of solutions of lidocain with epinephrin are painful for the patient. Different methods have been studied to reduce pain like buffered solutions with sodium bicarbonate or the infiltration of warm solutions. Published reports include the analysis of pain in the face and extremities. We included a total of 100 patients with different pathologies from the Radiosurgical Unit of the National Institute of Neurology and Neurosurgery who required local anesthesia for the positioning of the stereotactic frame. We used three different solutions which were randomly administered in each patient. Pain score was measured with a analogue visual scale. We found a reduction of pain with the solution buffered to a pH of 6.512 in comparison with the lidocain with epinephrine with pH of 5.0. We may conclude that it is not necessary to raise the pH to 7.0 to achieve a reduction of pain.
