Induction of anesthesia always is the most important problem for the anesthetist, because during this period the patent is susceptible to dangers and complications. Furthermore, the cardiovascular state during this period is so unstable that any stimulation, either due to anesthetic or surgical procedures, inadequately added, will deteriorate it; the tracheal intubation or even insertion of the laryngescope into the mouth, will often cause remarkable circulatary responses during this period. The responses, notably the pressor response, could be followed by a mishap particularly in the aged or hypertensive patients, and poor risk patients with cardiovascular dysfunction. Although the circulatory responses to tracheal intubation have been observed by many investigators and variously interpreted almost no report is available on the problem of prevention or inhibition of the responses. Therefore, we have used five percent solution of Carbocain in an attempt to anesthetize the laryngeal, and the pharyngeal areas and the base of the tongue with spray prior to tracheal intubation and discussed its inhibitory effect on the pressor reflex mechanism mediated over the sympatheticus which is innervated in these areas.
