The transtracheal method of local anesthesia has been reviewed and 437 cases who had bronchologic examination have been discussed.
The technic described permits controlled administration of a predetermined amount of the anesthetic agent in a single injection as quickly and as safely as the regional infiltration of anesthetics. The drug mostly used was cocaine hydrochloride, 5 per cent solution, and the average effective dose required was 198 mg in 91 per cent of the cases.
Triflupromazine given intravenously immediately before the transtracheal injection of the anesthetic, ordinarily at a dose of 10 mg prolongs the local effect of cocaine, and proves to be a good substitute for barbiturates and opiates to sedate the patient.
The whole procedure usually takes about two minutes.
