We have developed a new method of total intravenous anesthesia with droperidol, fentanyl and ketamine and have administered it to more than 400 surgical patients, ranging in ages from 4 to 80 years. Cardiac and neurosurgical patients were excluded. After establishing a routine monitoring, droperidol 0.06-0.1 ml.kg-1 was slowly given. ⋯ There are many anesthetic agents for total intravenous anesthesia. However, sufentanil, alfentanil and propofol are not available. Droperidol, fentanyl and ketamine are the best combination for this purpose in Japan so far.

A 58 year old man had been suffering from intractable left ophthalmic post herpetic neuralgia (PHN) for 7 years. He has also been treated for polyarteritis nodosa for 10 years. For pain relief, he was treated initially with frequent (4 times a day) stellate ganglion block (SGB) and peripheral ophthalmic nerve block for a month without relief. ⋯ Several days before the block, electric stimulation to control his pain was tested. Stimulation with the electricity (4.5 mA, 10 cycle and 400 microseconds) brought him complete relief from the pain during the stimulation. Trigeminal SEP showed no response to the stimulation of injured skin.

We investigated the cardiac output measured with a transtracheal doppler (TTD) tube in surgical patients and evaluated its usefulness during operations. This tube was located at the point where maximum velocity of blood flow was obtained in the ascending aorta. At this point the cross-sectional area of the ascending aorta was calculated and the cardiac output was obtained by multiplying this area with average blood flow velocity which had been ultrasonically determined. ⋯ O.: cardiac output. The direct correlation coefficient proved to be 0.85 at a risk factor of 0.01. The result suggests that this non-invasive TTD method is easily available and useful in monitoring the intraoperative cardiac output.
