[Intravenous anesthesia using continuous administration of propofol and fentanyl: fentanyl administration procedure and quality of awareness].
BACKGROUND
We studied total intravenous anesthesia using continuous administration of propofol and fentanyl and examined especially the method of fetanyl administration.


METHODS
Anesthesia was induced with fentanyl 2 micrograms.kg-1 and propofol 2 mg.kg-1. Fentanyl 1 microgram.kg-1 was then administered before the start of the operation and infused continuously at a rate of 0.02 microgram.kg-1.min-1 during operation. Propofol was also infused continuously at 4-10 mg.kg-1.min-1.


RESULTS
These methods allowed a significant reduction in the necessary dose of fentanyl and propofol compared with ordinary methods, and a stable general condition was maintained during the operation. Additionally, high quality of awareness was obtained after the recovery.


CONCLUSIONS
This continuous administration procedure of fentanyl reduced the total doses of both propofol and fentanyl, allowing high quality of awareness after the recovery.
