Effects of Intravenous Anesthesia using Propofol TCI (Target Controlled Infusion) System in Plastic Surgery under Local Anesthesia

ABSTRACT

Nowadays in the field of plastic surgery, operations with no general anesthesia have been much increased, using daily surgery center. We used "Propofol TCI system" to control exact target concentration of conscious sedation and to reduce any systemic complication of the other local anesthetics. Twenty of ASA Class I or II patients were scheduled for elective surgery using Diprifusor(R) TCI system at 0.8-1.9 ug/ml target concentration. We estimated the proper target concentration, time of awakening, postoperative patient satisfaction and presence of postoperative amnesia. All the patients was satisfied except one patients who underwent nasal tip plasty. The target concentration of the conscious sedation varies with age and the type of operation but average concentration was 1.4-1.6 ug/ml. The average time of awakening, which we estimated by the time of eye opening was 2.6 minutes. Postoperative systemic complication and unusual vital sign were not present. We present here our satisfactory results using propofol infused by TCI(Target controlled infusion) system. This system is called 'Diprifusor(R)' and has a benefit of excellent sedative effect, low complication rate, safety, and rapid awakening time which enables the patient to return to his normal life cycle.
