title: [The on-line simulation of blood propofol concentration by personal computer transmitting settings of the syringe pump via a digital port].
abstract: A program for on-line simulation of blood propofol concentration was developed. Various pharmacokinetic model programs are available for the estimation of intravenous anesthetic concentration. But manual entry of data such as body weight, rate of infusion and the timing of changing the flow rate is mandatory in these programs. This limited the use of these programs for investigational use only. In a new program, the data required such as total dose, flow rate, body weight and time were collected automatically on-line via the digital outlet of the syringe driven pump (Terumo STC525X, Japan and Graseby 3500, UK) to a personal computer (Apple Macintosh Power Book Duo230 or Power Book 520, USA). Based on the obtained data, pharmacokinetic model was solved with personal computer. Calculated blood concentrations of propofol were displayed in a numeric form and a trend graph was obtained. This program provides useful information for maintainance of anesthesia with propofol.
