1 000 rnl were randomly divided into 2 groups : AHHD group ( n = 18) and control group ( n = 18). The patients were premedicated with intramuscular atropine 0.007-0.01 mg?kg-1 . Radial artery and right internal jugular vein were cannulated before induction of anesthesia for MAP and CVP monitoring, blood sampling and fluid administration. Anesthesia was induced with TCI of propofol. The target plasma propofol concentration was set at 3 ?g ? ml -1 . When the patients lost consciousness, fentanyl 2 ?g ? kg-1 was given intravenous and tracheal intubation was facilitated by vecuronium 0.1 mg? kg-1 , 10min after intubation additional fentanyl 2 ?g? kg-1 and vecuronium 0.08 mg? kg-1 were given. In AHHD group lactated Ringer's solution 10 ml ? kg-1 was infused over 30 min before TCI propofol was started. 10 min after start of TCI propofol 6% HES 20 ml? kg-1 was infused within 30 min. In control group the patients received only lactated Ringer's solution 10 ml?kg-1 . TCI of propofol was maintained for 1 h. Arterial blood samples were taken before and 2, 5, 10, 20, 30, 40, 50 and 60 min after TCI propofol was started, and at 2.5, 5, 10, 15, 20, 25, 30 min after termination of TCI propofol for determination of blood concentration of propofol by gas-chromatography - mass spectrometry (GC-MS) . The TCI system comprising Graseby 3 500 infusion pump controlled by Stelpump 1.07 software which included Tackley pharmacokinetic parameters. Results In AHHD group Hb was reduced from initial (130? 14)g?L-1 to (90? 15)g?L-1 and Hct from initial 38% ? 3% to 26% ? 4 % at the end of AHHD. The measured blood propofol concentrations were significantly lower in AHHD group than those in control group at the corresponding time points (P

Obuective To assess the population pharmacokinetic parameters and analyze thecharacteristics of pharmacokinetics of propofol given by target-controlled infusion (TCI) in Chinese using anoulinear mixed effect model (NONMEM) program. Methods Sixty-one ASA Ⅰ-Ⅱ patients (26 male, 35female) aged 18-64yr, weighing 41-83kg undergoing elective operation under general anesthesia were studied. TheTCI system consisted of (1 ) Stel pump Software 1 .07 designed by Coetzee, (2) cable R232 connector, (3)Graseby 3500 infusion pump, (4 ) pharmacokinetic parameters developed by Tackley. The patients werepremedicated with intramuscular phenobarbital sodium 1-2 mg?kg~(-1) and atropine 0. 5 mg. Anesthesia was inducedwith TCI of propofol. Target plasma concentration of propofol was set at 3?g?ml~(-1). Fentanyl 2?g?kg~(-1) andvecuronium 0. 1mg?kg~(-1) were given i. v. when the patients lost consciousness. TCI of propofol lasted 60 min. 976blood samples were obtained before induction of anesthesia and at 2, 5, 10, 20, 30, 40, 50, 60, 62. 5, 65, 70,75, 80, 85, 90 min ther TCI was started for determination of plasma propofol concentration by gas-chromatography-mass spectrometry (GC-MS). Population pharmacokinetic parameters were assessed and thecharacteristics of the pharmacokinetic profile was analyzed using NONMEM program. Results The pharmacokineticprofile of propofol given by TCI in Chinese was best described by an open two-compartment model. Thepharmacokinetic parameters for the final model: K_(10) was 0.111, K_(12) 0 .064 and K_(21) 0 .023 min~(-1); V_1 was 0 .205and V_2 0.404 L?kg~(-1); CL_1 was 22 .76 and CL_2 13 .24 ml?min~(-1). The estimated concentrations were well correlatedwith the measured concentrations in the final model. Weight was found to covariate significandy with V_1 and CL_1and age with K_(21). However gender had no significant effect on pharmacokinetic parameters.Conclusion Thepopulation pharmacokinetic profile of propofol administered by TCI in Chinese can be well described by an open two-compartment model. The volume of central compartment was smaller and the inter-compartmental transfer ratefrom central compartment to peripheral compartment was faster in Chinese.

Objective To investigate the effect of acute hypervolemic hemodilution (AHHD) on pharmacokinetics of propofol given by target-controlled infusion (TCI). Methods Thirty-six ASA Ⅰ-Ⅱpatients (18 male, 18 female) undergoing elective surgery were randomized to one of two groups: control group (n = 18) and AHHD group ( n = 18). The patients were premedicated with atropine 0.007-0.01mg?kg-1 and phenobarbital 1-2mg?kg-1 i.m. . Radial artery and right internal jugular vein were cannulated before induction of anesthesia. Anesthesia was induced with TCI of propofol. The target plasma propofol concentration was set at 3 ?g?ml-1. When the patients lost consciousness, fentanyl 2?g? kg-1 was given i.v. and tracheal intubation was facilitated by vecuronium 0. 1 mg?kg-1 . Ten minutes after tracheal intubation an additional dose of fentanyl 2 ?g?kg-1 and vecuronium 0.08 mg?kg-1 was given i.v.. TCI of propofol continued for 1 hour. In AHHD group lactated Ringer's solution 10 ml?kg-1 was infused over 30 min before induction of anesthesia. 10 min after TCI propofol was started, 6 % HES 20 ml ?kg-1 was infused within 30 min. In control group the patients received only lactated Ringer's solution 10 ml? kg-1 . All fluid infused was prewarmed to 35℃ Arterial blood samples were taken before and 2,5, 10, 20, 30, 40, 50 and 60 min after TCI propofol was started and 2.5, 5, 10, 15, 20, 30 min after termination of TCI propofol for determination of blood concentration of propofol by gas-chromatography-mass spectrometry (GC-MS) . The TCI system consisted of Graseby 3500 infusion pump controlled by Stelpump 1.07 software, which included Tackley pharmacokinetic parameters. Results The demographic data including sex, age, body weight and amount of propofol consumed were comparable between the two groups. The pharmacokinetic profile of propofol given by TCI was best described by a two-compartment open model during AHHD. The pharmacokinetic parameters tor the final model; K10 was0.116, K12 0.0907 and K210.024mm-1 ; V, was 0.311 and V2 0.446L?kg-1 ; Cl1 was 33.31 and Cl2 16.65 ml?min-1?kg-1 respectively. V1 and V2 were significandy larger, and transfer and clearance rates were significantly higher in AHHD group than those in control group. At the end of AHHD, Hb decreased by 31.0% and Hct by 31.3%; total plasma protein decreased by 30.1% and plasma albumin by 25.7% as compared with the baseline values before AHHD. Conclusion AHHD has significant effect on pharmacokinetics of propofol. Less propofol is bound to plasma protein and duration of action is relatively shorter. During AHHD the target plasma propofol concentration should be increased to some extent to achieve the same depth of anesthesia.
