0. 5mv. LAD occlusion was maintained for 50min and then released for reperfusion (120min) . Myocardial infarct size was measured by nitroblue tetrazolam at the end of experiment. Results There was no statistically significant difference in HR, MAP, cardiac output (CO), left ventricular systolic pressure (LVSP), left ventricular end-diastolic pressure ( LVEDP) and rate-pressure products ( RPP) among all groups during ischemia and early reperfusion period except for LVEDP in control group which was much higher than that in all preconditioning groups during the late reperfusion period. Compared with the control group, desflurane, sevoflurane, isoflurane and G+ desflurane reduced myocardial infarct size by 41%, 47%,31.7% and 17.8% respectively without significant homodynamic effects. Myocardial infarct size in G + desflurane groups was significantly larger than that in desflurane group. Conclusion Preconditioning with desflurane, sevoflurane and isoflurane reduce myocardial infarct size in rabbits to some extent. The protective effects may be partly medialed via activation of KATP channel.

To assess the concentration-responses relationships of propofol, 16 adult patient,ASA grade Ⅰ-Ⅱ,scheduled for upper abdominal operation, were randomly allocated to undergoing epidural block (group Ⅰ, n = 8)or combined anesthesia (group Ⅱ, n = 8) respectively. After a bolus injection of propofol 2.5mg ?kg, blood pressure (BP), heart rate (HR) and tidal volume (TV) were recorded, and drowsiness,amnesia,cooperation and orientation were evaluated by scorring scales in both groups. The venous samples were taken before and after the administration to measure the propofol plasma concentration by spectrofluorophotometric detector. The results revealed that there were no significant differences in pharmacokinetic parameters between two groups;the plasma concentration of propofol at 2. 5rag. L~(-1) was required for adequate anesthesia,and 1.5 to 1.9rag. L~(-1) for hypnosis,the patients were fully awake at 0.94?0.3mg. L~(-1); BP,HR and TV were significantly depressed at more than 2.0rag. L~(-1), and recovered to baseline at less than 1.5mg. L~(-1). It is suggested that there are good relationships between propofol plasma concentrations and its pharmacodynamic responses.

Objective: To compare cumulative dose technique with single dose technique for determining dose-re sponse relationship of rocuronium during balanced anesthesia. Method: Thirty-four ASA grade Ⅰ-Ⅱ patients, aged 23- 65 years, undergoing elective surgery,were randomly allocated to single dose group(n=24) or cumulative dose group (n=10). Single dose group was further divided into 4 subgroups receiving 150,200,250 or 300?g/kg of rocuronium re spectively. In cumulative dose group, the initial dose of 150 or 200 ?g/kg rocuronium was followed by a second dose de termined individually to produce about 90% neuromuscular block. The ulnar nerve was stimulated at the wrist to mea sure the accelography of thumb adduction. The relationship between probit-transformed depression of first twitch height of TOF and the logarithm dose of rocuronium was analysed using linear regression. Result: ED_50 and ED_95 of rocuronium were 193.6?69.1 and 367.2?72. 7?g/kg respectively in single dose group, and 213.0?55.1 and 418.5? 61.7?g/kg respectively in cumulative dose group. No statistically significant differences were found in the slope,inter cept,ED_50 and ED_95 values between two groups. Conclusion: The two-dose cumulative technique can be used as effec tively as traditional single dose technique in determining the dose-response relationship of rocuronium.
