Objective: To observes the effects of different dosage of Sufentanill in induced general anesthesia period on the hemodynamics and the blood plasma catecholamine in hypertension of geraticsMethods: Eighty ASAâ… orâ…¡hypertension geratics, age 65-75 years old, were randomized into four groups( n=20each), groupâ… (fentanil 3ug/kg), groupâ…¡(sufentanil: 0.2ug/kg), groupâ…¢(sufentanil: 0.4ug/kg), groupâ…£(sufentanil: 0.6ug/kg), Separately records four group of patients to record SBP, DBP, MAP, HR before the induction T0, before the intubation T1, inserts a tube 1min T2,3min T3,5min T4, and records the above time extraction venous blood, unites the immunity adsorption law with the enzyme to measure the blood plasma catecholamine density the change.Results:â‘ In T1 time, the groupâ…¢is lower than the basic value on SBP, DBP, MAP, but the decline rate is small and has statistics significance with other each group of differences, (P<0.05) In T2 time, the groupâ…¢onDBP, MAP restores to the baseline, but the groupâ… andgroupâ…¡already surpassed the foundation value onDBP, MAP in this time interval, The groupâ…£still obviously was lower than the baseline, and has statistics significance with other each group of differences, (P<0.05) In T3 time,the SBP of groupâ…¢approaches in the basic value, The groupâ… andâ…¡is higher than the baseline, The groupâ…£still obviously was lower than the baseline (P<0.05) But each group of DBP, MAP in this time difference non-statistics significance. In the T4 time, groupâ…£SBP still obviously was lower than outside the baseline (P<0.05),Other each group of three targets approach in the baseline, and difference non-statistics significance.â‘¡. In T1 time, HR of groupâ…£obviously is lower than outside the baseline, other each group and the baseline does not have the difference, but in T2~ T4 time interval, The groupâ… andâ…¡are higher than the baseline, The groupâ…£in the time T2, T3 still obviously was lower than the baseline, restores in the T4 point in time to the basic value level. But the groupâ…¢time interval and the foundation value does not have the difference in T2~ T4.â‘¢Blood plasma NE difference non-statistics significance, groupâ… when T4 the E density slightly has elevates(P<0.05) When T4 the groupâ…¢blood plasma E density is lower than F group (P<0.05) , four group of patient various points in time blood plasma NE density difference non-statistics significance.â‘£The Fentanyl group patients realize the evanishment time ratio to extend Leader Fentanyl each (P<0.05)⑤Encircles the intubation time groupâ…¡andgroupâ… has hypertension and the tachycardia the formation rate is higher than obviouslyâ…¢Withgroupâ…£, The groupâ…£hypotension's formation rate is higher than obviouslyâ…¡Withgroupâ…¢. blood plasma catecha phenol amine: With T0 when compares, four group of patient various points in timeConclusion: sufentanil 0.4ug/kg in the general anesthesia intubation period stress to respond that is small. And compares with 0.2ug/kg and 0.6ug/kg, 0.4ug/kg has the stabler blood stream dynamics . |
