目的:观察术中失血对丙泊酚靶控输注(TCI)时血浆药物浓度(cm)及听觉诱发电位指数(AAI)的影响。方法选择美国麻醉医师协会(ASA)Ⅰ~Ⅱ,拟行择期骨科脊柱手术的患者108例,按术中失血量分为3组。 A组:失血量≤300 mL,B组:300 mL<失血量≤600 mL,C组:失血量>600 mL。3组麻醉诱导和维持均使用丙泊酚靶控输注,同时进行听觉诱发电位麻醉深度监测。在丙泊酚麻醉开始后5(T1),30(T2),60(T3),120(T4),180(T5),240 min(T6)测定丙泊酚血药浓度(cm),并记录血液动力学变化和AAI,评价丙泊酚靶控输注的性能。结果 T4-T6时点C组失血量明显大于A、B组(P<0.01),B组大于A组( P<0.05);补液量C组明显高于A、B组( P<0.01),B组高于A组( P<0.05)。C组较A、B组平均动脉压(MAP)在T5、T6时点明显降低(P<0.05)。3组T3、T4血药浓度较T1明显下降( P<0.05),T5、T6较T1下降更显著( P<0.01);C组T4、T5、T6血药浓度较A组明显下降( P<0.05)。 C组T6时丙泊酚靶控系统偏离度为-17.74%。结论丙泊酚靶控输注时失血会引起实际血药浓度明显低于设定的靶浓度,根据AAI监测实时调整靶浓度是维持麻平稳和血液动力学稳定的重要方法。
目的:觀察術中失血對丙泊酚靶控輸註(TCI)時血漿藥物濃度(cm)及聽覺誘髮電位指數(AAI)的影響。方法選擇美國痳醉醫師協會(ASA)Ⅰ~Ⅱ,擬行擇期骨科脊柱手術的患者108例,按術中失血量分為3組。 A組:失血量≤300 mL,B組:300 mL<失血量≤600 mL,C組:失血量>600 mL。3組痳醉誘導和維持均使用丙泊酚靶控輸註,同時進行聽覺誘髮電位痳醉深度鑑測。在丙泊酚痳醉開始後5(T1),30(T2),60(T3),120(T4),180(T5),240 min(T6)測定丙泊酚血藥濃度(cm),併記錄血液動力學變化和AAI,評價丙泊酚靶控輸註的性能。結果 T4-T6時點C組失血量明顯大于A、B組(P<0.01),B組大于A組( P<0.05);補液量C組明顯高于A、B組( P<0.01),B組高于A組( P<0.05)。C組較A、B組平均動脈壓(MAP)在T5、T6時點明顯降低(P<0.05)。3組T3、T4血藥濃度較T1明顯下降( P<0.05),T5、T6較T1下降更顯著( P<0.01);C組T4、T5、T6血藥濃度較A組明顯下降( P<0.05)。 C組T6時丙泊酚靶控繫統偏離度為-17.74%。結論丙泊酚靶控輸註時失血會引起實際血藥濃度明顯低于設定的靶濃度,根據AAI鑑測實時調整靶濃度是維持痳平穩和血液動力學穩定的重要方法。

Objective To investigate the effect of blood loss on plasma concentration and auditory evoked potential index ( AAI) of propofol tar-get controlled infusion.Methods One hundred and eight patients ( ASA gradeⅠorⅡ) who were given surgical operation were randomly divided into three groups: group A, blood loss≤300 mL; group B,300 mL <blood loss≤600 mL;group C, blood loss>600 mL.In three groups, in-duction and maintenance of anesthesia were performed by propofol target controlled infusion , simultaneous auditory evoked potential monitoring the depth of anesthesia .Arterial blood samples were taken at anesthetize 5 (T1),30(T2),60(T3),120(T4),180(T5),240 min(T6), and at the same time, the changes of hemodynamics and auditory evoked potential index ( AAI ) were recorded for evaluating the performances of TCI sys-tems.Results In the duration of T4 -T6 , the blood loss in group C was significantly higher than group A and B ( P<0.01 ) , group B higher than group A(P<0.05);and the volume of fluid infusion of group C was sig-nificantly higher than group A and B ( P<0.01 ) , group B higher than group A(P<0.05).The MAP of group C decreased more than group A and group B (P<0.05) in the duration of T5 -T6.The plasma concentration of T3 and T4 were lower than T1 (P <0.05);T5 and T6 significant decreased than T1 ( P<0.01 ) , group C was lower than group A ( P<0.05 ) in the duration of T 4 -T6 .The MDPE was 17.74%of group C in T6 .Conclusion Blood loss can cause the actual plasma concentration of propofol below than target concentra-tion.According to AAI monitoring to regulate target propofol concentration can maintain stable vital signs .
