Abstract:
Objective To explore the two different anesthesia methods on hemodynamics and inflammatory cytokines in elderly patients during peroperative period.MethodsFifty elderly patients with Knee Replacement( ASA Ⅰ,Ⅱ )were randomly divided into general anesthesia group( group A,n =25 ) and combined general and epidural anesthesia group( group B,n =25 ).The changes of mean arterial pressure(MAP) and heart rate ( HR ) were monitored before induction of anesthesia ( T1 ),at intubation ( T2 ),during skin incision ( T3 ) and at the time of extubation ( T4 ),at 30 min after extubation ( T5 ).Blood samples were taken from artery for determination of plasma TNF-α,IL-6,IL-10 concentrations before tourniquet inflation ( T5 ),10 min after tourniquet deflation(T6),30 min after tourniquet deflation (T7)and 30 min after operation (T8)by enzymelinked immunosorbent assay(ELISA).ResultsThe MAP and HR of patients in two groups at T2,T3,T4 were all increased when compared with T1 [ group A:HR:( 94.3 ± 10.4 ) bpm,( 96.4 ± 12.7 ) bpm,(93.3 ± 11.1 )bpm vs(62.6 ±7.3)bpm;MAP:( 18.8 ±3.4)kPa,( 19.6 ±3.4)kPa,( 17.8 ±2.0)kPa vs ( 14.5 ± 1.5)kPa,P＜0.05;group B:HR(76.2 ±6.5)bpm,(70.1 ± 9.7) bpm,(71.5 ± 8.3) bpm vs(64.6 ± 8.4) bpm;MAP:( 16.3 ± 2.5 ) kPa,( 15.3 ± 1.2) kPa,( 14.8 ± 1.4) kPa vs ( 14.1 ± 1.3 ) kPa,P ＜ 0.05 ].There was significant difference on MAP and H R between group A and group B( F =11.957,9.745;P ＜ 0.05 ).The level of plasma TNF-α,IL-6 and IL-10 were significantly increased at T6 to T8 compared with T5 in both groups[ groupA:TNF-α:(4.36 ±0.18) ng/L,(7.54 ± 1.23) ng/L,(10.35 ±2.21 )ng/L vs (2.26 ±0.16) ng/L; groupA:IL-6:(4.32 ±0.21 ) ng/L,( 8.35 ± 1.26 ) ng/L,( 10.23 ± 2.23 ) ng/L vs ( 1.36 ± 0.08 ) ng/L; groupA:IL-10:(5.32±1.10) ng/L,(7.56 ± 1.36) ng/L,(8.63 ± 2.21) ng/L vs (1.25 ± 0.03) ng/L; groupB:TNF-α:(3.43 ±0.06)ng/L,(5.24 ±2.10) ng/L,(7.68 ± 1.43) ng/L vs(2.22 ±0.15) ng/L;groupB:IL-6:(3.41 ±0.08 ) ng/L,(5.34 ± 1.34 ) ng/L,( 8.54 ± 2.03 ) ng/L vs ( 1.28 ± 0.04 ) ng/L; groupB:IL-10:( 7.28 ± 1.22 )ng/L,( 10.53 ± 2.14)ng/L,( 12.45 ± 2.03 )ng/L vs( 1.31 ± 0.04)ng/L,P ＜ 0.05 ].And there was significant difference on TNF-α,IL-6 and IL-10 between group A and group B( F =7.889,3.554,5.443,respectively,P ＜0.05).ConclusionCompared with general anesthesia group,combined general and epidural anesthesia group can ensure hemodynamic stability of elderly patients during peroperative period very well and can reduce the releasing of inflammatory cytokins,it is a viable and an ideal method.
