Abstract:
Objective To investigate the effect of combined general anesthesia with localanesthetic infiltration on heart rate variability and hemodynamics in laparoscopic cholecystectomy.Methods By simple randomization 70 patients undergoing laparoscopic cholecystectomy were assignedto two groups,68 patients completed the study(34 in each group).Group GA was given generalanesthesia.Group GL was given general anesthesia combined with local anesthetic.Iow-frectuency(LF),high-frequency(HF),LF/HF,Lfnu(LF/TP×100%),Hfnu(HF/TP×100%)and totalpower(TP),were recorded at the time points of baseline(T_0),skin incision(T_1),skin closure(T_2)and 1 h(T_3),3 h(T_4)after surgery.MAP and HR were recorded at the points of baseline,skinincision,skin closure and 1,3 h after surgery.Results Compared with the baseline,there was anincrease in MAP and HR at T_1,T_3,T_4(P<0.05)in group GA. Heart rate variability changesshowed that in group GA Lfnu,LF/HF increased significantly at T_1-T_4(P<0.05)and in group GLLF/HF increased significantly at T_1,T_2(P<0.05),and TP in group GA and group GL decreasedsignificantly at T_1,T_2(P<0.05).Conclusion Our results support that combined general anesthesiawith local anesthetic infiltration has lass influence on hemodynamics and automomic nerve,and can bean useful analgesic adjuvanct for patients undergoing laparoscopic cholecystectomy.
