Abstract:
Objective To observe the effect of transcutanous acupoint electrical stimulation(TAES)and dexmedetomidine on postoperative cogni?tive dysfunction in female patients underwent laparoscopic surgery. Methods Nighty patients scheduled for laparoscopic surgery were recruited in this study and randomly divided into control group(group C,n=30),TAES group(group T,n=30)and dexmedetomidine group(group D,n=30). In group T,patients received TAES treatment 30 min before the anesthesia until the end of the surgery at Neiguan(PC 6)and Zusanli(ST 36). The frequency was 2/100 Hz. In group D,patients were intravenously administrated with dexmedetomidine(0.5μg/kg)before the induction. All the patients were given routine general anesthesia. Drugs induced were sulfentanyl,etomidate and cisatracurium. Sevoflurane was given to main?tain the bispectral index(BIS)between 40 and 55. The time of extubation and in PACU was recorded. The serum S100βlevel was assessed at pre?operation(T0),the end of operation(T1)and 24 h after operation(T2). Mini?mental state examination(MMSE)was adopted to evaluate and re?cord the changes in cognitive function 1 day before operation and 24 h after operation. Results The incidence rate of POCD in group T and group D were lower than that in group C(all P<0.05). The level of S100βin group T and group D was lower than those in group C at T1 and T2 separately (all P<0.05). The time of extubation and time in PACU in group D were longer than those in group C and group T(all P<0.05),and the incidence of bradycadia in group D was higher than that in the other groups(all P<0.05). Conclusion TAES and dexmedetomidine reduce the incidence of cognitive dysfunction,decrease the release of S100βprotein. However,dexmedetomidine increases bradycadia,and prolongs extubation time and stay time in PACU. Hence,TAES deserve to be recommended practically.
