摘要
[目的]观察针刺辅助麻醉在膝关节镜手术七氟醚稳态吸入下对脑状态指数(cerebral state index,CSI)的影响。[方法]选取择期膝关节镜手术患者50例,采用随机数字表法分为针刺辅助麻醉组(A组)和对照组(B组)各25例。所有患者均七氟醚吸入诱导,气管插管后调整七氟醚呼气末浓度为1.0MAC并维持15min。A组患者实施针刺辅助麻醉,穴位选择阳陵泉、足三里。针刺后接G8605电针仪,正极接阳陵泉,负极接足三里,波形选用疏密波2/15Hz,选择电流强度8~12m A,刺激时间持续至术毕。记录静卧5min后(T1)、七氟醚达稳态(T2)、针刺辅助麻醉后20min(T3)、针刺辅助麻醉后30min(T4)各时间点的收缩压(SBP)、舒张压(DBP)、平均动脉压(MBP)、心率(HR)和CSI。[结果]A组患者T3~T4时的SBP、DBP、MBP、HR和CSI显著低于B组和T2时,差异均有统计学意义(P〈0.05)。[结论]针刺辅助麻醉能降低膝关节镜手术七氟醚稳态吸入下的CSI,同时产生降低血压和心率的作用,值得推广应用。
[Objective]To investigate the effect of acupuncture-assisted anesthesia on cerebral state index(CSI) under the steady-state anesthesia of sevoflurane. [Methods] Fifty patients scheduled for elective knee arthroscopy operation were randomly divided into two groups with 25 in each. All patients were induced with sevoflurane, the end-tidal concentrations of sevoflurane in two groups were adjusted to 1.0 MAC and maintained for 15 min after tracheal intubation, acupuncture-assisted anesthesia was used on the affected side in group A, Yanglingquan(GB34) and Zusanli(ST36) were selected as the acupoints. The positive and negative electrodes of the electropuncture apparatus(G8650) were respectively connected with Yanglingquan(GB34) and Zusanli(ST36). People reccived transcutaneous electrical acupoint stimulation with condensation-rarefaction wave(2/15 Hz, 8~12m A) untill the end of operation, patiant's body types SBP, SDP, MAP, HR and CSI were recorded at lying still for 5 min(T1), steady state of sevoflurane(T2), acupuncture-assisted anesthesia after 20 and 30 min(T3, T4). [Results] SBP, DBP, MBP, HR and CSI at T3~T4 were significantly lower in group A than those in group B and T2(P〈0.05). [Conclusion]Acupuncture-assisted anesthesia can reduce the CSI under the steady-state anesthesia of sevoflurane and lower blood pressure and heart rate at the same time.
