The effect of transcutaneous acupoints stimulation on enflurane anesthesil for craniotomy / 中华麻醉学杂志

ABSTRACT

The effect of transcutaneous stimulation to Hegu, Fengchi and Yuyao points with Han's Acupoint Nerve Stimulator on enflurane anesthsia and the hemodynamic changes during craniotomy were studied in 80 neurosurgical patients. The results showed that acupoint electric stimulation decreased the inhalating concentration and consumption of enflurane. The expired concentration of enflurane in HANS group was significantly lower than that in control group by a reduction of 37.8 % -47. 0%. The cardiovascular depression was lesser during operation, and the patients recovered faster and more stable after operation in HANS group. It was concluded that acupoint stimulation with HANS significantly potentiated the anesthetic effect and decraesed the side effect of enflurane.
