Keywords
acupoint stimulation, general anesthesia, sleep, elderly patients
Brief summary
Sleeping model can be affected after surgery. Anesthetics may be involved in the change. The changing of sleeping mode may exert adverse effect on postoperative recovery. Acupuncture and related techniques has been used for treating sleeping disorder. In this study, the effect of transcutaneous electrical acupoint stimulation on sleeping model after general anesthesia will be observed.
Interventions
OTHERtranscutaneous electrical stimulation
electrical stimulation is given through electrodes attached to the skin
electrodes are attached to the skin area of Neiguan acupoint, which is located on 3cm above the transverse crease of the wrist
