Electroacupuncture for Preventing Postoperative Delirium in Older Adults Undergoing Total Knee Arthroplasty
Sponsor: Fujian Provincial Hospital
Summary
Electroacupuncture may improve cognitive function and altered consciousness, but its effect on postoperative delirium in older arthroplasty patients remains unexplored. This study aims to assess the efficacy of electroacupuncture in preventing postoperative delirium in older adults undergoing total knee arthroplasty.

Interventions
Disposable acupuncture needles (0.30 × 75 mm)
Disposable acupuncture needles (0.30 × 75 mm), placebo needles (0.30 × 25 mm) and SDZ-V electroacupuncture devices (Hwato, Suzhou Medical Supplies Factory Co Ltd, China) will be used. Electrodes attached to the needle handles will deliver stimulation for 30 minutes (2 Hz/15 Hz frequency, 1 mA intensity) to cause mild skin movement without pain.
Placebo needles (0.30 × 25 mm)
Disposable acupuncture needles (0.30 × 75 mm), placebo needles (0.30 × 25 mm) and SDZ-V electroacupuncture devices (Hwato, Suzhou Medical Supplies Factory Co Ltd, China) will be used. Sham electroacupuncture will use blunt-tipped placebo needles without current output, which retract into their handles to simulate skin insertion.
SDZ-V electroacupuncture devices
Disposable acupuncture needles (0.30 × 75 mm), placebo needles (0.30 × 25 mm) and SDZ-V electroacupuncture devices (Hwato, Suzhou Medical Supplies Factory Co Ltd, China) will be used. Electrodes attached to the needle handles will deliver stimulation for 30 minutes (2 Hz/15 Hz frequency, 1 mA intensity) to cause mild skin movement without pain.
