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.

Conditions

  • Postoperative Delirium

Interventions

DEVICE

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.

DEVICE

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.

DEVICE

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.
