Magnetic Brain Stimulation Trial Aims to Curb Postoperative Delirium in Elderly Patients

A new clinical trial is testing whether magnetic brain stimulation can prevent postoperative delirium in elderly patients undergoing joint replacement surgery. The study, led by Zhao Zj., Yang Y., Wei Sr., and colleagues, aims to reduce a common complication that extends hospital stays and raises healthcare costs.

Postoperative delirium frequently affects older adults after arthroplasty, often leading to longer recovery times and greater burdens on families and medical systems. Researchers are now exploring repetitive transcranial magnetic stimulation (rTMS) as a non-invasive way to stabilise brain function during the critical period following surgery.

The trial, a single-centre, randomised controlled investigation, will enrol elderly patients scheduled for joint replacement. Participants will receive either active rTMS treatment or a sham procedure for comparison. The magnetic pulses will target the dorsolateral prefrontal cortex, an area linked to attention and decision-making. Safety remains a priority, with the team closely monitoring potential side effects such as headaches or scalp discomfort. They also recognise that delirium’s complex causes may require broader perioperative strategies, including better anaesthesia management, pain control, and early mobility. The study’s full protocol has been published in *BMC Geriatrics* to encourage transparency and invite feedback on the methodology.

If successful, the trial could lead to fewer cases of postoperative delirium in elderly arthroplasty patients. This might improve recovery outcomes, ease pressure on caregivers, and lower healthcare expenses. The findings will help determine whether rTMS should become part of standard perioperative care.
