Clinical Trial Summary

To determine whether continuous theta burst stimulation can cure postoperative delirium in senior patients.

Description:

Postoperative delirium(POD), a syndrome characterized by an acute change in attention, awareness and cognition, is one of the most common postoperative complications among elderly patients. Impaired neuronal network connectivity is likely one of the several neurobiological processes that contribute to POD pathogenesis. Recently, continuous theta burst stimulation (cTBS) was demonstrated to improve cognitive function in patients with mild cognitive impairment.Recent research suggests that cTBS has positive effect on improving the connectivity and reorganization of the brain network. Therefore, we plan to conduct an exploratory study in participants undergoing elective surgeries to determine whether cTBS can cure POD in this senior patient population.

Intervention

Device:
• Continuous theta burst stimulation (cTBS)
Patients assessed for postoperative delirium will be treated by consist of 600 pulses per session, delivered over the right dorsolateral prefrontal cortex at 80% of resting motor threshold (RMT). Every session cTBS consists of 50 Hz triplets of pulses delivered at 5 Hz for 40 seconds for a total of 600 pulses. Every set simulation includes 3 sessions.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Cure rate of POD after a single cTBS treatment	No POD was evaluated by CAM at 1 hour after a single cTBS treatment on the day of the first occurrence of POD and at any time point thereafter.	7 days after surgery
Secondary	Cure rate of POD after multiple cTBS treatments	No POD was evaluated by CAM at 1 hour after two or three cTBS treatments and at any time point thereafter.	7 days after surgery
Secondary	Severity of postoperative delirium changed after each cTBS treatment	Severity of postoperative delirium on postoperative day 1 to 7 will be defined according to MDAS.	7 days after surgery
