Lead Sponsor
Beijing Tiantan Hospital
Brief Summary

Postoperative delirium (POD) is a common complication, and the incidence of POD after deep brain stimulation(DBS) implementation ranges from 10% to 40%. Previous studies suggested that aging and existing non-motor symptom were independent risk factors for POD after supratentorial tumor resections. Therefore, patients undergoing DBS are high-risk populations for POD. A lot of trials show that dexmedetomidine might help to reduce the incidence of delirium in patients undergoing non-cardiac surgery. However, the impact of dexmedetomidine on POD for patients undergoing DBS was seldom reported. The purpose of this study was to investigate the effect of dexmedetomidine on POD in patients with Parkinson' Disease undergoing DBS.

Primary Outcome Measures
NameTimeMethod
The incidence of postoperative delirium.Postoperative 5 days

Postoperative delirium is assessed by the combination of the Richmond Anxiety Scale (RASS) and the Confusion assessment method for intensive care unit (CAM-ICU) or the 3-minute diagnostic interview for CAM (3D-CAM) as applicable.

Secondary Outcome Measures
NameTimeMethod
Quality of sleepthe second and the third day after surgery

Quality of sleep will be evaluated with the Richards Campbell sleep questionnaire (RCSQ).

Postoperative painwithin 3 days after surgery.

Postoperative pain will be assessed with Numerical Rating Scale (NRS). Postoperative analgesia will be recorded.

Quality of recovery.First day after surgery

Quality of recovery will be evaluated with 15-item quality of recovery questionnaire (QoR-15).

The severity of postoperative delirium.Postoperative 5 days

The severity of postoperative delirium will be assessed by Delirium Rating Scale-Revised-98.

Cognitive functionbefore surgery and 5 days after surgery

Cognitive function will be assessed using the Mini-Mental State Examination (MMSE) and the Montreal cognitive assessment-basic (MoCA-B).

Anxiety and depressionbefore surgery and 5 days after surgery

Anxiety and depression will be evaluated using Generalized Anxiety Disorder-7 (GAD-7) and Patient Health Questionaire-9 items (PHQ -9).

Parkinson's disease related statusbefore surgery and 5 days after surgery

Parkinson's disease related status will be evaluated by Movement Disorder Society-Sponsored Revision Unified Parkinson's Disease Rating Scale (MDS-UPDRS).
