Effects of Preoperative Sleep Disorders on Perioperative Anesthesia Depth and Recovery Quality in Patients Undergoing Noncardiac Surgery
Recruiting now
Conditions studied: Emergence Time
In brief
A Single-Center, Prospective Observational Cohort Study Comparing Perioperative Electroencephalographic Anesthesia Depth Parameters (Electroencephalographic Index, SE/RE Entropy, Burst Suppression Ratio) Between Patients With Preoperative Sleep Disorders and Those Without; To Identify the Independent Effects of Preoperative Sleep Disorders on the Speed of Electroencephalographic Recovery During Emergence, Electroencephalographic Status at Extubation, Intra-PACU Electroencephalographic Fluctuations, and Quality of Emergence.
