Analysis and Record Intraoperative Bispectral Index of Patients of Thoracic Surgeries

• Conditions: Bispectral Index and Neurmuscular Monitoring Data in Anesthetized Patients
• Interventions: Device: Bispectral index

• Registration Number: NCT04394364
• Lead Sponsor: Taipei Veterans General Hospital, Taiwan

Brief Summary

Bispectral index(BIS) is commonly used to monitor the depth of anesthesia. The electroencephalographic signal is collected and analyzed by the device, resulting a number related to the awareness of the patient. Electromyography is also recorded. The aim of the study is recording and analyzing the data of BIS and try to find it's relation to intraoperative neuromuscular blockade.

Primary Outcome Measures

Name	Time	Method
Establishing the predicting model of intraoperative electromyographics of BIS monitor and train-of-four of neuromuscular transmission monitor	six months	We will collect EMG activity of bispectral index and train-of-four/count of neuromuscular trasmission monitor in patients undergoing pulmonary surgeries. Total intravenous anesthesia will be given to all included patients, and data will be collected since the induction of anesthesia until extubation of endotracheal tube.By statistical methods, we expect to establish the model predicting intraoperative neuromuscular blockade by EEG activity of BIS monitor.
