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.

The BIS monitor will be attached to patients' forehead before anesthetized and kept until the end of the surgery

Establishing the predicting model of intraoperative electromyographics of BIS monitor and train-of-four of neuromuscular transmission monitor
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.
