Objectives: To explore the relationship between the Observer's Assessment of Alertness/Sedation (OAAS) score and the bispectral index (BIS) during propofol titration for general anesthesia induction and analyze the impact of BIS monitoring delay on anesthetic depth assessment.
Methods: This study was conducted among 90 patients (ASA class I-II) undergoing elective surgery under general anesthesia. For anesthesia induction, the patients received propofol titration at the rate of 0.

Objective: This study aimed to compare the clinical outcomes of midazolam and dexmedetomidine combined with ropivacaine-induced thoracic paravertebral nerve block (TPVB) in radical lung cancer surgery.
Methods: To retrospectively analyze the clinical data of elderly patients who underwent thoracoscopic radical lung cancer surgery from March 2020 to February 2023 in our hospital. All patients underwent a single two-site method of TPVB at the levels of T4 and T7 under ultrasound guidance.
Electroencephalography and Anesthetic Depth in Children Under 2 Years of Age: A Prospective Observational Study.

Department of Anesthesiology and Pain Medicine, Seoul National University Hospital, Seoul National University College of Medicine, Seoul, Republic of Korea.
Background: Processed electroencephalogram (EEG) indices are widely used to monitor anesthetic depth. However, their reliability in children under 2 years of age remains questionable. During anesthesia maintenance in this age group, processed EEG indices frequently exhibit unexpectedly elevated values that exceed the intended target range.

It helps to calm the nervous system, promotes relaxation, and offers comfort by blocking outside noise and distracting from pain. This can be helpful in managing preoperative anxiety and symptoms like hypertension and tachycardia.

Article Synopsis
- The study aimed to compare the effects of different anesthetics on two types of motor evoked potentials: transcranial (TcMEPs) and transesophageal (TeMEPs).
- The experiment involved anesthetizing pigs and measuring the responses of TcMEPs and TeMEPs at varying concentrations of desflurane and doses of propofol.
- The results showed that TeMEPs had significantly larger amplitudes than TcMEPs, indicating that TeMEPs are more resistant to anesthetic effects, making them a potentially better option for monitoring during surgery.
