[Comparative Evaluation of Encephalon State Index and Bispectral Index in Monitoring the Depth of Anesthesia during the Surgical Anesthesia Stage].

Objective: Evaluate the performance of the encephalon state index (ESI) in depth of anesthesia monitoring during clinical surgery, compared with the bispectral index (BIS).

Methods: ESI and BIS data were collected from 60 patients in a single-center clinical trial to compare their efficacy in measuring the depth of anesthesia.

Results: Consistency analysis revealed mean differences and standard deviations of －0.

Effects of hydromorphone-based patient-controlled intravenous analgesia on postoperative hypoxaemia: a randomised controlled non-inferiority clinical trial.

Objective: This study aimed to compare the effects of patient-controlled intravenous analgesia (PCIA) with and without low-basal infusion on postoperative hypoxaemia.

Design: A randomised parallel-group non-inferiority trial.

Setting: The trial was conducted at a grade-A tertiary hospital from December 2021 to August 2022.

[Development of Vital Signal Monitoring System Based on Accelerometer].

Objective: Reduce the number of false alarms and measurement time caused by movement interference by the sync waveform of the movement.

Methods: Vital signal monitoring system based on motion sensor was developed, which collected and processed the vital signals continuously, optimized the features and results of vital signals and transmitted the vital signal results and alarms to the interface.

Results: The system was tested in many departments, such as digestive department, cardiology department, internal medicine department, hepatobiliary surgery department and emergency department, and the total collection time was 1 940 h.

Monitoring the Depth of Anesthesia Through the Use of Cerebral Hemodynamic Measurements Based on Sample Entropy Algorithm.

Objective: The aim of this study is to explore the relationship between the depth of anesthesia and the cerebral hemodynamic variables during the complete anesthesia process.

Methods: In this study, near-infrared spectroscopy signals were used to record eight kinds of cerebral hemodynamic variables, including left, right, proximal, distal deoxygenated (Hb) and oxygenated (HbO) hemoglobin concentration changes. Then, by measuring the complexity information of cerebral hemodynamic variables, the sample entropy was calculated as a new index of monitoring the depth of anesthesia.

[Effects of electroacupuncture at Fenglong (ST 40) on SOD and MDA in different organs of the hyperlipemia rat].

Objective: To probe into the target organ of Fenglong (ST 40) and the mechanism in resolving phlegm.

Methods: Thirty SD rats were randomly divided into 3 groups, a blank control group, a model group and a Fenglong group, 10 rats in each group. The hyperlipemia rat model was prepared by feeding high fat forage.
