Anesthesia state monitoring method and device

Abstract

The invention discloses a method and device for monitoring an anesthesia state, and relates to the field of anesthesia monitoring, comprising the following steps: a signal acquisition step: acquiring an electroencephalogram signal, a heartbeat signal and a breathing signal; an analysis and processing step: obtaining an electroencephalogram signal through feature extraction. EEG index; cardiopulmonary index is obtained by analyzing heartbeat signal and breathing signal; result evaluation step: determine anesthesia state based on cardiopulmonary index and EEG index. The invention can simultaneously monitor the comprehensive anesthesia depth and realize the identification of changes in the sedation degree and analgesia degree, so as to meet the needs of clinical anesthesia, and can provide reference for the infusion of anesthesia drugs, thereby providing the most suitable anesthesia for anesthetized patients. state, avoid too deep or too shallow anesthesia.

Description

technical field [0001] The invention relates to the field of anesthesia monitoring, in particular to an anesthesia state monitoring method and device. Background technique [0002] General anesthesia is the use of drugs or other methods to temporarily make the patient lose all sense of the whole, in order to achieve the purpose of painless surgical treatment. The realization of general anesthesia requires the following: to cause the patient to lose consciousness (sedation); to eliminate pain (analgesia); to induce immobility (muscle relaxation); and to eliminate unnecessary reflexes such as pharyngeal spasms and arrhythmias (reflex inhibition) . According to clinical statistics, less than two-thirds of patients can receive high-quality anesthesia services, about 14% of patients are over-anesthetized, 16% of patients are under-anaesthetized, and 10% of patients are under shallow and deep. The sedation and anesthesia are too deep, and the overdose of the drug will cause the ...

Problems solved by technology

In terms of analgesia, the indicators that anesthesiologists pay attention to include heart rate, mean arterial blood pressure (MAP) and other routine physiological parameters. Judging by the long-term clinical experience of anesthesiologists, there is no objective indicator

[0005] However, currently commonly used anesthesia monitoring instruments, such as BIS, ECG monitors and other equipment are configured independently, and medical resources are not well integrated into one; and the data compatibility between monitoring equipment is poor, and various monitoring connection lines are intricate. Make the operation unable to achieve multi-dimensional, multi-parameter automatic control

In addition, BIS monitoring equipment is expensive, and the hospital cannot monitor the depth of anesthesia for all operations, which also increases the treatment cost of patients
