Anesthesia state monitoring method and device

Abstract

The invention discloses an anesthesia state monitoring method and device, and relates to the field of anesthesia monitoring. The method comprises the following steps: a signal collection step: acquiring a heartbeat signal and a breathing signal; an analysis processing step: processing the heartbeat signal and the respiration signal to obtain a cardiopulmonary index and a damage irritation index; and a result evaluation step: determining an anesthesia state based on the cardiopulmonary index and the injury irritation index. The anesthesia state monitoring method and device provided by the invention can monitor comprehensive anesthesia depth, can recognize changes of the sedation degree and the analgesia degree, meet the requirement for clinical anesthesia, and provide a reference for infusion of anesthesia administration, so that the most suitable anesthesia state is provided for anesthetized patients, and too deep or too shallow anesthesia is avoided.

Description

technical field [0001] The invention relates to the field of anesthesia monitoring, in particular to a method and device for monitoring an anesthesia state. Background technique [0002] The meaning of general anesthesia is to use drugs or other methods to temporarily deprive the patient of feeling as a whole, so as to achieve painless surgical treatment. The realization of general anesthesia has the following requirements: to make the patient lose consciousness (sedation); to eliminate pain (analgesia) ; causing immobility (muscle relaxation); and eliminating unnecessary reflexes, such as pharyngeal spasms and cardiac 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-anesthesia, and 10% of patients are under shallow and deep anesthesia. When the sedation and anesthesia are too deep, the overdose of the drug w...

In terms of analgesia, the indicators that anesthesiologists pay attention to include conventional physiological parameters such as heart rate and mean arterial blood pressure (MAP), but they are mainly judged based on the long-term clinical experience of anesthesiologists, and there is no objective indicator

In recent years, some researchers have proposed that nociception index (ANI) can be used to judge the degree of analgesia in anesthesia. However, the current clinical research on ANI is still in the early stage, and there are few relevant literature reports. There is also a lack of ANI and chronic pain clinically. Relevant clinical studies of the relationship
