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. and nociceptive irritation index; outcome evaluation steps: determine anesthesia status based on cardiorespiratory index and nociceptive irritation index. The anesthesia state monitoring method and device provided by the present invention can simultaneously monitor the comprehensive anesthesia depth, and realize the identification of changes in the degree of sedation and analgesia, meet the needs of clinical anesthesia, and provide anesthesia drug infusion. In order to provide the most suitable anesthesia state for anesthetized patients, 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] The meaning of general anesthesia is the use of drugs or other methods to temporarily make the patient lose feeling as a whole, in order to achieve the purpose of painless surgical treatment. The realization of general anesthesia has the following requirements: make the patient lose consciousness (sedation); eliminate pain (analgesia) ; causes the body to remain immobile (muscle relaxation); and eliminates 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. When the sedation and anesthesia are too deep, the overdose of the...

Problems solved by technology

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
