Anesthesia depth monitoring method

Abstract

The invention discloses an anesthesia depth monitoring method. The anesthesia depth monitoring method monitors anesthesia depth by detecting isoprene content in a patient's breath. By detecting the isoprene content in the patient's breath, a real-time noninvasive anesthesia depth monitoring method is established; and the established anesthesia depth monitoring method is far superior to electroencephalography monitoring from a practical point of view. When electroencephalography monitoring is being performed, brain electrodes must be attached to surface areas of corresponding brain regions of the patient; and thus, anesthesia depth cannot be monitored at the corresponding points of the brain in craniocerebral surgery and facial surgery. On the contrary, the method for monitoring the anesthesia depth by detecting the isoprene content in the patients' breath is suitable for any patients for gas sample can be extracted from the patients' breath, no matter the patients are in spontaneous breathing or machine-controlled breathing during operation, so as to be subjected to gas chromatographic analysis; and thus, the method is not limited by conditions, such as surgery type, patient age and the like.

Description

technical field [0001] The invention relates to a method for monitoring the depth of anesthesia. Background technique [0002] Intraoperative awareness is the recovery of consciousness during general anesthesia. Intraoperative awareness can cause serious emotional and mental (mental) health problems. 30% to 50% of patients with intraoperative awareness have post-traumatic stress disorder (post traumatic stress disorder). -traumatic stress disorder, PTSD), which manifests as psychological and behavioral abnormalities, sleep disorders, anxiety and dreaminess, and psychosis, and its symptoms can last for months or years. The incidence of intraoperative awareness is about 0.1% to 0.4%, and it can be as high as more than 1% in high-risk groups (cardiac surgery, obstetric surgery, emergency surgery, shock patient surgery, etc.), based on the huge amount of general anesthesia operations every year, especially for high-risk patients. For the population, the actual number of intraop...

AI Technical Summary

Problems solved by technology

[0003] EEG monitoring, as the most commonly used technology for testing the depth of anesthesia, has certain shortcomings. For example, EEG monitoring must be done by attaching brain electrodes to the body surface of the corresponding brain area of ​​the patient. Therefore, craniocerebral surgery and facial surgery cannot be passed. Noise point monitoring to understand the depth of anesthesia
