Fig. 1 shows a monitoring and analyzing flow chart of the monitoring and analyzing system for body temperature and anesthesia recovery according to the present invention, which comprises the following steps:
step S1, regularly acquiring body temperature monitoring information of a patient, and determining a body temperature adjusting state of the patient in an anesthesia awakening process according to the information; s2, acquiring electroencephalogram signals with the frequency of 0.8-32 HZ and frontal muscle electrical signals with the frequency of 32-47 HZ of the patient, and determining the state entropy and the reaction entropy of the anesthesia awakening state according to the electroencephalogram signals and the frontal muscle electrical signals;

and S5, determining the anesthesia awakening evaluation degree of the patient in each acquisition time period according to the values of the differential body temperature value, the analgesia effect expression value, the state entropy and the reaction entropy of the patient, evaluating and displaying a comprehensive anesthesia awakening index, helping a doctor analyze a brain temperature regulation mechanism, the suppression condition of cerebral cortex in operation and the comprehensive expression of the forehead skeletal muscle excitation degree of the patient in the anesthesia awakening state process according to the comprehensive anesthesia awakening index of the patient, and analyzing the brain activity rule of the patient and the quantitative expression value of the body temperature change involved by the lateral view brain-derived neurotrophic factor positive neurons in the hypothalamic anterior region when the patient is awakened from anesthesia.
Specifically, the detailed process of each step of the invention is as follows: step S1:
the invention firstly acquires the body temperature monitoring information of the patient periodically and determines the body temperature adjusting state of the patient in the anesthesia awakening process according to the information.
The body temperature monitoring information is obtained from the body of the patient at intervals of one minute within five minutesThe placed anal temperature probe acquires five rectal temperature monitoring values of the patient, the rectal temperature monitoring values are collected in the data acquisition module, data stream storage of historical rectal temperature monitoring values is realized through the data storage module, and the five rectal temperature monitoring values are recorded as

it should be noted that, in the above description, five rectal temperature monitoring values are adopted

And->
Figure SMS_27
The method is characterized in that the method is a normal value obtained by monitoring the anal temperature monitoring probe, when the temperature value obtained by monitoring the anal temperature monitoring probe is lower than 30 ℃ or higher than 45 ℃, an abnormal value at the position is removed in a linear interpolation mode, and vacancy value interpolation is carried out by combining two adjacent normal monitoring values.
Step S2:
the invention obtains the electroencephalogram signals with the frequency of 0.8-32 HZ and the frontal muscle electrical signals with the frequency of 32-47 HZ of a patient, and determines the state entropy and the reaction entropy of the anesthesia awakening state according to the electroencephalogram signals and the frontal muscle electrical signals.
It should be noted that the entropy index monitoring information is acquired by collecting electroencephalogram signals with frequency of 0.8-32 HZ and frontal muscle electrical signals with frequency of 32-47 HZ through three electrode plates adhered to the forehead of a patient, an entropy index analysis module quantifies the electroencephalogram signals by using a nonlinear analysis method, and state entropy and reaction entropy are acquired through digital processing, wherein the state entropy is used for reflecting the situation that cerebral cortex is inhibited in an operation, and the reaction entropy is used for reflecting the inhibition degree of the cerebral cortex and the excitation degree of forehead skeletal muscles in the operation. The neural activity has the characteristics of nonlinearity and irregularity, the entropy index is that an electroencephalogram signal is quantized by using a nonlinear analysis method, and an anesthesia depth value is measured by digital processing, and the operational principle is that the irregularity and the unpredictability of the signal are described by comprehensively analyzing an electroencephalogram signal EEG and a frontal muscle electrical signal FEMG. The entropy index is different from monitoring indexes BIS and AEP, and can reflect the anesthesia depth change and consciousness disappearance state of the patient at the same time: research shows that compared with BIS, when propofol is used for induction, the entropy index has higher accuracy than BIS sedation depth prediction, the influence of body position factors on the entropy index is smaller than that of BIS, and the response speed to the consciousness recovery of patients is more sensitive and quicker; compared with AEP, the entropy index has strong anti-interference capability, is slightly interfered by muscle activity and an electrotome in operation, has no sound stimulation, is suitable for patients with hearing impairment, and is a subcortical reaction of nociceptive stimulation body movement caused by intubation and skin cutting, and the reaction entropy in the entropy index can reflect subcutaneous electroencephalogram activity.
It should be noted that, the entropy index monitoring data may have an outlier exceeding a threshold caused by the use and function of an electrode, and such data is displayed and cleaned, so as to avoid the influence of the data on the evaluation and analysis of the subsequent anesthesia awakening.
And step S3:
the method carries out data cleaning on the obtained body temperature monitoring information and the entropy index information, and eliminates abnormal values and outliers.
And step S4:
in step S4, the body temperature monitoring information and the entropy index information of the patient are mainly obtained to obtain the differential body temperature value and the analgesia effect expression value, and the anesthesia state of the patient during anesthesia awakening is determined according to the numerical value of the state entropy.
It should be noted that the differential body temperature value is an average value of the anal temperature monitoring value of the patient obtained every other one minute within five minutes and the difference value of 30 ℃, and the analgesic effect expression value is an average value of the reaction entropy and state entropy difference values obtained every other 30 seconds within two minutes. The temperature of the rectum is the lowest temperature of the rectum for carrying out transient stopping circulation in shallow low-temperature stopping circulation anesthesia inner-covering type aortic arch replacement, and the rectum is easy to cause organ damage of low-temperature stopping circulation when the temperature is lower than the lowest temperature.
Step S5:
in step S5, according to the values of the patient 'S differential body temperature value, the analgesia effect expression value, the state entropy and the reaction entropy, the evaluation degree of the patient' S anesthesia awakening in each acquisition time period is determined, and the evaluation and display of the comprehensive anesthesia awakening index are performed, so that a doctor is helped to analyze the brain temperature regulation mechanism, the suppression condition of cerebral cortex in the operation and the comprehensive expression of the excitability of forehead skeletal muscle of the patient in the anesthesia awakening state process of the patient according to the comprehensive anesthesia awakening index of the patient, and the brain activity rule of the patient and the quantitative expression value of the body temperature change involved by the side-looking brain-derived neurotrophic factor positive neurons in the hypothalamic preoptic area when the patient is awakened from anesthesia.
It should be noted that, the patient anesthesia awakening assessment degree in each acquisition time period is analyzed by the numerical value of the comprehensive anesthesia awakening index, the anesthesia awakening assessment module is used for processing data from at least one component of the monitoring and analysis system for body temperature and anesthesia awakening, the anesthesia awakening state of the patient is assessed by the comprehensive anesthesia awakening index in combination with the entropy index monitoring information and the body temperature monitoring information, and the assessment mechanism of the comprehensive anesthesia awakening index is as follows:
