What should we do to check for carbon monoxide poisoning? Believe that this is a problem that many people are concerned about and care about, carbon monoxide poisoning is a common phenomenon in our life, will cause serious damage to the patient´s health, affect the patient´s normal life. To avoid carbon monoxide poisoning, we can install a carbon monoxide alarm.
1. The amount of carbon oxygen hemoglobin in blood can reach 5% ~ 10% in normal blood, with a small amount of endogenous carbon monoxide, about 4.4% ~ o. 7%. In the case of mild carbon monoxide poisoning, the amount of carbon oxygen hemoglobin in the blood can be higher than 10%, moderate poisoning can be higher than 30%, and severe poisoning can be higher than 50%. However, the determination of hemoglobin in blood must be timely, and the carbon oxygen hemoglobin can be reduced to normal after 8 hours of contact with carbon monoxide, and it is not parallel to the clinical symptoms.
2. Electroencephalogram (eeg) reported that 54 ~ 97% of patients with acute carbon monoxide poisoning were able to detect abnormal electroencephalogram (eeg), which showed a low amplitude of slow wave. In general, the theta ripples in the frontal and temporal areas are often associated with clinical mental disorders. Some coma patients can also have special three-phase wave, similar to liver coma time wave type? Quot; Pseudomonas spines or slow waves, or slow waves, but different from paroxysmal epileptics. In some cases of acute carbon monoxide poisoning, an intelligent disorder occurred in the later stage of the patient.
3, the brain evoked potential examination acute and delayed encephalopathy of carbon monoxide poisoning is visual evoked potential vep100 latent ShiYanChang, abnormal rate were 50% and 68% respectively, recovery is down to 5% and 5% respectively. Median nerve induction potential (sep) was found to be selectively impaired in middle and long dives such as n32, and the abnormality rate of both patients was more than 70% and recovered with the improvement of consciousness. The abnormality of the brain stem auditory evoked potential (baep) is closely related to the degree of consciousness disorder, which is parallel to the outcome of the poisoning. Three kinds of brain evoked potentials can be used simultaneously, often can raise abnormal detection rate. Are you having trouble with your brain? Quot; During the pseudo - period, the patient was observed in dynamic observation, such as the occurrence of abnormal brain evoked potentials, and the absence of symptoms often predicted the possibility of delayed encephalopathy. After regaining consciousness in patients with acute carbon monoxide poisoning event related potential (p300) study, found that more than one-third (p300) in patients with latent significantly longer, and neurobehavioral tests reflect brain, memory and movement speed index anomalies have significant correlation.
4. With the development and improvement of brain imaging technology, there have been many reports on ct and mri in the past 10 years. China reported 100 cases of carbon monoxide poisoning patients in acute phase and appeared to be the time delayed encephalopathy craniocerebral ct examination, see the main exception is bilateral cerebral subcortical white matter and pallidum or internal capsule appear roughly symmetrical reduce area density, the late visible ventricle enlarge or brain ditch broadening, the abnormal rate was 41.2% and 41.2% respectively. The prognosis of brain ct was better than that of the non-changers, and the coma time of the ct abnormality was more than 48 hours. However, there was no ct change in the early stage of brain disease, and the above ct abnormality usually occurred within 2 weeks of the symptoms of delayed encephalopathy. Therefore, brain induced potential and electroencephalogram were not as sensitive. Acute phase ct has shown holding the white matter abnormalities in patients with cerebral cortex, its recovery than delayed encephalopathy with white matter is unusual for the poor, patients with two types of pathological changes of white matter is different, the former may and myelin sheath and axon damage, which may be more than just for the myelin sheath of depigmentation. Mri is superior to ct in showing the brain lesions of carbon monoxide poisoning, both of which are beneficial to the differential diagnosis of other brain diseases.
The above is the small make up to introduce the carbon monoxide poisoning should be done after inspection, I believe you all know, everyone must be aware of the dangers of carbon monoxide gas to people body, try not to use coal to heat, if use also should pay attention to indoor ventilation in time, carbon monoxide alarm installation, keep the air fresh, so as to better prevent carbon monoxide poisoning.
