What causes a sudden coma or unconscious?
Coma refers to the severe impairment of consciousness caused by the impairment of higher central structures and functional activities (consciousness, sensation and movement) due to various reasons, and is an extremely inhibited state of higher neural activity, which is mainly manifested as non-responsiveness to various external stimuli, and can be accompanied by motor, sensory, reflex dysfunction and urinary and urinary incontinence. Due to the acute onset, complexity, rapid development of the disease, high risk, multidisciplinary and multi-specialty, the case fatality rate is high.
Common causes of coma** can be broadly divided into five categories:
Infectious central nervous system diseases: such as meningococcal meningitis, other purulent or tuberculous meningitis, B viral encephalitis and other encephalitis, infectious toxic encephalopathy and Reye syndrome, brain abscess, cryptococcal meningitis, etc.
Noninfectious central nervous system diseases: cerebrovascular disease is more common.
Cerebrovascular disease, along with cancer and heart disease, has become one of the three major diseases that endanger human health. China is a country with a high incidence of cerebrovascular diseases, and in recent years, the incidence of cerebrovascular diseases has shown a trend of younger age. Cerebrovascular diseases can occur all year round, but according to surveys, more than half of cerebrovascular diseases occur in late autumn and early winter when the climate changes abruptly, indicating that cerebrovascular diseases are related to climate.
Causes of cerebrovascular disease in autumn and winter: low temperature in autumn and winter, after the human body is stimulated by cold, it will lead to changes such as vasoconstriction and increased blood pressure, which will induce cerebral hemorrhage or ischemic cerebrovascular disease; In autumn and winter, the climate is dry, and the human body consumes a lot of water, which is easy to cause a lack of water in the body and lead to blood viscosity; In autumn and winter, the temperature changes drastically, and the elderly have poor adaptability to changes in the external environment, especially the patients with hypertension, coronary heart disease, diabetes, atherosclerosis, etc., who encounter cold stimuli, which increases the risk of cerebrovascular coma.
Poisoning includes organophosphate pesticide poisoning, alcohol poisoning, lead poisoning, gas poisoning, drug poisoning, etc. It refers to the process of chemical substances that can cause body dysfunction, structural damage or even death in trace amounts, acting on the body surface or entering the body through various ways to cause morbidity or death, which is the central issue of toxicology research. It should be treated on a case-by-case basis.
non-central nervous system disease; Metabolic acidosis, diabetic coma, hypoglycemia, uremia and hepatic encephalopathy.
Secondary hypoxia of the central nervous system: severe asphyxia (including neonatal asphyxia), status convulsions and shock, certain arrhythmias (e.g., Ah-Si syndrome), and some cyanotic congenital heart disease (e.g., tetralogy of Fallot).
