The temperature in Guangzhou has been low around the Spring Festival this year. In addition to the increased incidence of cardiovascular and cerebrovascular diseases, the incidence of carbon monoxide poisoning has also increased rapidly. Experts say that patients who are sent to hospital emergency departments because of carbon monoxide poisoning are mainly young people and children. Because the gas water heater in the rental house or the old-fashioned residential shower room is installed in the house, and there is no ventilation device, the weather is cold, the doors and windows are closed, and the gas is not burned enough, resulting in a large amount of carbon monoxide, resulting in poisoning.
Insufficient gas combustion
Carbon monoxide can cause poisoning
The 12-year-old girl took a mobile phone in the rental house to listen to music and took a shower. It took a long time to wash it. The family’s listening to music has been ringing, and when it was suspected, it was discovered that the child was poisoned by gas. When sent to the hospital, the person was already in a coma, and the lips and skin showed a typical cherry red after carbon monoxide poisoning. Fortunately, it was found to be timely, but it was not difficult.
When it comes to carbon monoxide poisoning, many people think that it is caused by gas leakage. However, in fact, the main cause of carbon monoxide poisoning is the incomplete combustion of carbon monoxide, not the gas leakage (most of the gas is methane and hydrogen sulfide, and the toxicity is not high). . Chen Dexiong, deputy director of the emergency department of the Third Affiliated Hospital of Guangzhou Medical University, said that after carbon monoxide is inhaled by the body, the affinity of carbon monoxide and hemoglobin is 250-300 times higher than that of oxygen and hemoglobin, which not only blocks the combination of oxygen and hemoglobin. And carbon monoxide combined with hemoglobin is difficult to dissociate, making oxygen unable to transport to the body cells through hemoglobin, the direct result of the body is hypoxia. The harm of hypoxia to humans can be fatal, and the heavy one will lead to hypoxia in the brain, leading to irreversible necrosis of brain cells, sequelae such as dementia and unresponsiveness.
poisoned by carbon monoxide
The sooner the intervention, the less sequelae
Chen Dexiong said that the symptoms of carbon monoxide poisoning are divided into three levels, which are related to sequelae:
First, light: Poisoning time is still short, manifested as headache dizziness, palpitations, nausea, vomiting, limb weakness, short-term fainting, but at this time the mind is still awake. As long as you get rid of the poisoned environment and inhale fresh air, the symptoms will quickly disappear, and generally no sequelae will be left.
Second, medium: Poisoning time is a little longer, there may be collapse or coma, the skin and mucous membranes appear cherry red. If the rescue is timely, it can be quickly awake, fully recovered within a few days, and generally no sequelae.
Third, heavy: Poisoning time is too long, excessive carbon monoxide inhalation, deep coma, various reflexes disappear, incontinence, cold limbs, blood pressure, shortness of breath, can be life-threatening. Carbon monoxide poisoning takes too long, often leaving sequelae such as dementia, memory and comprehension, limb paralysis.
He reminded that if a suspected poisoned patient is found, the patient should be quickly transferred to a place with fresh air, rest in bed, keep warm, and keep the airway open. Call 120 quickly and ask a professional emergency responder.
Old-fashioned houses, rental houses
Installable carbon monoxide alarm
To prevent carbon monoxide poisoning, Chen Dexiong reminded to pay attention to the following two points:
One is to increase safety awareness, especially when using gas water heaters, to place the gas bottle outside the confined space. Do not close the bathroom doors and windows when showering in winter, do not take too long shower time. In addition, do not use in-line water heaters and flue-type water heaters. It is best to install water heaters for professional installation. Do not install, dismantle or modify the burning appliances yourself.
The second is to install a carbon monoxide alarm where carbon monoxide may be produced. Author: Yu Liang
