What to do if you get gas poisoning

Gas poisoning is mainly colorless, tasteless and odorless, but when carbon-containing substances burn in an environment with insufficient oxygen, they will produce such symptoms. If the ventilation is not good or some heaters are used improperly, it will lead to such phenomena. In severe cases, the symptoms are very obvious, and the changes in symptoms and signs in daily life are also very large, which will cause changes in mental state, convulsions, coma, and gastrointestinal symptoms.

Some of the more critical symptoms of brain hypoxia and poisoning are also gas poisoning. Many people in daily life are more concerned about gas poisoning. The main thing for first aid treatment is to move the patient to some secluded place as soon as possible, open some doors and windows, or breathe some fresh air.

The first step in treatment is to move the patient to a CO2-free place or open the doors and windows to breathe fresh air as soon as possible; if there are temporary difficulties, the rescuer puts on a mask himself and then immediately puts on an oxygen mask for the patient until the patient is moved to a safe place.

The second and most important step is to give the patient high-concentration oxygen via nasal cannula or mask (normative oxygen therapy). The quickest way to get CO out of the blood is with treatment in a hyperbaric oxygen chamber. All patients suspected of CO poisoning should be treated in a hyperbaric oxygen chamber as soon as possible, preferably within 6 hours of poisoning. Hyperbaric oxygen therapy should be given regularly to CO poisoning patients with coma, cardiovascular disease or cardiac ischemia and persistent mental and/or neurological disorders. Hyperbaric oxygen therapy can shorten recovery time and reduce the occurrence of delayed encephalopathy. For delayed encephalopathy caused by CO poisoning, hyperbaric oxygen therapy may be effective for patients with a course of less than six months, and should also be actively sought within one year. A recent study shows that hyperbaric oxygen therapy is safe for pregnant women.

In addition to the above measures, other supportive therapies should be adopted, including: ① Use of energy mixtures. ② Use large amounts of vitamin C: 1 to 2 g each time, add to liquid and drip intravenously, 1 to 2 times a day. ③Corticosteroids can reduce tissue reactions and are effective in preventing and treating cerebral edema when used in combination with mannitol. Dexamethasone is generally the first choice, 10 mg intravenous injection, 2 to 3 times/d. ④ Dextran 40 (low molecular weight dextran): It can be used especially in cases of hypotension or shock. This drug is effective not only for acute CO poisoning, but also for delayed encephalopathy. ⑤If the patient has high fever, convulsions, severe cerebral edema and central respiratory failure, hibernation therapy may be considered. ⑥ Anti-infection: If infection does exist, antibacterial treatment can be carried out. However, it should be noted that a slightly higher body temperature and slightly higher peripheral blood white blood cells and neutrophils may be the body's stress response and antibacterial treatment is not necessary. ⑦ Correct acid-base and electrolyte imbalance: Make judgments based on the results of arterial blood gas and synchronized electrolytes and take corresponding measures. It should be noted that it is not necessary to be "aggressive" in correcting mild acidosis, so as to avoid alkali poisoning and aggravating tissue hypoxia. ⑧For comatose patients, brain protein hydrolysate (cerebrolysin) and citicoline (cytidylinositol) can be used for treatment. Drugs such as ethamethiocarbamide (ethaminethiocarbamide) and meclofenoxate (clofenoxate) often have little effect and may even cause convulsions in patients, so they should be used with caution. ⑨ Exchange transfusion and hypothermic perfusion can be used as auxiliary measures to treat patients with CO poisoning. The pros and cons of this therapy should be noted. ⑩Other symptomatic treatments.

The above is the phenomenon of gas poisoning. Diet and health care are also very important. It is mainly manifested in the fact that many people in daily life are more concerned about gas poisoning. How to provide first aid and treatment is mainly to move the patient to some secluded place as soon as possible, open some doors and windows, or breathe some fresh air. Appropriate supplementation of some vitamins can be a preventive care. It is necessary to prevent pipe leaks and ventilate.
