Symptoms and emergency treatment of biogas poisoning

Biogas is a kind of mixed gas produced by organic matter through microbial fermentation under anaerobic conditions. Biogas poisoning refers to acute systemic poisoning caused by inhalation of mixed gases remaining in the biogas digester during the process of clearing the biogas digest. let's take a look at the symptoms of biogas poisoning and first aid treatment.

How does biogas poison people?

The main components of biogas are methane, carbon dioxide, nitrogen, hydrogen, carbon monoxide and hydrogen sulfide. Methane is a kind of colorless and tasteless gas, which is the main component of natural gas and coal gas. it widely exists in natural gas, gas, biogas, silt ponds and closed pit wells, ponds, coal mines and coal depots. If the concentration of methane in the above ambient air is high, which reduces the oxygen content, it will suffocate people and, in serious cases, will lead to death. If the methane content in the air reaches 25-30%, it will cause headache, dizziness, nausea, inattention, incoordination, fatigue, weakness of limbs and other symptoms. If the content of methane in the air is more than 4550%, it will cause dyspnea, tachycardia, coma and suffocation due to severe hypoxia.

What are the symptoms of biogas poisoning?

Patients with mild biogas poisoning are characterized by headache and dizziness, moderate poisoning patients can see facial flushing, rapid heartbeat, sweating more, severe poisoning patients are more sinister, such as deep coma, elevated body temperature, rapid pulse, shortness of breath, and fecal incontinence at the same time. If this kind of patient is not rescued in time, he will die because of respiratory paralysis. Although some patients have been rescued from danger, they will inevitably leave sequelae such as forgetfulness and mental disorders.

Emergency treatment of biogas poisoning

1. Quickly remove the victim from the scene (rescuers must wear aerobic masks) and call for help to "120".

2. Inhale oxygen and send hyperbaric oxygen chamber under certain conditions.

3. Artificial respiration, endotracheal intubation if necessary, and administration of stimulant lobeline.

4, prevention and treatment of brain edema, 20% mannitol 250 ml intravenous injection and furosemide 20 mg intravenous injection.

5. Dexamethasone 20-40 mg was added to 10% glucose injection in 500ml intravenous drip, and ATP, coenzyme A, cytochrome C and so on.

How to prevent biogas poisoning?

1. When cleaning the biogas digester, open the discharge, inlet and valve of the biogas two days in advance to let the biogas remaining in the biogas digester run away through air circulation.

2. The operation of the pool should not be too hasty, and the time should not be too long. If you feel uncomfortable, you should immediately get out of the pool and leave the marsh source.
