Doctor Nguyen Duc Loc, Department of Internal Resuscitation and Anti-Poison, Intensive Care Center, 108 Central Military Hospital said that recently, the Department of Internal Resuscitation and Anti-Poison, has received two cases living in Son Dong district, Bac Giang province who were suffocated after going down a deep well to clean it.
Accordingly, on May 4, Mr. A went down a nearly 10m deep well to clean the well and did not come up to the surface for a long time. Mr. X, 36 years old, and Mr. N, 45 years old, climbed down to save him but discovered that Mr. A had died.
When someone suffocates in a deep well, everyone needs to stay calm and give first aid to avoid death (photo source: Hospital 108).
At that time, Mr. X and N both had difficulty breathing and felt dizzy. They were pulled to the ground and given artificial respiration by local people on the spot. They received first aid at the local medical facility and were then transferred to the Department of Internal Medicine and Anti-Poisoning.
According to Dr. Le Lan Phuong - Director of the Intensive Care Center, "In deep well environments, especially wells that have been covered for a long time and are rarely used, the products of decomposition of organic matter are toxic gases such as methane (CH4), carbon dioxide (CO2), carbon monoxide (CO) and hydrogen sulfide (H2S) ... which have a heavier density than oxygen, the deeper the concentration is, the more concentrated it is.
The victims died due to lack of oxygen (O2) and inhalation of the above toxic gases. In addition, in areas with many coal mines, oil ore or landfills, agricultural waste, deep wells often have a lot of methane gas.
This is a toxic gas that can quickly kill a person if it reaches a high concentration. Therefore, people need to be careful when intending to go down deep wells in these areas.
To prevent suffocation accidents in deep wells, doctors at the Poison Control Center say that people need to do the following: Prepare all necessary tools before going down the well, such as having full protective gear and gas masks before going down the well.
Normally, the majority of people do not have the above items, however, the above problems can be overcome in the following simple ways:
Cut a large, leafy branch, tie a long rope to it and lower it to the bottom of the well. Pull it up and down many times to ventilate the bottom of the well.
A better way is to use a pure oxygen aerator to pump air down the well.
You should prepare a rubber tube to both conduct air from the ground for breathing and to signal people above in case of an accident.
People can light a candle or lamp and slowly lower it down to the water surface at the bottom of the well. If the candle still burns normally, the air at the bottom of the well has enough oxygen for breathing. On the contrary, if the candle only flickers and then goes out, we should not go down the well.
You can also drop a chicken or a bird down close to the surface of the well. If the animal suffocates, it means there is a lot of toxic gas in the well.
If, in case of encountering a scene where someone is suspected of suffocating in a well, the next person must absolutely not go down the well immediately to rescue them. The first responder must immediately call the Fire Prevention, Fire Fighting and Rescue Police (phone number 114) for support.
If the victim is still conscious, lower the rope into the well to pull him up. If the victim is unconscious, prepare and check for safety before deciding to go down the well.
The rescuer uses one hand to pinch the victim's nostrils closed, the other hand pushes the chin hard to open the victim's mouth. Then the rescuer takes a deep breath, puts his mouth close to the victim's mouth, then blows hard, continuously blows 2 breaths for adults, 1 breath for children under 8 years old, observe the victim's chest rise to do it correctly, then let the victim's chest fall back down and then blow again.
Perform the above movements continuously at the following rate: adults and children over 8 years old perform about 15-20 times/minute, children under 8 years old perform mouth-to-mouth resuscitation 20-30 times/minute. You can perform mouth-to-mouth and nose-blowing movements in the same way.
The best first aid for a victim after reaching the ground is to perform artificial respiration on the spot, then take the victim to the nearest medical facility.
Gas poisoning in deep wells is not only life-threatening for the victim himself but also poses a potential risk to rescuers. In fact, preventing this problem manually is very simple.
However, not everyone knows these methods as well as how to rescue victims of suffocation in deep wells.
