Many people inhale "laughing gas" because they will feel excited and relaxed after inhaling, and they will want to laugh. ? Because "laughing gas" has a relaxing effect, it will also be used in stomatology to play an anesthetic role.
"? In foreign countries, especially in the United States, the use of nitrous oxide in medicine has become more common. At present, it is in the initial stage in China and will develop gradually. Pu Jianjun said that "nitrous oxide" can be used as an auxiliary anesthetic to play a calming role. The use of nitrous oxide does not mean that anesthesia is not needed, it is just an auxiliary anesthesia.
Usually used with oxygen, so that the whole treatment process will be more comfortable. Now some hospitals have "comfortable dentistry" and use "nitrous oxide" in dental clinics. ?
After inhaling nitrous oxide, the human body absorbs it in the lungs. At this time, because the concentration in the alveoli is higher than that in the blood, the alveoli will exchange gas with the cells on the lung surface, and nitrous oxide will enter the blood, and then the nitrous oxide in the blood will be transported to all parts of the body, thus entering the brain, achieving the effect of relaxation, mainly analgesia, followed by sedation.
Because "nitrous oxide" is relatively safe, some parturients also use nitrous oxide to control the concentration of funny gas cylinders during childbirth, and when combined with oxygen, patients can achieve the sedative effect by inhaling it themselves.
The main risk of using nitrous oxide is fear of hypoxia. When nitrous oxide is used in general medical clinics, it is safe to mix it with oxygen. If the concentration of nitrous oxide is high and the concentration of oxygen is low, there will be hypoxia.
Therefore, when nitrous oxide and oxygen are used together, there will be a linkage switch device, which will automatically adjust the concentration to prevent mistakes.
Laughter can produce a feeling of excitement and relaxation, so many people will smoke it themselves. However, each drug has adverse reactions and adaptability. Taking nitrous oxide directly is risky. If it is not for medical use, poor concentration control will be life-threatening.
"Because nitrous oxide has a strong diffusion ability, although nitrous oxide also emits a part from the skin surface, it will enter the abdomen, stomach and other places directly, and there may be abdominal distension; At the same time, there is also a risk of rupture of pulmonary bullae and gastric rupture, and there is a risk of suffocation. " ?
It is not recommended to take a large amount of nitrous oxide for a long time, especially for pregnant women in the early pregnancy, and should avoid contact with nitrous oxide.
As a medicine, "nitrous oxide" will have a certain impact on health. If nitrous oxide is used improperly, there will be risks such as abdominal distension and alveolar burst. Excessive inhalation of nitrous oxide may also lead to suffocation.
In view of the possible risks of nitrous oxide, the police have said that it may be a new drug, but the specific nature of nitrous oxide has not yet been determined.
