Medical benefits of nitrous oxide

Nitrous oxide (N2O) is used for anesthesia, which has no irritation to respiratory tract and no damage to the functions of important organs such as heart, lung, liver and kidney. Without any biological transformation or degradation in the body, most of them are still expelled from the body with the breath of the original drug, only a small amount is evaporated from the skin, without accumulation. It only takes 30 to 40 seconds to produce analgesic effect after inhalation. The analgesic effect is strong but the anesthetic effect is weak. The patient is in a conscious state (not an anesthetic state), which avoids complications of general anesthesia and recovers quickly after surgery.
