Overview

Nitrous oxide, also known as laughing gas, is a colorless, sweet-smelling gas with the chemical formula N2O. It is an oxidizer. The application of nitrous oxide in clinical settings is very extensive because it is stable at room temperature, has mild anesthetic properties, and can cause laughter. Its anesthetic effect was discovered by the British chemist Humphry Davy in 1799.

Mechanism of action

N2O has been used in the field of anesthesia for over 160 years, and is clinically safe in inhalation anesthesia & sedatives. It is mixed with oxygen at a certain concentration ratio to form a subanesthetic gas that can have a good sedative effect. The laughing gas analgesia system provides patients with a moderate concentration of laughing gas and oxygen (laughing gas concentration no more than 70% and oxygen concentration) by inhibiting the release of excitatory neurotransmitters in the central nervous system and the conduction of nerve impulse and changing the permeability of ion channels.

Applied range

Applicable for pain relief in clinical childbirth, abortion, and oral fields.
