Anesthetics commonly used in animal experiments are: volatile anesthetics, nonvolatile anesthetics, and traditional Chinese anesthetics.

1. Volatile anesthetic

Volatile anesthetics include ether, chloroform, and the like. Diethyl ether inhalation anesthesia is applicable to all kinds of animals. The difference between the anesthesia amount and the lethal amount is large, the safety degree is also large, the depth of animal anesthesia is easy to grasp, and the anesthesia is quicker to wake up. The disadvantage is that it has a large local stimulus effect, which can cause increased secretion of upper respiratory mucosal fluid, and then can affect breathing, blood pressure and heartbeat activity through nerve reflexes, and easily cause suffocation. Therefore, someone must take care when inhaled with ether in ether Too deep and the situation is happening.

2. Non-volatile anesthetic

There are many types of non-volatile anesthetics, including phenobarbital sodium, pentobarbital sodium, thiopental sodium and other barbituric derivatives, ethyl carbamate and chloral hydrate. These anesthetics are easy to use, can maintain a longer anesthesia time with one administration, the anesthesia process is more balanced, and the animals have no obvious struggle. The disadvantage is that it is slower to wake up.
