At present, there are two kinds of anesthesia used in domestic pet hospitals or clinics, one is non inhalation anesthesia, the other is inhalation anesthesia. There are many kinds of anesthetics, but there are only a few commonly used ones. When the owner takes the pet area for surgery, he often faces the choice of anesthesia, including domestic anesthesia, imported anesthesia and inhalation anesthesia.
In fact, there are many varieties of domestic anesthetics, but we often say “domestic anesthetic refers to” refers to a compound drug called 846 mixture. The imported anesthetics generally use zoletil. Of course, if it is fast, the male cat can be sterilized with propofol sometimes. Isoflurane (ether) and enflurane (ether) are mainly used for inhalation anesthesia. Sevoflurane and desflurane are safer. However, because they are too expensive and the former has high safety, isoflurane (ether) and enflurane (ether) are mainly used.
846 mixture, also known as Sumianxin injection, is a compound preparation of JINGSONGLING, EDTA, DIHYDROETORPHINE HYDROCHLORIDE and haloperidol. It has been used for a long time in China and has been used up to now. When it is combined with ketamine in a certain proportion, it can not only shorten the anesthesia time, but also improve the safety. However, ketamine is now controlled by the state and is difficult to buy. The drug is cheap, anesthesia time is long, muscle relaxation and sedation effect are very good during anesthesia, but because of slow metabolism, it has a strong inhibitory effect on heartbeat and respiration, and there is a risk of pulmonary edema after anesthesia, which is more likely to cause anesthesia accidents and cause death. Especially for the elderly animals, poor physique of animals anesthesia risk is great! So many large hospitals are not recommended to use.
Shutai, that is, we often say imported anesthetic. It is a new type of separation anesthetic. Its components contain the sedative tiletamine and the muscle relaxant zolazepam. Its effect is equivalent to ketamine + diazepam. In general anesthesia, it has the advantages of short induction time, minimal side effects and good safety. When injected intramuscularly or intravenously, it has good local tolerance and is a very safe anesthetic. However, due to the limited anesthesia time, it is usually about 20 to 30 minutes, and only a few small operations can be done. However, for some operations that require relatively long time, 846 is usually mixed in Shutai to prolong the operation time.
Inhalation anesthesia refers to the anesthetic gas into the respiratory tract, and through the alveoli into the blood, and then to the brain to achieve the effect of anesthesia. Compared with the injection anesthesia, the anesthetic must be metabolized through the liver and kidney. Inhalation anesthesia is mainly excreted through the breath of the lung, which causes less damage to the liver and kidney. Moreover, the depth of anesthesia can be controlled, the time can be controlled, the effect is good, and the recovery is fast. At the same time, it also ensures the normal of respiratory tract. In the way of inhalation anesthesia, thoracotomy can also be carried out, which can not be completed in the case of injection anesthesia. It also reduces the risk of anesthesia for old and weak animals. Both isoflurane (ether) and enflurane (ether) for anesthesia are safe.
At present, with the development of the pet market, the improvement of veterinary technology and the improvement of pet owners’ literacy, the view on surgery was not given anesthetics decades ago, but domestic anesthetics, imported anesthetics and even inhalation anesthesia were used. This is a long and gradual process. With the close relationship between pets and their owners, for the health of pets, domestic anesthetics will be gradually eliminated, and inhalation anesthesia will be gradually popularized.
