The difference between respiratory anesthesia and injection anesthesia

Respiratory anesthesia, that is, inhalation anesthesia, enters the alveoli through breathing and then enters the blood. The drug concentration in the blood and the inhaled concentration will reach a balance so that the anesthesia can be maintained. After the operation, the inhalation is stopped, and the drugs in the blood are exhaled out of the body through the alveoli. There is basically no need for metabolism in the body, so the drugs will be cleared faster.
Injection anesthesia, that is, intravenous or intramuscular anesthesia. Injected anesthetics must be metabolized by the liver and kidneys before they can be cleared from the body. This time will be relatively long and may have certain side effects on the liver and kidneys.

From the perspective of recovery time, the recovery time from respiratory anesthesia is very short. As long as the air supply is stopped, the animal can wake up in a short time. However, Shutai will usually wake up half an hour to 1 hour after the operation. . In my opinion, the faster the recovery, the better, because it is not a good thing for animals to quickly recover pain after surgery. Shutai’s recovery time after surgery is acceptable.

From the perspective of causing allergies, there is no essential difference between respiratory anesthesia and (Sulta) injection anesthesia.

From the perspective of liver and kidney burden, respiratory anesthesia is better, but the metabolism of Serta is also very small. There are no reports in the world that Serta causes metabolic abnormalities and liver and kidney poisoning in cats. .
There is therefore no essential difference in safety between injection anesthesia and respiratory anesthesia. However, for cats with liver and kidney dysfunction (such as cats with renal failure), it is better to choose respiratory anesthesia if surgery is necessary.
Another advantage of respiratory anesthesia is that it provides oxygen during anesthesia to ensure the body's oxygenation status. This aspect can reduce the risk of anesthesia.

Injection anesthesia

1. Domestic anesthetics
Generally refers to the 846 mixture. Usually the sedation can last for 1-2 hours, and the analgesic effect can only last for 15- 30 points. Propofol: A very new anesthetic, an ideal short-acting intravenous anesthetic, with an average anesthetic time of about 3 minutes. This anesthetic can be used to safely induce anesthesia in elderly and frail animals. If continuous intravenous infusion is used, anesthesia can be maintained well. This anesthetic is metabolized by the liver and broken down rapidly. However, it can cause respiratory depression in individual animals. Use with caution in cases of liver disease.
Acetylpromazine: a preoperative sedative, very safe, and can have a very good sedative effect after injection, which can reduce the use of other anesthetics. Not for boxer anesthesia.

2. Imported anesthetics
There are many kinds. Of course, the common saying among cat lovers is the name Shutai. This is not a complete statement, but in today's In the pet medical industry, the imported anesthetic used in most cases is Shutai.
This kind of anesthetic has good anesthesia effect, low probability of allergies, and is also a member of Veterinarians Without Borders.An anesthetic that has been recommended since the introduction of sterilization and lateral incision technology in China. In the early days, cats were prone to shaking their heads and trembling after waking up due to the sole use of Serta. Later, auxiliary methods such as injecting sedatives before anesthesia were used, and these phenomena have been greatly reduced.
It can therefore be considered that Serta is a very safe anesthetic.

Breathing Anesthesia < /h2> Inhaling Anesthesia is a process of using the respiratory tract inhalation of gas anesthetics. Inhalational anesthesia is an anesthetic commonly used in small animal clinical practice abroad.
With the development of domestic small animal industry, many domestic hospitals have also begun to use inhalational anesthetics. Inhalation anesthesia not only expands the clinical medical space for small animals. For example, the use of inhalation anesthesia can perform thoracotomy, lung tumor resection, cardiac surgery, thoracic esophageal surgery, diaphragmatic hernia repair surgery, etc. In addition, it can also be used for critically ill and elderly patients. Anesthesia for old and frail animals increases safety. Compared with other types of anesthesia, the only disadvantage of inhalation anesthesia is that it is more expensive and requires professionals to operate it. It can be said that inhalation anesthesia is the first choice for pet anesthesia.

The most important advantage of inhalation anesthesia is: safety
*Good anesthesia effect and strong analgesia
*Little adverse effects on the heart and lungs
*No effect on the liver and kidneys
*Keep the respiratory tract open and provide adequate nutrition
*No allergic reaction
*Quick recovery
*In case of emergency, it is convenient for rescue
