1. What is General Intravenous Anesthesia?
Intravenous Anesthesia is a way of general anesthesia of the patient through the use of anesthetics, sleeping pills or sedatives injected through a vein or muscle. Intravenous anesthesia produces clinically reversible anesthesia, with the patient's breath free of anesthetic vapors.
Intravenous anesthesia includes anesthesia alone using only one type of anesthetic and combined anesthesia ie using a combination of anesthetic and analgesic or two types of anesthetic together.
Intravenous anesthesia includes methods such as ANS, APP, ketamine or propofol alone, TIVA. In which, TIVA mode, also known as total intravenous anesthesia, is the most complete anesthetic method, which synthesizes most of the advantages of the above methods as well as further studies on pharmacokinetics, this is also the most complete method of anesthesia. The most commonly used method in clinical practice today.
The ideal requirements of intravenous anesthetics include rapid induction of anesthesia, no associated adverse effects, especially for the respiratory and circulatory systems, strong analgesic effects, rapid recovery after discontinuation, and minimal anaesthesia. uncomfortable for the patient, does not release histamine, reduces intracranial pressure, does not irritate the surrounding tissues, dissolves and can be kept for a long time after mixing. However, in practice, there is currently no intravenous anesthetic that meets all of the above requirements. Therefore, intravenous general anesthesia is preferred for most indications of anesthesia.

General advantages of general intravenous anesthetic include:
Medical staff when performing anesthesia for patients do not have to inhale toxic anesthetic gases; There is no need to use many devices, means or support tools like other anesthetic methods, which also minimizes the risk of fire and explosion; Do not pollute the environment ; Advantages of each type of general intravenous anesthetic:
