What is intravenous anesthesia?

intravenous anesthesia involves injection of drugs directly into the bloodstream to achieve certain anesthetic goals, such as rendering the patient unconscious, reducing reflective reaction, soothing stress or other. This term is very often used to indicate general anesthesia, often required during surgery to promote the patient's complete unconsciousness. Such anesthesia is often administered using a well -controlled intravenous drop, in which drugs and other solutions such as liquid slowly drip into an intravenous catheter associated with the vein. Sometimes the only dose of intravenous anesthesia is given by injection directly into the vein and does not have to produce complete unconsciousness.

It is easy to compare intravenous anesthesia with other ways of providing different levels of sedation or pain control. A well -known alternative is anesthesia provided by an oral route that can be used in many environments. One difference between these two types is that any anesthetic directly injected into a vein is immediately in bloodThe riverbed, so it is faster and available in a larger offer.

A different form of anesthesia may be inhaled, usually faster than oral routes with greater biological availability because it reaches the bloodstream faster. Some people may have more than one type of anesthetics before surgery and could breathe some medicines, have intravenous or IV drip, which brings others and perhaps something orally before the procedure. If additional medicines are needed, the place of administration via drop IV may even be injected.

There are different goals of anesthesia and different types of drugs used in intravenous anesthesia. Among the objectives of anesthesia is to produce amnesia and unconsciousness, a boring reflective reaction (areflexia) and eliminate the feeling of pain. These three goals, when they are together, are called general intravenous anesthesia (TIVA). The fourth goal is often added.

to achieve tiva with růHe mixes medicines in an accurate way. Types of drugs used may include medicines such as benzodiazepines, barbiturates, opioids, analgesics such as non -steroidal anti -inflammatory drugs, a number of muscle relaxants and dissociative anesthetics such as ketamine or other anesthetics such as propofol. The exact combination of what people receive depends on how many parts of Tiva are for this procedure and also on human history, experience with anesthesia in the past and the preferences of anesthesiologists. The dosage also takes into account the size, age and other factors of the person.

In most cases, it is intravenous anesthesia by a highly individualized and selective process that depends on many elements. Patients can also choose about the types of anesthetics they would like to receive. Some procedures are performed with minimalnesthetics and others can use either sleeping or full general anesthesia. Doctors may ask patients to decide how much seating level they desire, usually knowing that if the level of sedation nSufficient, other anesthetics could be given. If intravenous anesthesia is already determined during the procedure, it is usually easy to add more medicines to intravenous drop.
