General anesthetic

General anesthetic is a type of anesthesia that induces a reversible loss of consciousness and sensation. It is used during surgical procedures to prevent pain and discomfort. The drugs used for general anesthesia are administered either through inhalation or intravenous injection.

Types of General Anesthetics

There are two main types of general anesthetics: Inhalational anesthetics and Intravenous anesthetics.

Inhalational Anesthetics

Inhalational anesthetics are gases or vapors that are inhaled and absorbed through the lungs. Examples include Nitrous Oxide, Desflurane, Sevoflurane, and Isoflurane.

Intravenous Anesthetics

Intravenous anesthetics are drugs that are administered into a vein. Examples include Propofol, Etomidate, Barbiturates, and Ketamine.

Effects of General Anesthetics

General anesthetics work by altering the activity of the central nervous system, leading to a loss of sensation and consciousness. They affect various body systems and can cause changes in heart rate, blood pressure, breathing, and body temperature.

Risks and Complications

While general anesthesia is generally safe, it does carry some risks. These can include nausea, vomiting, sore throat, confusion, and memory loss. In rare cases, serious complications such as allergic reactions, breathing problems, and heart attack can occur.

Preparation for General Anesthesia

Before undergoing general anesthesia, patients are usually asked to fast for a certain period of time. They may also need to stop taking certain medications.

Recovery from General Anesthesia

After the procedure, patients are monitored in a recovery room until the effects of the anesthesia wear off. They may experience grogginess, nausea, or coldness upon waking.
