Types of General Anesthetic Drugs || Classification of General Anesthetic Drugs #shorts #pharmacology #medicine • General anesthetics are a class of drugs used to induce a reversible state of unconsciousness and insensitivity to pain during surgical procedures. They are typically classified into two main categories: inhalation anesthetics and intravenous anesthetics. • Inhalation Anesthetics: These are volatile gases or vapors that patients inhale to achieve general anesthesia. Common examples include: • Nitrous Oxide: Often used in combination with other anesthetics for minor procedures. • Desflurane, Sevoflurane, Isoflurane: These volatile agents are used for maintaining anesthesia during surgery. • Intravenous Anesthetics: These drugs are administered through intravenous injections and are further categorized into induction agents and maintenance agents. • Induction Agents: These medications rapidly induce unconsciousness. Examples include propofol, etomidate, and barbiturates like thiopental. • Maintenance Agents: These drugs are used to sustain the anesthetic state after induction. Common options include opioids (e.g., fentanyl), benzodiazepines (e.g., midazolam), and ketamine. • General anesthetics work by depressing the central nervous system, causing a loss of consciousness, analgesia (pain relief), muscle relaxation, and amnesia. The choice of anesthetic and its administration depends on the patient's medical history, the type and duration of the surgery, and the preferences of the anesthesia team. • It's essential to use these drugs with caution, as they can have side effects and risks, including respiratory depression, cardiovascular effects, and postoperative nausea and vomiting. Anesthesia professionals carefully tailor the choice and administration of general anesthetics to ensure the patient's safety and comfort during surgery.
