Anesthesiologia generalis, commonly referred to as general anesthesia, is a controlled state of unconsciousness induced by medications to render a patient insensible to pain during surgical or medical procedures. It is one of the most widely used forms of anesthesia, particularly for major surgeries, complex procedures, or when patients are unable to tolerate local or regional anesthesia. General anesthesia involves the administration of drugs through intravenous (IV) or inhaled routes to achieve three primary effects: analgesia (pain relief), amnesia (loss of memory), and unconsciousness.

The process typically begins with the administration of an induction agent, such as propofol, thiopental, or etomidate, which rapidly induces unconsciousness. Muscle relaxants, such as succinylcholine or rocuronium, may also be administered to facilitate intubation and ensure a clear airway. Once intubated, the patient is connected to a ventilator to maintain adequate oxygenation and ventilation. Maintenance of anesthesia is often achieved through a combination of inhaled anesthetics (e.g., sevoflurane, desflurane, or isoflurane) and IV medications (e.g., opioids, benzodiazepines, or ketamine).

Monitoring is critical during general anesthesia to ensure patient safety. Vital signs, including heart rate, blood pressure, oxygen saturation, and end-tidal carbon dioxide levels, are continuously tracked. Additional monitoring may include electrocardiogram (ECG), capnography, and neuromuscular monitoring to assess the depth of anesthesia and the effects of muscle relaxants. Complications, such as hypotension, hypoxia, or awareness during surgery (a rare but serious condition where the patient recalls events despite being anesthetized), are closely managed by anesthesiologists.

Recovery from general anesthesia occurs in a post-anesthesia care unit (PACU), where patients are closely observed until they regain consciousness and stable vital signs. The duration of recovery varies depending on the type and duration of anesthesia, as well as individual patient factors. General anesthesia remains a cornerstone of modern surgical care, enabling safe and effective interventions for a wide range of medical conditions.
