Which of the following are the three classifications of anesthesia?

The classification of anesthesia includes General, Regional, and Monitored Anesthesia Care.

General anesthesia involves a complete loss of consciousness and sensation throughout the entire body, which is typically achieved through inhaled gases or intravenous agents. Patients undergoing procedures under general anesthesia do not respond to stimuli and are completely unconscious, making it suitable for major surgeries.

Regional anesthesia involves the administration of anesthetic to block sensation in specific areas of the body, such as limbs or sections of the abdomen. This method allows for pain control during and after surgical procedures without affecting the entire body’s consciousness.

Monitored Anesthesia Care (MAC) refers to a specialized anesthesia service that provides sedation and analgesia while enabling the patient to maintain their ability to respond to verbal commands. This type of anesthesia is often used for less invasive procedures and allows for a gradual transition between sedation levels based on patient needs.

The other options mix classifications that are either not recognized as standard anesthesia categories or represent specific techniques rather than broad categories. For example, spinal anesthesia is a type of regional anesthesia, and local anesthesia is typically less encompassing than the regional category, which covers various approaches, including epidurals, nerve blocks, and others. This precision in classification helps in understanding the different techniques and their appropriate applications in surgical
