Basic concepts of Anesthesia

Anesthesia involves the use of drugs to prevent pain during surgery or other medical procedures. These drugs can induce varying levels of sedation, from mild relaxation to complete unconsciousness. Administered through inhalation, injection, or intravenous methods, anesthesia works by temporarily blocking nerve signals in the brain and body.

This allows doctors to perform invasive procedures without causing discomfort to the patient. Anesthesia is carefully monitored by anesthesiologists to ensure patient safety and to adjust levels as needed. Its development has revolutionized medicine, enabling complex surgeries that were previously impossible due to the pain and risks involved.
