Inhalation agents are substances used in medicine to induce anesthesia during surgical procedures. These agents are typically gases or volatile liquids that, when inhaled, affect the central nervous system, leading to a loss of consciousness and sensation. Common examples include nitrous oxide and isoflurane, which are administered through a mask or breathing tube. These agents are carefully monitored by anesthesiologists to ensure patient safety and comfort. The dosage and type of inhalation agent used can vary based on the patient's needs and the type of surgery being performed. Proper management of these agents is crucial for effective anesthesia and recovery.
