Inhalation general anaesthetic refers to the administration of anesthetic drugs through inhalation to induce a state of unconsciousness, thus allowing medical procedures to be performed without pain or discomfort. It works by delivering anesthetic gases or vapors to the patient's lungs, where they are absorbed into the bloodstream and eventually reach the brain.
These anesthetic agents are inhaled by the patient through a mask, endotracheal tube, or other devices specifically designed for this purpose. Commonly used inhalation general anesthetics include sevoflurane, desflurane, isoflurane, and nitrous oxide. They are known for their fast-acting characteristics and ability to quickly induce anesthesia, making them suitable for both short and longer procedures.
Once the anesthetic agents are inhaled, they travel through the bloodstream to the central nervous system, where they depress the activity of the brain, causing loss of consciousness and preventing the perception of pain. Inhalation general anesthetics are also responsible for controlling other vital functions such as heart rate, blood pressure, and breathing during surgery.
Throughout the procedure, a trained anesthesiologist or anesthetist closely monitors the patient's vital signs and adjusts the levels of anesthesia as needed. The dosage and choice of inhalation general anesthetic depend on various factors such as the patient's age, medical history, and the type of surgery being performed.
In summary, inhalation general anesthesia is a method of administering anesthetic agents through inhalation, allowing an individual to be unconscious and pain-free during medical procedures. It is a critical component of modern surgical practices, ensuring patient comfort and safety.
