Y48.1: Parenteral anaesthetics

Parenteral anaesthetics are medications that are administered through routes other than the digestive tract to produce a state of temporary loss of sensation or awareness. This is usually used during surgery or medical procedures. These medications may be delivered intravenously (into a vein), intramuscularly (into a muscle), or through other non-oral routes. They work by blocking the nerve signals to the brain, so that the patient does not feel pain and is not conscious of what is happening. The effects can range from localised numbness (as used in dental procedures) to full loss of consciousness (as used in major surgeries). Potential side effects may include slowed breathing, lowered blood pressure, and allergic reactions. A healthcare professional who is trained in anaesthesia will monitor the patient’s vital signs and adjust the medication as needed to ensure patient safety and comfort during the procedure.
