Yes, when you are "put to sleep" for a medical procedure, which is officially known as receiving general anaesthesia, a tube is typically placed into your throat. This crucial step is taken to ensure you can breathe properly and safely throughout the procedure.
Why is a Tube Inserted During General Anaesthesia?
General anaesthesia causes a state of controlled unconsciousness. While you are deeply asleep and feel no pain, the medications used can relax all the muscles in your body, including those that help you breathe. Without assistance, your natural breathing might become too shallow or even stop.
To prevent this and maintain a clear airway, an anaesthetist will:
- Insert a breathing tube: This tube, often an endotracheal tube or a laryngeal mask airway (LMA), is carefully placed into your windpipe (trachea) or over your voice box once you are fully unconscious. It connects to a machine that helps you breathe by delivering oxygen and anaesthetic gases.
- Assist ventilation: The breathing machine ensures that your lungs receive a steady supply of oxygen and that carbon dioxide is removed from your body. This controlled breathing is vital for your safety and well-being during surgery.
What Else Happens During General Anaesthesia?
While the breathing tube is a key component, general anaesthesia involves comprehensive monitoring and care to keep you safe. Healthcare professionals will continuously watch your vital signs:
- Heart Rate: Your pulse is monitored to ensure your heart is beating at a healthy rhythm and rate.
- Blood Pressure: Regular blood pressure readings help medical staff ensure proper blood circulation.
- Oxygen Levels: A sensor placed on your finger or earlobe measures the amount of oxygen in your blood.
- Fluid Administration: You will typically receive fluids, and sometimes medication, through a drip inserted into a vein, usually in your arm. This helps maintain hydration and supports your body's functions.
These measures, including the insertion of a breathing tube, are standard procedures designed to create a safe environment for you during surgery or other medical interventions. The tube is usually removed before you fully wake up, often while you are still in a twilight state, so you won't remember its removal.
