What happens to your body during GENERAL ANESTHESIA?
Think of general anesthesia as a temporary, carefully controlled "super-sleep" managed by an anesthesiologist. Unlike regular sleep, your brain is switched off so completely that you don’t feel pain, hear anything, or form any memories during surgery.
Hear what happens to your body...
Your BRAIN goes to sleep.
Anesthetic pause the signals traveling between your brain cells. Within seconds, you drift into a deep unconsciousness. You do not dream or realize time is passing. Your brain completely stops registering pain signals.
Your BREATHING is guided.
Because your brain is in such a deep sleep, your body forgets to breathe deeply on its own, and your natural reflexes (like coughing or swallowing) temporarily stop. A breathing tube or mask is gently placed to deliver oxygen. A machine (a ventilator) breathes steadily for you throughout the procedure.
Your BLOOD PRESSURE and HEART RATE slow down.
Anesthesia relaxes your blood vessels and muscles, which naturally causes your blood pressure and heart rate to drop slightly. The anesthesiologisy constantly monitors your vital signs, your heartbeat, blood pressure, and oxygen levels, and adjusts medications to keep them in a safe, steady range.
Your MUSCLES relax.
Special medications are given to make your muscles completely limp. This stops any accidental twitching or movements and makes it safe and easy for the surgeon to operate.
Your TEMPERATURE drops slightly.
Anesthesia turns down your body’s internal thermostat, which can make you feel cold. To prevent this, warmed blankets or air-warming covers are used to keep you comfortable and warm.
When the surgery is finished, the anesthesiologist stops giving you the anesthetic. As it wears off, your brain slowly wakes up. Your body takes back control of your breathing and reflexes. You might feel groggy, chilly, or slightly confused for a short time, similar to waking up from a very deep nap.
