Dr. Kim’s awake facelift focuses on minimizing risks and providing patients a safer means to achieve their goals
General anesthesia carries some well-known risks, such as blood clots that can traverse into the lungs, also known as pulmonary embolism, which can be life-threatening. Another risk is thrombosis (clot in the heart) that leads to myocardial infarction (heart attack). Another risk is a blood clot in the brain, also known as a stroke, that can cause abnormal brain and body function. A study published in Lancet evaluated patients 65+ years of age. It involved 12 academic medical centers in 9 countries and showed that 7% of patients experienced covert stroke (acute brain infarct), detected by brain MRI, following general anesthesia intubation.
One study revealed that 75% of complications that required a transfer to the hospital during a cosmetic procedure occurred under general anesthesia.
Knowing the risks and complications of general anesthesia, patients may opt for IV sedation, also known as twilight sedation. While general anesthesia puts one to sleep by delivering anesthetic gas through a breathing tube from your mouth to your lungs which then travels to the brain, intravenous (IV) sedation involves administering anesthetic through the veins which then travels to your brain. Therefore, both methods involve anesthesia affecting the brain by altering and stopping the brain function. Patients may view IV sedation as being safer than general anesthesia as it does not require intubation. However, IV sedation carries a high risk of respiratory distress as one does not oxygenate properly. This occurs because intravenous sedation depresses the respiratory center of the brain, similar to how a drug overdose can cause someone to stop breathing. An example of this is Joan Rivers, who experienced fatal hypoxia from IV sedation.
Both general anesthesia and IV sedation act on the brain to put patients to ‘sleep.’ However, this is not a natural state of sleep. During natural sleep or rest, a person will wake up in response to a loud noise or physical stimulation. However, under anesthesia-induced sleep, even painful stimuli from surgery (e.g., cutting and dissecting) will not awaken the patient. This forced shutdown of the brain has negative ramifications. It causes permanent neuronal (brain) damage that affects short-term memory and increases the chances of developing dementia.
Younger patients who have had surgery with general anesthesia or IV sedation may not feel the effects of memory loss or cognitive dysfunction after their procedures. However, research has shown that even a single exposure to general anesthesia or IV sedation for 1.5 hours significantly increases the chance of developing dementia, compared to local anesthesia. This means that even if you do not experience noticeable cognitive decline after surgery, it does not mean that you are safe from long-term harm of receiving general anesthesia or twilight sedation.
