Are anesthetics as safe as we think they are?
The majority of people reading this sentence will, at some point in their lives, undergo a medical treatment that requires general anesthesia. Doctors will inject them with a drug, or have them breathe it in. For several hours, they will be unconscious. And almost all of them will wake up happy and healthy.
We know that the general anesthetics we use today are safe. But we know that because they’ve proven themselves to be safe, not because we understand the mechanisms behind how they work. The truth is, at that level, anesthetics are a big, fat question mark. And that leaves room for a lot of unknowns. What if, in the long term, our anesthetics aren’t as safe for everyone as we think they are?
