What's the safest type of anesthesia? (Photo)

Honestly I'm trying to figure out what Anesthesia is the safest I'm not scared going under the knife I'm more scared about waking back up. I have low iron & some times I have breathing problems but I don't have asthma at all. My mother has went under Anesthesia before & she woke up just fine. But she said since I'm allergic to a couple of things you never know. I'm really scared & I'm trying to get a fat transfer & I wanted to know which Anesthesia is the safest. Please all doctors let me know
