I understand patients are given gas to knock them out. But are they in any danger of being permanently harmed or even killed while asleep during the operation? Should I be worried about my friend who wants to change sex?
Being killed? Or dying of a complication? The way you wrote that, it seemed like your worry is the surgical team might murder a patient. Gender reassignment is major surgery, as is breast surgery, facial reconstruction, etc, and carry the risks of surgery complications, infections, anesthesia mistakes....
I worry that my friend might wake up during the operation and experience a lot of pain. He doesn't even like injections. How long does the gas keep them asleep for?
If your friend is a transsexual then any amount of worry you feel for him isn't going to change his desire to have gender reassignment surgery. It is very invasive and takes about a year to totally heal. The pain is significant for a few days following surgery but it can be managed with pills or injections. just before surgery the patient is usually given a spinal anesthesia. This will numb the area so that no pain is felt and no movement is possible. The patient is usually given a sedative to help them relax and/or sleep while the procedure is taking place. Look at this site to research spinal anesthesia: http://www.nlm.nih.gov/medlineplus/ency/article/007413.htm Check out the websites of some of the surgeons that perform this type of surgery and do some research. Then I'm sure you'll feel better about the surgery and any possible risks.
Anesthesiology is a branch of medical science. Waking during surgery is extremely rare after 1950. Your friend will have an anesthesiologist assigned for the duration of the surgery. One person totally focused on keeping the patient asleep and free of pain and awareness.
All Operations Carry A Degree Of Risk, Even The Most Simple Ones Like Lancing A Boil Or Removing An Ingrown Toenail. Once You Break The Skin Any Infection Can Enter The Body Through The Wound. Modern Medicine Is So Advanced Nowdays I'm Sure Your Worries Are For The Best Part Unfounded. I Wish Your Friend Well And Please Call Back Here And Tell Us How Everything Went.... Cheers Glen.
