Most smokers are aware of the long term risks involved with tobacco use. Despite doctor’s warning against smoking before surgery, some patients continue to smoke before and after their surgery. Due to poor surgical outcomes and increased mortality and morbidity, some surgeons refuse to operate on smokers.
Continuing to smoke before and after surgery is equal to playing Russian roulette with your life. Patients who smoke during the last 24 hours before surgery have twenty times more episodes of inadequate oxygen supply to the heart while under general anesthesia than the non-smokers. This means that a smoker’s chanceof a heart attack due to smoking alone (not including smoking and medical history) is at least twenty times higher than in non-smokers.
As a smoker, or if you are exposed to second hand smoke, you can potentially develop complications such as poor wound healing, infection and bad scarring after surgery. Wounds will not heal without a good blood supply and circulating oxygen. Smoking reduces the blood flow to the wound by constricting small blood vessels; it reduces the ability of hemoglobin to move oxygen to the wound; and it reduces the amount of oxygen delivered to the wound.
