To the Editor: Tonti-Filippini condemns denial of elective surgery to smokers as discriminatory.1 He disregards the fact that surgery requires anaesthesia, which may require serious consideration before undertaking non-urgent surgery, and in no way involves discrimination.

He mistakenly regards denying elective surgery to those who continue to smoke as discrimination, in breach of the Hippocratic Oath, and the Australian Medical Association (AMA) Code of Ethics. In fact, to proceed with elective, especially cosmetic, surgery in a heavy smoker is more in breach of the Oath and the AMA Code than not proceeding, for the following reasons.

Smokers are at a significantly greater risk under anaesthesia than non-smokers because, firstly, smoking reduces the capacity of the lungs to take up oxygen, thus increasing the risk of hypoxia and its consequences to heart and brain.2 It also causes coughing and breath-holding during anaesthesia,2,3 creating surgical difficulties, and the risk of error.

Postoperative coughing causes additional pain (especially after thoracic and abdominal operations), and increases the risk of postoperative bleeding, infection, delayed healing and even wound breakdown.4,5

Rather than being discriminatory, delaying elective and cosmetic surgery until he or she stops smoking is very much in the patient’s interests.
