The National Institute for Health and Clinical Excellence (NICE) has issued full guidance to the NHS in England, Wales, Scotland and Northern Ireland on Bronchial thermoplasty for severe asthma.


Asthma is a condition that causes the airways to become narrower; the lining of the airways also becomes inflamed and starts to swell. Bronchial thermoplasty involves applying thermal energy to the airway wall. The aim is to reduce the amount of excessive muscle in the airway, and limit its ability to contract and narrow the airway, in patients with severe asthma.
