Anesthesia considerations for lung volume reduction surgery.

Abstract

Patient selection is of crucial importance for outcome after lung volume reduction surgery. The anesthesiologist should be involved actively in patient selection, because he or she is in charge of the treatment during the critical perioperative period. Patient history and status and results from chest radiographs, high-resolution CT scans, and catheterization of the right heart should be taken carefully into account in the patient selection process. Promising new results involving functional parameters may predict outcome objectively after lung volume reduction surgery in the future. Careful selection and preoperative preparation of patients also are important to avoid complications and keep the success rate high. The anesthesiologist's understanding of the principles involved is important for the successful conduct of lung volume reduction surgery. It is unclear if lung volume reduction surgery is superior to conventional therapy in the long run because the decline in lung function is progressive after the procedure. A multicenter trial comparing patients undergoing lung volume reduction surgery with patients with emphysema who are treated conventionally hopefully will clarify this important question in the future.
