DÄ internationalArchive5/2015Questionable Statement
LNSLNS

The authors state that the sensitivity of chest X-rays is so low that they should only be obtained when a pertinent diagnosis is clinically suspected. To support this statement reference is made to two publications.

In the 40-year-old publication it is stated that a chest x-ray is essentially not indicated in asymptomatic patients under 20 years of age; a PA x-ray is indicated in patients aged 20 to 39 years; a PA and lateral chest x-ray is required in patients older than 40 years (1). The second publication investigates to what extent a preoperative chest x-ray triggers further actions and whether postoperative complications occur more frequently when no preoperative radiograph was obtained (2). The authors arrive at the conclusion that it is not necessary to obtain a chest x-ray in patients under age 70 with no risk factors; no recommendation is made for older patients. Thus, both citations cannot be used to suggest that chest x-rays are not necessary. From the perspective of anesthesiology and with a focus on perioperative complications, it may be justified to question the benefit of chest radiographs. However, it is a questionable approach to only obtain an x-ray in relation to the planned intervention and not based on a holistic understanding of the patient. In addition, it is negligent to state that the sensitivity of x-rays to diagnose cardiopulmonary disease is low. A screening study on the early detection of lung cancer showed that in asymptomatic smokers with a history of at least 30 pack years, chest radiography detected lung cancer in 3.5% of cases (3). The incidental finding in a chest x-ray is the only chance to detect lung cancer in an early, operable stage.

Taken together, these data suggest that preoperative chest x-rays in suitable quality should be requested, at least in smokers.
