A needle is guided into the mass during bronchoscopy, and cells are dislodged with a sawing motion. Suction is applied to gather specimens. TBNA is typically used to determine whether the mass represents a malignancy, such as a bronchogenic carcinoma or lymphoma.
Why is TPN given before other feedings?
Sick or premature newborns may be given TPN before starting other feedings.
