How is 
the Patient Prepared for the Lung Biopsy Procedure?
  • Any drug allergy
  • Past history of bleeding / clotting problems
  • Pregnant status- Biopsy should not be performed in pregnant women
  • Any primary lung diseases (cor pulmonale)

Biopsy is contraindicated in a patient with bullae (enlarged alveoli associated with emphysema), cysts, severe hypoxia (insufficient concentration of oxygen in blood) or pulmonary hypertension.

Tests commonly done before a biopsy procedure are:

  • Routine blood investigations
  • Platelet count is commonly done to check if the individual’s bleeding and clotting parameters are within normal limits. For those with counts lower than 50,000/cubic mm, a platelet transfusion would be required before the biopsy.
  • Chest X-ray - To locate the exact biopsy site
  • An arterial blood gas and a pulmonary function test may also be done.

Patient preparation before the biopsy-

  • The patient is asked to avoid aspirin, nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen, or blood thinners such as warfarin for a week before the procedure.
  • Patient consent for the procedure is obtained.
  • The patient should be on nil oral for a period of 12 hours before the biopsy.
  • Sometimes, medications may be prescribed to dry up secretions in the mouth and airways.
  • The patient is asked not cough during the biopsy procedure.
  • The patient may be intubated to allow proper breathing during the biopsy procedure.
  • Local anesthesia is injected into the site of the biopsy.
  • The patient is asked to sit in a relaxed position with arms resting forward on a table. The biopsy is performed using a suitable procedure. Pressure is placed over the site after the biopsy procedure. A chest x-ray is taken after the biopsy. The results are obtained after a few days.
