Before the biopsy is performed, it is important to thoroughly evaluate the patient for-
- Concomitant medication / illness
- 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 individualís 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.
