Patient Preparation

Anesthesia

Local anesthesia with 1% or 2% lidocaine is used. Some anxious patients may require a small oral or intravenous dose of a benzodiazepine (eg, lorazepam). In rare cases, consideration may be given for the use of procedural sedation (eg, midazolam and fentanyl). Overnight fasting by the patient is usually required prior to the procedure.

Positioning

The patient should be supine, with his or her right side near the edge of the bed. The patient’s right arm should be above the head. The feet should be angled across the bed to expand the intercostal space as much as possible. Adjust the height of the bed for comfort; the optimal position is  usually at or slightly below the level of the operator's elbows.
