PRIMARY OBJECTIVE:

I. To compare Global chest pain score (measured on the Visual Analog Scale [VAS] scale) post-procedure and post procedural chest pain (measured on the numerical rating scale), at the time of discharge from recovery between liposomal bupivacaine (EXPAREL) and 1% lidocaine.

SECONDARY OBJECTIVES:

I. To compare post procedural chest pain (measured on the numerical rating scale) at the time of discharge from recovery, 24 hours and 48 hours post procedure between EXPAREL and 1% lidocaine.

II. To assess the change in global chest pain score (measured on the VAS scale) from baseline to the time of discharge from recovery, and post procedural chest pain (measured on the numerical rating scale) from baseline over time between EXPAREL and 1% lidocaine.

III. To compare the number of narcotics within 24 hours, and from 24 to 48 hours post procedure between EXPAREL and1% lidocaine.

OUTLINE: Patients are randomized to 1 of 2 groups.

GROUP A: Patients receive liposomal bupivacaine via injection into the intercostal nerve block.

GROUP B: Patients receive lidocaine via injection into the pleuroscopy port incision sites and indwelling pleural catheter site.
