Figure 1

Results from photoplethysmography (PPG) studies obtained throughout the patient’s hospitalizations. Of particular interest is the sustained blood flow seen in the 4th and 5th digits one week after her liposomal bupivacaine (Exparel) block. The 1st digit was nonischemic and included as a control.
