Abstract

This study shows that when providing ropivacaine analgesia via a popliteal sciatic perineural catheter after moderately painful foot or ankle surgery, a continuous infusion is required to maximize infusion benefits. Furthermore, the addition of patient-controlled bolus doses allows for a lower continuous basal rate and decreased local anesthetic consumption, extending the duration of infusion benefits in an ambulatory setting with a limited local anesthetic reservoir. A continuous popliteal sciatic nerve block (PSNB) with a perineural local anesthetic infusion has been shown to provide multiple benefits after moderately painful orthopedic procedures of the foot, including decreased pain, opioid use, and opioid-related adverse effects.
