Clinical Trial Summary

To compare continuous infusions to bolus infusions and there affect on post-surgical pain.

Description:

Regional anesthetic techniques are an integral part to many anesthetic approaches, providing both intraoperative and postoperative anesthesia and analgesia. Regional anesthesia peripheral nerve blocks have been shown to reduce postoperative pain and improve measures such as opioid requirements and readiness for discharge. By using a catheter technique for continuous peripheral nerve blocks, analgesia can be extended well into post-operative days 2 and 3, further extending these benefits. Historically these catheters have implemented a continuous dosing regimen of local anesthetic, but increasingly there is evidence of improved analgesic outcomes without adverse effects by using a scheduled bolus dosing regimen. Many institutions have implemented this new protocol for catheter dosing. The beneficial effect of scheduled bolus dosing has not been studied in all blocks and all surgical procedures.
