A Prospective Comparison of Pain and Analgesia in Patients With Continuous Peripheral Nerve Block Catheters Using Continuous Infusion or Scheduled Bolus Infusion
Stanford University
Summary
The goal of the study is to compare continuous infusions and scheduled bolus infusions for peripheral nerve blocks and their effect 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 increasi…
