Effectiveness of Perineural Clonidine as an Adjuvant With Ropivacaine for Popliteal Nerve Block in Patients Undergoing Foot and Ankle Surgery

Stopped early · Phase 1/Phase 2

Conditions studied: Pain

In brief

Nerve blocks are used to decrease the amount of pain you have after surgery. We are asking you to take part in a research study. This research study will test whether adding a medicine called clonidine to nerve blocks helps to improve them. Nerve blocks typically last less than a day after surgery. We are looking for ways to make them work better and last longer. Clonidine is approved for use as a blood pressure medicine. Its use in nerve blocks is investigational, but it may help nerve blocks to last longer. Adding clonidine to nerve blocks may also decrease the amount of pain medicine a person has after surgery. All people who enter this study will receive a nerve block with the normal medicine, but half of people will also have clonidine added to their nerve block. This study will enroll 60 participants from UAB hospitals.

You may qualify if…

• Patient undergoing foot or ankle surgery with popliteal nerve block planned for postoperative analgesia.
• Adult, 19 years of age and older.
• Subject classified as American Society of Anesthesiology (ASA) class 1, 2, or 3. The ASA defines these statuses as follows: 1-A normal healthy patient. 2-A patient with mild systemic disease. 3-A patient with severe systemic disease.

• Subject with a history of continuous opioid use for greater than one month prior to surgery.
• Pre-existing neurologic deficit in lower extremity (surgical site).
• Clinically significant coagulopathy (hemophilia, von Willebrand disease).
• Patients who fail to follow the UAB Department of Anesthesiology Algorithm for the Preoperative Management of an Angiotensin Converting Enzyme Inhibitor (ACEI) or an Angiotensin Receptor Blocker (ARB). A copy of the algorithm can be found in Appendix 1. -
