Foot Drop Following a Popliteal Sciatic Nerve Block with Ropivacaine, A Case Report and Literature Review

Abstract

Andreas Clipet-Jensen, Hans Fjeldsøe-Nielsen, Peter Roy Kirkegaard Department of Anesthesiology and Intensive Care Medicine, Zealand University Hospital, Nykøbing, DenmarkCorrespondence: Andreas Clipet-Jensen, Email [email protected]; [email protected]: Although peripheral nerve blocks are deemed very safe, a significant number of patients for whom this anesthetic technique may be particularly appealing to apply may present with preexisting peripheral neuropathies, putting them at risk for further nerve damage. We present a case with a 74-year-old male with several risk factors for peripheral neuropathy who developed a foot drop following a popliteal sciatic nerve block with ropivacaine. We suggest that the vasoconstrictive properties of ropivacaine may have contributed to a preexisting neuronal ischemia, thus further damaging an already compromised nerve.Keywords: peripheral nerve block, peripheral neuropathy, vasoconstriction, local anesthetics
