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.
尽管周围神经阻滞被认为非常安全，但对于许多可能特别适合应用这种麻醉技术的患者来说，他们可能已有周围神经病变，这使他们面临进一步神经损伤的风险。我们报告一例74岁男性患者，该患者有多种周围神经病变的危险因素，在接受罗哌卡因腘窝坐骨神经阻滞后出现足下垂。我们认为，罗哌卡因的血管收缩特性可能导致了已存在的神经元缺血，从而进一步损害了本已受损的神经。
