Insights

A patient experienced involuntary leg movements after epidural lidocaine injection for bladder tumor surgery. Further diagnostic imaging ruled out serious complications, though the exact cause remains unclear.

Area of Science:

  • Anesthesiology
  • Neurology

Background:

  • A 79-year-old male underwent transurethral resection of a bladder tumor.
  • Preoperative assessments showed no significant abnormalities.

Observation:

  • An epidural catheter was placed at the L3-4 interspace for anesthesia.
  • 1.5% lidocaine (10 ml) was administered without immediate adverse events.
  • Involuntary lower extremity movements began approximately 30 minutes post-injection.

Findings:

  • The involuntary movements persisted for 150 minutes without sensory or motor deficits.
  • Post-operative examination revealed no hemorrhage or pain at the puncture site.
  • Cerebral CT and lumbar MRI scans did not identify any abnormalities that could explain the movements.

Implications:

  • The precise mechanism of the observed involuntary movements remains undetermined.
  • Diagnostic imaging is crucial for excluding complications such as epidural hematoma.
  • This case highlights the importance of comprehensive evaluation for unexpected neurological events post-epidural anesthesia.

Local Anesthetics: Clinical Application as Epidural Anesthesia

Epidural anesthetics are administered in the fat-filled epidural space, the outermost part of the spinal canal. This technique is commonly employed for pain management and anesthesia during lower abdomen and pelvis surgeries or labor and delivery.
Since epidural anesthetics can be infused through an epidural catheter, all types of drugs, including short-acting ones, can be administered. Chloroprocaine and lidocaine are examples of short and long-duration anesthetics, respectively. Bupivacaine...

Local Anesthetics: Clinical Application as Spinal Anesthesia

Spinal anesthetics are given during lower abdomen and limb surgeries to block sensory and motor neurons. They are administered in the mid to low lumbar regions, primarily acting on the cauda equina's nerve roots. The blockade level depends on the local anesthetic (LA) concentration. Usually, low LA concentrations are sufficient to block sensory fibers, while only high LA concentrations block motor fibers. Other factors like injection volume and speed, the patient's posture, and the drug...

Herniated Intervertebral Disc l: Introduction

Intervertebral disc herniation refers to the displacement of the nucleus pulposus (the gel-like inner core of the disc) through a tear or weakened area in the annulus fibrosus (the outer fibrous ring). The displaced disc material extends beyond the normal boundaries of the disc space and may compress or irritate nearby spinal nerve roots or, less commonly, the spinal cord.Etiology and Risk FactorsHerniation commonly results from degeneration, in which aging reduces disc hydration and...

Local Anesthetics: Clinical Application as Intravenous Regional Anesthesia

Intravenous regional anesthesia or the Bier block technique is used to anesthetize a specific limb or extremity. It uses exsanguinated or blood-drained vessels to transport local anesthetics or LAs to the peripheral nerve trunks. Lidocaine without vasoconstrictors like epinephrine is most commonly used for this technique. Other drugs used are prilocaine, ropivacaine, and chloroprocaine. Bupivacaine is not recommended for this technique due to its high cardiac toxicity.
