Topical anesthetic cream significantly reduced pain from sphenoidal electrode insertion in epilepsy patients. Discomfort was comparable to heparin lock insertion, suggesting a minimally invasive procedure.

Area of Science:

  • Neurology
  • Anesthesiology

Background:

  • Sphenoidal electrodes are essential for epilepsy diagnosis and monitoring.
  • Electrode insertion can cause significant patient discomfort and pain.

Purpose of the Study:

  • To evaluate the efficacy of a topical anesthetic cream in reducing pain during sphenoidal electrode insertion.
  • To compare the pain associated with sphenoidal electrode insertion to that of heparin lock insertion.

Main Methods:

  • Patients received a topical anesthetic cream (2.5% lidocaine, 2.5% prilocaine) before electrode placement.
  • Discomfort was rated using an analogue pain scale.
  • Pain from heparin lock insertion was used as a control comparison.

Main Results:

  • No significant difference in pain levels was found between sphenoidal electrode insertion with topical anesthesia and heparin lock insertion.

  • Topical anesthesia effectively minimized discomfort associated with sphenoidal electrode placement.

    • Conclusions:

    • Topical anesthetic cream makes sphenoidal electrode insertion minimally painful.
    • The procedure's discomfort is comparable to that of a standard heparin lock insertion, improving patient tolerance.
