Patch Clamp01:18

Patch Clamp

Many fundamental cell functions such as muscle contraction and nerve transmission rely on the electrical signals produced by the movement of positively and negatively charged ions across the cell membrane. One competent method to record current flowing across the whole cell or single ion channel is the patch-clamp technique.
In this method, a glass micropipette containing electrolyte solution is tightly sealed against a small portion of the cell membrane. As a result, a patch of the cell...

Area of Science:

  • Neurosurgery
  • Surgical Instrumentation
  • Biomedical Engineering

Background:

  • The Mayfield head clamp (MHC) is a standard device for head and neck immobilization during neurosurgical procedures.
  • Reliance on the MHC is high, assuming its inherent safety and reliability in clinical settings.
  • Degenerative spondylotic cervical stenosis is a common condition requiring surgical intervention like cervical laminoplasty.

Observation:

  • An extremely rare incident of MHC system breakage occurred during the installation phase for a cervical laminoplasty.
  • The breakage happened when force was applied during pin fixation, despite the patient being stable.
  • No head or neck injury was sustained by the patient due to the incident.

Findings:

  • The Mayfield head clamp arm fractured during an attempted installation for cervical laminoplasty.
  • Despite the instrument failure, the patient remained stable, and the surgery was successfully completed using an alternative MHC.
  • The patient experienced no complications related to the MHC system post-surgery.

Implications:

  • Highlights the critical importance of rigorous instrument management and maintenance protocols for neurosurgical equipment.
  • Suggests a need for further investigation into the mechanical integrity and failure modes of the Mayfield head clamp under stress.
  • Emphasizes that even rare equipment failures necessitate robust contingency planning in surgical procedures to ensure patient safety.
