Local Anesthetics: Clinical Application as Spinal Anesthesia

1.3K
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...

Area of Science:

  • Spine biomechanics and regenerative medicine.
  • Orthobiologics and pain management.

Background:

  • Low back pain (LBP) is a complex condition with multifactorial origins.
  • Traditional treatments often target single pain generators, overlooking the interconnectedness of spinal structures.

Purpose of the Study:

  • To review the concept of the functional spinal unit (FSU).
  • To evaluate orthobiologics like platelet-rich plasma (PRP) and mesenchymal stem cells (MSCs) for treating back pain.

Main Methods:

  • A narrative literature review was conducted.
  • Searches included PubMed, Embase, and Google Scholar for studies on FSU anatomy, biomechanics, pathology, and orthobiologic applications in spinal disorders.

Main Results:

  • The FSU, comprising vertebrae, IVD, facet joints, and ligaments, is key to spinal function.
  • Orthobiologics (PRP, MSCs) show potential in tissue repair and pain reduction by targeting multiple FSU components.
  • Chronic LBP often involves multiple pain generators, necessitating an integrated FSU-focused treatment approach.

Conclusions:

  • Orthobiologic treatments offer a disease-modifying strategy by addressing the entire FSU.
  • Further research is needed to optimize multitarget injection strategies and standardize protocols for LBP management.
