Summary

Spinal anesthesia levels are inconsistently reported. Applying classical neuroanatomic maps to clinical data revealed significant differences, highlighting the need for precise map referencing in spinal blockade documentation.

Area of Science:

  • Anesthesiology
  • Neuroanatomy
  • Spinal Cord Anatomy

Background:

  • Surgical analgesia levels during spinal anesthesia are often reported without clear reference to established neuroanatomic maps.
  • Classical spinal nerve maps, such as those by Keegan and Garrett and Foerster, exhibit variability and inconsistent reporting in medical literature.

Purpose of the Study:

  • To evaluate the discrepancies between classical neuroanatomic maps when applied to the same clinical data.
  • To determine the clinical significance of differences in spinal nerve map interpretation for documenting spinal blockade levels.

Main Methods:

  • Comparison of classical neuroanatomic maps (Keegan and Garrett, Foerster) using identical clinical data.
  • Analysis of the variability and interpretation differences between these maps.

Main Results:

  • Application of different classical maps to the same clinical data yielded a theoretically significant difference of two spinal segments.
  • Inconsistent reporting and interpretation of neuroanatomic maps contribute to ambiguity in defining spinal blockade levels.

Conclusions:

  • Clear reference to the specific segmental map used is essential when documenting the level of spinal blockade.
  • Standardized reporting of spinal anesthesia levels requires consistent application and clear citation of neuroanatomic maps.
