Minor vascular trauma during spinal anesthesia is common, particularly when patients experience paresthesia or if multiple needle passes are needed. This can be detected by red blood cell counts in cerebrospinal fluid samples.

Area of Science:

  • Anesthesiology
  • Neurosurgery
  • Neurology

Background:

  • Spinal anesthesia involves subarachnoid puncture, which carries a risk of vascular trauma.
  • Assessing the extent and predictors of vascular trauma is crucial for patient safety.

Purpose of the Study:

  • To quantify vascular trauma during spinal anesthesia.
  • To identify factors associated with increased vascular trauma, such as paresthesia and needle manipulation.

Main Methods:

  • Cerebrospinal fluid samples from 130 patients undergoing spinal anesthesia were analyzed for red blood cell counts.
  • Two samples per patient were collected; the second sample's RBC count served as the primary measure.
  • Correlation analysis was performed to assess the impact of needle type, number of passes, and paresthesia.

Main Results:

  • Red blood cells were detected in 38% of samples, with 14% showing counts over 100 cells/mm³.
  • Paresthesia was reported by 8.5% of patients and strongly correlated with elevated RBC counts (p < 0.0001).
  • Increased needle passes also significantly correlated with higher RBC counts (p < 0.0001); needle type and antiplatelet therapy did not show significant influence.

Conclusions:

  • Routine spinal anesthesia frequently involves minor vascular trauma.
  • Paresthesia and technical difficulties (multiple needle passes) are key indicators of increased vascular trauma.
  • Monitoring RBCs in CSF can help assess procedural trauma during spinal anesthesia.
