Area of Science:

  • Anesthesiology
  • Regional Anesthesia
  • Neurosurgery

Background:

  • Psoas compartment block (PCB) is utilized for hip surgery analgesia.
  • Spinal anesthesia is a common anesthetic technique for hip arthroplasty.
  • Concurrent use of PCB and spinal anesthesia requires careful consideration of potential interactions.

Observation:

  • A 70-year-old male undergoing hip arthroplasty received a PCB followed by spinal anesthesia.
  • Despite demonstrating free fluid flow, spinal anesthesia failed, necessitating general anesthesia.
  • The patient recovered with a functional PCB and no residual neuraxial blockade.

Findings:

  • This case presents a rare instance of failed spinal anesthesia after a successful PCB.
  • Hypothesized epidural spread of local anesthetic from the PCB may have mimicked correct spinal needle placement.

  • The presence of local anesthetic in the epidural space could lead to a false sense of security regarding intrathecal placement.

    • Implications:

    • Highlights the importance of recognizing potential complications when combining regional anesthetic techniques.
    • Suggests a need for vigilance in confirming true intrathecal placement, even with apparent indicators.
    • Underscores the critical role of differential blockade assessment in clinical anesthesia practice.
