Summary

Technical issues with microspinal catheters for continuous spinal anaesthesia (CSA) can occur. This report details two rare complications: catheter elongation from stylet breakage and extracorporeal tearing leading to anesthetic leakage and failed procedures.

Area of Science:

  • Anesthesiology
  • Medical Devices
  • Neurosurgery

Background:

  • Continuous spinal anaesthesia (CSA) is a technique used for prolonged surgical anaesthesia.
  • Microspinal catheters, particularly 32-gauge catheters, are employed for CSA.
  • Technical problems associated with these catheters are documented but uncommon.

Observation:

  • This case report presents two unusual technical complications encountered during CSA using 32-gauge microspinal catheters.
  • The first complication involved extraordinary catheter elongation due to an embedded stylet fracture.
  • The second complication was a tear in the external portion of the catheter, causing local anesthetic leakage.

Findings:

  • Catheter elongation resulting from internal stylet breakage is a rare occurrence in CSA.

Related Experiment Videos

  • Extracorporeal catheter tears can lead to significant local anesthetic leakage.
  • These complications can result in the failure of spinal anaesthesia, necessitating alternative management strategies.

    • Implications:

    • Awareness of these rare complications is crucial for anesthesiologists performing CSA.
    • Proper catheter handling and monitoring are essential to prevent such technical failures.
    • Understanding these issues can guide improvements in catheter design and procedural techniques for enhanced patient safety.
