Microcatheters expanded continuous spinal anesthesia use but led to technical issues and neurologic deficits. Consequently, these devices were recalled, and alternative techniques are now preferred by most anesthesiologists.

Area of Science:

  • Anesthesiology
  • Neurosurgery
  • Medical Devices

Background:

  • Continuous spinal anesthesia (CSA) was historically limited to high-risk patients.
  • Microcatheters broadened the application of CSA to a wider patient population.
  • This study examines Canadian anesthesiologists' experiences with microcatheters and practice shifts post-withdrawal.

Purpose of the Study:

  • To document Canadian anesthesiologists' experiences with microcatheter-guided CSA.
  • To understand practice changes following the withdrawal of microcatheters.
  • To assess the safety and efficacy of microcatheters in CSA.

Main Methods:

  • A survey of Canadian anesthesiologists with experience or interest in regional anesthesia.
  • Data collected via telephone or mail.

Main Results:

  • 25 out of 36 respondents had used microcatheters for CSA.
  • Technical difficulties, catheter breakage, and neurologic deficits were reported.
  • Microcatheters were recalled in Canada following FDA alerts due to safety concerns.

Conclusions:

  • Alternative techniques have replaced microcatheter-based CSA.
  • Few anesthesiologists advocate for the return of microcatheters.
  • Safety concerns led to the discontinuation of microcatheter use in CSA.
