Summary

Post-anesthetic lameness occurred in 6.4% of 733 horse anesthetic episodes. Hypotension and anesthetic duration were the only significant contributing factors identified in this study.

Area of Science:

  • Veterinary Anesthesiology
  • Equine Surgery
  • Animal Orthopedics

Background:

  • Post-anesthetic lameness is a common complication in horses.
  • Numerous factors have been implicated, but their statistical significance is often unclear.
  • Understanding risk factors is crucial for improving equine welfare and surgical outcomes.

Purpose of the Study:

  • To determine the incidence of post-anesthetic lameness in horses.
  • To statistically evaluate nineteen previously reported or proposed risk factors for post-anesthetic lameness.
  • To identify significant predictors of post-anesthetic lameness in equine patients.

Main Methods:

  • A retrospective study of 733 anesthetic episodes in 655 horses over three years.
  • Statistical analysis of nineteen potential risk factors, including hypotension and anesthetic duration.

  • Calculation of the incidence of post-anesthetic lameness.

    • Main Results:

    • The overall incidence of post-anesthetic lameness was 6.4%.
    • Statistical evaluation revealed that only hypotension and the duration of the anesthetic period were significant factors.
    • Other previously suggested factors did not show statistical significance in this cohort.

    Conclusions:

    • Hypotension and prolonged anesthetic duration are key risk factors for post-anesthetic lameness in horses.
    • Targeting these specific factors may help reduce the incidence of lameness post-anesthesia.
    • Further research could explore preventative strategies focused on maintaining blood pressure and minimizing anesthetic time.
