Caudal epidural catheterization for pain management in 48 hospitalized horses: A descriptive study of demographics, complications, and outcomes.

Abstract: The placement of caudal epidural catheters in horses has become more frequent as a multi-modal analgesic strategy. Despite its integration into clinical practice, there are limited reports describing the use of caudal epidural catheterization for prolonged use in horses. The purpose of this study was to characterize the hospitalized caseload undergoing epidural catheterization for long-term epidural analgesic administration, to report the response to epidural therapy and observed complications, and to describe patient outcomes. Medical records of hospitalized equine patients that underwent placement of a caudal epidural catheter for analgesic management between 2017 and 2021 were analyzed retrospectively. For the 62 catheters placed in the 48 cases, the most frequent diagnosis category prompting epidural analgesia was orthopedic (43/48, 89.6%). Synovial sepsis was the most frequent specific diagnosis prompting epidural catheter placement (11/48, 22.9%). The initial response to epidural therapy was characterized as positive for 37/62 (59.7%) catheters. Complications were documented for 46/62 (74.2%) catheters. However, most of these complications were classified as mild (51.6%) or moderate (14.5%), and exaggerated physiologic responses were observed most frequently. Of the horses studied, 52.1% survived to be discharged from the hospital. With awareness of potential complications and vigilant monitoring, caudal epidural catheters should be considered for equine patients as an analgesic strategy.

This study analyzes the use and effects of caudal epidural catheterization as a method of pain management in hospitalized horses. The authors identified that despite certain complications, the strategy was largely successful in providing pain relief, and can be recommended with careful monitoring.

Research Context

  • The research looked into the use of caudal epidural catheterization in horses for long-term pain management. This technique involves positioning a tube (catheter) into the lower back part of the spinal cord (caudal epidural space) to deliver pain relief medication directly to nerves transmitting the pain signal.
  • This study was conducted due to limited literature on long-term use of this technique in horses, despite its increasing use clinically. The researchers aimed to assess the demographic characteristics of affected horses, report the complications encountered, evaluate the response to therapy, and present the outcomes of the patients.

Methodology and Findings

  • Medical records of horses that were hospitalized and underwent this procedure between 2017 and 2021 were evaluated.
  • In total, 62 catheters were placed in 48 different cases. The most common reason for using epidural analgesia was for orthopedic issues, with synovial sepsis, an infection in a horse’s joint or tendon sheath, being the most frequent specific diagnosis.
  • The initial response to the therapy was predominantly positive, with over half of the catheters (59.7%) resulting in some level of pain relief.
  • Regarding complications, there were recorded complications in about 74.2% of the catheters. However, these were mostly categorized as mild or moderate, with exaggerated physiological responses being the most commonly observed complication. An exaggerated physiological response implies any changes related to the body’s normal function such as heart rate or blood pressure that are beyond the typical ranges during pain management therapy.
  • In terms of patient outcomes, just over half (52.1%) of the horses under study survived and were able to be discharged from the hospital.

Conclusions

  • The study concludes that while complications do occur in a significant proportion of cases, most were mild or moderate in nature. Therefore, with careful monitoring and awareness of the potential complications, caudal epidural catheterization can be considered as an effective analgesic strategy for horses, particularly for conditions like orthopedic issues and synovial sepsis.
