Clinical Assessment of an Ipsilateral Cervical Spinal Nerve Block for Prosthetic Laryngoplasty in Anesthetized Horses.

Abstract: The nociceptive blockade of locoregional anesthesia prior to surgical stimulation can decrease anesthetic agent requirement and thereby potential dose-dependent side effects. The use of an ipsilateral second and third cervical spinal nerve locoregional anesthetic block for prosthetic laryngoplasty in the anesthetized horses has yet to be described. Anesthetic records of 20 horses receiving locoregional anesthesia prior to laryngoplasty were reviewed and compared to 20 horses of a similar patient cohort not receiving locoregional anesthesia. Non-blocked horses were 11 times more likely to require adjunct anesthetic treatment during surgical stimulation (P = 0.03) and were 7.4 times more likely to receive partial intravenous anesthesia in addition to inhalant anesthesia (P = 0.01). No horse in the blocked group received additional sedation/analgesia compared to the majority of non-blocked horses (75%) based on the anesthetist's perception of anesthetic quality and early recovery movement. No difference in recovery quality was observed between groups (P > 0.99). Cervical spinal nerve locoregional anesthesia appears well-tolerated and useful in reducing cumulative anesthetic agent requirement and may decrease the need for additional sedation/analgesia in horses undergoing anesthetized prosthetic laryngoplasty.

The study investigates the impact of applying a local anesthesia block to the cervical spinal nerves of horses prior to a surgical procedure, namely prosthetic laryngoplasty. This method reveals effectiveness in lesser use of anesthetic agents, which translates into a reduced risk of dosage-related side effects.

Overview of the Research

  • The researchers were primarily studying the effects of using a locoregional anesthetic block on the second and third cervical spinal nerves before a prosthetic laryngoplasty procedure in anesthetized horses.
  • The main purpose of this was to see if this method could help in reducing the need for anesthetic agents which often come with dose-dependent side effects.

Methodology

  • They evaluated the anesthetic records of 40 horses. 20 of these had been administered locoregional anesthesia prior to laryngoplasty, while the other 20, who made up the control group, had not been given the same treatment.
  • The two groups of horses were similar in terms of other patient characteristics.

Results

  • The evaluations showed that those horses that didn’t receive the locoregional block were 11 times more likely to require additional anesthetic treatment during the procedure, signifying the potential to reduce the amount of general anesthesia used.
  • The non-blocked horses were also 7.4 times more likely to require partial IV anesthesia in addition to inhalant anesthesia which suggests that the locoregional block might have useful effects on pain management during the procedure.
  • More interestingly, none of the horses that received the locoregional block needed any further sedation or pain relief, as opposed to 75% of those horses that hadn’t received the same treatment.
  • Lastly, there was no observable difference between the two groups in terms of their recovery quality after the surgery.

Conclusion

  • The study concludes that cervical spinal nerve local anesthesia could be a potential way of reducing the cumulative requirement of anesthetic agents in horses undergoing prosthetic laryngoplasty.
  • Importantly, this could lead to a decrease in the need for further sedation or pain relief, therefore limiting potential dose-dependent side effects.
