All Surgical Procedures Result in Some Degree of Tissue Trauma and Associated Pain

There are 3 main reasons to minimize acute, post-surgical pain¹:

  • Ethical obligation to minimize pain and suffering
  • Pain delays healing and return to function
  • Unmanaged, acute pain can lead to chronic, maladaptive pain

Most dogs and cats are discharged from the hospital within 24-48 hours after surgery. Therefore, there is a need to provide analgesia for consistent pain relief from the post-operative period into recovery at home.

Local Anesthetics: The Most Effective Class of Analgesics for Peri-Operative Pain Control

Local anesthetics (LAs) are one of the most effective means of preventing transduction and transmission of pain signals.

  • Block sodium channels on the nerve cell membrane
  • Prevent propagation of action potentials (pain signals)
  • Considered safe, with side effects generally limited to very high doses. LAs do not appear to delay tissue healing1

While current AAHA/AAFP and WSAVA Pain Guidelines advocate for the use of LAs post-operatively, there are limitations: 1,2

  • Short duration of action (<8 hours) of available LAs
  • Technical difficulty associated with some nerve and epidural blocks
  • Complications of indwelling soaker catheters

Learn about the only long-acting local anesthetic that controls post-op pain with one dose for up to 72 hours.

Effective pain management generally involves a balanced or multimodal strategy … Local anesthetics are the only class of drug that renders complete analgesia.
