Local anesthesia: synovial

Contributor(s): John Dodam, Prof Stephen Greene

Introduction

Uses

  • To relieve synovial pain.
  • To locate painful lameness (diagnostic technique).
  • For postoperative analgesia after intra-articular surgery Stifle: intra-articular stabilization.
  • Local anesthetics Local anesthesia: overview (ie lidocaine Lidocaine or bupivacaine Bupivacaine ) can be used to provide synovial anesthesia. Bupivacaine often preferred because of long duration of action (~4-6 h).
  • Opioids Analgesia: opioid (ie morphine Morphine ) can be used to provide synovial analgesia. Although opioid receptors are traditionally thought of as residing in the central nervous system, opioid receptors are expressed in traumatized or inflamed synovial membranes. The expected duration of morphine-induced analgesia is ~8-12 h.

Advantages

  • Minimal systemic effects.
  • Anesthesia of affected joint.

Disadvantages

  • Limited to large synovial joints (ie the stifle).
  • Relatively short duration of action (hours).
