Sensory nerve conduction and nociception in the equine lower forelimb during perineural bupivacaine infusion along the palmar nerves.

The purpose of this investigation was to study lateral palmar nerve (LPN) and medial palmar nerve (MPN) morphology and determine nociception and sensory nerve conduction velocity (SNCV) following placement of continuous peripheral nerve block (CPNB) catheters along LPN and MPN with subsequent bupivacaine (BUP) infusion. Myelinated nerve fiber distribution in LPN and MPN was examined after harvesting nerve specimens in 3 anesthetized horses and processing them for morphometric analysis. In 5 sedated horses, CPNB catheters were placed along each PN in both forelimbs.

Repeated occurrence of jejuno-jejunal intussusception in a calf.

This paper reports the clinical findings, diagnostic imaging, surgical management, and necropsy of an unusual case of jejuno-jejunal intussusception in a calf that was diagnosed with the use of ultrasonography, and treated surgically by resection and end-to-end anastomosis. The calf fatally relapsed 8 d after laparotomy. Necropsy and histology revealed enteritis and myenteric ganglionitis.

Spinal epidural abscess in two calves.

Objective: To report clinical signs, diagnostic and surgical or necropsy findings, and outcome in 2 calves with spinal epidural abscess (SEA).

Study Design: Clinical report.

Animals: Calves (n=2).

Development of a technique for continuous perineural blockade of the palmar nerves in the distal equine thoracic limb.

Objective: To develop a technique for placing continuous peripheral nerve block (CPNB) catheters adjacent to palmar nerves in horses and to evaluate the effect of low-volume local anesthetic (LA) infusion on nociception in the distal equine thoracic limb.

Study Design: In vitro and in vivo laboratory investigation. STUDY MATERIAL AND ANIMALS: Forty-two thoracic limbs from 22 equine cadavers and five horses.
