Veterinary Anaesthesia and Analgesia

Abstract

To assess cardiopulmonary and analgesic effects after administration of ropivacaine into the caudal epidural space of cattle. Prospective, single-dose trial. Eight healthy mixed breed cows aged 8 ± 5 years and weighing 507 ± 112 kg. Caudal epidural anesthesia was produced in cows with 0.75% ropivacaine (0.11 mg kg(-1)). Onset time, duration and cranial spread of analgesia were recorded. Heart rate (HR), respiratory rate (f(R)), rectal temperature (RT), and mean arterial blood pressure (MAP) were measured prior to epidural administration (T(0) ) and at 15, 30, 60, 120, 180 and 240 minutes after epidural administration (T(15), T(30), T(60) , T(120) , T(180) and T(240) ). Arterial blood acid-base balance (pH, standard bicarbonate and base excess), gas tension (PaO(2), PaCO(2), SaO(2)) and electrolytes (Na(+), K(+), iCa(2+),Cl(-)) were recorded at T(0), T(30), T(60), T(120), T(180) and T(240). Ataxia was evaluated at T(0), T(30), T(60), T(120), T(180) and T(240) and at 1 hour intervals thereafter until analgesia was no longer present in each animal. Epidurally administered ropivacaine induced variable analgesia extending bilaterally from the coccyx to S3. Time to onset of analgesia and mean duration in the perineal area were 15 ± 4...Continue Reading
