Surgical Management of Mechanical Intestinal Ileus under Right Paravertebral Nerve Block and Lignocaine Continuous Rate of Infusion in Cattle

Mechanical intestinal ileus is an abdominal emergency that is potentially life threatening in cattle. Early diagnosis and surgical correction is challenging for clinician under field conditions. Successful outcome depends upon effective management of visceral pain during surgical procedure and restoration of early intestinal motility. The present study is aimed to study the quality of visceral analgesia using right paravertebral nerve block and lignocaine continuous rate of infusion in standing surgery and prokinetic effect of azithromycin.

The present work was carried out from April 2019 to September 2021, in 6 cattle presented to the veterinary clinical complex, veterinary college and research institute, Namakkal with a history of not voiding the dung. In all the cases, clinical, haematological, biochemical, ultrasonographic, anaesthetic, prokinetic evaluation and surgical management was performed.

In the present study, inclusion of lignocaine as intravenous bolus @ 2 mg/kg body weight and continuous rate infusion (CRI) dose of 50 μg/kg/min produced good quality of visceral analgesia and no animal was recumbent intraoperatively. Prokinetic action of azithromycin was found effective to control the post-operative ileus in intestinal surgical procedures.
