Abstract:
The study was carried out in 12 clinical cases of cattle to assess the cardiovascular effects of intravenous continuous rate infusion of lignocaine as an adjunct to general anaesthesia for intestinal surgeries. The animals were indiscriminately selected and categorized equally into two groups. All the animals were premedicated with dexmedetomidine and butorphanol tartrate at the dose rate of 0.5 µg per kg and 20 µg per kg body weight i.v. respectively. After five minutes of premedication, induction of anaesthesia was achieved with double drip solution containing ketamine hydrochloride 2 mg and guaifenesin 50 mg per mL respectively, administered i.v. “to effect”. Anaesthesia was maintained with isoflurane in all the animals. In group II animals ten minutes prior to skin incision, slow intravenous lignocaine bolus at the dose rate of 2 mg per kg and continuous rate infusion at the dose rate of 50 µg per kg per min was delivered through volumetric infusion pump. There was no significant difference in cardiovascular parameters noticed between the group which signifies that intravenous lignocaine at this dose in anaesthetised cattle is cardiovascular dynamic.
