Abstract

Six dogs irrespective of age and sex, categorised as class Ⅰ or Ⅱ as per American Society of Anaesthesiologists (ASA) classification, presented to Department of Veterinary Surgery & Radiology for various elective surgeries were selected for this study. All the animals under study were pre-anaesthetised with glycopyrrolate intravenously and anaesthesia was induced using a combination of xylazine-butorphanol-midazolam-ketamine intramuscularly. An intravenous loading dose of lignocaine was given after which anaesthesia was maintained with xylazine-midazolam-lignocaine-ketamine as continuous rate infusion. Induction of anaesthesia, using the drug combination under study was found to be satisfactory in all the six animals. The time taken for induction of anaesthesia ranged from three to five minutes, with a mean ± SE value of 4.33 ± 0.33 minutes. Quality of maintenance was judged good with good relaxation of abdominal muscles and jaw and good depth of anaesthesia. The time taken for recovery ranged from 22 to 49 minutes with a mean ± SE value of 34 ± 4.35 minutes. Recovery was smooth with out any complications noticed.
