Anaesthetic evaluation of lignocaine alone and in-combination with butorphanol in goats

Abstract

The objective of study was to assess the quality of analgesia and record the alteration in anaesthetic indices following lumbosacral administration of lignocaine alone @ 4 mg/kg body weight in group I and its combination with butorphanol@ 0.04 mgkg body weight in group II. Onset of analgesia in both groups was evident at 5 min and reached to peak level at 15 minutes of observation. The incoordination and sedation was more marked in butorphanol groups as compared to lignocaine groups. The onset of analgesia was delayed in group II as compared to group I, whereas, duration of analgesia and standing time was significantly higher (P less than 0.05) in group II as compared to group I. Time to recumbency did not revealed significant variation between groups. It is concluded that lignocaine alone and in-combination produced satisfactory onset of analgesia but it remained longer time in lignocaine – butorphanol group (group II) with respect to duration of analgesia and time to standing. However, this combination also showed the marked sedation and incoordination. Hence, butorphanol in combination with lignocaine was considered better for producing analgesia for longer duration operative procedure.
