Abstract
The present study was conducted to evaluate the
clinico-physiological effects of epidural
anaesthesia using lignocaine alone and in
combination with ketamine in cow calves. Eight
clinically healthy non-descript, stall- fed male
cow calves aged 7 to 8 months and weighing 55 to
65 kg were used in the study. Animals were divided
in two groups of four animals each. In (group A)
lignocaine @ 0.5mg/kg body wt. and in (group B)
lignocaine @ 0.5mg/kg body wt with ketamine @ 2
mg/kg body wt. was administered at first inter
coccygeal epidural space. Clinical observations
such as, onset, depth of analgesia, area of
desensitization, motor incoordination, salivation,
heart-rate, respiration rate and rectal
temperature (OF) were recorded before and at 5,
10, 20, 30, 45, 60, 90, 120, 150,180 and 240
minutes after injection of drug(s). Ruminal
movements were recorded at every 30 minutes after
the injection of drug(s) upto complete recovery
and 24 hours after the injection. The onset of
analgesia in group B was significantly shorter as
compared to group A. Group B animals induced
deeper analgesia as compared to group A. In group
A animals decrease in heart rate was recorded
whereas in group B animals heart rate was
increased. In group A, decrease in RR was
observed.
