Clinicophysiological Effects of Intraspinal and Intramuscular Xylazine - Ketamine in Uremic Buffalo Calves.
2009
Pathak, Rekha | Kushwaha, R. B. | Kumar, Sanjay
Clinico-physiological effects of Xylazine - Ketamine were evaluated in 12 clinical cases of uremic buffalo calves having urolithiasis. In group A, Xylazine -Ketamine were used at the dose rate of 0.05 mg/kg body weight and 2.5 mg/kg body weight respectively to create regional spinal anesthesia at the lumbosacral space in 6 buffalo calves. In group B, Xylazine and Ketamine at the same dose rates were used intramuscularly in 6 buffalo calves. Analgesia was then recorded at different regions by the pin prick method and scored on a scale and motor incoordination, sedation, complete duration of anesthesia, complete recovery and physiological parameters (heart rate, respiration rate and rectal temperature) were evaluated in both the groups at various intervals of time throughout the duration of surgery of Tube cystotomy. It was found that the animals of group B achieved a safer physiological peak values than animals of group A.

An early declining trend in haemoglobin concentration, concurrent with reduced total erythrocyte count and PCV% was observed with pentazocine or lysine acetyl salicylate (LAS) analgesic premedication in thiobarbiturate intravenous general anaesthesia in atropine-primed normal dogs. While the declining trend in PCV% persisted with pentazocine, it had abated at 1.5 hr with LAS pre-medication. No evidence of intravascular haemolysis or red cell morphological aberration was found. Alterations in the values of major haematological indices appear to be a passive consequence of volume changes in the splenic pulp: initial dilatation induced by the thiobarbiturate followed by spontaneous contraction back to original biometry. The observed early lymphopoenic-eosinopoenic response might reflect enhanced glucocorticoid titre during the anaesthetic stress.
