Physiological and biochemical effects of glyceryl guaiacolate-thiopentone sodium anaesthesia in buffalo calves

Glyceryl guaiacolate was used with thiopentone sodium for general anaesthesia in 10 clinically healthy male buffalo calves. When the animals were in the stage of surgical anaesthesia, there was marked hypotension and tachycardia along with a decrease in central venous pressure, tidal volume, partial pressure of oxygen in arterial blood and venous plasma potassium. Hyperglycaemia was another consistent feature. The changes in the acid base status were mild and inconsistent.
