Observations on the use of glyceryl guaiacolate as an adjunct to general anaesthesia in horses.

This study examines the use of glyceryl guaiacolate as an aid to general anaesthesia in horses during clinical surgery or diagnostic procedures. The researchers found that the use of glyceryl guaiacolate assisted in smoothly inducing anaesthesia, maintaining it, and transitioning to recovery.

Methodology and Findings

• The researchers experimented on twenty-one horses which had to undergo clinical surgery and diagnostic procedures. In order to induce anaesthesia, these horses were given 15% glyceryl guaiacolate followed by a rapid intravenous injection of a thiobarbiturate. The horses were premedicated with atropine and acepromazine.
• The researchers observed that the induction of anaesthesia was smooth and without problems, although some horses did experience transient apnoea.
• Anaesthesia was maintained with oxygen and halothane, which were administered through a closed circle system with a soda lime absorber and the vaporiser out of circuit.
• Following the induction of anaesthesia, the heart rate of the horses increased and their respiratory rate fell.
• Out of the total, blood gas estimations were carried out on 6 horses during anaesthesia. The researchers observed respiratory acidosis in these horses, which is a condition where there is too much carbon dioxide (CO2) in the body.
• The scientists observed that the arterial blood oxygen tension values in these horses were higher than those reported in conscious horses.

Conclusion

• The researchers concluded that the use of glyceryl guaiacolate in this manner effectively and safely induces anaesthesia.
• It also enables a smooth transition to a period of stable maintenance, followed by an uneventful and quiet recovery. This makes it a potentially viable and advantageous method for inducing and maintaining anaesthesia in horses undergoing surgical or diagnostic procedures.
