Measurements of muscular microcirculation by laser Doppler flowmetry in isoflurane and halothane anaesthetised horses.

The research paper examines the effects of two types of anesthesia, Isoflurane and Halothane, on the muscular microcirculation of horses. It was established that the use of Isoflurane resulted in less depression to the horses’ cardiovascular function as compared to Halothane, and a significant improvement was recorded in muscular microcirculation when measured by laser Doppler flowmetry.

Research Objective

• The main objective of this study was to compare the effects of two common anesthetic agents, Isoflurane and Halothane, on the cardiovascular function and muscular microcirculation of horses.

Methodology

• The study employed the use of laser Doppler flowmetry to measure muscular microcirculation. This technique makes use of the Doppler effect to measure the flow of red blood cells through blood vessels, providing an accurate and non-invasive method of assessing blood flow in the microcirculation of tissue.
• Horses undergoing surgery were anesthetised using either Isoflurane or Halothane.
• The cardiovascular reactions and muscular microcirculation of the horses were then monitored and recorded for comparison.

Findings

• The research results showed that the cardiovascular function of horses was considerably lesser depressed when Isoflurane was used for anaesthesia instead of Halothane.
• Furthermore, a significant improvement was seen in the muscular microcirculation of horses anaesthetised with Isoflurane, when measured by laser Doppler flowmetry.

Implications

• The findings of the study suggest that Isoflurane could be a more suitable anesthetic option for horses undergoing surgery, as it appears to cause lesser negative impact on the cardiovascular function and improves muscular microcirculation.
• The results also have potential prominence for veterinary practice, assisting in the choice and administration of anesthesia for equine surgery.
