Laser Doppler flowmetry: Muscular microcirculation in anaesthestised horses

Abstract

Summary Muscular microcirculation was studied in seven halothane anaesthetised horses in lateral recumbency using a laser Doppler flowmeter. A significant difference between the dependent and the uppermost triceps brachii was recorded. In the dependent muscles, microflow at first decreased and then increased up to the starting value. In the uppermost muscles, a significant rise of the microflow was measured.

The relationship of muscle perfusion and metabolism with cardiovascular variables before and after detomidine injection during propofol–ketamine anaesthesia in horses

“…Muscle perfusion has been studied during inhalation anaesthesia and different techniques such as laser Doppler flowmetry (LDF) (Serteyn et al. 1986; Serteyn et al.…”

Equine Postanesthetic Myositis: An Ischaemic Reperfusion Phenomenon

“…A catheter (90 cm, Biotrol) was also positioned in the right atrium via the jugular vein to collect mixed venous blood. The intracompartmental muscle pressure (ICMP) and the microcirculation (LDF) in the uppermost triceps brachii were measured respectively by the Wick catheter method and by Laser Doppler Flowmetry (Lindsay et al, 1980;Serteyn et al, 1986).…”

Skeletal muscle blood flow in anaesthetized horses. Part I: measurement techniques

“…Laser Doppler flowmetry has been used extensively to study relative changes in microvascular blood flow within the skeletal muscle of anaesthetized and conscious horses (Serteyn et al 1986;Norman et al 1992;Lee et al 1993). This technique uses the Doppler principle to detect the velocity of moving erythrocytes (RBCs) within the microvasculature.…”
