Topic:Cerebrospinal Fluid
Cerebrospinal fluid (CSF) is a clear, colorless fluid found within the central nervous system of horses, circulating around the brain and spinal cord. It serves multiple physiological functions, including cushioning the brain and spinal cord, maintaining intracranial pressure, and facilitating the exchange of nutrients and waste products. In equine medicine, CSF analysis is a valuable diagnostic tool for assessing neurological conditions, as changes in its composition can indicate the presence of diseases such as infections, inflammations, or trauma. This page compiles peer-reviewed research studies and scholarly articles that explore the composition, function, and clinical relevance of cerebrospinal fluid in horses.
Cardiopulmonary measurements in nonanesthetized, resting normal ponies. Cardiopulmonary measurements were determined in 19 nonanesthetized, normal ponies. Mean values for arterial pressure, pulmonary arterial pressure, cardiac output, heart rate, packed cell volume, and hemoglobin are reported, as well as acid-base determinations of arterial blood and cerebrospinal fluid. Respiratory function test data include total ventilation, respiratory rate, alveolar ventilation, oxygen uptake, and carbon dioxide output. The data compare favorably with the available data from previous reports on ponies. Because of large day-to-day variations in total ventilation, alveolar ven...
Cerebrospinal fluid alkalosis during high-altitude sojourn in unanesthetized ponies. Unanesthetized adult female ponies were studied near sea level (250 m) and during sojourns to 3400 m (N=6) and 4300 m (N=7) altitude. The pH, PCO2, and PO2 of arterial blood and pH and PCO2 of cerebrospinal fluid (CSF) were measured under conditions of acute (1 hr) and chronic (1-45 days) hypoxia. Cerebrospinal fluid was sampled from the cisterna magna of the awake pony and arterial blood withdrawn from an indwelling arterial catheter. In both groups of animals, PaCO2 decreased slightly after 1 hr of hypoxia (delta PaCO2= - 0.6 mm Hg at 3400 m; - 3.9 mm Hg at 4300 m), decreased further after 1...
Cerebrospinal nematodiasis of Equidae. A review of 6 cases of equine cerebrospinal nematodiasis diagnosed between 1958 and 1971 indicated that 2 major clinical syndromes occur—chronic incoordination and an acute progressive fatal encephalitic disease. The gross lesions of acute cases occur most commonly in the centrum ovale and the cerebellar roof nuclear region and appear as hemorrhagic serpentine tracks. The invariable existence of endocardial or proximal aortic verminous lesions caused by Strongylus vulgaris in horses with verminous encephalitis circumstantially incriminates S. vulgaris parasitic emboli as the most common caus...
