Topic:Manometry
Manometry in horses refers to the measurement of pressure within the gastrointestinal tract, providing insights into the motility and functional status of the digestive system. This technique is used to assess conditions that affect the normal movement of the gut, such as colic or other gastrointestinal disorders. By evaluating the pressure patterns and coordination of muscular contractions, veterinarians can better understand the underlying causes of digestive issues in horses. Commonly studied regions include the esophagus, stomach, and intestines. This page compiles peer-reviewed research studies and scholarly articles that explore the methodologies, applications, and clinical implications of manometry in equine gastrointestinal health.
Evaluation of a rebound tonometer for measuring intraocular pressure in dogs and horses. To compare intraocular pressure (IOP) measurements obtained with a rebound tonometer in dogs and horses with values obtained by means of applanation tonometry and direct manometry. Methods: Prospective study. Methods: 100 dogs and 35 horses with clinically normal eyes, 10 enucleated eyes from 5 dogs, and 6 enucleated eyes from 3 horses. Methods: In the enucleated eyes, IOP measured by means of direct manometry was sequentially increased from 5 to 80 mm Hg, and IOP was measured with the rebound tonometer. In the dogs and horses, results of rebound tonometry were compared with results of applana...
Effects of treatment with oxytocin, xylazine butorphanol, guaifenesin, acepromazine, and detomidine on esophageal manometric pressure in conscious horses. To compare effects of oxytocin, acepromazine maleate, xylazine hydrochloride-butorphanol tartrate, guaifenesin, and detomidine hydrochloride on esophageal manometric pressure in horses. Methods: 8 healthy adult horses. Methods: A nasogastric tube, modified with 3 polyethylene tubes that exited at the postpharyngeal area, thoracic inlet, and distal portion of the esophagus, was fitted for each horse. Amplitude, duration, and rate of propagation of pressure waveforms induced by swallows were measured at 5, 10, 20, 30, and 40 minutes after administration of oxytocin, detomidine, acepromazine, xyl...
Esophageal dysfunction in a weanling thoroughbred. A 6-month-old Thoroughbred colt was examined because of persistent dysphagia noted since birth. Moderately severe regurgitation occurred when the colt ate semi-solid food or drank. Complete esophageal impaction developed when the colt ate solid material. Endoscopic examination revealed ulceration, dilatation and lack of peristalsis in the area of the previous impaction. Barium esophagram demonstrated the dilatation in the area of the previous impaction. Esophageal manometry revealed prolonged simultaneous contractions throughout the esophagus suggesting the presence of a motor abnormality. The...
