Abstract
OBJECTIVE
To compare thoracic ultrasonographic findings in healthy horses before and after general anesthesia for elective MRI utilizing a recently developed ultrasonographic scoring system to aid clinicians in the early identification of pneumonia following anesthesia.
ANIMALS
13 adult horses > 3 years of age.
PROCEDURES
Prior to anesthesia, horses underwent a thorough physical examination, CBC, thoracic radiography, and thoracic ultrasonography. Horses were then anesthetized for elective MRI, and thoracic ultrasonography was repeated within 3 hours after recovery. Thoracic ultrasonographic findings were scored utilizing a recently developed scoring system, and scores were compared before and after anesthesia.
RESULTS
There was no significant difference identified in total thoracic ultrasonography score before and after anesthesia, and there was no correlation between thoracic ultrasonography score following anesthesia and the body weight of the horse, the time recumbent, and the dependent side.
CLINICAL RELEVANCE
In healthy horses undergoing anesthesia for elective imaging, there was no significant change in thoracic ultrasonographic findings 3 hours after recovery from anesthesia. These data can aid clinicians in determining the clinical significance of ultrasonographic changes in the lung in the immediate postanesthetic period.
Abstract
OBJECTIVE
To determine the accuracy of 2 interstitial glucose-monitoring systems (GMSs) for use in horses compared with a point-of-care (POC) glucometer and standard laboratory enzymatic chemistry method (CHEM).
ANIMALS
8 clinically normal adult horses.
PROCEDURES
One of each GMS device (Dexcom G6 and Freestyle Libre 14-day) was placed on each horse, and blood glucose concentration was measured via POC and CHEM at 33 time points and compared with simultaneous GMS readings. An oral glucose absorption test (OGAT) was performed on day 2, and glucose concentrations were measured and compared.
RESULTS
Glucose concentrations were significantly correlated with one another between all devices on days 1 to 5. Acceptable agreement was observed between Dexcom G6 and Freestyle Libre 14-day when compared with CHEM on days 1, 3, 4, and 5 with a combined mean bias of 10.45 mg/dL and 1.53 mg/dL, respectively. During dextrose-induced hyperglycemia on day 2, mean bias values for Dexcom G6 (10.49 mg/dL) and FreeStyle Libre 14-day (0.34 mg/dL) showed good agreement with CHEM.
CLINICAL RELEVANCE
Serial blood glucose measurements are used to diagnose or monitor a variety of conditions in equine medicine; advances in near-continuous interstitial glucose monitoring allow for minimally invasive glucose assessment, thereby reducing stress and discomfort to patients. Data from this study support the use of the Dexcom G6 and Freestyle Libre 14-day interstitial glucose-monitoring systems to estimate blood glucose concentrations in horses.
