Uso da detomidina no acuponto Yin Tang em equinos

Abstract

The α2 adrenergic agonists are used to promote quality sedation, but also cause deleterious effects on physiological parameters. The present study aimed to analyze the quality of equine sedation with anesthetic underdose of detomidine in the Yin Tang acupoint. To that end, six healthy horses receiving 0.013 mg/kg of detomidine in the Yin Tang acupoint were evaluated head height, visual stimulus response, response to sound stimulus, heart rate, PR interval, respiratory rate, systolic blood pressure, rectal temperature and blood glucose at baseline (T0) and at five different times (T1, T2, T3, T4 and T5) with a 15 minute interval between them. Statistical difference (p≤0.05) was obtained for the parametric data of head height with greater reduction in T2 (40.33 ± 10.33) and heart rate with the lowest mean in T1 (27.83 ± 1, 92). The non-parametric data of response to the sound stimulus and response to visual stimulus presented zero score (no response) in T2. The administration of detomidine in the Yin Tang acupoint promoted sedation, without significant interference in the clinical parameters, showing a safe alternative in the anesthetic protocols of horses.
