Ultrasound-guided injection of bupivacaine into the cricoarytenoid dorsalis muscle as a novel technique for transiently inducing laryngeal hemiplegia in horses
The aim is to evaluate the effectiveness of ultrasound-guided injection of bupivacaine into the cricoarytenoid dorsalis muscle to induce laryngeal hemiplegia in horses.
Ultrasound-guided injection of bupivacaine was performed on the cricoarytenoid dorsalis muscle.
The study focused on assessing the technique's efficacy during maximal exercise.
The injection successfully induced transient laryngeal hemiplegia.
Effects were sustained for the duration of maximal exercise.
Abstract
Injecting bupivacaine into the CAD under ultrasound guidance is a practical technique for inducing transient LH that is sustainable during maximal exercise.
