Plain-English summary
A mature horse had a serious reaction while under anesthesia for a scan of its maxillary sinus after receiving a contrast dye called diatrizoate. This reaction caused the horse to have trouble breathing and low oxygen levels. The veterinarians treated the horse with a medication to open the airways, another to help with heart rate, and provided extra oxygen. Thankfully, the horse recovered well and was sent home without any further issues. It's important to be careful when using contrast dyes in horses that are anesthetized.
Abstract
A mature horse developed acute signs of bronchoconstriction causing hypoxemia and hypercapnia during anesthesia for computerized tomography of the maxillary sinus after i.v. administration of diatrizoate contrast medium. The horse was treated with aerosolized albuterol, atropine, and oxygen insufflation and recovered uneventfully despite severe hypoxemia and low hemoglobin saturation. The horse's condition continued to improve after treatment, and the horse was discharged with no further complications. Caution is advised with the use of contrast media in anesthetized horses.
