Plain-English summary
A 545-kg Quarter Horse developed serious muscle twitching and a rapid heartbeat during anesthesia for cataract surgery after receiving a medication called succinylcholine. This caused a rise in body temperature and breathing issues while still under anesthesia. Although the horse experienced muscle inflammation after the surgery, it ultimately recovered well.

Abstract
A syndrome similar to malignant hyperthermia developed in a 545-kg Quarter Horse while anesthetized with halothane for cataract removal. Succinylcholine administration caused prolonged, severe muscle fasciculations followed by tachycardia, and an elevated blood pressure. Later, while the horse was still under anesthesia, its body temperature rose 2 degrees C, and respiratory acidosis developed. Myositis developed after surgery, but the horse recovered.
