Symptoms first appear within 2 minutes of injection. Signs reported in humans include confusion, shivering, seizures, paralysis, loss of consciousness, apnea, hypotension, bradycardia, and nausea/vomiting [101]. Respiratory arrest is the most common sign in humans and can last up to 30–60 min [98]. Neurological signs tend to resolve in 1–2 hours post‐injection, although in some cases they may last for up to 12 hours [98]. In a cat that had suspected brainstem anesthesia following retrobulbar block during general anesthesia, the observed signs included apnea, tachycardia and hypertension, within 5 min of injection, and delayed recovery [100]. Upon recovery from anesthesia, the cat presented tremors and nystagmus, lasting 20 minutes, and absent menace response, mydriasis and lack of dazzle and pupillary light reflex lasting 3 hours.
