MRI studies may be useful in identifying the location and extent of brain injury in patients with cyanide-induced Parkinsonian syndrome. In a prospective study, hydroxocobalamin appeared safe in fire victims with or without cyanide poisoning. Clinical features include coma, respiratory arrest and cardiovascular collapse. Additional studies for patients exposed to hydrogen cyanide include ECG monitoring, determinations of serum lactate and urinary thiocyanate, chest radiography, and pulse oximetry (or ABG measurements) (Hall and Rumack 1998).
