[{'content': 'Trilene is degraded by: \nSelect and explain. \nA. Enzymatic Degradation, B. Non Enzymatic degradation, C. Chemical Degradation, D. None', 'role': 'user'}, {'content': 'Answer: A \nExplanation: * Trilene or trichloroethylene is a good analgesic, less depressant, and non-flammable. * Cardiac dysrhythmia, or tachypnoea may occur during administration. * It should not be used in the closed circuit as it reacts with soda-lime to produce a toxic gas(phosgene). * Recovery is slow and nausea as well as vomiting may be present. * It should not be used with adrenaline infiltration lest dysrhythmia be conveed to ventricular fibrillation. Degradation: * Brought about by enzymatic degradation * The enzyme that stas one branch of this pathway, toluene 1,2-dioxygenase, has many other catalytic abilities, which are documented in a table of the Reactions of Toluene 1,2-Dioxygenase. * The spontaneous degradation of trichloroethylene epoxide can produce as many as four products: dichloroacetate, carbon monoxide, glyoxylate, and formate. The number, type, and propoion of products seen depends on the local environment REF : BAILEY AND LOVE 27TH ED', 'role': 'assistant'}]
