[{'content': 'Inhalation agent incompatable with sodaline \nSelect and explain. \nA. Isoflurane, B. Trichloro Ethylene, C. Methoxy flurane, D. Enflurane', 'role': 'user'}, {'content': 'Answer: B \nExplanation: B i.e. Trichloro ethylene Sodalime with trilene forms phosgene (neurotoxic) gas.Q So this combination is contraindicated. Sodalime is a mixture of 94% (Ca(OH)2 + 5% NaOH as catalyst + 1% KOHQ; with granule size of 4-8 meshQ. It should not be used with : The drier the sodalime, the more likely it will degrade & absorb volatile anesthetics. It produces compound A with sevofluraneQ (clinically significant) and carbon monoxide with desflurane, isoflurane & enflurane (clinically insignificant). However, desflurae can be broken down to CO by dry barium hydroxide lime to such an extent that it is capable of causing clinically significant CO poisoning.', 'role': 'assistant'}]
