TASK: Your task is to answer biomedical questions using the given abstract. Only output yes, no, or maybe as answer.
INPUT: ['To report a case of restored patency of a central venous access device occluded by precipitate of phenytoin sodium injection.', 'A patient experienced total occlusion of an implanted subcutaneous port caused by precipitation of phenytoin. Phenytoin sodium injection was mixed inadvertently with dextrose 5% in NaCl 0.45% injection during intravenous administration. Dextrose 5% in NaCl 0.45% injection, which is acidic (pH 4.0), caused the phenytoin sodium injection, a basic solution (pH 12.0), to precipitate. Local instillation of sodium bicarbonate 8.4% injection to decrease the pH of the medium restored patency of the occluded port.'] Do dissolution of phenytoin precipitate with sodium bicarbonate in an occluded central venous access device?
OUTPUT:

agent
yes
