Portacath with dilantin occlusion

I need a reference to create a policy for Na Bicarb instillation to treat a dilantin precipitae. I have the new INS standards in front of me but the refences refer to tpa, ethanol and HCL.

The articles referenced in

The articles referenced in Standard 56, Practice Criteria F provide you with a discussion of alteration of pH by using either Na Bicarb or hydorchloric acid. These discussions are based in basic chemistry. Phenytoin has a pH of 11-12 or highly alkaline. Precipiate occurs because that high pH has dropped. To reverse the precipitate, you raise the pH with bicarb. I don't think you will find any actual clinical studies reporting the outcomes of the use of each solution. Lynn
