I have a question about TPN compatibility. We have a patient with a single lumen CVC who is receiving triple antibiotics....Ampicillin, Gentamicin and Vancomycin. I know Amp isn't compatible but there is conflicting info regarding Vanco and Gent. I say they all aren't compatible because the pt has a single lumen catheter. Even if you used a y-site it doesn't matter you have to stop the TPN to administer the antibiotics. Any input would be much appreciated. Thx!
