TPN Summary


Top  Previous  Next


The TPN Summary tab displays calculated evaluation parameters about the TPN you have entered.


The TPN Summary must be viewed before you can save the TPN


Click the "Finish" button to save the TPN and exit the TPN Wizard.



Values outside of normal are flagged in red.  This does not mean that the TPN is wrong.  It is only meant to alert you to a potential order entry error.  You must use your professional judgement to determine if the TPN is appropriate for your patient.



The top line on the summary is a simple one line description of the base solution.


Nutritional needs

Below, the patient's nutritional needs are displayed next to the nutritional contents of the TPN.  The percentage from each calorie source is also displayed.


Evaluation parameters

Caloric density



Lipid infusion rate


Should not exceed 2.5 g/kg/day

Calcium:Phosphate solubilty product


Traditional: should not exceed 300

3-in-1: should not exceed 150

Glucose infusion rate


Should not exceed 5 to 7 mg/kg/min



Peripheral route should not exceed 900

Nitrogen:calorie ratio


Should be at least 1:133


Calcium phosphate solubility curve


Click the graph button to view the calcium phosphate solubility curve.  Solubility varies among the various amino acids and is dependent on amino acid concentration..


Total electrolytes

Finally, the total electrolytes are displayed, which is the sum of electrolyte additives plus those supplied by the amino acid solution.


If the electrolyte total is outside the usual maintenance range, it will flag in red.  This does not mean that the TPN is wrong, it is only meant to alert you to a potential order entry error.  Electrolyte additives must be tailored to the individual patient needs.



Adult usual requirement

Pediatric usual requirement


 60 to 200 mEq / day

 2 to 4 mEq / kg / day


 60 to 200 mEq / day

 2 to 4 mEq / kg / day


 8 to 40 mEq / day

 0.25 to 0.5 mEq / kg / day


 10 to 30 mEq / day

 0.5 to 3 mEq / kg / day


 10 to 40 mMol / day

 0.5 to 2 mMol / kg / day


 PRN acid-base balance

 Same as adults


 PRN acid-base balance

 Same as adults


Aluminum content

The FDA acceptable upper limit of aluminum exposure from parenteral products is 5 mcg/kg/day.   A toxic dose of parenteral aluminum is defined as 60 mcg/kg/day.


The aluminum content calculation shown is not the actual aluminum content, but rather the potential maximum content.


The program presents a "worst case" scenario, using the highest reported values for each component.  The aluminum content for individual components is set on the TPN components setup window.  You are advised to modify these values to match the TPN components that are used in your facility.
