Patients on TPN who have such clots occluding their catheter may receive a thrombolytic flush to dissolve the clots and prevent further complications.
Chronic IV access leaves a foreign body in the vascular system, and blood clots on this IV line are common. Patients on TPN who have such clots occluding their catheter may receive a thrombolytic flush to dissolve the clots and prevent further complications.
Fatty liver is usually a more long term complication of TPN, though over a long enough course it is fairly common. The pathogenesis is due to using linoleic acid an omega-6 fatty acid component of soybean oil as a major source of calories.

Patients who eat food despite the inability can experience a wide range of complications. Total parenteral nutrition increases the risk of acute cholecystitis  due to complete disuse of gastrointestinal tract, which may result in bile stasis in the gallbladder.
Other potential hepatobiliary dysfunctions include steatosis ,  steatohepatitis , cholestasis , and cholelithiasis. The formation of sludge is the result of stasis due to lack of enteric stimulation and is not due to changes in bile composition. Gallbladder sludge disappears after 4 weeks of normal oral diet. Administration of exogenous cholecystokinin CCK or stimulation of endogenous CCK by periodic pulse of large amounts of amino acids have been shown to help prevent sludge formation.

Liver dysfunction can be limited to a reversible cholestatic jaundice and to fatty infiltration demonstrated by elevated transaminases. Severe hepatic dysfunction is a rare complication.

It is recommended that parenteral nutrition administration begin after a period of natural nutrition so doctors can properly calculate the nutritional needs of the fetus. Solutions for total parenteral nutrition may be customized to individual patient requirements, or standardized solutions may be used.
The use of standardized parenteral nutrition solutions is cost effective and may provide better control of serum electrolytes. For energy only, intravenous sugar solutions with dextrose or glucose are generally used. This is not considered to be parenteral nutrition as it does not prevent malnutrition when used on its own. Standardized solutions may also differ between developers. Following are some examples of what compositions they may have.
The solution for normal patients may be given both centrally and peripherally. Prepared solutions generally consist of water and electrolytes; glucose , amino acids , and lipids; essential vitamins , minerals and trace elements are added or given separately.
