title: Early use of cyclic TPN prevents further deterioration of liver functions for the TPN patients with impaired liver function.
abstract: OBJECTIVE
  Impaired liver function is frequently found in patients who need prolonged total parenteral nutrition. Cyclic total parenteral nutrition can minimize the adverse effects of long-term total parenteral nutrition, such as hepatic complication. The adequate timing to shift to use cyclic total parenteral nutrition for patients with impaired liver function may prevent further hepatic dysfunction.
  
  
  METHODS
  A prospective study of 65 patients who need total parenteral nutrition and have impaired liver functions was performed. Cyclic total parenteral nutrition was used in different groups of patients, when their total bilirubin levels were just over 5 mg%, 10 mg%, or 20 mg% during the course of total parenteral nutrition. The patients of control groups received straight non-cyclic total parenteral nutrition. All the patients had stable vital signs without major stress, such as sepsis or acute bleeding. Ten patients (A2) in Group A were shifted to cyclic total parenteral nutrition when their total bilirubin was just over 5 mg%; the other 10 patients (A1) continued the non-cyclic total parenteral nutrition. Eleven patients (B2) in Group B were shifted to cyclic total parenteral nutrition when their total bilirubin was just over 10 mg%; the other 11 patients (B1) continued the non-cyclic total parenteral nutrition. Ten patients (C2) in Group C were shifted to cyclic total parenteral nutrition when their total bilirubin was just over 20 mg%; the other 13 patients (C1) continued the non-cyclic total parenteral nutrition. The average energy intake among 3 groups had no difference. Their liver functions were examined each week for 2 weeks.
  
  
  RESULTS
  The results showed that the patients with non-cyclic total parenteral nutrition had significant increase of direct-total bilirubin and alkaline phosphatase (P < 0.05) in Group A and significant decrease of albumin accompanied with increase of GOT, GPT, direct/total bilirubin (P < 0.05) in Group B. The patients either using cyclic or non-cyclic total parenteral nutrition showed significant decrease of albumin and increase of direct/total bilirubin (P < 0.05) in Group C.
  
  
  CONCLUSIONS
  We conclude that the early use of cyclic total parenteral nutrition may prevent deterioration of liver function for the patients with jaundice and need prolonged total parenteral nutrition.
