CRRT and calories

  Q: Continuous renal replacement therapy (CRRT) can be a source of calories to patients in ICU?

A) True

B) False

Answer: A

As a standard of practice, a solution with a concentration of 100 mg/dL of glucose is used during CRRT. Moreover, citrate solution is also added as a normal practice. 

There is a net calorie deliverance of 512 kcal per day on average by the use of glucose and citrate solutions during CRRT. This should be taken into account while calculating patients' total calorie count for the day.
