A Trial to Assess the Effect of High Nitrogen Intake in Critically Ill Patients
2020年5月23日 更新者：Ming Zhong、Shanghai Zhongshan Hospital
The Efficacy and Safety of High Nitrogen Intake in Critically Ill Patients: a Randomized and Controlled Trial
The patients with sepsis are in high risk of malnutrition, which could contribute to infection, difficulty in weaning from ventilators.
The investigators speculate whether nutrition therapy with high nitrogen could attenuate the malnutrition status and improve the outcome in these sepsis patients.
In this prospective Randomized Controlled Trial, the investigators aim to compare high nitrogen intake with conventional nitrogen supply which were recommended in guidelines.

有源比较器：conventional nitrogen
In this arm, daily nitrogen supply is 1.2-1.5g
per kilogram (lean mass weight) as recommended by ESPEN guideline
|
Nitrogen supply could be administered through amino acid in parenteral nutrition, proteins in enteral nutrition.
