Reaching Protein Target With SmofKabiven® Extra Nitrogen vs Olimel N9E During the Early Phase of Acute Critical Illness

The main focus of the study is to show that SmofKabiven® extra Nitrogen, in a realistic clinical setting, enables to meet high protein requirements in patients during the first week after onset of critical illness, without risk of overfeeding with energy.
