What is the new evidence for possible adjusting the guideline on waiting for hemodynamic stability, volume resuscitation and mesenteric perfusion prior to starting enteral feeds?

• A. A recent prospective randomized trial confirms guideline changes are necessary.
• B. A recent retrospective trial indicates early enteral nutrition in hemodynamically unstable patients receiving mechanical ventilation may decrease mortality; however, due to inherent study limitations further prospective randomized trials are needed before guideline changes can be made
• C. There is no evidence to support any change.
• D. Early enteral nutrition always improves outcomes.

Answer: (B)
