Abstract
PURPOSE OF REVIEW: This is a review of recent literature on the role of indirect calorimetry in surgical nutrition. RECENT FINDINGS: All critical care societal guidelines recommend the use of indirect calorimetry as the standard of care to determine energy needs. Recent studies confirm discrepancy between measured and equation-predicted energy expenditure and further demonstrate improved outcomes with indirect calorimetry-guided nutrition. Patients that undergo ECMO, CRRT and those with COVID-19 would benefit from the use of indirect calorimetry. SUMMARY: Indirect calorimetry-guided nutrition is the standard of care in mechanically ventilated surgical patients.
