“…A Korean study reported inaccuracy of predictive equations in liver transplant patients and recommended using IC to avoid over- and underfeeding [ 28 ]. Measured REE was significantly associated with age, sex, Model for End-Stage Liver Disease score before liver transplant, surgery time, and graft cold ischemia time on a multiple regression analysis in a cohort of liver transplant patients on postoperative day six [ 29 ]. Given these associations along with directly observed inaccuracy using the Harris–Benedict formula, the authors concluded that fixed factors should not be used to determine energy expenditure and that IC should be used for liver transplant patients.…”

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.

“…Independent factors associated with the REE measured 6 days after LTx were reported to be the MELD score before the surgery, the surgical time, and the time of cold ischemia 52 . Ferreira et al also identified presurgery mREE values (β = 0.56) and the triceps skinfold thickness (β = 10.84) as predictors of mREE after LTx.…”

“…6,54 Cross-Sectional Studies Some authors evaluated mREE of LTx patients only after surgery. 55,56 The mREE of 143 patients 52 was assessed within a median time of 6 days after LTx and compared with the pREE (HB) (mean mREE: 1950 ± 461 kcal [24.5 ± 6.1 kcal/kg] and mean pREE: 1695 ± 256 kcal). Only 22% of patients had an mREE within 90%-110% of the pREE, and the mREE ranged from 61% to 195% of the pREE.…”

“…62 It is important to highlight that this review encompasses studies conducted at different times, and thus variability in the types of calorimeters used to determine the mREE cannot be ruled out. However, majority of the studies were performed using the Deltatrac calorimeter 35,37,39,9,40,46,24,26,27,49 and the COSMED, 6,28,50,53,52 which have previously been validated for accuracy. 63,64 Furthermore, in longitudinal studies, all the assessments were conducted using the same device.…”

Patients with end‐stage liver disease (ESLD) and undergoing liver transplantation (LTx) commonly present with malnutrition attributed to various etiologies. One of the causes is potential hypermetabolism resulting from increased resting energy expenditure (REE). After the surgery, it is hypothesized that these patients show a reduction in REE, which may contribute to the weight gain observed in this population. However, there have been controversial results regarding the metabolic status of ESLD patients and liver recipients, which has led us to critically review the pertinent literature. We enrolled studies with the following goals: assessment of REE of these patients either before or after surgery by using indirect calorimetry (measured REE [mREE]) and comparison of these mREE values with those of healthy controls or with REE values obtained using predictive equations (predicted REE [pREE]). For most patients, mREE and pREE values were comparable. However, ≥5.3% of patients exhibited hypermetabolism when the mREE was compared with the pREE using the Harris‐Benedict formula. Three follow‐up studies that were conducted postsurgery showed a progressive reduction in the mREE for ≤1 year. However, conflicting data have been published, and cross‐sectional studies have not reported hypometabolic patients. In conclusion, there is no consensus regarding the metabolic status of pre‐LTx and post‐LTx patients, which may be due to differences in the methods used for comparison. Therefore, we highlight this aspect of LTx patient management, which impacts the quality of nutrition therapy required by these patients.
