Summary of caloric needs of critically ill and healthy individuals in the context of the Minnesota Starvation Study and actual current ICU calorie delivery
| Mean REE (kcal/day) | TEE (kcal/day) | TEE/weight (kcal/kg/day) | |
|---|---|---|---|
| Uehara et al., ICU study [12] | |||
| Sepsis patients (mean age 67) | |||
| Week 1 | ~ 1854 | 1927 ± 370 | 25 ± 5 |
| Week 2 | 3257 ± 370 | 47 ± 6 | |
| Trauma patients (mean age 34) | |||
| Week 1 | ~ 2122 | 2380 ± 422 | 31 ± 6 |
| Week 2 | 4123 ± 518 | 59 ± 7 | |
| WHO calorie requirements, healthy subjectsa | |||
| Men | ~ 3000 | 44 (range 35–53) | |
| Women | ~ 2500 | 36 (range 29–44) | |
| Minnesota Starvation Study calorie delivery | Delivered energy (kcal/day) | Delivered energy/weight (kcal/kg/day) | |
| Baseline period | 3200 | ~ 50 | |
| Starvation period | ~ 1800 | 23–30 | |
| Recovery period delivery (for recovery to occur) | ~ 4000 | ~ 60 | |
Actual average 1034 kcal/day delivered in critically ill patients over first 12 days of ICU stay [15]
