Abstract To verify that variations caused by total parenteral nutrition (TPN) in O2 intake (VO2) and CO2 output (VCO2) can affect respiratory function of non-hypercatabolic patients, we studied 18 patients in two groups; group I (control): eight patients receiving 75–100g glucose/24 h, and group II: ten patients fed intravenously on 13.6 g N2 and approximately 2,800 kcal/24 h given as a) 62% glucose+38% fats (TPN-G+F) and b) 100% glucose (TPN-G). VO2, VCO2, respiratory quotient (RQ) and minute ventilation (VE) were measured in all patients. We found that VCO2 was 27% higher in intravenously fed patients (p〈0.01 andp〈0.02). similarly, VE was 26% higher in intravenously fed patients (p〈0.001 andp〈0.02). Comparison of TPN-G+F and TPN-G results showed no differences in VCO2; by contrast, VO2 was 21% less during TPN-G(p〈0.01).
