Figure 2From: Endogenous glutamine production in critically ill patients: the effect of exogenous glutamine supplementationPlasma glutamine concentration in mechanically ventilated patients on full nutrition in the ICU (n = 11). The basal sample was taken immediately before the start of exogenous intravenous glutamine supplementation with L-alanyl-L-glutamine (filled symbols, n = 6), or after a washout period of 4 h following the termination of the intravenous glutamine supplementation with L-alanyl-L-glutamine (open symbols, n = 5). Mean values with SD are indicated by filled squared symbols. ***Iincrease in plasma glutamine concentration statistically significant, P = 0.0004.Back to article page
