Net protein utilization during total parenteral nutrition of injured critically ill patients: an original approach
No full textTraumatized critically ill patients with either a moderate or severe catabolic response were studied. Patients were randomly allocated to receive an intravenous solution which was either protein-free or contained protein and hypertonic glucose. The overall energy intake in both groups was equivalent to each patient's daily requirement. In both the moderately catabolic and severely catabolic patients the urinary nitrogen loss with the protein-free solution was negatively correlated to the energy intake/energy need ratio (p less than 0.01, moderate catabolism; p less than 0.001, severe catabolism). The ratio of energy intake/energy need was correlated with the nitrogen loss. From the resultant straight line, the obligatory nitrogen loss was determined for those patients receiving the protein containing solution (test diet). The net protein utilization was subsequently calculated using this value of the obligatory nitrogen loss. The net protein utilization was inversely correlated with the severity of trauma. It was significantly (p less than 0.005) greater in the patients with a moderate catabolic response. In the acute postinjury phase, the net protein utilization of infused amino acids was similar to that for protein fed orally to normal healthy subjects

Combined use of mask CPAP and minitracheotomy as an alternative to endotracheal intubation. Preliminary observation
No full textWe describe the combined use of mask CPAP (continuous positive airway pressure) and minitracheotomy as an alternative to conventional endotracheal intubation in 3 patients requiring CPAP, secretion removal and diagnostic procedures such as bronchoalveolar lavage and bronchial cultures. These requirements were fulfilled with the combined technique approach, thus preserving glottic function and avoiding the disadvantages of endotracheal intubation of tracheotomy. This approach seems particularly suitable in the treatment of immunocompromised patients because of its reduced invasiveness
