Trophic Nutrition in ICU Patients Undergoing High-Flow Oxygen Therapy and/or Noninvasive Mechanical Ventilation: The Nutri-Trophic Study.

Enteral nutrition (EN) therapy in ICU patients requiring oxygen therapy with high-flow nasal cannula (HFNC) and/or noninvasive mechanical ventilation (NIMV) is controversial. A prospective, cohort, observational, and multicenter study was conducted in 10 ICUs in Spain to analyze the 90-day mortality, tolerance, side effects, and infectious complications of trophic EN in patients requiring HFNC therapy and/or NIVM. A total of 149 patients were enrolled. The mean age, severity scores, tracheobronchitis, bacteremia, and antimicrobial therapy were significantly higher in deceased than in living patients (p < 0.05), and the mortality rate was 14.8%. A total of 110 patients received oral trophic feedings, 36 patients received nasogastric tube feedings (NGFs), and 3 received mixed feedings. Trophic EN was discontinued in only ten (14.9%) patients because of feeding-related complications. The variables selected for the multivariate logistic regression on feeding discontinuation were SOFA upon admission (OR per unit = 1.461) and urea (OR per mg/dL = 1.029). There were no significant differences in the development of new infections according to the route of EN administration. Early trophic feeding administered to patients with acute respiratory failure requiring noninvasive ventilation is safe and feasible, and is associated with few dietary and infectious complications in a mortality, setting comparable to similar studies.

Aggressive lung donor management increases graft procurement without increasing renal graft loss after transplantation.

BACKGROUND: To determine the impact of an aggressive protocol on the rate of lung grafts available for transplant. We analyzed the impact of this management on kidney graft survival after kidney transplantation. METHODS: A cohort study. Lung donors and kidney recipients from 2009 and 2010 were considered the prospective cohort with 2003-2008 as the historical control period. The number of lungs available for transplantation was the main outcome measures. For recipients, kidney graft survival was the main outcome measure. RESULTS: We quadrupled the number of lung donors in the period 2009-2010 compared with the historical control. Management in the prospective cohort included higher use of positive end-expiratory pressure (PEEP) (p < 0.0001), increased use of hormonal resuscitation therapy (HRT) (p < 0.0001), and lower level of central venous pressure (p < 0.05) than historical control. The probability of renal graft survival at one yr after transplant was 88.6% (CI 95%: 74.8-95.1) in historical control and 94.7% (CI 95%: 81-98.7%) in the prospective cohort (p = 0.226). CONCLUSIONS: Aggressive management strategy in potential lung donors, which includes ventilator recruitment maneuvers, PEEP ≥ 8 cm H(2)O, the use of HRT, and restrictive fluid balance increases the rate of lung grafts available for transplantation without adverse effect on kidney graft survival.
