Trials of miscellaneous interventions to wean from mechanical ventilation.

We found eight randomized controlled trials (RCTs) of miscellaneous interventions that were designed to facilitate the process of weaning from mechanical ventilation. The two RCTs of high-fat/low-carbohydrate enteral nutrition found favorable physiologic effects on CO2 production and respiratory quotient, rendering this type of nutrition potentially useful in patients with impaired ventilatory reserve; however, no conclusions can be made about …
