Nutrition therapy during noninvasive ventilation: oral or enteral?
Current Opinion in Critical Care 2023 August 2
PURPOSE OF REVIEW: Critical care nutrition guidelines primarily focus on patients receiving invasive mechanical ventilation, yet noninvasive ventilation (NIV) is an increasingly common intervention. The optimal route of nutrition delivery in patients receiving NIV has not been established. This review aims to describe the implications of NIV on the route of feeding prescribed.
RECENT FINDINGS: Five small, mostly observational, studies have quantified energy or protein intake in patients receiving NIV in critical care, which demonstrate intake to be poor. No study has assessed the impact of feeding route on outcomes. The predominant route of feeding observed is oral intake, yet nutrition intake via this route is lower than that from enteral or parenteral nutrition. Barriers to oral intake include fasting for intubation, the inability to remove NIV apparatus to eat, breathlessness, fatigue and poor appetite, while barriers to enteral nutrition include the impact of the naso-enteric tube on the mask seal and potential aspiration.
SUMMARY: Until evidence to support the optimal route of feeding is developed, patient safety should be the key driver of route selection, followed by the ability to achieve nutrition targets, perhaps utilizing a combination of routes to overcome barriers to nutrition delivery.
