I think Metheny NA has published several articles on tube feeding and respiratory outcomes,

e.g. JPEN J Parenter Enteral Nutr. 2011 May;35(3):346-55.

Relationship between feeding tube site and respiratory outcomes.

Metheny NA, Stewart BJ, McClave SA.

Am J Crit Care. 2006 Jul;15(4):360-9.

Preventing respiratory complications of tube feedings: evidence-based practice.

Metheny NA.

I hope this helps you out

I agree that Metheny NA has several atilce regarding enteral nutrition and respitaory complications.

There is another review artilce on that : Risk of aspiration in patients on enteral nutrition: frequency, relevance, relation to pneumonia, risk factors, and strategies for risk reduction.Curr. Gastroenterol.res. 2007,Aug 9(4): 338-44,

Another article is: Risk factor for aspiration. Risk factors for aspiration. JPEN Parenter Enteral Nutr, 2002 Nov-Dec;26(6 Suppl):S26-31; discussion S32-3..Metheny NA

Hi Johny and Rejina,

Thank you for your answers! It's true that Metheny NA published several articles on enteral nutrition and respiratory outcomes. I checked them during my literature research and my impression was, that she rarely proved her statements and that she unfrequently cite studies but rather narrativ reviews (unsystematic and subjectiv). I found an critical article from Gomes et al (2003) which was very helpfull:

Gomes, G.F.; Pisani, J.C.; Macedo, E.D. & Campos, A.C. (2003): The nasogastric feeding tube as a risk factor for aspiration and aspiration pneumonia. Current Opinion in Clinical Nutrition and Metabolic Care, 6 (3), 327–333.

Anyway, it's an difficult theme because of the unclear diagnostic of the pneumonia and aspiration pneumonia. I hope it's getting gradually clearer.
