Hyperproteic Nutrition:Correlation of BUN to Nitrogen Balance - Full Text View

Sponsored by:	Penn State University
Information provided by:	Penn State University
ClinicalTrials.gov Identifier:	NCT00480259

Purpose

This study is designed to determine if the following are true. When protein requirements exceed metabolic requirements, blood urea nitrogen(BUN) levels will rise. Elevated BUN levels in the absence of renal failure, hepatic failure, or GI bleeding, will be correlated with improved nitrogen balance and inversely correlated with infection rates, days of mechanical ventilation, ICU days, and total hospital days.

Condition	Intervention
Enteral Feeding	Behavioral: hyperproteic nutrition

Study Type:	Interventional
Study Design:	Diagnostic, Randomized, Single Blind, Dose Comparison, Parallel Assignment, Safety/Efficacy Study
Official Title:	Hyperproteic Nutrition; Correlation of BUN to Nitrogen Balance and Associated Infection Rates With Bimodal Protein Administration

Further study details as provided by Penn State University:

Primary Outcome Measures:

Increase in BUN

Secondary Outcome Measures:

Decrease in infection rate, ventilator days, ICU stay and hospital dys

Detailed Description:

The purpose of this study is threefold. First, to determine if a correlation exists between BUN and nitrogen balance in the context of hyperproteic nutrition administration. Creatinine clearance will also be followed to determine if there is any harmful effect to the kidney secondary to an elevated BUN. Secondly, to determine if there is a difference in hospital acquired infection rate, ventilator days, ICU days, and hospital stay between the current nutrition standard at Penn State Hershey Medical Center and a hyperproteic nutrition protocol.

Thirdly, to determine the accuracy of at least three calculated creatinine clearance formulae when compared to a measured creatinine clearance.
