A Randomized Controlled Study of Enteral Nutrition in Septic Shock

Not Applicable

Completed

• Conditions: Septic Shock
• Interventions: Other: Enteral nutrition

• Registration Number: NCT02025127
• Lead Sponsor: Medical College of Wisconsin

Brief Summary

There is a paucity of data on the timing and role of enteral nutrition in septic shock.

The primary aim of this study is to conduct a phase III single-center pilot randomized controlled trial comparing early trophic enteral nutrition to 'no enteral nutrition' in mechanically ventilated septic shock patients to determine feasibility.

Detailed Description

Septic shock represents the body's dysregulated response to an infection, manifesting as persistent hypotension (mean arterial pressure \< 70 mmHg) despite intravenous (IV) fluid resuscitation. Severe sepsis and septic shock are major healthcare problems, affecting millions of people around the world each year In critically ill patients without shock, provision of enteral nutrition within 24-48 hours has shown to preserve intestinal epithelium, maintain brush border enzyme activity, maintenance of barrier function to enhance immune function, and preservation of tight cell junctions to reduce permeability. These benefits of enteral nutrition are postulated to prevent downstream complications of nosocomial infections and the multiple organ dysfunction syndrome (MODS), though direct data addressing this question are lacking.

The primary aim of this study is to conduct a phase III single-center pilot randomized controlled trial comparing early trophic EN to 'no EN' in mechanically ventilated septic shock patients to determine feasibility of achieving \>75% consent and compliance rate and \<10% contamination rate.

Arm && Interventions

Group	Intervention	Description
Trophic feeding	Enteral nutrition	Mechanically ventilated patients with septic shock \> 18 years old randomized to this group will receive more than 50 but less than 600 kilocalories of enteral nutrition per day while on vasopressors. This will be started within 24 hours of intensive care unit admission.

Primary Outcome Measures

Name	Time	Method
number of patients consenting to study and remaining compliant with assigned study arm	46 months	consent and compliance rate of \>75% and contamination rate \<10%

Secondary Outcome Measures

Name	Time	Method
intensive care unit free days	30 days	number of days alive and out of the intensive care unit out of 30
Ventilator free days	30 days	Number of days alive and off mechanical ventilatory support out of 30
Hospital mortality	30 days	number of patients who died during hospitalization
change in 48 hour sequential organ failure assessment score, with higher score representing worse outcome	48 hours	absolute change in sequential organ failure assessment score (range 0-24 points) from day 0 to 48 hours, with higher scores representing worse outcomes
