NIRF Trial: Near-Infrared Spectroscopy for Intraoperative Restriction of Fluids Trial (NIRF)

This study has been completed.
Information provided by:
Hutchinson Technology Inc Identifier:
First received: August 7, 2008
Last updated: October 28, 2009
Last verified: October 2009

The purpose of this study is to evaluate if the InSpectra StO2 Monitor can safely guide the amount of fluid needed during colorectal surgery.

The study hypothesis is that intraoperative fluid limitation can be safely accomplished when guided by StO2 monitoring, and that this fluid restriction regimen will result in a reduction in postoperative morbidity when compared to standard monitoring and fluid therapy.

Condition Intervention
Colorectal Surgery Procedure: Restricted intraoperative fluid management

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double Blind (Participant, Care Provider, Outcomes Assessor)
Primary Purpose: Supportive Care
Official Title: Near-Infrared Spectroscopy for Intraoperative Restriction of Fluids Trial A Prospective Randomized Study of Near-infrared Spectroscopy Directed Fluid Therapy vs Standard Fluid Therapy in Patients Undergoing Open Elective Colorectal Surgery
