Near-Infrared Spectroscopy Comparison Study

May 18, 2012 updated by: Nonin Medical, Inc

Validation of Near-Infrared Spectroscopy for Neuromonitoring During Moderate Hypothermic Circulatory Arrest for Total Aortic Arch Replacement: A Comparison of Two Technologies With Jugular Venous Bulb Oximetry

The objective of this study is to validate Near-Infrared (NIRS) monitoring in patients undergoing circulatory arrest. This study will compare two-wavelength NIRS INVOS System, Somanetics; Troy, MI) with four-wavelength NIRS (Nonin Medical, Inc; Plymouth, MN) to determine which modality best correlates with jugular venous oxygen saturation

Description

Inclusion Criteria:

  1. Provide written informed consent from patient or legally authorized representative before surgery
  2. Adult patients 18-65 years of age
  3. Presenting for elective or urgent total aortic arch repair under moderate hypothermic circulatory arrest (Nasopharyngeal temperature 20 - 24 ºC) with selective antegrade cerebral perfusion -
