Brief Summary:
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

Condition or disease
Total Aortic Arch Replacement

Study Type : Observational
Actual Enrollment : 17 participants
Observational Model: Cohort
Time Perspective: Prospective
Official Title: 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
Study Start Date : May 2011
Actual Primary Completion Date : April 2012
Actual Study Completion Date : April 2012

Cardiac Disease
Total Aortic Arch Replacement

Primary Outcome Measures :
  1. Linear correlation between absolute value of cerebral oxygen saturation (rSO2) compared to Jugular Venous Oxygen Saturation (SjvO2). Sensitivity and specificity to detect < 60% desaturation. [ Time Frame: At the end of the surgical case approximately 6 to 8 hours ]
