NCT01352260

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

Outcome Measures

Primary Outcomes (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.

    At the end of the surgical case approximately 6 to 8 hours

Study Arms (1)

Cardiac Disease

Total Aortic Arch Replacement

Study Population

Baylor College of Medicine and affiliated Hospitals

You may qualify if:

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

You may not qualify if:

  • Patients will be excluded from this study if they are age less than 18
  • Are undergoing an emergent procedure
  • Have a history of insulin-dependent diabetes mellitus
  • Have a history of stroke
  • Are undergoing a redo sternotomy during which major bleeding occurs necessitating transfusion of \> 4 units of packed red blood cells prior to the institution of circulatory arrest
  • Patients in whom a left jugular venous bulb cannula cannot successfully be placed
