History of Changes

Purpose

Monitoring and optimizing tissue oxygenation (StO2) in high-risk surgery and/or high-risk surgical patients may decrease the risk of postoperative complications.

Tissue hypoxia occurs frequently during high-risk surgery in high-risk patients. The investigators want to see if an algorithm aimed at optimizing intraoperative tissue oxygenation reduces perioperative complications as well as length of stay in the intensive care unit (ICU LOS), 28-day mortality, and the duration of mechanical ventilation in these patients.

Primary Outcome Measures:

incidence of perioperative complications [ Time Frame: during operation ] [ Designated as safety issue: Yes ]
organ dysfunction, SOFA score, troponin T, creatinin, CRP

Enrollment:	48
Study Start Date:	May 2011
Study Completion Date:	December 2012
Primary Completion Date:	December 2012 (Final data collection date for primary outcome measure)

Arms	Assigned Interventions
No Intervention: standard care The data from the InSPectra Monitor in the Control group will be inaccessible for the Investigator since this is not a part of their daily medical practice
Active Comparator: Treatment group, The data given by the monitor will be available for the Investigator and used to apply the optimization protocol	Device: connected to the InSpectra Monitor
