NCT01459341
First received: October 18, 2011
Last updated: December 5, 2012
Last verified: December 2012
  Purpose

Comparison of two non-invasive methods for measuring tissue oxygenation. One is Transcutaneous Oxygen Pressure (TCPO2) and the other is the new method of Near Infrared Spectroscopy (NIRS) - near infrared spectroscopy in patients with critical limb ischemia (CLI) undergoing invasive treatment (surgical or endovascular).


Condition

Primary Outcome Measures:
  • tissue oxygenation [ Time Frame: the outcome will be assessed during the hospital stay up to a week ] [ Designated as safety issue: No ]

Enrollment: 15
Study Start Date: July 2011
Study Completion Date: November 2012
Primary Completion Date: September 2012 (Final data collection date for primary outcome measure)
Detailed Description:

Comparison of two non-invasive methods for measuring tissue oxygenation. One is TCPO2 and the other is the new method of NIRS - near infrared spectroscopy in patients with critical limb ischemia (CLI) undergoing invasive treatment (surgical or endovascular).

The NIRS probe has been used to measure tissue oxygenation in the cerebral circulation up to now. While TCPO2 is the established method for measuring tissue oxygenation in patients with CLI to evaluate the potential for wound healing.
