Evaluation of a Radial Arterial Line's Effect on StO2 Monitoring

Completed
Conditions
Oxygenation
Interventions
Device: StO2 monitoring
Registration Number
NCT00298090
Lead Sponsor
The University of Texas Health Science Center at San Antonio
Brief Summary

Measuring tissue oxygen saturation (St02) in the thenar eminence is emerging as a measurement of resuscitation. However, no study to our knowledge has evaluated the effects of an arterial line in the radial artery supplying this muscle bed on St02. This study will attempt to address the interaction between an arterial line and St02 monitoring in the thenar eminence. As most patients who require aggressive resuscitation will have an arterial line, it is important to understand what if any impact this will have on St02 in the same extremity.

Primary Outcome Measures
NameTimeMethod
Tissue Oxygen Saturation (StO2) Measurement on the Extremity With a Radial Arterial Lineup to 15 minutes

Using near-infrared spectroscopy, the external device recorded raw StO2 values every 3.5 seconds for approximately 5 minutes prior to and immediately following the insertion of a radial arterial catheter on the ipsilateral side. The raw values were then compiled into one-minute averages.
