Evaluation of a Radial Arterial Line's Effect on StO2 Monitoring
- Conditions
- Oxygenation
- Interventions
- Device: StO2 monitoring
- Registration Number
- NCT00298090
- 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.

Group Intervention Description StO2 values StO2 monitoring StO2 monitoring
- Primary Outcome Measures
Name Time Method Tissue Oxygen Saturation (StO2) Measurement on the Extremity With a Radial Arterial Line up 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.
