  Purpose
The purpose of this study is to examine the agreement between venous blood gas and arterial blood gas measurements in patients in the Intensive Care Unit.

Condition Intervention
Acid-Base Balance Procedure: Venous blood gas analysis

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Diagnostic
Official Title: Agreement Between Venous and Arterial Blood Gas Measurements in the Intensive Care Unit

Further study details as provided by University of California, Los Angeles:

Primary Outcome Measures:
  • Agreement between venous and arterial blood gas measurements of pH, pCO2 and bicarbonate [ Time Frame: Duration of Intensive Care Unit Admission ]

Enrollment: 40
Study Start Date: January 2008
Study Completion Date: July 2008
Primary Completion Date: July 2008 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
1 Procedure: Venous blood gas analysis
When an ABG is deemed to be necessary as part of ICU management, a central venous sample will also be obtained with minimum delay (always < 2 minutes) between the samples. The samples will be analyzed by a blood gas analyzer as quickly as possible.

Detailed Description:
Venous blood gas analysis may be an alternative to arterial blood gas analysis for acid-base status, reducing the need for frequent invasive arterial sampling. The objective of this study is to examine the agreement between ABG and VBG samples for all commonly used parameters (pH, pCO2 and bicarbonate) in a pathologically diverse ICU patient population, specifically analyzing multiple paired arterial and venous samples from each patient.
