Continuous arterial gas monitoring: initial experience with the Paratrend 7 in children
1Division of Pediatric Critical Care Medicine, UCLA Children's Hospital, UCLA School of Medicine 90095, USA.
Insights
Continuous arterial blood gas monitoring using the Paratrend 7 device in children provided reliable data for up to seven days. This technology aids in managing critically ill pediatric patients in the intensive care unit.
Area of Science:
- Pediatric Critical Care Medicine
- Biomedical Engineering
- Clinical Monitoring Technology
Background:
- Continuous monitoring of arterial blood gases is crucial for managing critically ill children.
- Existing methods often involve intermittent sampling, which can delay critical treatment decisions.
Observation:
- The Paratrend 7 continuous arterial blood gas monitor was evaluated in children older than 24 months requiring ventilatory support.
- The sensor was inserted via an arterial catheter to measure pH, PCO2, PO2, and temperature.
- Simultaneous arterial blood gas values were recorded alongside sensor readings for comparison.
Findings:
- The Paratrend 7 sensor functioned effectively for up to seven days, providing continuous respiratory status data.
- Statistical analysis demonstrated acceptable bias and precision for pH (0.006/0.024), PCO2 (-0.78/4.68 mmHg), and PO2 (1.9%/17.1%).
Implications:
- This study validates the clinical utility of continuous blood gas monitoring in pediatric intensive care.
- The Paratrend 7 offers valuable, real-time data to enhance the management of critically ill children.
- Continuous monitoring can lead to more timely interventions and improved patient outcomes.
Objective:
To describe clinical usage of the Paratrend 7 continuous arterial blood gas monitor in children.
Design:
Children older than 24 months of age who required significant ventilatory intervention were eligible for sensor placement.
Interventions:
The sensor was placed via the arterial catheter to measure pH, PCO2, PO2, and temperature. The simultaneous arterial blood gas value was recorded along with the sensor reading.
Results:
The sensor functioned for as long as seven days and provided the clinicians with data on the patient's respiratory status. The statistical validity of the device when compared to the arterial blood gas showed that the bias/precision for pH was 0.006/0.024, for PCO2 -0.78/4.68 mmHg, and for PO2 1.9%/17.1% (mmHg).
Conclusions:
This report demonstrates actual clinical use of continuous blood gas monitoring in children. The information obtained is a major asset to the management of critically ill children in the intensive care unit.
