Trial summary

Transcutaneous capnometry (tPCO₂) is a non-invasive method for continuous monitoring of ventilation status. In pediatric intensive care patients, it may reduce the need for repeated arterial or arterialized blood sampling. Read more about this study

About this study

Official title: Comparison of Transcutaneous Carbon Dioxide Monitoring With Arterialized or Arterial Blood Gas Analysis in PICU

Transcutaneous capnometry (tPCO₂) is a non-invasive method for continuous monitoring of ventilation status. In pediatric intensive care patients, it may reduce the need for repeated arterial or arterialized blood sampling. However, the accuracy of tPCO₂ may be influenced by factors such as peripheral perfusion, skin temperature, and vasopressor therapy. This prospective observational study compares transcutaneous carbon dioxide measurements with arterialized or arterial blood gas PaCO₂ values in children with respiratory insufficiency, including a subgroup receiving vasopressor support.

Read the detailed description

This prospective observational study will be conducted in a pediatric intensive care unit to assess agreement between transcutaneous carbon dioxide monitoring and arterialized or arterial blood gas analysis. Consecutive pediatric patients aged 1-18 years with respiratory insufficiency or impaired peripheral perfusion requiring vasopressor support will be included if repeated blood gas sampling is clinically indicated.

Paired measurements of tPCO₂ and PaCO₂ will be analyzed using Bland-Altman methods with correction for repeated measures. Subgroup analyses will evaluate the influence of vasopressor therapy on measurement accuracy. Secondary analyses will compare tPO₂ and PaO₂ values. The study aims to define the clinical applicability and limitations of transcutaneous capnometry in critically ill pediatric patients.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Partial CO2 difference

    Agreement between transcutaneous CO₂ (tPCO₂) and arterialized or arterial PaCO₂ assessed using Bland-Altman analysis (bias, SD, 95% limits of agreement).

    Measured: periprocedural

Secondary outcomes (3)
  1. Proportion of pCO2

    Proportion of tPCO₂ values within ±1 kPa of PaCO₂

    Measured: periprocedural

  2. Partial O2

    Agreement between transcutaneous oxygen (tPO₂) and PaO₂

    Measured: periprocedural

  3. Vassopressor use

    Subgroup analysis based on presence of vasopressor support

    Measured: periprocedural
