Core-peripheral temperature gradients in children after open heart surgery can indicate changes in intravascular volume. Monitoring these temperature changes provides valuable insights into a patient

Area of Science:

  • Pediatric Cardiac Surgery
  • Physiological Monitoring
  • Hemodynamic Assessment

Background:

  • Post-open heart surgery, accurate assessment of a child's hemodynamic status is crucial.
  • Core-peripheral temperature gradients are influenced by circulatory function.
  • Understanding these gradients can aid in managing fluid balance.

Purpose of the Study:

  • To investigate the relationship between core-peripheral skin temperature changes and hemodynamic parameters in children post-open heart surgery.
  • To determine if temperature gradients correlate with cardiac index, systemic vascular resistance, mean arterial pressure, or urinary output.
  • To assess the utility of core-peripheral temperature gradients as an indicator of intravascular volume status.

Main Methods:

  • Measurements of core and peripheral skin temperatures were taken in 10 children over 1-hour intervals post-surgery.

  • Hemodynamic parameters including cardiac index, systemic vascular resistance index, mean arterial pressure, and urinary output were recorded.
  • Spearman's rank correlation was used to analyze the relationship between temperature gradients and hemodynamic variables.

    • Main Results:

    • No significant correlations were found between changes in core-peripheral temperature gradient and cardiac index, systemic vascular resistance index, mean arterial pressure, or urinary output.
    • A significant correlation was identified between changes in central venous pressure and the core-peripheral temperature gradient.

    Conclusions:

    • Changes in the core-peripheral temperature gradient after open heart surgery in children correlate with central venous pressure.
    • The core-peripheral temperature gradient may serve as a valuable, non-invasive indicator of a patient's intravascular volume status.
    • Further research can explore the clinical application of temperature monitoring for fluid management in pediatric cardiac patients.
