Heart rate in pediatric trauma: rethink your strategy

Area of Science:

• Pediatric trauma care
• Cardiovascular physiology in children
• Shock assessment in pediatrics

Background:

• Optimal heart rate (HR) in pediatric trauma is typically based on resting values, which may not accurately reflect physiological needs post-injury.
• Understanding HR variations after trauma is essential for accurate shock staging and timely intervention.
• Current resting HR ranges may not align with the HRs associated with the lowest mortality in pediatric trauma patients.

Purpose of the Study:

• To analyze admission HRs in pediatric trauma patients.
• To determine HR ranges associated with the lowest mortality across different age groups.
• To compare trauma-associated HRs with traditional resting HR ranges.

Main Methods:

• Utilized the National Trauma Data Bank (2007-2011) for patients aged 1-14 years.
• Stratified patients into eight age-based groups for analysis.
• Employed regression analysis to calculate mortality odds ratios (ORs) for various HR ranges within each age group.

Main Results:

• Analyzed 214,254 pediatric trauma patients; overall mortality was 0.8%.
• The lowest mortality risk for patients aged 5-14 was observed at an HR of 80-99 bpm.
• HR ranges linked to lowest mortality varied by age and were narrower than standard resting HRs in children aged 7-14.

Conclusions:

• Admission HRs associated with lowest mortality in pediatric trauma often deviate from established resting HRs.
• A 7-year-old with an HR of 115 bpm might indicate Stage III shock, contrary to traditional normal ranges.
• Accurate identification of critical HRs in pediatric trauma is vital for effective clinical management and treatment guidance.
