Normal postoperative febrile response in the pediatric orthopaedic population

Area of Science:

• Pediatric Orthopaedics
• Clinical Research
• Medical Informatics

Background:

• Postoperative fever in pediatric orthopaedic patients is a persistent clinical concern.
• Previous research indicated fever is an unreliable predictor of surgical complications.
• Establishing expected fever parameters based on perioperative factors is crucial for patient assessment.

Purpose of the Study:

• To develop guidelines for expected postoperative fever in pediatric orthopaedic patients.
• To introduce a novel metric, Total Febrile Response (TFR), for a more sensitive fever assessment.
• To identify perioperative variables that predict TFR.

Main Methods:

• Retrospective study of 177 pediatric orthopaedic patients.
• Development of composite temperature curves to calculate Total Febrile Response (TFR).
• Multivariate analysis to correlate perioperative conditions with TFR.

Main Results:

• Intraoperative transfusion status and estimated blood loss were significant predictors of TFR.
• Guidelines were established for expected fever based on surgery magnitude, duration, transfusion, blood loss, age, and gender.
• TFR provides a cumulative assessment of fever, considering both magnitude and duration.

Conclusions:

• The study provides a new tool for assessing postoperative fever in pediatric orthopaedic patients.
• TFR, influenced by intraoperative transfusion and blood loss, helps determine if fever is within expected limits.
• This approach enhances the clinical assessment of postoperative recovery by contextualizing fever within individual patient variables.
