C-reactive protein response following pediatric orthopaedic surgery

Area of Science:

• Pediatric Orthopaedics
• Clinical Chemistry
• Immunology

Background:

• C-reactive protein (CRP) is a key biomarker for inflammation and infection.
• Understanding the typical CRP response post-surgery is crucial for accurate clinical interpretation.
• Pediatric CRP responses may differ from adult patterns, necessitating specific pediatric research.

Purpose of the Study:

• To characterize the pediatric C-reactive protein (CRP) response following elective orthopedic surgery.
• To determine if CRP levels in children normalize within three weeks, similar to adults.
• To establish a baseline for identifying postoperative infections in pediatric orthopedic patients.

Main Methods:

• Prospective study involving 22 children undergoing elective orthopedic procedures.
• Serum CRP levels measured pre-operatively and on post-operative days 3, 7, and 21.
• Analysis focused on the pattern of CRP rise, fall, and normalization.

Main Results:

• CRP levels on day 3 post-surgery ranged from normal to a mean of 7.3 mg/dL (up to 22.2 mg/dL).
• By day 7, mean CRP levels decreased to 2.2 mg/dL.
• All pediatric patients exhibited normal CRP levels by the 3-week post-operative mark; no infections were reported.

Conclusions:

• The C-reactive protein (CRP) rise following pediatric orthopedic surgery can be more variable than in adults.
• In the absence of infection, pediatric CRP levels normalize within three weeks post-orthopedic surgery.
• This study provides valuable data for the clinical assessment of postoperative inflammation and infection in children.
