Value of C-reactive protein in detecting complications after open-heart surgery in children
1Children's Hospital, University of Helsinki, Finland.
Insights
Serum C-reactive protein (CRP) levels and body temperature can help detect complications after pediatric open-heart surgery. Higher CRP and temperature indicate increased risk in children, with age influencing the response.
Area of Science:
- Pediatric Cardiac Surgery
- Biomarkers in Surgery
- Postoperative Care
Background:
- Open-heart surgery in children presents unique postoperative challenges.
- Monitoring patient recovery is crucial for early detection of adverse events.
- Serum C-reactive protein (CRP) is a known inflammatory marker.
Purpose of the Study:
- To investigate the utility of serum C-reactive protein (CRP) and body temperature in identifying postoperative complications in children undergoing open-heart surgery.
- To explore the relationship between patient age, CRP levels, and surgical outcomes.
- To assess the diagnostic value of serial CRP measurements for early complication detection.
Main Methods:
- Retrospective review of 206 children undergoing primary open-heart surgery.
- Daily measurements of serum C-reactive protein (CRP) and body temperature for 14 days post-surgery.
- Comparison of CRP levels and temperature between children with and without complications.
Main Results:
- CRP levels peaked on postoperative day 2 (128 +/- 57 mg/l).
- Children with postoperative complications (38%) exhibited significantly higher CRP concentrations and body temperatures compared to those with uneventful recovery.
- Increasing age was associated with elevated CRP levels, suggesting age-dependent inflammatory responses.
Conclusions:
- Serial CRP measurements, alongside body temperature, can serve as valuable indicators for detecting postoperative complications in pediatric cardiac surgery patients.
- Age is a modifying factor in the CRP response to surgery and complications.
- Early identification of complications through CRP monitoring can potentially improve patient outcomes.
Abstract:
Measurements of serum C-reactive protein (CRP) and body temperature daily for 14 days after primary open-heart surgery were retrospectively reviewed in 206 children with mean age 4.6 years. CRP rose postoperatively, reaching maximum (128 +/- 57 mg/l) on day 2. Postoperative complications occurred in 78 children (38%), 14 of whom died. CRP concentrations were significantly higher in patients with complications than in those with uneventful recovery. Rising age was associated with greater elevation of CRP levels. Body temperature was higher in children with complications. The age of the child thus modified the CRP response to surgery and to postoperative complications. Serial measurements of CRP may be useful in detecting postoperative complications in children who have undergone open-heart surgery.
