Summary
This study establishes reference intervals for procalcitonin (PCT) and C-reactive protein (CRP) after major abdominal surgery. These findings aid in interpreting infection markers in postoperative patients.
Area of Science:
- Biochemistry
- Clinical Diagnostics
- Surgical Medicine
Background:
- Procalcitonin (PCT) is a biomarker for bacterial infections and systemic inflammation.
- Interpreting PCT and CRP levels requires established reference intervals for specific patient populations.
- Major abdominal surgery can influence PCT and CRP concentrations.
Purpose of the Study:
- To establish continuous reference intervals for plasma PCT and CRP in the first week post-major abdominal surgery.
- To provide a graphic display of expected mean and upper reference limits for PCT based on postoperative day 1 values.
Main Methods:
- Analysis of PCT and CRP concentrations in 47 patients with a normal postoperative course.
- Monitoring biomarker levels during the first week following major abdominal surgery.
Main Results:
- Mean PCT concentration decreased by half within 2 days post-surgery.
- Mean CRP concentration increased in the first 48 hours, reaching half its maximum by day 5.
- Continuous reference intervals for PCT and CRP were developed for the early postoperative period.
Conclusions:
- The study provides essential reference intervals for PCT and CRP in the context of major abdominal surgery.
- These reference intervals can improve the interpretation of infection markers in postoperative patients.
- PCT and CRP exhibit distinct concentration dynamics in the early postoperative phase.
