The Effectiveness of C-Reactive Protein Surveillance as a Method to Monitor the Post-Operative Antibiotics Administration after Total Knee Replacement Arthroplasty
Abstract
Purpose
To evaluate the effectiveness of using C-reactive protein (CRP) surveillance as a method to monitor the effect of postoperative antibiotics for the prevention of early infection after total knee replacement arthroplasty (TKRA).
Materials and Methods
A prospective study was performed in 115 primary TKRAs. We examined the values of CRP of all cases on the 3rd, 5th, 7th, 10th and 14th days post-operatively. Some patients were administrated additional antibiotics under certain specific situations based on the pattern of CRP. The patients were divided into two groups: group I with planned period of administration and group II with administration longer than the planned period.
Results
No acute infection after TKRA due to CRP surveillance was observed. The mean duration of antibiotics administration was 5.9 days in all cases, 5 days in group I and 13.3 days in group II. Twelve cases (10.4%) were included in group II. The CRP was increased on the 5th and 10th days after operation in group II.
Conclusion
The surveillance of CRP was thought to be helpful in monitoring the effects of post-operative antibiotics and prevention of early infection after TKRA.
