Monitoring both procalcitonin and C-reactive protein in the early period after tetralogy of Fallot correction in children promotes rational antibiotic use.

Abstract

PURPOSE:

This retrospective cohort study aimed to identify the early postoperative kinetics of C-reactive protein (CRP) and procalcitonin (PCT) in children undergoing tetralogy of Fallot (ToF) correction. The ability of these inflammatory markers to guide rational antibiotic usage was also determined.

MATERIALS AND METHODS:

All consecutive children who underwent ToF correction in 2009-2016 in our referral pediatric cardiac surgery clinic in Gdansk, Poland and did not exhibit infection signs on early postoperative days (POD) were identified. All patients received 48h antibiotic prophylaxis. Antibiotic treatment was extended or empirical antibiotic therapy was introduced if the clinician considered it necessary. CRP and PCT levels were measured on POD1-4 and 1-3, respectively.

RESULTS:

Of the 60 eligible children, 44 underwent CRP testing only. The remaining 16 patients underwent both CRP and PCT testing. All patients had abnormally high CRP values after surgery. All patients who also underwent PCT testing also displayed elevated PCT levels. The CRP and PCT levels peaked on POD2 (median=99.8mg/L) and POD1 (median=4.08ng/mL), respectively. In the CRP-alone patients, antibiotic prophylaxis was prolonged or empirical antibiotic therapy was started in 59%; in the CRP and PCT group, this was 25% (p<0.05).

CONCLUSIONS:

The children had elevated CRP and PCT levels after ToF correction, with peaks observed on POD2 and POD1, respectively. Monitoring both CRP and PCT in the early postoperative period may guide antibiotic therapy, thus reducing unnecessary treatment, additional toxicity, and adverse drug interactions without increasing treatment failure. Rational antibiotic treatment may also reduce antibiotic resistance.
