Piperacillin/tazobactam in continuous infusion versus intermittent infusion in children with febrile neutropenia

ABSTRACT

Abstract Background Febrile neutropenia (FN) is a common complication in children who receive chemotherapy for cancer. Objective The objective of this study was to evaluate the clinical efficacy of the continuous versus intermittent infusion of piperacillin/tazobactam (TZP) in febrile neutropenic pediatric patients. Methods This is a non-blinded randomized controlled clinical trial. Eligible group consisted of hemato-oncological patients with FN who were candidates to receive TZP. Patients were randomized to one of two groups Group 1 received antibiotic treatment through intravenous intermittent infusion of TZP 300 mg/kg/day based on piperacillin, divided into four doses, not exceeding 16 g/day; Group 2 received an initial TZP loading dose of 75 mg/kg infusion over 30 min, and then a continuous infusion of TZP 300 mg/kg/day through central line with pump over 24 h. Results There were 176 episodes that could be assessed, 100 in Group 1 and 76 in Group 2. There was no statistically significant difference in treatment failure in the experimental group (continuous infusion) compared with the intermittent group, 21% versus 13% (p = 0.15). The increase in the absolute risk reduction was 0.08% (95% confidence interval 0.12-0.30), and the number needed to treat was 12.4. One patient in each group died. Conclusions There were no differences in fever resolution, clinical cure rate, or mortality when comparing the continuous with the intermittent TZP infusion.
