Safety of rapid intravenous paracetamol infusion in paediatric patients

Purpose

Paracetamol is recommended as a first-line treatment for pain and fever in paediatric patients. Intravenous (IV) infusions are recommended to be administered as a 15-min infusion to minimize local tissue trauma and related pain. The purpose of this study was to demonstrate that IV paracetamol could be administered during 5 ​min or less in paediatric patients without causing related adverse reactions.

Methods

Prospective, observational safety study including children aged <18 years who received IV paracetamol. Pain scores before and after the paracetamol infusions were obtained using VAS, FLACC, COMFORT neo, or COMFORT behaviour scales with scores from 0 to 10 representing no pain to worst pain. Further, objective signs of inflammation at the infusion site were registered.

Findings

We included 44 patients (median age 2.8 years, range 0.01–17.0 years) who received paracetamol in a peripheral venous catheter (n ​= ​22) or central venous catheter (n ​= ​22). In total, the 93 paracetamol infusions had a median infusion time of 3:00 ​min, range 0:40 to 5:00 ​min. After infusions, pain scores were lower, compared to before infusions (mean change −0.26, 95% confidence interval −0.45 to −0.07, P ​= ​0.007), and no objective signs of inflammation were reported.

Implications

This safety study indicates that IV paracetamol can be administered in paediatric patients with a shorter infusion time than recommended without causing adverse reactions. The results may contribute to a more efficient workflow at paediatric departments.
