Aim:
Intraosseous access is an alternative to conventional intravenous access. A number of studies have demonstrated the utility and safety of EZ-IO, a recently introduced semi-automatic intraosseous device. However, few studies have investigated the use of EZ-IO in the paediatric emergency setting. The aim of this study was to describe the epidemiological characteristics EZ-IO use including complications among paediatric patients in a paediatric emergency department.
Methods:
We conducted a retrospective descriptive study enrolling children younger than 16 years who visited our emergency department between January 2013 and August 2018. Data on age, gender, diagnosis, insertion success rate and complications were collected and analysed.
Results:
Seventy-two patients were enrolled; of these 38 (52.8%) were male. The median age was 9 months (interquartile range: 3-34.5 months). Of the total, 22 (30.6%) received more than one IO insertion. Ninety-seven consecutive IO insertions were identified. The rate of successful insertions was achieved at 92.7% (90 insertions). There were 21 complications (21.6%), including 17 extravasations (17.5%) of fluid and four dermal abrasions (4.1%). We found no cases of complications that may have compromised patient safety.
Conclusions:
The success rate of the EZ-IO insertion was high in paediatric patients. However, we found a higher incidence of dermal abrasions, which might be a complication specific to children.
