Drug extravasation during EZ-IO use in pediatric patients
Abstract:
Background: The semi-automatic intraosseous device (EZ-IO®) is useful for safely securing intraosseous access. There are some complications associated with its use but few studies have examined the risk factors. The present study aimed to investigate the risk factors for extravasation as a complication of EZ-IO use in pediatric patients.
Methods: This study is a secondary analysis of a previous, monocentric, retrospective study conducted in Japan describing the use of EZ-IO in a pediatric emergency department. The patients included in the study were younger than 16 years of age with EZ-IO use at the Tokyo Metropolitan Children’s Medical Center between January, 2013 and August, 2018. The factors analyzed included demographic information (sex, age, weight), Glasgow Coma Scale (GCS), diagnosis, bolus infusion, and lidocaine use. The primary endpoint was the odds ratio (OR) and 95% confidence interval (CI) for extravasation incidence.
Results: Seventy-two patients were enrolled; 14 of these had extravasation, 39 (54.2%) had a diagnosis of cardiac arrest, and 50 (69.4%) had a GCS score of 8 or less. Statistical analysis demonstrated that the group with a high GCS score was significantly associated with extravasation: GCS (<13) versus GCS (13≦) (OR: 12.25; 95% CI: 2.54-59.15; p < 0.01), GCS (<8) versus GCS (8≦) (OR: 4.78; 95% CI: 1.34-17.01; p = 0.03).
Conclusions: A high GCS score was associated with extravasation in EZ-IO use significantly more often than a low GCS score. No significant difference was found in the other endpoints.
