Management of neonatal head injuries: A retrospective cohort study

Aim: The aim of this study is to describe circumstances, management and short-term outcomes of neonatal head trauma, and adherence to the Paediatric Emergency Care Applied Research Network (PECARN) head trauma prediction rule for children under 2 years. Methods: Multicentre retrospective cohort study of neonates (<29 days) with head trauma across 25 emergency departments (ED) from January 2017 to June 2021. Results: A total of 492 neonates (median age 17 days, range 0-28 days) with non-trivial head trauma were enrolled. Falls were the most common injury mechanism (375/492, 76.2%). Imaging was performed in 150/492 (30.5%) neonates. Clinically important traumatic brain injury (ciTBI), defined as death, neurosurgery, prolonged intubation, or extended hospitalisation from injury, occurred in 7/492 (1.4%) cases. Notably, 286/492 (58.1%) neonates were managed by short-term observation (<48 h), and 126/492 (25.6%) were admitted. Among high-risk neonates per PECARN criteria, 17/21 (80.9%) did not undergo recommended head CT scans but were observed within ED short observation units or underwent alternative imaging, with no ciTBI diagnoses among those discharged without CT. Conclusion: Severe neonatal head injuries are rare, and most neonatal head injuries have a favourable outcome, making observation a suitable approach, while remaining vigilant for signs of non-accidental injuries.
