Background:
Neurological injury is common in neonates undergoing cardiac surgery with cardiopulmonary bypass, yet perioperative neuroimaging and neuromonitoring practices vary across centres. We aimed to characterise current practices and provider perceptions across Pediatric Cardiac Intensive Care Society-affiliated centres.
Methods:
We conducted an online, cross-sectional survey of Pediatric Cardiac Intensive Care Society members between August and October 2024. Part 1, completed by medical directors, assessed institutional characteristics and perioperative practices. Part 2, completed by multidisciplinary providers, evaluated perceptions of utility and sufficiency.
Results:
A total of 143 responses from 60 institutions were analysed, including 38 medical directors. Most centres had a dedicated cardiac ICU (87%) and were academically affiliated (76%). Routine neuroimaging was more common preoperatively than postoperatively (87% vs. 32%), with head ultrasound most frequently used. Near-infrared spectroscopy was the most common neuromonitoring modality, while routine electroencephalography was reported at 18% of centres preoperatively and 50% postoperatively. Physicians were more likely than advanced practice providers and nurses to report practices as sufficient. Neurocritical care teams were present at 42% of centres but were not associated with greater use of neuroimaging or monitoring.
Conclusions:
Significant variability exists in perioperative practices and provider perceptions, highlighting the need for multidisciplinary alignment and standardised guidelines.
