Abstract
Neurological assessment of patients with burn injuries may be complicated by a variety of factors including artificial ventilation and sedation, cerebral hypoxia and intoxication. Medically unstable intubated patients present logistical challenges for radiological imaging. The role of neuroimaging as an adjunct to clinical assessment of burn injured patients has not yet been determined. This study aims to investigate the indications, findings and outcomes of neuroimaging studies performed for burn injured patients. A retrospective case series study of adult burn patients admitted over an 8 year period was completed in the National Burns Centre at St James's Hospital, Dublin. Neuroimaging studies carried out for patients admitted during the study period were reviewed by a Consultant Radiologist and Consultant Stroke Physician. Outcomes included neuroimaging findings, prevalence of white matter disease (Fazekas scale), length of stay, discharge destination, predicted and observed mortality. 1328 consecutive patients with burn injuries were admitted during the study period. 56 patients underwent neuroimaging studies with computerised tomography, magnetic resonance imaging or both. 46 out of 56 neuroimaged patients (82.1%) had significant radiological findings, including 14 patients (25%) with acute findings. There was a high prevalence of white matter disease (mean total Fazekas score: 3.59) and acute cerebral infarction (7 patients). Patients with radiological findings required additional in-patient rehabilitation and had increased length of stay (Median 47.0 days vs. 27.5 days, p < 0.027). Patients with resuscitation burns or associated inhalation injury were significantly more likely to undergo neuroimaging (p < 0.0001) and to have positive radiological findings. Predicted mortality was higher in patients with positive neuroimaging findings compared to patients with normal neuroimaging studies, although there was no significant difference in observed mortality between these two groups. Neuroimaging is used appropriately in patients admitted with burns and provides valuable applicable clinical information when indicated.
