Mortality And Morbidity of Severe Traumatic Brain Injuries; A Pediatric Intensive Care Unit Experience Over 15 Years

Abstract

Objective: To determine the mortality, morbidity, types of intracranial hemorrhages, and factors associated with length of stay (LOS) associated with accidental traumatic brain injury (TBI) at a pediatric intensive care unit (PICU) of a regional trauma center in an Asian city. Methods: This study is a retrospective review of types of head injury, mortality and morbidity demographics of patients admitted to a PICU with TBI. All patients with accidental TBI were included, namely road traffic injury (RTI) and fall, and their demographics compared. Non-accidental injuries (NAI) were excluded. Results: 95 children (78% males) were admitted to a PICU with RTI or falls from 2002 to 2017. They accounted for 3.7% of PICU admissions. Comparing with falls, victims of RTI were older (p<0.001) and more likely to suffer from skull fracture (p=0.017). There were 4 deaths with falls (6.8%) but none with RTI. Subarachnoid hemorrhages, extradural hemorrhages, the use of mechanical ventilation, inotropes and neurological supports were associated with longer LOS in PICU in these injuries (p<0.001). Conclusion: A longer PICU LOS is associated with extradural and subarachnoid hemorrhages, usage of inotropes, mechanical ventilation and neurological supports in falls and RTI. Three-quarters of victims are males. Preventive health education should be especially directed to boys to reduce severe TBI in this Asian city.
