ReviewPediatric neurocritical care in the 21st century: from empiricism to evidence.
Approximately one in five children admitted to a pediatric ICU have a new central nervous system injury or a neurological complication of their critical illness. The spectrum of neurologic insults in children is diverse and clinical practice is largely empirical, as few randomized, controlled trials have been reported. This lack of data poses a substantial challenge to the practice of pediatric neurocritical care (PNCC). PNCC has emerged as a novel subspecialty, and its presence is expanding within tertiary care centers. This review highlights the recent advances in the field, with a focus on traumatic brain injury (TBI), cardiac arrest, and stroke as disease models. ⋯ There is an unmet need for clinicians with expertise in the practice of brain-directed critical care for children. Although much of the practice of PNCC may remain empiric, a focus on the regionalization of care, creating defined training paths, practice within multidisciplinary teams, protocol-directed care, and improved measures of long-term outcome to quantify the impact of such care can provide evidence to direct the maturation of this field.

Combined central diabetes insipidus and cerebral salt wasting syndrome after traumatic brain injury (TBI) is rare, is characterized by massive polyuria leading to severe water and electrolyte disturbances, and usually is associated with very high mortality mainly as a result of delayed diagnosis and improper management. ⋯ For combined diabetes insipidus and cerebral salt wasting syndrome after traumatic brain injury, massive polyuria is a major typical presentation, and intensive monitoring of fluid and sodium status is key for timely diagnosis. To achieve a favorable outcome, proper sodium chloride supplementation and cortisone acetate and vasopressin coadministration are key.

Sports-related concussion is a change in brain function following a direct or an indirect force to the head, identified in awake individuals and accounting for a considerable proportion of mild traumatic brain injury. Although the neurological signs and symptoms of concussion can be subtle and transient, there can be persistent sequelae, such as impaired attention and balance, that make affected patients particularly vulnerable to further injury. ⋯ In this paper, the authors review the available screening tools for concussion, with particular emphasis on the role of visual function testing. In particular, they discuss the oculomotor assessment tools that are being investigated in the setting of concussion screening.

Critical illness is a major cause of morbidity and mortality around the world. While obesity is often detrimental in the context of trauma, it is paradoxically associated with improved outcomes in some septic patients. The reasons for these disparate outcomes are not well understood. ⋯ Not only do experimental variables need to be matched as closely as possible to clinical scenarios, but animal models with pre-existing comorbid conditions need to be studied. This review briefly summarizes animal models of hemorrhage, blunt trauma, traumatic brain injury, and sepsis. It also discusses what has been learned through the use of obese models to study the pathophysiology of critical illness in light of what has been demonstrated in the clinical literature.

To evaluate whether indices of preinjury health and functioning are associated with risk of incident traumatic brain injury (TBI) with loss of consciousness (LOC) and to evaluate health-related factors associated with mortality in individuals with incident TBI. ⋯ Indices of health, mood, and functional status predict incident TBI with LOC in older adults. These findings may have implications for injury prevention and postinjury clinical management.
