Management of raised intracranial pressure in children
1Intensive Care Unit, Queen Alexandra Hospital, Portsmouth, Hampshire, UK.
Insights
Pediatric head injuries are common. Managing intracranial pressure (ICP) is crucial to limit secondary brain injury in children, with interventions tailored to individual responses.
Area of Science:
- Pediatric Neurology
- Critical Care Medicine
- Trauma Surgery
Background:
- Children experience frequent head injuries due to developmental factors and physical characteristics.
- Primary brain injury is irreversible, emphasizing the need to manage secondary insults.
- Elevated intracranial pressure (ICP) is a critical complication following pediatric head trauma.
Purpose of the Study:
- To review and categorize interventions for managing elevated ICP in pediatric head injuries.
- To provide a framework for optimizing patient care and minimizing secondary brain injury.
- To highlight the importance of individualized treatment strategies.
Main Methods:
- Literature review of pathophysiology and management of raised ICP in children.
- Categorization of interventions into first and second-tier treatments.
- Emphasis on monitoring ICP and maintaining adequate cerebral perfusion pressure.
Main Results:
- Understanding head injury pathophysiology aids in managing ICP.
- Key interventions include maintaining normovolaemia, appropriate positioning, mechanical ventilation, and drug therapy.
- Nursing interventions like reducing stimuli and avoiding clustered care are vital for ICP management.
Conclusions:
- ICP management is central to limiting secondary brain injury in pediatric head trauma.
- A tiered approach to interventions, tailored to the child's response, is essential.
- Optimizing ICP management requires a comprehensive understanding of both medical and nursing strategies.
Abstract:
Children suffer a significant number of head injuries as a result of their high activity levels, immature developmental skills and increased head-to-body mass ratio. Primary brain injury is irreversible, but secondary insults can be limited. Central to this is the management of raised intracranial pressure (ICP). The pathophysiology of head injury can explain some of the causes of raised ICP. Monitoring of ICP is important and this is closely linked to the maintenance of an adequate cerebral perfusion pressure and the importance of normovolaemia. Other interventions that have been shown to limit rises in ICP are appropriate use of positioning, mechanical ventilation and drug therapy. Less common therapies include jugular venous bulb oxygen saturation monitoring and the use of trometamol (THAM). Most nursing interventions do not actively reduce ICP, but they are central to its management. Reducing stimuli, avoiding cluster care, manual hyperinflation and limiting routine endotracheal suction may prevent an accumulative rise in ICP. Based on this literature review, it is possible to divide these interventions into first and second tier treatments, as shown in the protocol. Much of the suggested management will occur simultaneously, but it is important to assess the child's own response to each intervention and thus tailor treatment to minimize secondary brain injury.
