Insights

Prolonged nontraumatic coma in children can lead to significant long-term issues. Anoxia, assisted ventilation, elevated intracranial pressure, and deep coma duration are key indicators of poor outcomes.

Area of Science:

  • Pediatric Neurology
  • Neurocritical Care

Background:

  • Prolonged nontraumatic coma in children presents complex challenges for clinical decision-making and parental counseling.
  • Understanding prognostic indicators is crucial for managing these critical cases.

Purpose of the Study:

  • To identify clinical parameters predicting outcomes in children with prolonged nontraumatic coma.
  • To aid in clinical decision-making and parental guidance.

Main Methods:

  • Retrospective review of 16 children with prolonged nontraumatic coma ( > 5 days).
  • Clinical and neurological examinations, and school reports assessed 1-5 years post-coma.
  • Etiology of coma, need for ventilation, intracranial pressure, and coma depth were analyzed.

Main Results:

  • Outcomes varied: 6 children normal, 6 with minor handicaps, 4 with major sequelae.
  • Anoxia and need for assisted ventilation correlated with poorer outcomes.
  • Elevated intracranial pressure (> 2 days) and deep coma (> 2 weeks) indicated abnormal outcomes.

Conclusions:

  • Specific clinical parameters like anoxia, elevated intracranial pressure, and coma duration predict long-term outcomes in pediatric non-traumatic coma.
  • Standardized assessment criteria are needed for better management and evaluation of these children.
  • Further research is warranted given improving care capabilities but limited experience.

Traumatic Brain Injury l: Introduction

DefinitionTraumatic brain injury, or TBI, is a disturbance of normal brain function induced by an external mechanical force, such as a direct blow to the head or a penetrating injury. It can affect both brain structure and function, producing a wide range of clinical outcomes. TBI is a heterogeneous condition, meaning its effects may differ based on the type, location, and severity of the injury.Basis of ClassificationTBI is classified based on severity, injury mechanism, or pathophysiology. In...

Increased Intracranial Pressure l: Introduction

Intracranial hypertension is a sustained elevation of intracranial pressure (ICP) above 22 mm Hg. In supine adults, normal ICP is ~7–15 mm Hg.The rigid, nonexpandable cranium contains three components—brain tissue, blood, and cerebrospinal fluid (CSF)—that total ~1,700 mL in a typical adult: 1,400 mL brain (~80%), 150 mL blood (~10%), and 150 mL CSF (~10%). According to the Monro–Kellie doctrine, total intracranial volume is effectively fixed. When one component expands, CSF and venous blood...

Increased Intracranial Pressure ll: Pathophysiology

Increased intracranial pressure (ICP) refers to a potentially life-threatening rise in pressure inside the skull. This usually happens when there is a major change in the volume of brain tissue, blood, or cerebrospinal fluid (CSF) — the three components inside the skull. According to the Monro-Kellie doctrine, if the volume of one component increases, the volumes of the other components must decrease to maintain normal pressure. If this does not happen, ICP rises.The process often begins with...
Cerebral Edema ll: Pathophysiology01:22

Cerebral Edema ll: Pathophysiology

Vasogenic edema is a major form of cerebral edema characterized by abnormal accumulation of fluid in the brain’s extracellular space due to disruption of the blood–brain barrier (BBB). The BBB is a specialized structure composed of endothelial cells connected by tight junctions, supported by astrocytic endfeet and a basement membrane. Under normal conditions, it tightly regulates the movement of ions, proteins, and solutes between the bloodstream and brain parenchyma. When this barrier loses...

Seizures l: Introduction

Understanding seizures and epilepsy relies on key definitions that help in recognizing, classifying, and managing these disorders. These definitions provide a framework for recognizing, classifying, and managing seizure disorders.DefinitionsA seizure is a sudden, abnormal burst of electrical activity in the brain that can cause changes in awareness, movement, sensation, or behavior, depending on the area involved. Epilepsy is a chronic condition characterized by recurrent, unprovoked seizures,...

Secondary Spinal Cord Injury llI: Pathophysiology

Early Ischemia and Ionic ImbalanceWithin minutes of spinal cord injury, a secondary cascade begins, progressing over hours to weeks. Vascular damage reduces blood flow, causing ischemia and mitochondrial dysfunction. ATP depletion leads to ion pump failure, membrane depolarization, sodium influx, potassium efflux, and water accumulation, resulting in cellular swelling. Increased intracellular calcium further disrupts mitochondria and accelerates cellular injury.Excitotoxicity and Neuronal...
