Assessing the Impact of 3% Hypertonic Saline Hyperosmolar Therapy on Intubated Children With Isolated Traumatic Brain Injury by Cerebral Oximetry in a Pediatric Emergency Setting.

Background: Intubated pediatric patients with isolated traumatic brain injury (TBI) are a diagnostic challenge for early detection of altered cerebral physiology instigated by trauma-induced increased intracranial pressure (ICP) while preventing secondary neuronal damage (secondary insult detection) and assessing the effects of increased ICP therapeutic interventions (3% hypertonic saline [HTS]). Invasive brain tissue oxygen monitoring is guiding new intensive care unit TBI management but is not pediatric emergency department (PED) readily accessible. Objective measurements on pediatric isolated TBI-altered bihemispheric cerebral physiology and treatment effects of 3% HTS are currently lacking.

Predicting Hemolytic Uremic Syndrome and Renal Replacement Therapy in Shiga Toxin-producing Escherichia coli-infected Children.

Methods: We conducted a multicenter, historical cohort study to identify features associated with development of HUS (primary outcome) and need for renal replacement therapy (RRT) (secondary outcome) in STEC-infected children without HUS at initial presentation.

Bihemispheric Cerebral Oximetry Monitoring's Functionality in Suspected Cerebral Edema Diabetic Ketoacidosis With Therapeutic 3% Hyperosmolar Therapy in a Pediatric Emergency Department.

Background: Suspected cerebral edema diabetic ketoacidosis (SCEDKA) is more common than perceived with symptoms including altered mentation, headache with vomiting, depressed Glasgow coma scale (GCS), abnormal motor or verbal responses, combativeness, and neurological depression. Suspected cerebral edema diabetic ketoacidosis has been associated with initial diabetic ketoacidosis (DKA) presentation and at start of DKA therapy.Cerebral oximetry (bihemispheric regional cerebral oxygen saturation [rcSO2] and cerebral blood volume index [CBVI]) can detect increased intracranial pressure (ICP)-induced altered bihemispheric cerebral physiology (rcSO2) (Crit Care Med 2006;34:2217-2223, J Pediatr 2013;163: 1111-1116, Curr Med Chem 2009;16:94-112, Diabetologia 1985;28:739-742, Pediatr Crit Care Med 2013;14:694-700).

An Update on End-Tidal CO2 Monitoring.

End-tidal CO2 (ETCO2) monitoring is not a new modality in the pediatric emergency department (PED) and emergency department. It is the standard of care during certain procedures such as intubations and sedations and can be used in variety of clinical situations. However, ETCO2 may be underused in the PED setting.

An Update on Pediatric Stroke Protocol.

Pediatric stroke is relatively rare, with approximately 1000 childhood strokes in the United States per year. However, the occurrence of stroke in children leads to significant morbidity and mortality, warranting the development proven screening tools, protocols, and treatment options. Because significant delays in seeking medical attention can occur, time to recognition of pediatric stroke in the emergency department is uniquely challenging and critical.

Hemispheric Cerebral Oximetry Monitoring During Pediatric Seizure Activity in a Pediatric Emergency Department.

Background: Sustained neuronal activity during seizures causes cellular perturbations, alterations in cerebral physiology, and potentially neurological injury, a neurological emergency. With variable clinical manifestations of seizures, frequent failure of seizure recognition by providers in pediatric and developmentally challenged patients can increase seizure complications. Neuroresuscitation should include rapid cerebral physiology assessment for increased seizure recognition and optimal neurological outcomes.

Management of Croup in the Emergency Department: The Role of Multidose Nebulized Epinephrine.

Objectives: Croup occasionally requires medical intervention for respiratory distress. Mainstays of treatment are corticosteroids and nebulized epinephrine. Diagnosis and assessment of severity remain clinical.

Cerebral oximetry with blood volume index and capnography in intubated and hyperventilated patients.

Objective: Hyperventilation-induced hypocapnia leads to cerebral vasoconstriction and hypoperfusion. Intubated patients are often inadvertently hyperventilated during resuscitations, causing theoretical risk for ischemic brain injury. Current emergency department monitoring systems do not detect these changes.

Newborn Screening: What Does the Emergency Physician Need to Know?

Newborn screening programs were established in the United States in the early 1960s. Newborn screening programs were then developed by states and have continued to be the responsibility of the state. All states require a newborn screening, but what is required of these programs and screening panels has differed greatly by state.

Cerebral oximetry with cerebral blood volume index in detecting pediatric stroke in a pediatric ED.

Background: Despite pediatric stroke awareness and pediatric stroke activation systems, recognition and imaging delays along with activation inconsistency still occur. Reliable objective pediatric stroke detection tools are needed to improve detection and activations. Regional cerebral oxygen saturation (rcso2) with cerebral blood volume index (CBVI) can detect abnormal cerebral physiology.

Pediatric Acute Stroke Protocol Activation in a Children's Hospital Emergency Department.

Background And Purpose: Pediatric acute stroke teams are a new phenomenon. We sought to characterize the final diagnoses of children with brain attacks in the emergency department where the pediatric acute stroke protocol was activated and to describe the time to neurological evaluation and neuroimaging.

Methods: Clinical and demographic information was obtained from a quality improvement database and medical records for consecutive patients (age, ≤20 years) presenting to a single institution's pediatric emergency department where the acute stroke protocol was activated between April 2011 and October 2014.
