Which STAT categories include the sickest children, specifically those with life-threatening conditions?

STAT Categories for the Sickest Children

The sickest children are those with life-threatening features, which are categorized as high-risk in STAT categories, requiring immediate intervention due to imminent risk of death.

High Risk STAT Category: Immediate Risk of Dying

Children in this category require urgent supportive treatment due to:

• Depressed conscious level (any degree) 1
• Active seizure activity 1
• Irregular respirations or obstructed airway (pooling saliva or vomit in mouth) 1
• Hypoxia (oxygen saturations < 95%) 1
• Evidence of shock (systolic blood pressure < 80 mm Hg or < 70 mm Hg if patient aged < 1 year) or two or more of the following: tachycardia, increased work of breathing, cool peripheries, capillary refill time ≥ 3 seconds, temperature gradient 1
• Clinical evidence of dehydration 1
• Hypoglycemia < 3 mmol/l 1
• Metabolic acidosis (base deficit > 8 mmol/l) 1
• Severe hyperkalemia (potassium > 5.5 mmol/l) 1

Life-Threatening Features in Specific Conditions

Severe Asthma

• Too breathless to talk or feed 1
• Respirations >50 breaths/min 1
• Pulse >140 beats/min 1
• PEF <33% predicted or best 1
• Poor respiratory effort 1
• Cyanosis, silent chest, fatigue or exhaustion 1
• Agitation or reduced level of consciousness 1

Cardiac Arrest

Children with cardiac arrest require immediate transfer to intensive care accompanied by a doctor prepared to intubate if there is:

• Deteriorating PEF, worsening or persisting hypoxia, feeble respirations, confusion, or drowsiness 1
• Exhaustion, coma or respiratory arrest 1
• Persistent hypoxia or hypercapnia 1

Intermediate Risk STAT Category

These children need high dependency care due to:

• Hemoglobin < 100 g/l 1
• History of convulsions during current illness 1
• Hyperparasitemia > 5% 1
• Visible jaundice 1
• Plasmodium falciparum in a child with sickle cell disease 1

Critical Illness Patterns by Age Group

Different age groups show distinct patterns of critical illness requiring intensive care:

• Neonates and young children: Complications from the perinatal period and respiratory system diseases (42.5%) 2
• School-aged children: Respiratory system diseases (38.5%) 2
• Adolescents: Accidental injuries and poisoning (47.9%) 2

Outcomes Based on Initial Presentation

The initial presentation significantly impacts survival outcomes:

• Children with pulseless electrical activity or ventricular fibrillation have higher successful CPR rates than those with asystole 2
• Most pediatric out-of-hospital cardiac arrests present with asystole or pulseless electrical activity (93.5%) 3
• Only 34.9% of pediatric out-of-hospital cardiac arrest patients achieve return of spontaneous circulation 3
• Only 4.6% of pediatric out-of-hospital cardiac arrest patients have favorable neurological outcomes 3

Important Considerations for Management

For Septic Shock

• Administration of an initial fluid bolus of 20 mL/kg is reasonable for infants and children with shock, including those with severe sepsis 1
• However, in settings with limited access to critical care resources (mechanical ventilation and inotropic support), bolus intravenous fluids should be administered with extreme caution as they may be harmful 1
• Reassessment after every fluid bolus is essential 1

For Respiratory Failure

• Respiratory distress syndrome in neonates, bacterial pneumonia, and status epilepticus are the most common causes requiring ICU admission 2
• Children with severe respiratory failure may require intubation and mechanical ventilation 4

Hospital Factors Affecting Mortality

The type of hospital where critically ill children receive care impacts mortality:

• Teaching hospitals (43% lower odds of mortality) 5
• Trauma centers (24% lower odds of mortality) 5
• Urban hospitals (22% lower odds of mortality) 5

Common Pitfalls in Management

• Failure to recognize early signs of deterioration before overt cardiorespiratory failure 1
• Delayed transfer to intensive care for children with deteriorating condition 1
• Inadequate monitoring of response to treatment (oxygen saturation, vital signs, level of consciousness) 1
• Inappropriate fluid management in specific contexts (such as severe febrile illness in resource-limited settings) 1
• Failure to consider the specific needs of children with underlying chronic conditions 2
