Pediatric Burn Management: Current Standards, Challenges, and Clinical Protocols

Circulation, Disability, Exposure—must be completed systematically.

Airway and Breathing:

• The pediatric airway is narrower and more prone to obstruction from relatively minimal edema. According to Poiseuille's law, a 50% decrease in airway radius results in a 16-fold increase in airway resistance, making prompt airway intervention critical.

• Early intubation should be strongly considered when there are signs of inhalation injury, facial burns, stridor, or respiratory distress.

• DO NOT delay intubation if severe inhalation injury or respiratory distress is present or anticipated—fluid resuscitation will exacerbate laryngeal swelling and increase intubation difficulty.

• In pediatric patients, airway compromise is the most common cause of severe morbidity and mortality, likely due to the small size of the airway. The threshold for intubation must be lower in pediatric patients due to the potential for rapid development of airway edema.

• If the child is not intubated, they must be observed in an area with continuous cardiorespiratory monitoring and staff trained to recognize evolving airway compromise, with intubation facilities immediately available.

• Consultant anesthetic/PICU staff must be informed of all upper airway burns.

Circulation:

• Obtain vascular access through unaffected skin. If peripheral access is difficult, intraosseous (IO) access should be obtained promptly.

• Hypotension is a late and ominous sign in pediatric burn patients; reliance must be placed on subtle signs including tachycardia, prolonged capillary refill time, lethargy, and decreased urine output.

Temperature Management:

• Maintain patient temperature >35°C. Children are at high risk for hypothermia during exposure and assessment.

3.2 Indications for Intubation in Pediatric Burns

Intubation decisions should be guided by a combination of the American Burn Association (ABA) Criteria and the Denver Criteria, with pediatric-specific modifications.

American Burn Association (ABA) Intubation Criteria:

Denver Criteria (Additions to ABA Criteria):

• Singed facial or nasal hair

• Suspected smoke inhalation

The Denver Criteria demonstrated increased sensitivity for predicting the need for long-term intubation (95%) compared to ABA criteria alone (77%).

Pediatric-Specific Intubation Indications:

Clinical signs mandating immediate intubation:

• Stridor, drooling, or hoarseness

• Facial or neck burns with evidence of airway involvement

• Increased work of breathing (accessory muscle use, sub- and suprasternal retractions)

• Decreased level of consciousness with loss of protective reflexes

• Oxygen saturation <94% in room air (note: normal saturations do NOT exclude inhalation injury as carboxyhemoglobin is misread as oxyhemoglobin by pulse oximeters)

• Carbonaceous sputum, soot in mouth/nares, or oral mucosal edema/ulceration

High-Risk Clinical Scenarios (Strongly Consider Early Intubation):

• Enclosed space fire exposure with suspected inhalation injury

• Death of persons at the scene (indicates high toxin exposure)

• Signs of upper airway edema—tongue swelling, facial edema, neck swelling

• Deep dermal and full-thickness facial burns

• Carboxyhemoglobin >5% on co-oximetry

• Intraoral burns or singed nasal hairs

Special Pediatric Considerations:

• "IF IN DOUBT, INTUBATE" —the pediatric airway becomes obstructed more rapidly than the adult airway

• Intubate prior to transfer if the child requires transport between hospitals and airway concerns exist

• Edema progresses rapidly and is worsened by fluid resuscitation—do NOT wait for deterioration

• Signs may be minimal at presentation but progress rapidly—continuous monitoring essential

Intubation Technique Recommendations:

3.3 Estimating Total Body Surface Area (TBSA)

Accurate TBSA estimation is critical for appropriate fluid resuscitation and triage decisions. The Lund-Browder chart is the preferred method for pediatric patients because it accounts for age-related changes in body proportions. Unlike the Rule of Nines, which is appropriate for adults, the Lund-Browder chart adjusts for the larger head and smaller lower extremities in children.

Key points for TBSA estimation:

• Only partial- and full-thickness burns are counted; superficial (first-degree) burns are excluded from TBSA calculations

• The palmar method—using the patient's palm (including fingers) from the wrist crease to fingertip—represents approximately 1% TBSA and is useful for smaller burns

• TBSA estimation should ideally be performed after initial debridement

Modified Lund-Browder Chart Values (%TBSA per body part) :

3.4 Criteria for Transfer to a Certified Pediatric Burn Center

The American Burn Association (ABA) provides clear criteria for transfer to a specialized burn center. Transfer is recommended for:

• Partial-thickness burns >10% TBSA in children

• Full-thickness burns of any size

• Burns involving the face, hands, feet, genitalia, perineum, or major joints

• Electrical burns or lightning strikes

• Chemical burns

• Inhalation injury

• Burns with concomitant trauma where the burn poses the greatest mortality risk

• Children in hospitals without qualified personnel or equipment for pediatric burn care

• Suspected non-accidental trauma or patients requiring specialized social/rehabilitative intervention
