Overview

Definition:
-Nonaccidental burns, also known as inflicted burns or child abuse burns, refer to thermal injuries intentionally caused by a caregiver or another individual on a child
-These injuries often deviate from accidental burns in their pattern, severity, and distribution, requiring astute recognition by healthcare professionals.
Epidemiology:
-Nonaccidental burns represent a significant proportion of abusive injuries in children, with incidence varying by region and reporting mechanisms
-Children under 5 years are particularly vulnerable
-Boys and girls are affected with similar frequency
-Recurrent abuse leading to burns can occur.
Clinical Significance:
-Recognizing nonaccidental burns is critical for preventing further harm to the child and for timely intervention and legal reporting
-Missed diagnosis can lead to continued abuse, severe morbidity, and mortality
-Understanding characteristic patterns aids in distinguishing inflicted injuries from accidental ones.

Clinical Presentation

History Points:
-Inconsistent history provided by caregiver
-Delayed presentation to healthcare
-History of frequent injuries or accidents
-Lack of adequate explanation for burn severity
-Caregiver anxiety or defensiveness
-Recurrent injuries reported by family or school.
Burn Characteristics:
-Uniform depth burns
-Sparing of flexural surfaces
-Glove or stocking distribution burns
-Sharply demarcated margins
-Burns in unusual locations (e.g., buttocks, genitalia, soles of feet)
-Multiple burns of different ages
-Immersion burns (e.g., partial or fully symmetrical, with clear water lines)
-Cigar or cigarette burns (small, discrete, punched-out lesions)
-Patterned injuries (e.g., from objects like irons or heating elements).
Associated Findings:
-Bruising
-Lacerations
-Fractures
-Head trauma
-Signs of malnutrition or neglect
-Behavioral changes (e.g., fearfulness, withdrawal, aggression)
-Delay in seeking medical attention.

Diagnostic Approach

History Taking Details:
-Obtain a detailed history of the injury, including mechanism, time of onset, initial management, and witness accounts
-Corroborate the history with the child’s statements (if age-appropriate) and caregiver’s account
-Inquire about any previous injuries or hospital visits
-Assess the family environment and caregiver's mental state.
Physical Examination:
-Perform a thorough head-to-toe examination, documenting all injuries, including burns, bruises, abrasions, and skeletal abnormalities
-Pay close attention to the distribution, depth, and shape of burns
-Document vital signs and overall child's condition
-Assess for signs of dehydration or systemic complications.
Investigations:
-Complete blood count (CBC)
-Blood chemistry profile (electrolytes, renal function tests, liver function tests)
-Coagulation profile
-Blood type and screen
-Wound cultures if infection is suspected
-Skeletal survey (radiographs of the entire skeleton) to detect associated fractures, especially in young children
-CT scan or MRI of the head if head injury is suspected
-Photographic documentation of all injuries with scale.
Differential Diagnosis:
-Accidental scalds (e.g., hot liquids, bath water)
-Accidental contact burns (e.g., hot stoves, radiators, curling irons)
-Electrical burns (entry and exit wounds, internal damage)
-Chemical burns
-Seizures with burns
-Autoinflicted burns (rare in young children)
-Certain skin conditions mimicking burns (e.g., epidermolysis bullosa, Stevens-Johnson syndrome)
-Congenital insensitivity to pain.

Management Principles

Initial Stabilization:
-Airway, breathing, circulation (ABC)
-Fluid resuscitation using Parkland formula (e.g., 4 mL x % TBSA burned x kg body weight in 24 hours, with half given in first 8 hours)
-Pain management with intravenous opioids
-Tetanus prophylaxis
-Maintain normothermia.
Wound Care:
-Cooling the burn area with room-temperature water
-Gentle cleaning of the wound
-Application of sterile dressings with topical antimicrobial agents (e.g., silver sulfadiazine, mafenide acetate, bacitracin)
-Debridement of necrotic tissue
-Burn unit referral for significant burns.
Nutritional Support:
-High-calorie, high-protein diet to meet hypermetabolic demands
-Enteral feeding (nasogastric or orogastric tube) if oral intake is insufficient
-Monitor nutritional status closely.
Multidisciplinary Approach:
-Involve a multidisciplinary team: pediatricians, pediatric surgeons, burn specialists, social workers, child protection services, law enforcement, psychologists, and child life specialists
-Coordinate care and reporting.

Key Points

Exam Focus:
-Recognize classic burn patterns suggestive of abuse
-Understand the importance of history-burn discrepancy
-Know mandatory reporting laws and procedures
-Differentiate accidental from inflicted burns based on shape, depth, and location.
Clinical Pearls:
-Always consider nonaccidental injury when burns are uniform, patterned, or in unusual locations
-A delayed presentation with a vague history should raise suspicion
-The absence of a credible explanation for the injury is a critical red flag
-Document everything meticulously, especially photographic evidence.
Common Mistakes:
-Accepting a caregiver's inconsistent history without further investigation
-Failing to perform a complete physical examination including a skeletal survey
-Not documenting findings thoroughly, especially photographic evidence
-Delaying reporting to child protective services.
