Study Notes

Traumatic Brain Injury (TBI)

TBI is the leading cause of death (60%-70%) and long-term disability resulting from trauma in all ages.
Maintaining systemic blood pressure (SBP) is critical; children with SBP less than 90 mm Hg have three times higher mortality.
Over 90% of children present with SBP above 90 mm Hg.

Child Abuse and Trauma

Over 3 million child abuse reports filed annually in the U.S.; actual cases may be higher.
Distinction necessary between accidental trauma (e.g., forearm fractures, playground falls) and intentional injuries that raise suspicion for abuse (e.g., rib fractures, skull fractures).
Majority of child abuse fatalities occur in children aged 3 and younger.

Hypotension and Blood Loss in Children

Hypotension due to hypovolemia in children indicates potential cardiovascular collapse.
Children can maintain blood pressure longer than adults after blood loss; tachycardia is an early indicator of blood loss.
Hypotension typically does not manifest until 25% of blood volume is lost; children have a typical blood volume of 80 mL/kg.

Coagulopathy and Massive Transfusion

Massive transfusion can cause coagulopathy due to dilution of clotting factors; hypothermia complicates clotting ability.
Massive blood loss typically results from solid organ injuries; massive exsanguination is uncommon.

Pediatric Trauma Statistics

Trauma is the leading cause of death in children over 1 year, primarily from motor vehicle accidents, followed by falls and child abuse.
Drowning ranks second in injury-related deaths among children; more prevalent in males and typically happens close to home.

Burns in Children

Scalds account for 60%-70% of pediatric burns; contact burns follow at 20%.
Intentional scald burns can be suspected with inconsistent injury stories or specific burn characteristics.
Effective prevention strategies include educating families about kitchen safety and water heater temperatures.

Pain Management in Burn Patients

Pain management is crucial due to the frequency of painful procedures (e.g., dressing changes, debridement).
Partial-thickness burns are generally more painful than full-thickness burns due to intact nerve endings.
Methadone and ketamine can be effective in managing burn-associated hyperalgesia.

Hypermetabolic State after Burns

Burn injuries lead to a hypermetabolic state, particularly in patients with burns covering 60% or more of total body surface area (TBSA).
Acute phase lasts 48 hours post-injury, marked by hypovolemia and protein loss; hypermetabolic phase follows.
Increased metabolic rate involves elevated catecholamines, glucagon, and glucocorticoids which impact healing negatively.

Fluid Resuscitation and Burn Management

Parkland formula estimates fluid needs post-burn, guiding administration of crystalloids.
Over-resuscitation can occur; urine output should be monitored to ensure adequate organ perfusion.

Trauma Assessment Tools

Glasgow Coma Scale (GCS) of 8 or less necessitates intubation due to compromised neurologic status.
True inhalational injuries can carry high morbidity and mortality, particularly in enclosed spaces.
Endotracheal intubation should be considered in cases of significant burn surface area or suspected inhalational injury.

Specific Trauma Considerations

Tension pneumothorax risk is higher in children, requiring prompt needle decompression in certain situations.
Eschar formation over burned skin can compromise vascularity and lead to respiratory complications.

Additional Considerations

Carbon monoxide poisoning may present as falsely elevated pulse oximetry readings and requires specific detection methods (co-oximetry).
Cyanide exposure may occur with combustion, leading to lactic acidosis; sodium thiosulfate can be a treatment option.
Pediatric patients need specialized protocols for injuries due to unique anatomical and physiological differences.### Patient Care and Nutritional Support
Environmental temperatures between 28°C and 33°C can lower caloric demands in patients.
Proper covering during transport, along with analgesics and anxiolytics, contributes to reduced energy needs.

Importance of Enteral Feeding

Enteral feeding is essential for:
- Promoting good nutrition.
- Maintaining gastrointestinal (GI) motility.
- Protecting mucosal integrity to minimize infection and sepsis risk.
- Reducing the incidence of stress ulcers.

Feeding Tube Preferences

Postpyloric feeding tubes are preferred for continuous feeding, particularly in burn patients, to effectively meet caloric needs and provide additional enteral feeding benefits.

Parenteral Feeding Considerations

Parenteral feeding is a viable option but does not maintain the mucosal barrier of the gut.
Increased risk of bacterial translocation and infection is associated with parenteral feeding methods.

Protein Requirements After Burns

Children recovering from burns require approximately 3 grams of protein per kilogram of body weight per day.

Hypothermia Classification

Hypothermia severity is categorized by core body temperature:
- Mild: 34°C to 36°C
- Moderate: 30°C to 34°C
- Severe: Below 30°C
