Pediatric and Geriatric Trauma Considerations

Why Age Changes Everything in Trauma

Trauma is the leading cause of death and disability across all age groups, but the same mechanism—a car crash, a fall, a bicycle accident—can produce very different injuries and very different assessment findings depending on whether your patient is a toddler or an 80-year-old. Anatomical and physiological differences between pediatric and geriatric patients alter where injuries occur, how the body compensates, how quickly decompensation happens, and which interventions take priority. Recognizing these differences is not optional; it is a core patient-safety skill.

Pediatric Trauma Considerations

Anatomy that changes injury patterns

Children are not small adults. Several structural features concentrate injury risk in ways that differ from adults.

• Larger head-to-body ratio. A young child's head is proportionally much larger and heavier relative to body size than an adult's. In blunt trauma and falls, the head leads, making traumatic brain injury (TBI) the most common cause of pediatric trauma death. The neck muscles are weaker and cannot absorb energy as effectively, increasing cervical spine vulnerability even when plain radiographs look normal—a phenomenon sometimes called SCIWORA (spinal cord injury without radiographic abnormality).
• Compliant chest wall. A child's ribs are more cartilaginous and flexible. Energy from blunt chest trauma transmits directly to underlying organs—lungs, heart, great vessels—without necessarily fracturing ribs. Absence of rib fractures does not rule out serious thoracic injury in a child.
• Solid organs are relatively larger and less protected. The liver and spleen extend below the rib cage and are more exposed. Lap-belt injuries frequently produce a triad of abdominal wall bruising, intestinal injury, and lumbar spine fracture (the "lap-belt complex").
• Larger body-surface-area-to-mass ratio. Children lose heat rapidly. Hypothermia worsens coagulopathy and shock; keep pediatric trauma patients warm.

Physiology and vital signs

Normal vital signs in children are age-dependent. Tachycardia and elevated respiratory rates are normal at young ages but become confusing in the trauma context—early shock may look like a "normal" child to an untrained eye. Children have significant cardiovascular reserve and can maintain near-normal blood pressure until 25–30% of blood volume is lost, then decompensate rapidly. Do not wait for hypotension to suspect serious hemorrhage.

The Broselow tape is the standard field tool for estimating weight-based equipment sizes and medication doses when you cannot obtain an accurate weight. The patient is measured supine from the top of the head to the heel; the color-coded zone indicates appropriate equipment sizes and approximate weight.

Assessment priority reminders

• Use a structured pediatric approach (such as the Pediatric Assessment Triangle) on first contact.
• Reassess frequently; children can deteriorate suddenly.
• Involve caregivers to reduce anxiety and gather history, but keep your clinical focus.

Geriatric Trauma Considerations

Anatomy and physiology that increase risk

The geriatric population sustains injury from lower-energy mechanisms because the aging body is less resilient.

• Osteoporosis. Decreased bone mineral density means fractures occur with minor falls or forces that would not injure younger adults. Hip fractures from ground-level falls, vertebral compression fractures, and rib fractures are common and carry significant morbidity and mortality.
• Diminished physiologic reserve. Maximum heart rate, cardiac output, pulmonary function, and renal reserve all decline with age. The elderly patient has a narrower margin to compensate for blood loss or hypoxia. Tachycardia may be blunted by age or medication (beta-blockers), masking the usual shock response.
• Medications alter assessment and treatment. Anticoagulants (warfarin, direct oral anticoagulants) increase bleeding risk and can turn minor head trauma into life-threatening intracranial hemorrhage. Beta-blockers prevent the expected tachycardic response to shock. Multiple medications increase fall risk and complicate management.
• Cervical spine degeneration. Conditions such as osteoarthritis and spinal stenosis increase the risk of cervical spine fracture and spinal cord injury even from low-energy mechanisms such as a ground-level fall.
• Skin and tissue fragility. Thinner skin tears easily; elderly patients develop pressure injuries quickly during prolonged extrication.

Assessment pitfalls

• Normal vital signs may not be normal. An elderly hypertensive patient with a "normal" blood pressure of 110/70 may actually be in relative hypotension compared with their baseline.
• Obtain a medication list whenever possible—it is as important as the mechanism of injury.
• Cognitive baseline matters. Altered mental status may reflect TBI, hypoxia, shock, or pre-existing dementia. Establish baseline from family or caregivers.

Comparing the Two Populations at the Same Mechanism

When the same mechanism injures both a child and an elderly adult, expect different priorities. In blunt chest trauma, the child may show no rib fractures but have pulmonary contusion or cardiac contusion; the elder is likely to have multiple rib fractures with pain that limits breathing, increasing pneumonia risk. In falls, the child's compliant skeleton often protects internal structures while the head remains at risk; the elder faces fractures at multiple sites and occult intracranial bleeding if anticoagulated.

Safety Reminders

For both populations, err toward early transport decisions. Both groups decompensate faster than healthy adults. Document mechanism thoroughly—forces that seem minor may be devastating in these patients. Always reassess after every intervention and during transport.
