EMT: Pediatric Trauma Considerations
This lesson focuses on essential considerations for EMTs when managing pediatric trauma patients. Children's unique anatomical and physiological differences significantly impact injury patterns and responses, necessitating a specialized approach to assessment and care.
Anatomical and Physiological Differences in Pediatric Trauma
Understanding these differences is crucial for predicting injury patterns and managing pediatric trauma effectively.
Larger Head Relative to Body: Infants and young children have proportionally larger and heavier heads, increasing the risk of head and cervical spine injuries in falls and collisions.
Thinner Skull and Less Developed Cranial Bones: Offer less protection to the brain.
Softer, More Pliable Skeleton: Bones are more flexible and have open growth plates, leading to different fracture types (e.g., greenstick, buckle fractures) and increasing the risk of internal injury without obvious external signs.
Less Muscle Mass and Subcutaneous Fat: Provides less protection for internal organs, making them more vulnerable to blunt force trauma.
More Elastic Chest Wall: Can absorb significant force without rib fractures, leading to occult internal organ damage (e.g., pulmonary contusion, myocardial contusion) without external bruising.
Higher Metabolic Rate and Limited Glycogen Stores: Children are more susceptible to hypothermia and hypoglycemia following trauma.
Increased Surface Area to Volume Ratio: Greater heat loss, leading to rapid development of hypothermia.
Psychological and Emotional Responses: Fear, pain, and anxiety can complicate assessment and cooperation.
Common Mechanisms of Injury and Associated Patterns
The mechanism of injury (MOI) provides vital clues about potential injuries.
Blunt Trauma: Most common mechanism in pediatric trauma.
Falls: Common in all age groups. Injury patterns depend on the height of the fall and the child's developmental stage. Low-height falls often result in isolated long bone fractures; high-energy falls can cause multi-system trauma.
Motor Vehicle Crashes (MVCs): Injury patterns depend on restraint use (or lack thereof), seating position, and type of collision. Special attention to car seat proper installation and usage is critical.
Bicycle Handlebar Injuries: Often result in intra-abdominal compression injuries (e.g., liver or spleen lacerations).
Pedestrian vs. Vehicle: Common in school-aged children. Injuries can be severe and multi-system.
Penetrating Trauma: Less common but highly lethal.
Requires rapid assessment and transport.
Prehospital Assessment and Management Principles
Scene Safety: Always prioritize.
Primary Assessment (ABCs): Ensure airway patency, adequate breathing, and circulation. Children can decompensate rapidly.
C-spine Immobilization: Assume spinal injury in significant trauma until ruled out.
Oxygen Administration: High-flow oxygen for all significant trauma patients.
Hemorrhage Control: Apply direct pressure to external bleeding.
Fluid Resuscitation: Administer fluid boluses (20 mL/kg isotonic crystalloids) for signs of shock, but avoid over-resuscitation in head trauma.
Temperature Management: Prevent hypothermia (remove wet clothing, blanket, warm environment).
Pain Management: Provide comfort measures and consider appropriate analgesia (per protocol).
Rapid Transport: To the nearest appropriate trauma center.
Child Abuse/Neglect: Maintain a high index of suspicion for non-accidental trauma, especially when MOI is inconsistent with injuries or parental history changes.
Critical Thinking Questions
You respond to an MVC involving a 4-year-old child who was unrestrained. What specific injury patterns would you anticipate, and how would your assessment be tailored for this patient?
A child presents with significant blunt abdominal trauma but no obvious external signs of injury. Explain why internal organ damage is a high suspicion in pediatric patients even without external marks.
You are assessing a school-aged child who fell from a significant height. Besides obvious fractures, what other critical injuries should you be looking for, and why are these more prevalent in children?
Discuss the importance of strict temperature management in a pediatric trauma patient and the physiological reasons behind this.
What red flags in a pediatric trauma case would raise your suspicion for child abuse or neglect, and what actions should an EMT take if abuse is suspected?
