Study Notes
Patient Assessment Guidelines
- Rule #1: Assess every patient consistently by determining appearance: sick or not sick.
- For well-appearing patients, check five vital signs and note any abnormalities.
- Utilize a focused history and physical examination to guide assessment.
- Develop an assessment and differential diagnosis, followed by appropriate lab and imaging orders.
Pediatric Patient Interaction Techniques
- Employ observation strategies to gauge patient status.
- Consider examining the child while they sit in a parent's lap to reduce anxiety.
- Start with the least invasive parts of the exam; save painful or unsettling checks (e.g., ears and throat) for last.
- Use distraction techniques to ease the examination process.
- Familiarize children with medical tools by using relatable terms (e.g., an otoscope as a phone).
Emergency Response for Sick Patients
- Rule #2: In cases of illness, prioritize action over discussion.
- Immediate interventions include administering oxygen and assisting ventilation as needed.
- Essential monitoring: pulse oximetry and cardiorespiratory status.
- Establish IV access and consider chest X-ray (CXR) or EKG as necessary.
- Start treatment without definitive diagnosis when managing critically ill children; treatment should focus on life-threatening issues first.
Primary Survey Components
- A: Assess airway patency.
- B: Evaluate breathing and ventilation.
- C: Control circulation and address hemorrhage.
- D: Determine disability and neurological status.
- E: Ensure exposure and environmental control.
- Recognize that airway issues often lead to pediatric respiratory depression or arrest.
Airway Evaluation and Management
- Quickly determine if the airway is intact; if not, make airway management the primary focus.
- Observe for signs such as the ability to talk, appearance (pale, cyanotic), posturing, and sound (e.g., stridor).
- Identify risk factors such as angioedema, inhalation injury, trauma, and neck hematoma.
- Initiate oxygen therapy, monitor with pulse oximetry, and establish IV access promptly.
Pediatric Airway Characteristics
- Pediatric airways are smaller and more vulnerable to obstruction.
- The larynx is more anterior and superior, and the trachea is shorter, increasing the risk of right mainstem intubation.
- Funnel-shaped structure: narrowest at the subglottis in children under 8 years old.
- Other features include a large occiput and tongue, which predispose to soft tissue obstruction.
Airway Alignment and Adjuncts
- Use a shoulder roll for toddlers and a neck roll for older children to align the airway effectively.
- Combining jaw thrust with positional maneuvers improves pharyngeal and tracheal alignment.
- In young children, the tongue may obstruct the airway; consider using a nasopharyngeal airway if there's no facial trauma.
- An oropharyngeal airway can be employed in cases of decreased consciousness to maintain patent airway.
Bag Mask Ventilation
- Establish a proper seal between the mask and face using effective techniques.
- Perform a jaw thrust to maintain airway patency.
- Use a "C" grip technique, placing hands over the mask and onto the jaw for stability.
- Ensure there is adequate chest rise with each ventilation provided.
- If chest rise is inadequate, reposition the airway for better effectiveness.
- Ventilation rates: 25-30 breaths/min for infants, 15 breaths/min for older children.
- Avoid excessive ventilation to prevent risks of gastric air, regurgitation, aspiration, and barotrauma (such as pneumothorax).
- High intrathoracic pressure can impair venous return, reducing cardiac output, cerebral blood flow, and coronary perfusion.
Breathing Assessment
- Monitor breath sounds for clarity and equality of air entry.
- Evaluate work of breathing for signs of distress, such as retractions and nasal flaring.
- Grunting is a critical sign necessitating airway intervention.
Pediatric Arrest
- Pediatric arrests are seldom sudden and rarely stem from primary cardiac issues.
- Common underlying causes include respiratory failure and shock.
- Early recognition and rapid intervention are crucial for outcomes.
Respiratory Failure
- Characterized by inadequate oxygenation or ventilation.
- Causes include intrinsic lung diseases, airway obstructions, or inadequate respiratory effort.
- Distress usually precedes respiratory failure.
- Diagnosis is clinical and may not always rely on blood gas results.
Circulation
- Heart rate varies with age, making it a crucial factor in assessment.
- Blood pressure should be regularly monitored alongside central pulse evaluation (brachial in infants, femoral in older children).
- Additional assessment includes distal pulse and perfusion, noting mottled skin and delayed capillary refill.
Pediatric Blood Pressure
- Normal blood pressure maintenance persists until over 30% of the child’s blood volume is lost.
- Blood pressure alone is insufficient for assessing fluid resuscitation needs.
- Mean systolic blood pressure can be calculated using: 90 mmHg + (2 x age in years).
- Lower limit for normal blood pressure: 70 mmHg + (2 x age in years).
- Hypotension serves as a late indicator of shock in pediatric patients.
Shock
- Defined as inadequate delivery of oxygen or substrates to meet tissue demands.
- Signs of poor tissue perfusion include cool or mottled skin, tachycardia, and altered mental status (AMS).
- Shock can occur irrespective of blood pressure readings (normal, high, or low).
- Distinguish between compensated and uncompensated shock; hypotension represents a very late finding.
Fluid Resuscitation
- Initiate with isotonic fluids (normal saline or lactated Ringer's).
- Administer 20 ml/kg boluses until signs of improved perfusion and resolution of tachycardia are observed.
- For shock due to hemorrhage, administer PRBC (packed red blood cells) at 10 ml/kg after two fluid boluses.
Quick Neuro Exam
- Patient's mental status assessed using AVPU: Alert, Voice, Pain, Unresponsive.
- Evaluate pupils for size, reaction, and equality.
- Confirm movement of all four extremities.
- Check strength and sensation for symmetry.
Exposure
- Critical in trauma assessments.
- Ensure full body exposure, checking for injuries or abnormalities.
- Conduct examinations using light or finger in all orifices.
- Re-cover the patient promptly to prevent hypothermia.
AMPLE History
- A: List any Allergies.
- M: Record current Medications.
- P: Document Past medical history.
- L: Note the Last meal.
- E: Describe Events surrounding the visit.
Physical Exam: Secondary Survey
- Conduct head-to-toe examination after securing ABCs (Airway, Breathing, Circulation).
- Focus on identifying pertinent positives and negatives during evaluation.
Review
- Assess overall appearance of the patient; act accordingly if the patient appears sick.
- Initiate necessary procedures: oxygen therapy, pulse oximetry, monitoring, IV access, chest X-ray (CXR), and EKG as required.
- Ensure ABCDs are intact; address any issues in the prescribed order.
- Remember to check 5 vital signs and obtain AMPLE history.
- Complete the secondary survey to ensure comprehensive evaluation.
Primary Survey in Pediatric Trauma
- Follow the ABCDE approach: Airway, Breathing, Circulation, Disability, Exposure.
- Initial evaluations focus on immediate life threats, especially airway.
- Detailed history is unnecessary at the onset of treatment for critically injured children.
Injuries in Children
- Injury is the leading cause of death and disability among children.
- Injury-related mortality exceeds that of all other childhood illnesses combined.
- Motor vehicle collisions (MVCs) are the most frequent cause of death in this demographic.
- Children often present with multisystem injuries due to smaller body mass and anatomical considerations.
Head Injury
- Head injuries are the predominant cause of pediatric trauma fatalities.
- Unique anatomical features: proportionally larger head and softer cranium increase risk of injury without fractures.
- Types of head injuries include contusions, diffuse axonal injury, subdural hemorrhage, epidural hemorrhage, subarachnoid hemorrhage, and intraparenchymal hemorrhage.
- Management priorities: ensure oxygenation, maintain blood pressure, avoid hypoxia and hypotension for better outcomes.
- Signs of increased intracranial pressure (ICP) include unequal pupils and Cushing’s triad (high BP, irregular respirations, bradycardia).
- Recommended interventions: elevate head of bed to 30 degrees, use hypertonic saline (3%) at 5 ml/kg, and mannitol (0.5-1 mg/kg).
Chest Injuries
- Chest injuries often indicate additional trauma elsewhere in the body.
- Approximately two-thirds of children with chest damage will have other concurrent injuries.
- Significant thoracic trauma may occur without visible rib fractures due to the pliability of ribs in children.
- Pulmonary contusions are the most common blunt chest injury identified in this age group.
- The mediastinum's mobility increases the risk of pneumothorax.
Abdominal Trauma
- Most abdominal injuries result from blunt trauma like MVCs or falls.
- Children have a thinner muscular abdominal wall, making them more vulnerable to injuries of the liver and spleen.
- The presence of a seatbelt sign (linear bruising) significantly raises the likelihood of abdominal injury, necessitating a CT scan.
- The Focused Assessment with Sonography for Trauma (FAST) exam is not reliable for ruling out abdominal trauma in children.
- Solid organ injuries are the most prevalent and frequently managed non-operatively.
Pediatric Anatomic Considerations
- Pediatric skeleton is not fully calcified, making it more flexible and pliable.
- Infants have a soft cranium which allows for growth and protection of the brain.
- Fontanelles remain open until 12-18 months, providing flexibility during delivery and growth.
- Significant intracranial injuries may occur without accompanying skull fractures due to soft skull structure.
- Pulmonary contusions and thoracic injuries can occur even in the absence of rib fractures.
- Injuries at the growth plate can disrupt normal bone growth and development.
- Spine injuries are rare in children, despite other traumatic incidents.
- Anatomically, interspinous ligaments and joint capsules in children are more flexible than in adults, allowing for increased mobility.
- Facet joints in the pediatric spine are flat, contributing to the unique mechanics of spinal movement.
- Up to 40% of children may exhibit pseudosubluxation of C2 on C3, complicating diagnostic imaging.
- Radiographic evaluation of the spine can be challenging, necessitating a thorough neurological examination.
- The phenomenon of SCIWORA (spinal cord injury without radiographic abnormality) illustrates the need for caution in pediatric spinal assessments.
Physiologic Differences
- Normal vital signs exhibit greater variability in children compared to adults.
- Children possess a smaller circulating blood volume, estimated at 70-90 ml/kg.
- Pediatric patients can effectively compensate for significant blood loss through vasoconstriction before showing signs of hypotension.
- Hypotension in children is a late indicator of shock; early intervention is crucial to prevent rapid deterioration.
- Young patients are at increased risk for hypothermia due to less subcutaneous fat and connective tissue.
- Maintaining body temperature is critical, as hypothermia can exacerbate coagulopathy and acidosis in trauma situations.
Clinical Assessment and Management
- Initial assessment: Determine if the child is sick or not sick; abnormal vital signs warrant further investigation.
- If the child is unwell, focus on the "BIG FIVE" essential interventions:
- Ensure adequate oxygenation and provide ventilation support if necessary.
- Use pulse oximetry to monitor oxygen saturation.
- Implement continuous cardiorespiratory monitoring.
- Establish intravenous access for medication and fluid administration.
- Conduct a chest X-ray (CXR) and electrocardiogram (EKG) as part of the evaluation.
- Prioritize treatment for the greatest threats to life in the following order:
- Airway management
- Breathing support
- Circulatory stabilization
- Disability assessment
- Continuously reassess the patient after each intervention to evaluate the effectiveness of treatment measures.
