  • CP arrest in infants and children is rarely a sudden event. Instead, it is often the end result of progressive deterioration in respiratory and circulatory function. No matter what the cause is, the end result in this deterioration is the development of cardiopulmonary failure and possible arrest. If pulseless cardiac arrest develops, there is very poor prognosis. If the clinician recognizes early the manifestations of respiratory failure or shock and quickly starts therapy then cardiopulmonary arrest can often be prevented.
  • Skilled physical examination is needed to recognize cardiopulmonary deterioration in the infant or child. Laboratory tests are useful adjuncts in determining the severity of physiologic derangements but they are not crucial to the initial evaluation. Every clinician who works with children should be able to recognize potential pulmonary and circulatory failure and impending cardiopulmonary arrest based on a rapid CP assessment. The rapid CP assessment is designed to evaluate pulmonary and cardiovascular functions and their effects on end-organ perfusion and function.
  • Since the conditions of these patients are often dynamic, repeated assessments are necessary to evaluate trends in their conditions or the responses to therapy.
  • Hypovolemic shock is the leading form of shock in children worldwide.
  • Since cardiac and cardiopulmonary arrest in children is most commonly associated with the development of hypoxemia rather than with ventricular arrhythmias, about 1 min of rescue support may restore oxygenation and effective ventilation or may prevent the child with respiratory arrest from developing cardiac arrest.
  • If the infant or child is unresponsive, has no evidence of trauma and obviously breathing effectively, the rescuer should place the victim in the recovery position and activate EMS.
  • Cardiac output = volume of blood ejected by the heart each minute. Stroke volume = volume of blood ejected by the ventricles with each contraction. Of the variables affecting and affected by cardiac output, only the heart rate and blood pressure can be easily measured. Stroke volume and systemic vascular resistance must be indirectly assessed by examining the quality of pulses and evaluating tissue perfusion.
    Blood pressure is the product of cardiac output (flow) and systemic vascular resistance. Normal BP can be maintained despite a fall in cardiac output only if compensatory vasoconstriction occurs. Hypotension is a late and often sudden sign of cardiovascular decompensation. Therefore, even mild hypotension must be treated quickly and vigorously because it signals decompensation and CP arrest may be imminent. An observed fall of 10 mm Hg in systolic BP should prompt careful serial evaluations for additional signs of shock.
  • Epinephrine: for cardiac arrest, symptomatic bradycardia unresponsive to ventilation and oxygenation and hypotension not related to volume depletion; severe acidosis may depress its action, thus, should be corrected first with oxygenation, hyperventilation and restoration of systemic perfusion.
    Atropine: symptomatic bradycardia associated with poor perfusion, intubation and AV block; not indicated for asystole or cardiac arrest.
    Isoproterenol: for heart block unresponsive to atropine, for bradycardia with poor perfusion.
    Dopamine: for hypotension or poor peripheral perfusion with adequate intravascular volume and stable rhythm; for cardiogenic, distributive (DSS) and hypovolemic shock conditions.
    Dobutamine: for hypoperfusion with high systemic vascular resistance; most effective in severe congestive failure or cardiogenic shock.
  • This is due to larger head of a child than adult, more likely to “lead” in the fall.
    Cervical spine injury may be anatomic or functional.
    SCIWORA cannot be ruled out by radiographic examination and must be assumed to be present in all children with multiple injuries especially those apneic; accounts for large number of prehospital deaths previously thought to be due to head trauma.
  • In hemorrhagic shock: 3 for 1 rule, 3ml blood loss to 1 ml fluid.

    5. 5. Child Development and Injuries Temperament: a child’s behavioral style 1. Difficult child: irregular rhythm, high energy, negative mood, low adaptability 2. Easy child: opposite 3. Slow to warm up child: low activity, positive approach, highly adaptable, mild energy Motivation: interest in accomplishing a task 1. Normal drive for autonomy 2. Interest in imitating behavior 3. Risk-taking or self-destructive behaviors
    6. 6. Child Development and Injuries Competencies: level of functioning 1. Infants’ drive to explore and become autonomous but still underdeveloped 2. Preschool children have cognitive and motor limitations 3. School children tend to be daring, impulsive and adventurous; inclined to disregard rules; still unable to appreciate speed and danger; have reduced ability to localize sounds and impaired perception of movement 4. Adolescents become overly involved in abstract matters and sometimes lose touch with reality combined with innate need for experimentation and the tendency to imitate older adolescents and adults

Injury Morbidity Twenty to 25% of children receive medical care for injury every year in hospital ERs and at least an equal number in physician offices Falls leading cause of both ER visits and hospitalizations Bicycle-related trauma most common type of sports and recreational injury
    15. 15. DOH 2003 Study By the Department of Health: 1 out of every 5 Filipino children die from injuries 2003 DOH study done with help from the United Nations Children’s Fund and the Alliance for Safe Children revealed that the top causes of death among children ages 1-17 years are: 1. Drowning (8:100,000) 2. Road accidents (5.85:100,000) 3. Violence (2.52:100,000) 4. Falls (2.11:100,000) 5. Suicide (1.93:100,000) The study was made on 99,446 households or 418,552 people
    16. 16. Safe Kids Philippines Study The study was conducted in the ERs of 3 hospitals in Parañaque, Pasay, and Olongapo At least 20 million Filipino children are at risk of dying or being injured in road accidents every yr At least one in four children brought to hospital for treatment were between 12-14 years Most of the injuries happen after 1 p.m. and their peak incidence between 9 p.m. and 12 a.m. Accidental injuries are the third leading cause of death for children 1-14 years in the Philippines

Pediatric Trauma Resuscitation Trauma is the leading cause of death and disability in the pediatric age group In the average multiple trauma victim: head injuries 59% while extremities 26% Two major causes of death: 1) Airway compromise 2) Unrecognized hemorrhage Traumatic injuries that may affect successful resuscitation: 1) Cervical spine injury 2) Hemorrhage 3) Chest trauma Priority is to assess and stabilize first before surgery
    41. 41. Pediatric Trauma Score of > 8 indicates multisystem trauma or significant mortality risk
    42. 42. Cervical Spine Injury Cervical spine injury less common in pediatric than in adult trauma because  Child’s spine more elastic and mobile  Pediatric vertebrae softer, less likely to fracture But risk of cervical spine injury increased whenever child is subjected to inertial forces applied to neck during acceleration-deceleration e.g., motor vehicle injuries or falls from a height Spinal cord injury without radiographic abnormality (SCIWORA) is now recognized as important cause of pediatric spinal cord injury because of  Relative laxity of cervical spine ligaments  Incomplete development of cervical musculature  Shallow orientation of facet joints
    43. 43. Cervical Spine Immobilization
    44. 44. Hemorrhage in Pediatric Trauma Control external hemorrhage immediately by direct pressure over the wound Hypotension will not be present until 25-30% or more of the child’s blood volume is lost acutely Reliable vascular access must be obtained quickly If shock persists despite control of external hemorrhage and volume resuscitation, internal bleeding is likely Isolated head injury rarely causes sufficient blood loss to cause shock but scalp lacerations may produce significant blood loss Intra-abdominal bleeding signs due to organ rupture: abdominal tenderness, distention that does not improve with NGT decompression and shock – a life-threatening surgical emergency

    46. 46. Life-Threatening Chest Injuries Chest injuries uncommon in pediatric trauma because chest wall extremely compliant When there is history of blunt trauma, intrathoracic injuries must be ruled out Tension pneumothorax: ABCs, needle decompression followed by chest tube Open pneumothorax (sucking chest wound) – rare but lethal: ABCs, occlusive dressing followed by chest tube, positive-pressure ventilation Flail chest: ABCs, prolonged positive-pressure ventilation Massive hemothorax: ABCs, urgent placement of a chest tube

    49. 49. Haddon’s 10 Strategies 1. Prevent the creation of hazard 2. Reduce amount of hazard brought into being (decrease number of cars manufactured; use fuel that permits only low speed) 3. Prevent the release of hazard (drive only in daylight) 4. Modify the rate of release of the hazard from its source (use seat belts, child safety seat) 5. Separate the hazard by time and space (separate bicyclists from cars; use pedestrian lanes)
    50. 50. Haddon’s 10 Strategies 6. Separate the hazard by a physical barrier (install air bags) 7. Modify relevant basic qualities of the hazard (eliminate hard surfaces in cars; use energy absorbing materials to increase space within) 8. Make what is to be protected resistant (wear helmets) 9. Begin to counter the damage done by the hazard (maintain airway, stop hemorrhage, immobilize neck) 10. Stabilize, repair, rehabilitate the object of the damage (develop a regional trauma system, trauma and rehabilitation center)
