This document discusses resuscitation in children. It defines resuscitation and notes that the age of the victim guides treatment decisions. Discriminating based solely on age is inadequate, as there is no single parameter separating infants, children, and adults. Factors like size, illness, and rescuer strength should also be considered. The document then discusses various aspects of pediatric resuscitation, including airway management, breathing, chest compressions, defibrillation, and foreign body removal. It emphasizes the importance of ventilation for children and the need to tailor treatment based on the victim's age.

Resuscitation in children

2. Definition of resuscitation
 Is : an act or process of resuscitating someone or
something:
 A medical : the act or an instance of reviving
someone from apparent death or from
unconsciousness.
 is : the act or an instance of restoring someone or
something to an active or flourishing state

3. Age Definitions: What Defines an
Infant, Child, and Adult?
 The age of the victim is currently the primary
characteristic that guides decisions for application
of resuscitation sequences and techniques.
 Discrimination on the basis of age alone is
inadequate.
 Further, any single age delineation of the “child”
versus the “adult” is arbitrary because there is no
single parameter that separates the infant from
the child from the adult.
 The following factors should be considered.

4. cont
 There is consensus that the age cut-off for infants
should be at approximately 1 year. In general,
cardiac compression can be accomplished using
one hand for victims up to the age of
approximately 8 years.
 However, variability in the size of the victim or the
size and strength of the rescuer can require use
of the two-handed “adult” compression technique
for cardiac compression.

5. cont
 For instance, the chronically ill infant may be
sufficiently small to enable compression using
circular hand technique, and a 6- or 7-year-old
may be too large for the one-hand compression
technique.
 A small rescuer may need to use two hands to
effectively compress the chest of a child victim.

6. cont
 The resuscitation of children differs from that of
adults in a number of important ways. For
example, the most common cause of primary
cardiac arrest in adults is coronary artery disease,
whereas respiratory failure and shock are more
common causes among children and infants;
hypoxemia, hypercapnia, and acidosis
subsequently lead to bradycardia, hypotension,
and secondary cardiac arrest in children.

7. cont
 After resuscitation, survival to discharge may be
greater among children and adolescents than in
infants or adults.
 The survival rate without devastating neurologic
sequelae in children varies by age, ranging from
1% to 2% in infants and young children to 11% for
adolescents in whom a shockable rhythm is more
common; survival rates as high as 30% have
been seen after sudden out-of-hospital witnessed
ventricular fibrillation.

8. cont
 The best chance for a good outcome is to recognize
impending respiratory failure or shock and intervene
to prevent the development of cardiopulmonary
arrest.
 Age-related differences are important considerations
when treating children.
 An appropriate drug dose for a 6-month-old infant
may be excessive for a 1-month-old newborn but
inadequate for a 5-year-old child.
 Other aspects of resuscitation, such as endotracheal
tube size, tidal volumes, cardiac compression rates,
and respiratory rates, vary with a child's age.

9. cont
 Equipment selection and medication dosing are
based on age and body weight. Valuable time can
be lost in weight estimation, dosage calculations,
and equipment selection.
 Emergency personnel must be able to find the
proper equipment rapidly. Equipment can be
stored on shelves or in drawers labeled by age
and weight, or a system of color codes can be
used in which color-coded shelves, carts, or
equipment organizers correspond to specific
length categories as illustrated in

10. The Physiology of Cardiopulmonary
Resuscitation
 Outcomes after cardiac arrest remain poor more
than a half a century after closed chest
cardiopulmonary resuscitation (CPR) was first
described. This review article is focused on recent
insights into the physiology of blood flow to the
heart and brain during CPR.
 Over the past 20 years, a greater understanding
of heart–brain–lung interactions has resulted in
novel resuscitation methods and technologies
that significantly improve outcomes from cardiac
arrest.
 This article highlights the importance of attention
to CPR quality, recent approaches to regulate

11. cont
 intrathoracic pressure to improve cerebral and
systemic perfusion, and ongoing research related
to the ways to mitigate reperfusion injury during
CPR. Taken together, these new approaches in
adult and pediatric patients provide an innovative,
physiologically based road map to increase
survival and quality of life after cardiac arrest.

12. BASIC LIFE SUPPORT
 The American Heart Association Guidelines use
the following age group delineations: newborn, 1
month or less in age; infant, 1 month to 1 year of
age; and child, 1 year of age to the onset of
puberty.
 As in adults, the priorities of resuscitation are
airway, oxygenation, ventilation, and shock
management.

13. Cont
 An important change in the 2010 American Heart
Association Guidelines is the order of basic life
support assessment.
 Instead of using ABC (airway, breathing,
circulation) as a mnemonic, the American Heart
Association recommends CAB, emphasizing the
importance of chest compressions beginning as
rapidly as possible

14. cont
 Reasons for this change in approach include the
following: starting with chest compressions
reduces the delay to the start of the first
compression; all rescuers can start chest
compressions immediately, because airway
management requires manipulation and
positioning of the patient; and simplifying the
basic life support resuscitation approach is
consistent for ...

15. cont
 Ideally the sequence of resuscitation should be
determined by the most likely cause of the arrest.
 In the newly born infant this will be most likely
related to respiratory failure.
 In the older infant and child it may be related to
progression of respiratory failure, shock, or
neurological dysfunction.

16. cont
 In general, pediatric pre hospital arrest has been
characterized as hypoxic, hypercarbic arrest with
respiratory arrest preceding asystolic cardiac
arrest.
 Therefore, a focus on early ventilation and early
CPR (rather than early emergency medical
services [EMS] activation and/or defibrillation)
appears to be warranted.

17. cont
 Early effective oxygenation and ventilation must
be established as quickly as possible.
 Primary dysrhythmic cardiac arrest may occur
and should particularly be considered in patients
with underlying cardiac disease or history
consistent with myocarditis.

18. Resuscitation Sequence/EMS
Activation
 Local response intervals, dispatcher training, and
EMS protocols may dictate the sequence of early
life support interventions.
 In addition, the sequence of resuscitation actions
must consider the most likely causes of arrest in
the victim.

19. cont
 Respiratory failure and/or trauma may be the
primary etiologies of cardiopulmonary arrest in
victims aged 40 years or younger,68 with a
relatively low incidence of primary ventricular
fibrillation (VF).
 One critical issue in determining the sequence of
interventions is whether the primary cause of
arrest is due to a cardiac or respiratory etiology.
 The probability of successful resuscitation based
on that etiology is another important unresolved
resuscitation question

21. Determination of
Responsiveness
 Unresponsiveness mandates assessment and
support of airway and breathing. Infants and
patients with suspected cervical spinal injury
should not be shaken to assess responsiveness.

22. Airway
 Consensus continues to support use of the head
tilt–chin lift or the jaw thrust (the jaw thrust
especially when cervical spine instability or neck
trauma is suspected) to open the airway.
 Other maneuvers, such as the tongue–jaw lift,
may be considered if initial ventilation is
unsuccessful despite repositioning of the head.
The most common cause of airway obstruction in
the unconscious pediatric victim is the tongue.

23. cont
 Although the use of a tongue–jaw lift and visual
mouth inspection prior to ventilation of any
unconscious infant may be considered if foreign
body airway obstruction is strongly suspected,
there are no data to support the delay of
attempted ventilation in all victims.

24. cont
 Although the use of a tongue–jaw lift and visual
mouth inspection prior to ventilation of any
unconscious infant may be considered if foreign
body airway obstruction is strongly suspected,
there are no data to support the delay of
attempted ventilation in all victims. CPR.

25. Breathing
 There is general consensus regarding the
technique for rescue breathing for infants and
children.
 The current recommendations for initial number
of attempted breaths, however, vary from 2 to 5.
 There are no data to support any specific number
of initial breaths.
 There was agreement that a minimum of 2
breaths be attempted.
 The rationale for attempting to deliver more than
2 initial ventilations includes the need to provide
effective ventilation for pediatric victims based
upon the likely hypoxic ,

26. cont
 hypercarbic etiology of arrest, suspected inability
of the lay rescuer to establish effective ventilation
with only 2 attempts, and clinical impressions that
more than 2 breaths may be required to improve
oxygenation and restore effective heart rate in the
apneic, bradycardic infant.

27. cont
 Initial breaths should be delivered slowly, over 1.0
to 1.5 seconds, with a force sufficient to make the
chest clearly rise.
 Care and attention to abdominal distention
caused by insufflation of gas into the stomach
should be recognized and avoided.

28. cont
 Consideration of the optimal method for delivering
breaths to infants supports the current
recommendation of mouth to mouth-and-nose
ventilation for infants up to 1 year old.
 However, mouth-to-nose ventilation may be
adequate in this population.

29. cont
 Consensus continues to support the emphasis on
the provision of more ventilation (breaths per
minute) for infants and children and more
compressions per minute for adult victims.
 Current recommended ventilation rates are
based on normal ventilatory rates for age, the
need for coordination with chest compression,
and the perceived practical ability of the rescuer
to provide them .
 Ideal ventilation frequency during CPR is
unknown.

30. Circulation
 There is a lack of specific pediatric data on the
accuracy and time course for determining
pulselessness of victims who are apneic and
unresponsive.
 Several reports have documented the inability of
lay rescuers and healthcare providers to reliably
locate or count the pulse of the victim.
 The utility of the pulse check during pediatric
CPR has been questioned.

31. cont
 Furthermore, the pulse check is difficult to teach
to laypersons.
 It seems reasonable for healthcare providers to
search for a pulse because it may be palpated by
trained personnel, does not require sophisticated
equipment, and there is no better alternative.
 However, resuscitative interventions should not
be delayed beyond 10 seconds if a pulse is not
confidently detected.

34. Chest Compression
 When to Start
 There is consensus that all pulseless patients and
patients with heart rates too low to adequately
perfuse vital organs warrant chest compressions.
 Because cardiac output in infancy and childhood
is largely heart-rate dependent, profound
bradycardia is usually considered an indication
for cardiac compressions.

35. cont
 Location of Compression
 There is consensus for compression over the lower
half of the sternum, taking care to avoid compression
of the xiphoid.
 Depth
 Consensus supports recommendation of relative
rather than absolute depth of compression (eg,
compress approximately one third of the depth of the
chest rather than compress 4 to 5 cm).
 Effectiveness of compression should be assessed by
the healthcare provider.

36. cont
 Methods of assessment include palpation of
pulses, evaluation of end-tidal carbon dioxide,
and analysis of arterial pressure waveform (if
intra-arterial monitoring is in place).
 Although it is recognized that pulses palpated
during chest compression may reflect venous
rather than arterial blood flow during CPR,36
pulse detection during CPR for healthcare
providers remains the most universally practical
“quick assessment” of chest compression
efficacy.

37. cont
 Rate
 Consensus supports a rate of approximately 100
compressions per minute. With interposed
ventilations, this will result in the actual delivery of
<100 compressions to the patient in a 1-minute
period.

38. Compression-to-Ventilation Ratio
 Ideal compression-ventilation ratios for infants
and children are unknown. A single, universal
compression-ventilation ratio for all ages and both
BLS ( basics life support) and ALS interventions
would be desirable from an educational
standpoint.
 There currently is consensus among resuscitation
councils for a compression-ventilation ratio of 3:1
for newborns and 5:1 for infants and children.
 The justification for this difference from adult
guidelines includes the fact that respiratory
problems are the most common etiology of
pediatric arrest and therefore ventilation should
be

39. cont
 emphasized, and physiological respiratory rates
of infants and children are faster than those of
adults.
 Although the actual number of delivered
interventions is dependent on the amount of time
the rescuer spends opening the airway and the
effect of frequent airway repositioning on rescuer
fatigue, there is insufficient evidence to justify
changing the current recommendations for
educational convenience at this time.

40. cont
 External chest compression must always be
accompanied by rescue breathing in children.
 At the end of every compression cycle a rescue
breath should be given.
 Interposition of compressions and ventilations is
recommended to avoid simultaneous
compression/ventilation.

41. Activation of the EMS System
 Ideally the sequence of resuscitation is
determined by the etiology of the arrest.
 In pediatric arrest, dysrhythmias requiring
defibrillation are relatively uncommon, and some
data suggest that early bystander CPR is
associated with improved survival.

42. cont
 However, it is impractical to teach the lay public
different resuscitation sequences based on arrest
etiology.
 The consensus recommendation is “phone fast”
rather than “phone first” for young victims of
cardiac arrest, but the appropriate age cut-off for
this recommendation remains to be determined.
 Local EMS response intervals and the availability
of dispatcher-guided CPR may override these
considerations.

43. Recovery Position
 There is consensus that an ideal recovery
position considers the following: etiology of the
arrest and stability of the C-spine, risk for
aspiration, attention to pressure points, ability to
monitor adequacy of ventilation and perfusion,
maintenance of a patent airway, and access to
the patient for interventions.

44. Relief of Foreign-Body Airway
Obstruction
 There are three suggested maneuvers to remove
impacted foreign bodies: 1 back blows, chest
thrusts, and abdominal thrusts.
 The sequences differ slightly among
resuscitation councils, but published data do not
convincingly support one technique sequence
over another.

45. cont
 There is consensus that the lack of protection of
the upper abdominal organs by the rib cage
renders infants and newborns at risk for
iatrogenic trauma from abdominal thrusts;
therefore, abdominal thrusts are not
recommended in infants and newborns.
 An additional practical consideration is that back
blows should be delivered with the victim
positioned head down, which may be physically
difficult in older children.
 Suctioning is recommended for newborns rather
than back blows or abdominal thrusts, which are
potentially harmful to this age group.

49. cont
 IMMEDIATE MANAGEMENT – BASIC LIFE
SUPPORT – CARDIOPULMONARY
RESUSCITATION (CPR)
 Airway
 Clear the airway using the most appropriate
measures:
 • Suction, in the case of vomitus, secretions or
blood.
 • Manual clearance. Under direct vision insert
your fingers into the pharynx and remove food,
dentures or foreign bodies. Avoid “blind” finger
sweeps.

52. breathing
 Breathing
 Mouth-to-mouth respiration. Do this if there is no
apparatus available to ventilate the patient, e.g. if the
cardiac arrest occurs outside the hospital.
 Clear the airway as explained above. Extend the head
and lift the jaw up. Kneel beside the patient's head.
Take a deep breath. Pinch the patient's nose with
your free hand. Apply your lips to the patient's mouth
to provide a seal. Blow into the patient's chest. Note
the rise and fall of the chest. Do this 12-15 times per
minute. Allow approximately 1-2 seconds for
inspiration and 3 seconds for expiration. In infants,
mouth to nose breathing works well. Give only gentle
puffs to avoid lung rupture.

54. disadv
 Disadvantages:
 It is not a very pleasant procedure to carry
out.
 The patient is ventilated with expired gases
which contain only 16% oxygen.
 The rescuer tends to get "dizzy" after a few
minutes because of low carbon dioxide. Mouth-
to-mouth resuscitation cannot be carried out for
long.

56. ventillation
 Ventilation using a bag, valve and mask. A non-
rebreathing valve, self– inflating bag and mask may
be used. This enables the patient to be ventilated
more effectively.
 • Clear the airway completely, as described
previously.
 • Make sure the chest moves every time the bag is
squeezed.
 • An air-tight seal between the face and the mask
is necessary to inflate the lungs. A self- inflating bag
fills during expiration regardless of the seal and a
one-way valve allows ventilation of the patient with
100% oxygen. A flow rate of 10L/min is necessary to
remove carbon dioxide.
 (Endotracheal intubation is not an emergency
measure. Ventilation can be quite effective using a
mask and bag provided the rules are followed.

59. Vascular Access
 Vascular access for the arrested victim is needed for
the delivery of resuscitative fluids and medications.
 However, establishment of adequate ventilation with
BLS support of circulation is the first priority.
 The intravenous or intra osseous route for the delivery
of medications is the preferred route, but the
endotracheal route can be used in circumstances
when vascular access is delayed.
 It is likely that drug delivery following endotracheal
epinephrine administration may be lower than that
delivered by the intravascular approach.
 Drug doses may need to be

60. cont
 increased accordingly, with attention to drug
concentration, volume of vehicle, and delivery
technique.
 There is consensus that the tibial intra osseous
route is useful for vascular access, particularly for
victims up to the age of 6 years.
 In the newly born, the umbilical vein is easy to
find and frequently used for urgent vascular
access.

61. Complications From CPR
 Reported complications from appropriately applied
resuscitative techniques are rare in infants and
children. The prevalence of significant adverse effects
(rib fractures, pneumothorax, pneumoperitoneum,
hemorrhage, retinal hemorrhages, from properly
performed CPR appears to be much lower in children
than in adults.
 In the most recent study,59 despite prolonged CPR by
rescuers with variable resuscitation training skill
levels, medically significant complications were
documented in only 3% of patients.
 Therefore, there is consensus that chest
compressions should be provided for children if the
pulse is absent or critically slow or if the rescuer is
uncertain if a pulse is present.

 • ECM can be performed by anyone
 • No equipment is required
 • No risk of infection
 • Ventilation is not interfered with.
 Dangers
 • Fractured ribs
 • Pneumothorax
 • Injury to liver
 Internal Cardiac Massage (ICM)
 This approach is rarely necessary but may be indicated:
 • When cardiac arrest occurs intra operatively, the chest or abdomen is
already opened and the surgeon is present.
 • In trauma arrests, e.g. penetrating chest wounds, severe chest crush
injuries, haemothorax.
 • If ECM is ineffective because of underlying pathology, e.g. pericardial
tamponade, severe scoliosis
