Cardiopulmonary Resuscitation Shamiel Salie Paediatric Intensive Care Unit Red Cross Children’s Hospital, University of Cape Town
Age Definitions: • Newborn • Infant - under 1 year • Child - from 1 year to puberty
2005 BLS Changes: • Lay rescuers should start compressions for an unresponsive child who is not breathing/moving • Universal compression-ventilation ratio of 30:2 for the lone rescuer of infants, children and adults • Increased evidence on the importance of uninterrupted chest compressions
Compression Techniques Position: for all ages: compress the lower third of the sternum number of hands: • In infants: two thumbs or two fingers • in children: use one or two hands: depressing the sternum by approximately one third of the depth of the chest
Chest Compressions • Push hard • Push Fast • Complete chest recoil • Minimize interruptions
Calling for help!! • Perform 5 cycles or about 2 minutes of CPR before calling for help • Indications for activating EMS before BLS by a lone rescuer are: • witnessed sudden collapse with no apparent preceding morbidity • witnessed sudden collapse in a child with a known cardiac abnormality
Universal Algorithm
Drugs in Cardiac Arrest • 10mcg/kg of adrenalin as the first and subsequent iv doses. • high dose iv adrenalin is not recommended and may be harmful • Insufficient evidence to recommend for or against the routine use of vasopressin in children
Route of drug delivery in ALS • where possible give drugs intra-vascularly rather than via the tracheal route • lower adrenaline concentrations may produce transient beta adrenergic effects resulting in hypotension. • Intra-osseous access is safe for fluid resuscitation and drug delivery.
Airway Management • guedel airways • laryngeal airways • Cuffed or uncuffed endotracheal tubes
Number of Defibrillating Shocks • one shock rather than three “stacked” shocks • Modern biphasic defibrillators have a high first shock efficacy • Most patients have a non perfusing rhythm after successful defibrillation
AED IN CHILDREN • Age > 8 years • use adult AED • Age 1-8 years • use paediatric pads / settings if available (otherwise use adult mode) • Age < 1 year • use only if manufacturer instructions indicate it is safe
Fluid Resuscitation • Boluses of fluid may be required to maintain systemic perfusion • Crystalloids - ringers or normal saline • Septic children may require in excess of 100ml/kg fluid resuscitation
Family Presence during Resuscitation • Evidence suggests that the majority of parents would like to be present during resuscitation, that they gain a realistic understanding of the efforts made to save the child, and they subsequently show less anxiety and depression.
When do you stop? • In the absence of reversible causes eg drowning with severe hypothermia, poisoning, prolonged CPR in children is unlikely to result in intact neurological survival. • One should consider stopping resuscitation after 20 minutes.
Post Resuscitation Care • Ventilate to normo-capnoea • Hypothermia for 12-24 hours post arrest may be helpful, whilst hyperthermia should be treated aggressively • Vaso-active drugs should be considered to improve haemodynamic status. • Maintain normoglycaemia
Conclusions: • The 2005 guidelines minimizes the differences in the steps and techniques of CPR used for infants, children and adults. • Push hard, push fast, minimizing interruptions • Respiratory failure and hypoxia is the commonest reason for paediatric arrests. • There are usually warning signs of impending doom, and early and effective therapy will prevent cardiac arrest
