Paediatric Emergencies in the Recovery Room Michelle McNamara Proposed Learning Paediatric Emergencies A.B.C.D.E Airway Breathing Circulation Disability (depressed consciousness, unresponsiveness). Exposure ( significant hypothermia, bleeding, shock). Paediatric Challenges Not ‘Small’ Adults Are Someone's Child Age groups – size, development Opiate use intra-op/Post-op Emergence delirium Families Fear of mistakes Paediatric Considerations Higher Anaesthetic Morbidity & Mortality Higher Intra-operative Bradycardia (Infants) Higher Respiratory Complications (Recovery) Associated outcomes worse Complications occur in healthy children of normal weight Paediatric Anaesthesia Report Patient specific additions Defer verbal report if condition is unstable or emergency intervention is warranted. Birth history (premature birth, or congenital conditions). Developmental considerations (ensure personal comfort items are present, toy, blanket, religious items). Special needs (e.g. glasses, hearing implants) Pre-operative behaviour, (calm or anxious). Loose teeth (returned for tooth fairy). Approach to Paediatric Assessment ASSESS (General, Primary, Secondary, Tertiary) CATEGORIZE (Respiratory, Circulatory) DECIDE (Course of Action) ACT (Initiate Appropriate Treatment for Clinical Condition & Severity REASSESS The Above Process Is Ongoing e.g. reassess after any intervention to ensure effectiveness Assessment General Primary Secondary Tertiary SAMPLE Signs & Symptoms Allergies Medication Past Medical History Last Meal Events Paediatric Definitions Premature Newborn – Birth before 37/40 Newborn – Birth to 72 hours Neonate - Infant during first 28 days of life Infant - 1st year of life (including neonate) Toddler 1-3yrs Preschooler 4-5yrs School Age 6 – 12yrs Adolescent > 13yrs Airway Approach to Paediatric Assessment ASSESS (General, Primary, Secondary, Tertiary) CATEGORIZE (Respiratory, Circulatory) DECIDE (Course of Action) ACT (Initiate Appropriate Treatment for Clinical Condition & Severity REASSESS The Above Process Is Ongoing e.g. reassess after any intervention to ensure effectiveness Anatomy and Physiology Airway Large Tongue Narrow Nostrils Smaller Airway Opening Short Neck Neonates are obligatory nose breathers More Susceptible to Laryngeal / Bronchospasm Easily Obstructed Airway Post Intubation Oedema Airway problems Tracheal intubation (under 5 years) History of pre-term birth Reactive airway disease Airway surgery Excessive Secretions/Nasal Congestion Parents who smoke. Breathing Approach to Paediatric Assessment ASSESS (General, Primary, Secondary, Tertiary) CATEGORIZE (Respiratory, Circulatory) DECIDE (Course of Action) ACT (Initiate Appropriate Treatment for Clinical Condition & Severity REASSESS The Above Process Is Ongoing e.g. reassess after any intervention to ensure effectiveness Normal Respiratory Rate by Age Age Breaths Per Minute Infant (< 1yr) Toddler (1 – 3yrs) Preschooler (4 – 5yrs) School Age (6 – 12yrs) Adolesent (13 – 18 years) 30 – 60 24 - 40 22 – 34 18 – 30 12 - 16 A respiratory Rate consistently > than 60 bpm in a child of any age is abnormal Normal Spontaneous Ventilation Minimal work Quiet breathing Easy inspiration Passive expiration Rapid in the neonate Decreases in older infants & children Paediatric Considerations (Respiratory) High metabolic rate Oxygen demand is higher Infant Oxygen Consumption is 6-8mls/kg per minute (compared to 4mls/kg for adults) Hypoxaemia more rapid in infants & children A room air Sao2 < 94% in a normal child indicates hypoxaemia. Causes of Respiratory Dysfunction Post Op Residual effects of anesthetic agents Opiate Agents Sedative agents Excessive fluid volume Pain/ Anxiety Hypothermia/Hyperthermia Pre-existing Pulmonary Disease. Early Respiratory Distress Increased Respiratory & Heart Rate; Decreased Oxygen Saturation, Nasal Flaring (Infants); Chest Retractions, use of Accessory Muscles; Poor chest rise Poor air entry Grunting Croup Stridor Wheezing Mottled Colour LATE Respiratory Distress Bradypnoea No respiratory effort Apnoea Cyanosis Poor or absent distal air movement Coma Types of Respiratory Distress Upper airway obstruction Lower airway obstruction Lung Tissue Disease Disordered control of breathing Croup Inflammation of the upper airway Post-intubation croup Presentation -'bark-like' cough Mild, Moderate, or Severe Causes of Croup Intubation (Traumatic Prolonged or Repeated) Tight fitting E.T.T. Subglottic Injury Coughing (with E.T.T in place) Change of position (whilst Intubated) Surgery >1 hour Surgical trauma May be accompanied by Stridor Respiratory Distress Stridor Shrill Harsh loud Crowing sounds Heard during inspiration, expiration or both. Management of Croup / Stridor Notify Anaesthetist Nebulised cool mist Steroid IV Humidified oxygen Keep N.P.O. Nebulised Epinepherine Keep Pt > 2hrs Re-intubate (size smaller ETT than calculated for the age of the child) Laryngospasm Involuntary muscle contraction of the laryngeal muscles causing the vocal cords to close. Dyspnoea Crowing sound on Inspiration Aphonia (no sound) Rocking Motion of Chest Use of Accessory Muscles. Laryngospasm Nursing Interventions Notify Anaesthetist Administer 100% Humidified Oxygen Positive Pressure Ventilation by BVM Maintaining PEEP to Open Vocal Chords. Prepare for Intubation Oropharyngral Suction as required Bag Mask ventilation Signs & Symptoms Lower airway obstruction Tachypnoea Wheezing, (expiratory most common) Increased respiratory effort Retractions Nasal flaring Prolonged expiration (with expiration being an active rather than a passive process). Bronchospasm Causes Preexisting Airway Disease Asthma, Bronchiolitis Allergy/Anaphalaxis Aspiration Mucous plug Foreign Body Pulmonary Edema. Bronchospasm / Asthma Treatment Notify Anaesthetist Humidified Oxygen 100% Suction Bronchodilators / Ventolin Support ventilation Intubate if necessary Admission overnight Aspiration Causes Residual gastric volume (intra-op) Post op Nausea & Vomiting Inhalation of foreign body e.g. tooth Inability to protect airway Aspiration Nursing Interventions Position head down & turned to the side to promote drainage Humidified Oxygen/Suction Anti-emetic prophylaxis / rescue Notify anaesthetist Chest x-ray I.V. Antibiotic Prepare to re-intubate if necessary Respiratory Management Distress/Failure/Obstruction Notify Anesthetist Reposition/Support the airway Open airway Clear the airway Insert an O.P.A. Or N.P.A.
