  1. 1. May 2020
  2. 2. Preterm 27% Sepsis & pneumonia 26% Asphyxia 23% Congenital 7% Tetanus 7% Diarrhoea 3% Others 7% 4 million neonatal deaths: When? Where? Why? Lancet 2005; 365: 891– 900
  3. 3. WHY TO LEARN NEWBORN RESUSCITATION ?  Birth asphyxia ~25% neonatal mortality  ~90% requiring little or no assistance  10% of newborns need some assistance  Only 1% require extensive resuscitation  Always be prepared to resuscitate, even those with no risk factors will require resuscitation.
  4. 4. Assess baby’s risk for requiring resuscitation Provide warmth Position, clear airway if required Dry, stimulate to breathe Give supplemental oxygen, as required Assist ventilation with positive pressure Intubate the trachea Provide chest compressions Medications Always needed Needed less frequently Rarely needed
  5. 5. BEFORE BIRTH  Oxygen supply by placental membranes  No role of lungs. Fluid filled alveoli and constricted arterioles due to low Po2 in fetal blood.
  6. 6. AFTER BIRTH  Baby cries  takes first breath  air enters alveoli  alveolar fluid gets absorbed  increased Po2  relaxes pulmonary arterioles  decreased PVR
  7. 7.  Umbilical arteries constrict + clamp cord  closure of Umbilical Arteries and Umbilical Vein  increased SVR  Decreased PVR + Increased SVR  functional closure of Ductus Arteriosus  increased blood flow into lungs  oxygenation  supply to body through aorta.
  8. 8.  Low muscle tone  Respiratory depression (apnoea / gasping)  Tachypnea  Bradycardia  Hypotension  Cyanosis
  9. 9.  Provide warmth : Radiant warmer, don’t cover with towels.  Position head and clear airway as necessary  Dry and stimulate the baby to breathe, reposition
  10. 10.  Suction mouth first, then nose  “M” before “N”  To prevent aspiration of mouth contents
  11. 11. Stimulate : Flicking the soles/ drying & rubbing the back Evaluation
  12. 12.  Ventilation of the lungs is the single most and most effective step in newborn resuscitation Indications:  Gasping/apnea  HR < 100/min  SpO2 remains below target values despite free flow supplemental oxygen increased to 100%.
  13. 13. Appropriate Sizes  Mask should Rest on Chin Cover Mouth & Nose
  14. 14.  Gently pull infant’s jaw forward to mask  Use a “C-grip” to hold mask to infant’s face, using the 3rd finger to hold jaw up to mask
  15. 15. 40 to 60 breaths per minute Start With 21% ( higher in preterm's) oxygen and increase according to target Saturation Initial Pressure at 20mmH2O
  16. 16.  Most Important sign is the rising of HR  Improvement in Oxygen Saturation  Equal and adequate breath sounds B/L  Good Chest rise
  17. 17. If heart rate <100 bpm despite adequate ventilation for 30 seconds,
  18. 18. Corrective steps Action M Mask Adjustment Ensure Good seal of mask on face R Reposition airway Sniffing Position S Suction Mouth and nose If secretions present O Open mouth Ventilate with baby mouth slightly open and lift the jaw forward P Pressure increase Gradually increase the pressure every few breaths A Airway alternative Consider ET or Laryngeal mask airway
  19. 19. If heart rate <60 bpm despite adequate ventilation for 30 seconds,
  20. 20. Indications :  HR <60/min despite at least 30 sec of effective PPV Strongly consider Endotracheal intubation at this point as it ensures adequate ventilation and facilitates the coordination of ventilation and chest compressions
  21. 21. Rationale:  HR<60/min despite PPV indicates very low O2 levels and significant acidosis  depressed myocardium  no blood in lungs to get oxygenated(supplied by PPV)  Chest compressions + effective ventilation (ET/PPV)  oxygenation of blood  recovery of myocardium to function spontaneously  HR increases  O2 supply to brain increases
  22. 22. Technique:  Thumb technique: 2 thumbs depress the sternum, hands encircle the torso and the fingers support the spine. Preferred technique  2 – Finger technique: Tips of middle & index/ring finger of one hand compresses sternum, other hand supports the back.
  23. 23.  Thumb technique is preferred as  Better control of depth of compression  Can provide pressure consistently  Superior in generating peak systolic and coronary arterial perfusion pressure.
  24. 24. For small chests with thumbs overlapped
  25. 25. 2- finger
  26. 26.  Depth : 1/3rd of the anteroposterior diameter of chest.  Duration of downward stroke should be shorter than the duration of release  Do not lift the fingers off the chest
  27. 27. Coordination of chest compressions and ventilation:  Avoid giving compression and ventilation simultaneously  1 breathe after every 3 compressions  Ratio is 1 : 3 or 30: 90 per minute  One cycle: 2 sec, 3Compresssions + 1 ventilation  1 minute : 30 cycles or 120 events (90 compressions + 30 breaths)
  28. 28. When to stop chest compressions?  Reassess after 45-60 sec, if HR > 60/min stop chest compressions and increase breaths to 40-60 per minute. If HR is not improving…  Insert an umbilical catheter and give IV epinephrine
  29. 29.  WHEN TO CONSIDER INTUBATION ? Indications in resuscitation  Baby is floppy, not crying, and preterm  HR < 100/min, gasping/apnea  HR < 100/min inspite of PPV  HR < 60/min  No adequate chest rise and no clinical improvement  If chest compressions are needed, intubation provides better coordination and efficacy of PPV  To administer drugs
  30. 30.  Special conditions  Extreme Prematurity  Surfactant administration  Suspected diaphragmatic hernia
  31. 31. Mechanism of action :  Increases systemic vascular resistance  Increases coronary artery perfusion pressure  Improves blood flow to myocardium and restores depleted ATP Indications :  If HR remains < 60/min even after 30 sec of effective ventilation preferably after intubation and at least another 45-60 sec of coordinated chest compressions and effective ventilation
  32. 32. Administration :  Intravenous (recommended)  Endotracheal Preparation and dosage:  Adrenaline vial 1ml = 1mg (1:1000 solution)  Dilute with NS to make 1:10,000 solution (1ml = 100 mcg)  IV : 0.1-0.3 ml/kg = 10-30 mcg/kg  ET : 0.5 – 1 ml/kg = 50-100 mcg/kg  Give rapidly – as quickly as possible  Can repeat every 3-5 minutes
  33. 33. Indications:  Bradycardia not improving with adrenaline Volume Expanders:  Normal saline (recommended)  Ringer lactate  Dosage: 10 ml/kg  Route : Umbilical vein  Rate: over 5-10 min , rapid infusion may cause IVH in <30 weeks babies
  34. 34.  Additional resources , additional personnel, additional thermoregulation strategy  Portable warming pad  Polyethylene Plastic wrap (< 29wk)  Prewarmed transport incubator  Use of Oxymeter, blender to target Spo2 85%- 95%  Use Lower PIP 20-25 cm of H2O during PPV  Consider giving CPAP  Consider Surfactant
  35. 35.  Avoid hyperthermia, consider therapeutic hypothermia within 6 hrs for >36wks and Acute perinatal HIE  Monitor for Apnea, bradycardia, BP, SPo2 &Urine output.  Monitor B. Sugars, electrolytes, Hematocrit , Platelets, ABG  Maintain adequate oxygenation & support ventilation as needed
  36. 36.  Delay feeds, Start IV fluids, consider parenteral nutrition  Consider inotropes,fluid bolus  Ensure adequate ventilation before giving sodium bicarbonate(only in severe metabolic acidosis)
  37. 37.  Choanal atresia – oral Airway  Pierre Robin : place prone , 12F Et through nose with tip in post pharynx  Laryngeal web, cystic hygroma, Cong. Goiter- ET/tracheostomy  Pneumothorax : Percutaneous needle aspiration  Pleural effusion : Percutaneous needle aspiration  Congenital Diaphragmatic hernia
  38. 38.  Can we differ resuscitation?  Can we to stop resuscitation?
