Newborn resuscitation

 

  • Most newborn babies don't need resuscitation — but always be ready
  • If resuscitation needed — most babies only need Airway and Breathing support. Performed quickly these can prevent need for circulation support
  • Bag-valve-mask resuscitation almost always successful if performed correctly — can be done for several hours while waiting to send to hospital
  • Keep baby warm and dry but do not overheat — can depress respiration

Steps of resuscitation

  • D – Dry and stimulate to get a response
  • R – Response from baby - rapid assessment of breathing effort, heart rate, tone
  • S – Send for help
  • A – Airway — open and clear, sniffing or neutral position
  • B – Breathing — positive pressure bag-valve-mask ventilation
  • C – Circulation — chest compressions while continuing ventilation
  • D – Drugs — give adrenaline (epinephrine) or fluid
  • Reassess breathing effort, heart rate and tone every 30 seconds to decide whether to progress to next step

Improvement in baby’s condition are indicated by

  • Spontaneous breathing
  • Increasing heart rate
  • Improving tone

Do — before birth

  • Call for help 
  • Warm room — close doors and windows to stop drafts or open doors and windows if air conditioner can't be turned off
  • Get equipment ready and check it is working
  • Identify flat surface for assessment and resuscitation if needed. Cover with towels if surface cold
  • Try to get as much antenatal information as possible

Do — at birth

D – Dry stimulate baby with warm towel. Discard wet towel and cover baby in a clean warm towel. Cover baby's head

R – Response — Rapid assessment

  • Breathing or crying
  • Heart rate more than 100 beats/min — listen with stethoscope
  • Good muscle tone

If answer is NO to ANY sign in rapid assessment — baby needs more help

  • Have helper do urgent medical consult
    • If doctor not on site — stay on phone
  • Follow the steps below or see — Newborn resuscitation flowchart
    • Assess breathing effort, heart rate and tone every 30 seconds
    • Use results to guide progress through following steps or flowchart

If answer YES to ALL signs in rapid assessment — see Newborn care

Clamp and cut cord if needed

  • Put 2 metal clamps on cord 5cm apart and at least 10cm from baby’s abdomen — Figure 1.7
  • Cut cord between the 2 clamps with sterile blunt-end scissors
  • Do not take clamps off after cutting

Figure 1.7  

Cord is cut midway between metal clamps.

A – Airway

Establish an airway

  • Put baby on flat, dry surface
  • Put baby’s head in sniffing/neutral position to open airway — Figure 1.8
    • Small towel under shoulders helps maintain position
    • Do not tip head forward — Figure 1.9 or too far back — Figure 1.10

Figure 1.8     

Infant with head in neutral position has trunk and shoulders supported on a towel.

Figure 1.9   

Chin on chest indicates head too far forward.

Figure 1.10   

Chin in air indicates head extended too far.

  • Clear airway as needed
  • If obvious signs of obstruction gently suction mouth then nose with 10–12F catheter for 5 seconds
  • Reposition baby’s head to open airway
  • Recheck breathing effort, heart rate, tone
  • Continue to follow steps below or see — Newborn resuscitation flowchart

B – Breathing

Ventilation is the most effective action in newborn resuscitation — make sure assisted ventilation effective before continuing to circulation or see — Newborn resuscitation flowchart

If baby is not breathing effectively — bag-valve-mask ventilation at 40–60 breaths/min

  • Start with room air for both term and preterm babies
  • Check baby’s head in sniffing/neutral position — Figure 1.8
  • Mask should cover nose and mouth —  Figure 1.11
  • Need good seal between mask and face — Figure 1.12. Check for chest wall movement with each inflation — best indicator that mask is sealed and lungs are being inflated
  • Put O2 sats probe on baby's right hand or wrist
  • After 30 seconds  — check breathing effort, heart rate, tone
  • If no improvement after 30 seconds of effective ventilation — change from room air to oxygen at 10L/min

Figure 1.11   

Oxygen mask is positioned on baby's face from bridge of nose to chin, covering mouth and nose.

Figure 1.12   

Oxygen mask held securely on baby's face with one hand, using thumb and index finger, bag attached.

If chest not rising with each squeeze of bag — check for

  • Poor seal - reapply mask to face to make better seal
  • Blocked airway
    • Reposition head
    • If obvious signs of obstruction — gently suction mouth then nose with 10–12F catheter for 5 seconds
  • Enough inflation pressure being used - squeeze bag more firmly to get an easy rise and fall of chest

C – Circulation

If heart rate less than 60 beats/min after 30 seconds of effective ventilation — continue bag-valve-mask ventilation with oxygen at 10L/min and start chest compressions

  • Use 2 thumbs on lower third of sternum with fingers around chest — Figure 1.13 — best for 2-person resuscitation 
    • Thumbs side-by-side or overlap for small baby

OR 2 fingers along sternum at right angle to chest — Figure 1.14 — best for single person resuscitation

    • Can hold mask on with other hand — tuck bag under same arm
  • Depth — 2–3cm (⅓ depth of chest) — Figure 1.15
  • Ratio — 3 compressions to 1 breath
  • Rate — 90 compressions + 30 breaths/min
  • Leave space for each breath

Figure 1.13   

Grasp baby's chest loosely with both hands, apply compressions through the sternum with both thumbs.

Figure 1.14   

Use extended index and middle finger directly over sternum.

Figure 1.15   

Press straight down until chest is compressed by about one third.

  • Use this rhythm in a 2 second cycle
    • One-and-two-and-three-and-breath-and-one-and-two-and-three-and-breath-and … — Figure 1.16

Figure 1.16   

Infant CPR rhythm for 2 second cycle.

If heart rate 60–100 beats/min — continue bag-valve-mask ventilation

If heart rate more than 100 beats/min, breathing 40 breaths/min or more and tone improving — put baby on mother's chest skin-to-skin

  • If central cyanosis — give free flow oxygen
  • See — Newborn care

If baby not improving

If heart rate less than 60 beats/min — usually ineffective ventilation (not enough oxygen)

  • Continue bag-valve-mask ventilation and chest compressions
  • Review resuscitation technique
    • Is chest movement adequate — recheck seal, airway, inflation pressure
    • Check oxygen is connected to bag-valve-mask at 10L/min
    • Are chest compressions ⅓ depth of chest
    • Are chest compressions and ventilation well-coordinated

D – Drugs

  • If heart rate still less than 60 beats/min — continue chest compressions with bag-valve-mask ventilation
  • Medical consult
  • Give adrenaline (epinephrine) and fluids as directed by doctor
    • Be ready to put in IV cannula or intraosseous needle as directed by doctor
    • Adrenaline (epinephrine) IV/intraosseous 0.01-0.03mg/kg (0.3mL/kg of 1:10,000 solution) followed by a small normal saline flush every 3-5 minutes — repeat every 3-5 minutes if heart rate less than 60 beats/min despite effective ventilation and chest compressions

Ongoing resuscitation

  • If prolonged bag-valve-mask ventilation needed — get helper to put in nasogastric tube, if skilled
    • Stop ventilation for as short a time as possible
    • Suction gastric contents, secure tube, leave tube on free drainage (unplugged)
    • Reposition baby’s head and restart ventilation
  • If no heartbeat after 15 minutes of resuscitation — medical consult about stopping resuscitation — outcome for baby is always poor 
  • Talk with mother and family and explain situation

Pulse oximetry

  • Use O2 sats probe, if available
    • When starting positive pressure bag-valve-mask ventilation
    • If giving oxygen
    • If persistent cyanosis suspected
  • Put probe on baby's right hand or wrist
  • See — Table 1.1 for target O2 sats
    • O2 sats for normal newborns can take up to 10 minutes to rise above 90%
  • If O2 sats reach 90% — gradually reduce amount of oxygen being given
  • If O2 sats falling or less than 90% after 10 minutes — specialist consult

Post-resuscitation care

Babies who need full resuscitation have been severely stressed — monitor closely while waiting for evacuation

  • See — Newborn care for monitoring and ongoing care
  • Continue oxygen unless directed by doctor to stop
  • Maintain baby's temperature between 36.5 and 37.5°C — see Keeping baby warm after birth
  • Check baby's blood glucose level
  • Put in nasogastric tube, if skilled and directed by doctor
    • Size 6F for very small babies, size 8F for bigger babies
    • Leave tube on free drainage (unplugged) to let out air in stomach (from bag-valve-mask ventilation)
  • Baby may need fluid or medicines — be ready to put in IV cannula or intraosseous needle as directed by doctor
