Resuscitation of The Newborn Baby
The goal of resuscitation is :--To prevent morbidity & mortality associated with
hypoxic-ischemic tissue injury ( brain, heart, kidney), thiscan be achieved if adequate spontaneous respiration and
sufficient cardiac output can be re established early on.
Although the Apgar score is helpful in evaluating patients in need of attention, infants who are born limp, cyanotic, apneic, or pulseless require immediate resuscitation before assignment of the Apgar score.
Rapid and appropriate resuscitative efforts improve the likelihood of preventing brain damage and achieving a successful outcome.
About 5-10% of newborn babies require active intervention to establish
normal cardiorespiratory function.1- First of all the asphyxiated newborn baby should be put on a
resuscitation trolley where the baby put under a radiant heater toavoid hypothermia then drying up of the baby, the head is positioned
down & slightly extended, the airway is cleared by sucktioning, and
also gentle tactile stimulation provided (slapping the foot or rubbing
of the back).
If spontaneous respiration started and the cardiac output improved
where the color of the baby becoming pink, then there is no neednow to go onto further steps of resuscitation, but if these
measures fails to improve the condition of the baby and the heart rate
is < 100 /min so we need:-
2- Positive pressure ventilation with a 100% oxygen is given through a
tightly fitted mask & bag for 15-30 sec, subsequent breaths are givenat a rate of 40-60 /min with pressure of 15-20 cm water.
Successful ventilation is determined by good chest rise symmetric
breath sounds, improved pink color, heart rate of >100 /min,
spontaneous respiration and improved tone. If no response within
15-30 sec. the next step is:-
Ambu bag
3- Insert an endotracheal tube and start to push an oxygen through thetube by an ambu bag, if after 15-30 sec of doing that & the baby does
not improve (no spontaneous respiration, heart rate is < 100/min, no
improvement in the color of the baby, so the next step is:-
4- Starting chest compression (cardiac compression to improve
circulation) the compression is exerted to the lower third of thesternum at a rate of 120 per min. the ratio of compression to
ventilation is 3:1 simultaneously the color, the heart rate the
respiration and muscle tone should be assessed, if the baby did not
respond after 15- 30 sec of chest compression & oxygen supply
through an endotracheal tube then:-
5- An intravenous drugs are used after an insertion of an intravenous
(usually umbilical) catheter and as follows:-
- Epinephrine 1/10000 (0.1-0.3) ml/kg IV or intratracheal is given
for asystole or for failure to respond to 30 sec of combinedresuscitation and the heart rate is < 60/min, this can be repeated
every 5 min .
- Volume expanders 10 - 20 ml/kg of (normal saline, blood, 5%
albumine, or ringers solution) should be given for hypovolemia,pallor, E.M dissociation (weak pulses with noraml heart rate), history
of blood loss, suspicion of septic shock, hypotension or in poor
response to resuscitation.
- Sodium bicarbonate (1-2meq/kg) should be given slowly in case of
metabolic acidosis and resuscitation is prolonged.- Calcium gluconate (2-4 ml/kg of 10% solution) if there is evidence of
hypocalcemia.- Naloxone given in a dose of 0.1 mg/ kg repeated as needed when
there is CNS depression due to maternal narcotic analgesicadministration during labor which will results in respiratory depression
& failure to initiate spontaneous respiration.
- Dopamine or dobutamine may be given in a dose of 5-20 microgram /
kg/ min. this drug may be used in severe asphyxia when there is
depressed myocardial function.
• Poor response to ventilation during resuscitation may be due to:-
1.loosely fitted mask.2.Poor positioning of the endotracheal tube.
• 3.Intraesophageal intubation.
• 4. Airway obstruction.
• 5. Insufficient pressure.
• 6. Pleural effusions.
• 7. Pneumothorax.
8. Asystole.
9. Hypovolemia.
10. Diaphragmatic hernia.
11. Prolonged intrauterine asphyxia.
