New Born Care Flashcards
Initiation of breathing
Factors that influence the first breath
Physical examination
Oxygen deprivation and carbondioxide accumulation
Thoracic compression
Initiation of breathing
After the delivery, the residual alveolar fluid is cleared through the
Pulmonary circulation and
Pulmonary lymphatics
Initiation of breathing
Delay in fluid removal from alveoli cause
Transient Tachypnea of the new born
Initiation of breathing
With the fall in pulmonary arterial blood pressure
Ductus Areteriosus normally closes
Initiation of breathing
Required to bring about the initial entry of air into the fluid-filled alveoli.
High negative intrathoracic pressures
Initiation of breathing
Normally, from the first breath after birth
More residual air accumulates in the lung
Initiation of breathing
Respiration is similar to those of the adult
5th breath
Initiation of breathing
Surfactant synthesized by
Type 2 pneumocytes
Initiation of breathing
Insufficient surfactant common in
Preterm infants leads to RDS
Care in the delivery room
Reverse the effects of opioids
Naloxone
Care in the delivery room
Percent of newborn require some degree of active resuscitation to stimulate breathing
10%
1% require extensive resuscitation
Care in the delivery room
Newborn delivered at home and those delivered in hospital
Two to three fold risk of death
Care in the delivery room
A fall in heart rate
Loss of neuromascular tone
Primary apnea
Care in the delivery room
Primary apnea treatment
Simple stimulation
Exposure to oxygen
Care in the delivery room
Primary apnea. If persist it continue to develop
Deep gasping respiration followed by
Secondary apnea
Care in the delivery room
A further decline in heart rate
Falling blood pressure
Loss of neuromascular tone
Deep gasping respiration
Secondary apnea
Care in the delivery room
Secondary apnea will not respond to
Stimulation,
Death follows unless ventilation assisted
Care in the delivery room
The vigorous newborn is first placed in a
Warm environment
Airway cleared
Infant dried
Care in the delivery room
Non beneficial and harmful
Routine gastric aspiration
Care in the delivery room
For clear or Meconium stained fluid is not beneficial, even if the newborn is depressed
Bulb suctioning
Care in the delivery room
Breath
Cray
Few seconds
Half a minute
Assessment at 30 seconds of life
These should prompt administration of positive pressure ventilation with room air
Heart rate is
Assessment at 30 seconds of life
Assisted ventilation rates of ________ are commonly employed
30-60bpm
Assessment at 30 seconds of life
Percent of oxygen saturation is monitored by
Pulse oximetry
Assessment at 30 seconds of life
Adequate ventilation is indicated by
Improved heart rate
Assessment at 60 seconds of life
HR remains
Ventilation is inadequate
Head position should be checked
Secretions cleared
Inflation pressure increased
If HR persist below 100 bpm beyond 60 seconds
Tracheal intubation is considered
If bag and mask ventilation is ineffective or prolonged
Tracheal intubation
Other indication of tracheal intubation
Chest compression
Tracheal administration of epinephrine
Tracheal intubation
Special circumstances such as
Extremely low birthweight
Congenital diaphragmatic hernia
Tracheal intubation
Sizes
0 for a preterm infant
1 for a term neonat
Tracheal intubation
Procedure
Laryngoscopes with a straight blade is introduced at the side of the mouth and then directed posteriorly at the
Oropharynx
Tracheal intubation
Procedure 2nd step
Moved gently to
Vallecula
Tracheal intubation
Space between the base of the tongue and epiglottis
Vallecula
Tracheal intubation
Tube size
- 5-4 mm term
2. 5 mm
Tracheal intubation
To ensure that the tube is positioned in the trachea and not the esophagus
Observation for
Symmetrical chest wall motion
Tracheal intubation
To ensure that the tube is positioned in the trachea and not the esophagus
Auscultation for
Equal breath sounds
Tracheal intubation
To ensure that the tube is positioned in the trachea and not the esophagus
No longer recommended
Trachea suctioning
Tracheal intubation
To ensure that the tube is positioned in the trachea and not the esophagus
Puffs of air are delivered into the tube at
1-2 seconds interval
Tracheal intubation
To ensure that the tube is positioned in the trachea and not the esophagus
Pressure
Term- 30-40cm H2O
Preterm 20-25cm H2O
If heart rate is remains
Chest compression
Chest compression
Delivered on the
Lower third of the sternum
Chest compression
Compression ventilation ratio

Chest compression

To achieve approximately
120 events/min
Chest compression

Chest compression are continued until the spontaneous heart rate is
Atleast 60bpm
Indicated when heart rate remains

Epinephrine and volume expansion
Epinephrine May be given through
Endotracheal tube
Epinephrine and volume expansion
Epinephrine
If venous access has not been established
IV dose is 0.01-0.03mg/kg

APGAR score
APGAR
The total score is determined in all neonates at
1 and 5 minutes after delivery
APGAR
If depressed infants the score may be calculated at
5 minutes interval until a 20 minute APGAR
APGAR
Score reflects the need for immediate resuscitation

APGAR
Measures effectiveness of resuscitative efforts and also has significance for neonatal survival
