2. Developmentally Supportive
Care - Introduction
• Initial premie care - intrauterine like
environment
• “Masterly inactivity”
• Based on three basic needs(FAT)
• Quiet nursery to busy / bustling stations
• Increasing survival of smaller babies
• Technology - oriented NB care.
• Optimal functional outcome more important

Past Present

5. NICU Environment -
Present Scenario
• Preterm babies with immature organ systems
• “Deprivation” or “Over-stimulation”
• Inappropriate pattern of stimulation
• Immature distance receptors (e.g.hearing &
vision) over stimulated.
• Mature tactile and vestibular pathways
under-stimulated.
• “Robotic” care
• No parental / maternal involvement

6. NICU Environment
Effect on brain development
(Gressens P, 2002)

7. “The genes are the bricks & mortar
to build a brain. The environment is
the architect” - Christine Hohmann

8. Developmentally supportive care
Definition : Developmentally supportive
care is defined as care of an infant to
support positive growth and
development, while allowing stabilization
of physiologic and behavioral functioning
(National Association of Neonatal Nurses,
2000)

• Management of pain
• Parental participation & support
• Neonatologist’ attitude

14. NICU Environment
Infant states
1. Quiet sleep - regular breathing, no REM, no
spontaneous movements.
2. Light sleep - irregular breathing, REM,
spontaneous movements.
3. Transition / drowsy - variable activity, dull look
4. Awake - alert - minimal activity, bright look.
5. Awake - hyperactive - very reactive, fussy,
increased motor activity.
6. Crying

15. NICU Environment
Signs of neonatal stability
Autonomic : Stable colour, stable
heart & RR, feeding tolerance.
Motor : Flexed or relaxed
posture, hand to mouth / sucking
State : Clear sleep state,
interaction
(Gupta G, 2001)

16. NICU Environment
Signs of neonatal stress
Autonomic : Color changes,
alterations in HR & RR,
alterations in SaO
2
, Hiccoughs
Motor : Hypotonic, increased
movements, open mouth
State : Hyperalert, fussing, diffuse
sleep states
(Gupta G, 2001)

17. NICU Environment – Sound
Adverse effects of loud sound
(>60 db)
Interferes with sleep
• Increase in Heart Rate
• Peripheral vasoconstriction
• Sudden loud noise may  TcPo2,
ICP, ? IVH
• Hearing loss
( Lefrak L, 2001)

18. NICU Environment - Sound
• In-utero, 40-60 db
• Usual noise levels in NICU, 50-80 db
• Levels > 90 db for long times, hearing loss
• In PT on aminoglycosides, at lower db levels

19. NICU Environment – Sound
Sources of Noise
• Inside incubater, 55-88 db (Peak 117)
• Additional 10-40 db with surrounding
equipments
• Routine care activities, 58-76 db.
• Loud, sharp sound - 100-200 db.
• 4994 peak noises - 90% due to human related
factors
(Chang et al, 2001)

20. NICU Environment – Sound
Interventions to reduce noise

•?  risk of ROP
( Slevin M, 2000 )

27. NICU Environment – Light
Light Reduction
Safe level not established
• Shade head of crib / incubator
• when required , use spot light /
procedure light
•Eye covers must with PT
• use available natural light

28. NICU Environment – Light
Light Reduction
Cycled lighting better than near Darkness
- More time in sleep state
-  weight gain
-  Motor activity levels
-  Heart rate

(Brandon HD et al, 2002).

• Prevent postural deformities
• Promote self-soothing activities
• Decided by GA, degree of illness,
paralytic agents.

32. NICU Environment –Positioning
Guidelines

Preferred, Prone / side lying
• Swaddle / cover to keep in flexed position
• Attempt to “nest” the infant
• Promote midline alignment
• Head support
• Avoid :
- Hyperextension of neck
- Frequent head turning to side
- Lower extremity frogging
- Bigger diaper

33. NICU Environment - Handling
• Physiologic and behavioral stress
• Pace the care according to baby
• Time the care around sleep / wake
cycles
• No routine procedure
• Provide 2-3 hrs of uninterrupted
sleep
• Watch for S/o stress

34. NICU Environment -
“Minimal Handling” or “Quiet hour” Protocol
• Reduce noise
• Reduce lights
• Allow minimum two hours of rest
• Cluster the caregiving procedure
• Sensitize the nursing staff

35. NICU Interventions - Stimulation
• Should begin in the womb.
• Fetuses known to respond to
mother’s heart beats and voice.
• Indian mythology - Abhimanyu learnt
to enter Chakaryuh in his mother’s
womb.
• Any stimulation through special
senses during fetal / neonatal life
beneficial

64. NICU Interventions - Goal

65. “The prematurely born infant emerges into a hectic,
cold, noisy and bright environment filled with
mysterious equipment and peopled by masked
strangers who try to help. Almost everything done
to or for the infant is painful, and that pain can be
certainly felt, although it can not be communicated.
The infant who must have an endotracheal tube
cannot cry and is not fed by mouth for weeks. His or
her feet are slashed periodically for blood samples.
The infant’s respirator roars away night and day,
keeping his or her lungs inflated and sustaining life
- but at what price ?”
Dr. Jerry Lucey, Editor of Pediatrics

66. Let us work to help newborns
