Statement of standard

Sleep of all infants is respected.

Rationale

Fetuses and infants spend most of their time sleeping. Sleep is crucial to early neurosensory and motor development. (1,2) Therefore, sleep protection for infants during neonatal care is a goal for parents and healthcare professionals. Sleep is a regulated process. Sleep-wake states can be observed only after the neuronal structures involved have developed sufficiently.

Sleep state identification and respecting the period of sleeping in preterm infants become essential because good sleep organisation in the infant is related to better developmental outcomes. Protecting sleep cycles is critical to preserve the brain’s ability to change, adapt and learn in response to experiences. (1) During sleep preterm infants are building their brain.

The neonatal unit environment has the potential to affect the quality and quantity of sleep (3) with disruption of brain development. (4)
It is important to encourage caregiving practices that preserve sleep, a non-invasive environment (5) focused on the infant’s individual needs and behavioural patterns, and help with the transition between the states. Kangaroo mother care has shown to be an important strategy, increasing sleep time and the amount of quiet sleep (6), and improving sleep-wake cycles. (7–9)

Getting started

Initial steps
For parents and family
  • Parents are verbally informed by healthcare professionals about the importance of sleep during care.
  • Adjust care to the sleep-wake rhythm of the child.
For healthcare professionals
  • Attend training on the importance of sleeping during infancy and recognise sleep-wake cycles in term and preterm infants.
  • Coordinate between different healthcare professionals of different specialties in order to protect the infant’s sleep.
  • Adjust care to the sleep-wake rhythm of the child.
For neonatal unit
  • Develop and implement a unit guideline on sleep protection.
  • Develop information material on the importance of sleep during care for parents.
  • Organise training sessions for caregivers explaining the importance of respecting sleeping period for the infant brain development and the unit policy or guidelines.
  • Provide protocols within meetings between all hospital specialities related to care in order to protect sleep to evaluate cooperation.
For hospital
  • Support healthcare professionals to participate in training on the importance of sleeping during infancy and recognise sleep-wake cycles in term and preterm infants.
For health service
  • Develop and implement a national guideline on sleep protection.
 

Description

Infants have a different sleep pattern to older individual. During infancy, there are three types of sleep: (3)

Active sleep (AS)
Irregular sleep in which the electrical activity is like the waking state. Rapid eye movement under the eyelids, irregular heartbeat and breathing are present. This type of sleeping represents 50% of newborn at term.

Quiet sleep
The body is relaxed, there is no eye movement, and the heartbeat and breathing are regular, the parasympathetic system predominates. The muscles are relaxed but there may be movement.

Undetermined sleep
It is difficult to identify, as it is neither one nor the other: characteristic of preterm infants, who have their brain in continuous development.

During active sleep there is an endogenous intense and generalised stimulation, AS might play the role of stimulation to the brain in a period when waking life is limited. Mainly, AS is associated with the development of the sensory systems and it is necessary to form long-term circuits related with memory and learning. Quiet sleep plays an important role in the synaptic remodelling, in tissue repair and recovering from illness, as well as growth. (4)
