NPASS: The Neonatal Pain, Agitation, and Sedation Scale

A

considers the previous criteria, in addition to behavior, and is considered to be a very reliable and valid assessment tool, even for premature infants on ventilators.

Scores are given for crying or irritability, behavioral state, facial expression, tone of extremities, vital signs, and oxygen saturation

Scores in each category range from -2 for sedated infants to +2 for agitated infants.
A normal response indicating no pain or sedation is scored as 0 (zero).

89
Q

decrease the risk of SIDS

A
  • Infants must be placed on their back to sleep (for all sleep)
    • Infants should not be exposed to tobacco smoke, before and after birth
    • Infants should sleep in a crib, cradle, or bassinet that meets current Canadian Safety Association (CSA) standards.
    • Pillows, stuffed animals, bumper pads, and blankets should not be placed in the crib of the newborn.
    • Infants should not be overdressed, or overheated by blankets, as this increases the risk for SIDS.
    • Infants should share a room (but not bed) with a parent or caregiver for 6 months.
    • Breastfeeding provides some protection for newborns from the risk of SIDS.
    • Pacifiers appear to provide a protective effect for SIDS. Their use does not seem to impair breastfeeding; however, delaying the introduction of a pacifier is best left until breastfeeding is well established.
    • Bed sharing is when a newborn sleeps on the same sleeping surface, such as an adult bed, sofa, or arm-chair, as that of an adult or another child. Sharing a sleeping surface increases the risk of SIDS. The risk is particularly high for infants less than 4 months of age. Thus bed sharing is not recommended.
90
Q

CPS safe swaddling guidelines

  • Don’t overdress the baby. Use light blankets so the baby doesn’t overheat.
  • Stop swaddling when the baby shows signs of rolling over.
  • Make sure the baby’s nose and mouth are not covered.
  • Make sure the baby can still move their legs, to avoid hip dysplasia (an abnormality of the hip joint where the socket does not fully cover the ball portion, which can increase the risk for dislocation).
