  • Sensory nerve terminals exist on all body surfaces by 22–29 wk of gestation.

++

  • Pain assessment should be performed using validated tools in all patients upon admission and then at regularly defined intervals.
  • Physiologic responses to pain include increased circulating levels of catecholamines, increased HR, and increased BP.

++

  • Repeated or long-term painful stimuli result in long-term changes such as a lowered pain threshold.

++

  • Response to painful stimuli contribute to physiologic disturbances such as hypoxia, hypercarbia, acidosis, and hyperglycemia; this may lead to alterations in oxygen delivery and cerebral blood flow.

++

  • Infants have long-term disturbances in pain perception that persist well into childhood.

++

  • An absence of behavioral or physiologic cues that might indicate pain does not indicate an absence of pain.

++

Behavioral Measures

++

  • Swaddling: Keeping the extremities flexed and close to the trunk

++

  • Pacifiers: Used for non-nutritive sucking

++

  • “Kangaroo care”

++

  • Developmentally appropriate care

++

  • Minimize noise and light stimuli

++

Opioid Analgesics

++

  • Morphine
    • Intermittent IV dosing: 0.05–0.1 mg/kg/dose Q3–4h
    • Intermittent PO dosing: 0.2–0.5 mg/kg/dose Q4–6h
    • IV continuous infusion: Initial: 0.01–0.02 mg/kg/h
    • All dosing should be titrated to effect
  • Fentanyl
    • Intermittent IV dosing: 1–2 mcg/kg/dose Q2h
    • IV continuous infusion: 1–5 mcg/kg/h
    • All dosing should be titrated to effect

++

See chapter 2.

++

  • For minimally invasive procedures, combinations of a pacifier, swaddling, or sucrose can be used.
    • Arterial or venous puncture, or heelstick
    • Peripheral IV placement
    • Umbilical arterial or venous catheter placement
    • Endotracheal suctioning

++

  • The above measures plus topical anesthetic (see chapter 2 for listing and precautions of ...
