Start with the truth this whole chapter stands on: pain is subjective and individualized — it is whatever the child experiences it to be, and no two children experience the same injury the same way. Infants and children of all ages experience pain, including newborns and premature infants. The catch is that young children may be unable to describe pain verbally — a baby can't say "it hurts here, and it's a seven out of ten." That doesn't mean the pain isn't there; it means the nurse has to read it from behavior and body signs instead.
Why does this matter so much? Because untreated pain has physical, emotional, and developmental consequences — pain that is ignored changes how a child heals, how they respond to future care, and how they develop. That's why effective pain management is never a single action; it's a cycle: assess, intervene, and reassess.
Exams love classification questions, and each type here is defined by where the pain comes from or how long it lasts.
Two children with the identical injury can hurt very differently, because pain is filtered through the child. The influencing factors: age and developmental level, cognitive ability and understanding of pain, temperament and coping skills, previous painful experiences, family responses and cultural influences, and anxiety, fear, and perceived loss of control. This is why the nurse assesses the whole child — a frightened child who had a bad needle experience last year will feel today's blood draw more intensely than a calm child having their first one, and both reports are real.
Neonates (newborns in the first month of life) — including premature infants — experience pain. Since they can't report it, pain shows up as: facial grimacing or tightly closed eyes, a high-pitched cry, body stiffening or withdrawal, and changes in heart rate, respiratory rate, or oxygen saturation (the percentage of oxygen in the blood). It also leaks into daily life: irritability, poor feeding, disturbed sleep. The rule for this age: physiologic and behavioral indicators must be assessed together — neither one alone tells the whole story.
Toddlers react big and physical: crying, screaming, kicking, or physical resistance. They may point to the painful area, cling to parents, and show regression (going backward to earlier behaviors, like losing a toilet-training skill) or other behavior changes. Preschoolers are trickier — some hide, withdraw, or become quiet instead of crying, so a silent preschooler is not a comfortable one. They may associate pain with punishment (magical thinking: "I was bad, so this happened"), but they can identify pain location using simple language and may use faces scales if developmentally appropriate.
School-age children have an increasing ability to describe location, intensity, and quality of pain — real self-report becomes possible. But watch the trap: they may attempt to appear brave and underreport, and they may fear loss of control or additional procedures ("if I say it hurts, they'll do something worse"). The upside: they can participate in selecting pain-relief strategies, which increases their sense of control.
Adolescents are usually capable of detailed self-report — the most reliable reporters of all. Yet they may minimize pain to maintain independence, and they're concerned about privacy, body image, and peer perceptions. They benefit from direct involvement in treatment decisions — treat them as partners, not bystanders.
Assessment follows clear rules. Use a validated, developmentally appropriate pain scale — validated means the tool has been tested and proven to measure pain reliably in that population. Self-report is preferred when the child can communicate reliably — the child's own number beats your guess every time. Assess the full picture: location, intensity, duration, and characteristics (and quality — what it feels like). Observe behavioral and physiologic indicators, and include parents' observations of changes from baseline — nobody knows what "normal" looks like for that child better than the parent. Finally, reassess after interventions using the same tool — switching scales mid-stream makes scores impossible to compare.
This is the most testable table in the chapter. Each scale exists because a different group of children can't use the others.
Nonpharmacologic strategies — comfort measures that don't involve medication — are not "extras"; they are real interventions, and they pair with medication rather than replacing it. The toolkit: distraction (toys, music, games, videos), positioning, swaddling (wrapping an infant snugly), and comfort measures, parent/caregiver presence, relaxation, guided imagery (leading the child through calming imagined scenes), and breathing techniques, and preparation with developmentally appropriate explanations. For selected neonatal procedures: skin-to-skin care, breastfeeding, or sucrose (a small amount of sugar water given orally, which calms infants during brief procedures).
Match the approach to the stage: infant — swaddling, holding, skin-to-skin, breastfeeding · toddler — parent presence, comfort objects, distraction · preschooler — simple explanations, play, bubbles, limited choices · school-age — preparation, participation, relaxation techniques · adolescent — privacy, autonomy, detailed explanations, coping choices.
Medication selection is individualized; it depends on pain severity and cause, age and weight, clinical condition, and route of administration (how the drug is given — by mouth, IV, and so on). The ladder is simple: nonopioid analgesics (pain-relieving drugs that are not opioids) for mild to moderate pain; opioids may be required for moderate to severe pain. Best practice is multimodal management — combining medications with nonpharmacologic interventions so each covers what the others miss. And always: reassess effectiveness and adverse effects.
Opioids may be indicated for moderate to severe pain — remember the myth table: they are not forbidden in children. Common oral examples: morphine and oxycodone. They are dosed with individualized pediatric dosing (calculated for that child, by weight), and the safety rule is lowest effective dose for the shortest appropriate duration.
Pediatric dosing is weight-based, which makes these checks non-negotiable: verify the current weight in kilograms (pediatric doses are calculated per kilogram — a pounds-versus-kilograms mix-up can double or halve a dose), calculate and verify the weight-based dose, and confirm maximum individual and daily doses. For liquids: use oral syringes (marked syringes designed for measuring medicine) and never household spoons — a kitchen teaspoon is not a measured 5 milliliters. Check allergies, contraindications, and previous doses, then document and reassess the medication response.
Procedures are a major pain source, so plan ahead: anticipate pain associated with procedures rather than reacting to it. Use topical anesthetics (numbing medicine applied to the skin) when appropriate, combine analgesia with distraction and comfort techniques, encourage parental presence when appropriate, minimize repeated painful procedures, and assess pain before, during, and after the procedure.
Know the four levels of numbing and sedation: local anesthesia numbs a specific area · regional anesthesia blocks sensation in a larger region of the body · general anesthesia produces unconsciousness for procedures or surgery · procedural sedation reduces anxiety, discomfort, and/or awareness while the child remains responsive. Procedural sedation requires appropriate monitoring and trained personnel.
The cycle closes with evaluation. Reassess using the same appropriate pain scale — same tool, comparable numbers. Judge more than the score: pain relief, activity and comfort, sleep and rest, feeding or oral intake, and medication adverse effects. If relief is inadequate, modify the interventions — don't just document failure and move on. Document the response and the caregiver's observations, because the parent often sees improvement or decline before the chart does.
