A Systematic Approach to Management of Abdominal Pain in Preverbal and Nonverbal Children in the Emergency Department
What ED Clinicians Need to Know
Acute abdominal pain accounts for a substantial proprtion of pediatric ED visits, and preverbal and nonverbal children are the patients most likely to have pain that is missed, underestimated, or undertreated. Because these children cannot describe their symptoms, they are at increased risk for delayed or missed diagnosis and are more likely to present with advanced surgical pathology. This issue reviews how to assess abdominal pain using behavioral measures, facial expressions, and body language; how to select the pain assessment tool best suited to the individual patient; and how to partner effectively with parents and caregivers without excluding the child.
The issue also provides recommendations for a graduated approach to pain management, including nonpharmacologic measures, nonopioid analgesics, opioid medications, and anxiolysis and sedation, along with guidance on routes of administration. It addresses misconceptions including the idea that analgesia “masks” pain and interferes with diagnosis.
Why This Topic Matters in the ED
- Pain in children is chronically undertreated, and undertreatment is even more pronounced in infants and other preverbal or nonverbal patients who cannot advocate for themselves.
- Untreated pain in childhood is linked to lasting effects on development, future healthcare experiences, and chronic pain.
- There is no single gold-standard pain scale for preverbal and nonverbal children, so clinicians must combine behavioral observation, physiologic markers, parental insight, and careful physical examination.
- Parents and caregivers can be expert advocates or can unintentionally detract from the encounter; a structured approach to incorporating their input leads to a more accurate picture of the complaint.
- Fear regarding administration of opioids and concerns about interfering with diagnosis continue to drive inadequate analgesia, despite evidence that early, deliberate pain control facilitates, rather than hinders, evaluation.
Clinical Content at a Glance
Clinical Q&A
- What makes pain assessment different in preverbal and nonverbal children?
- These patients are almost entirely dependent on caregivers and clinicians to identify the presence of pain and interpret its quality and severity. Assessment relies on behavioral cues (eg, motor activity, communication patterns, and facial expression) interpreted in the context of the child’s baseline, developmental stage, and any disability.
- Which pain assessment tools are available?
- No single scale is the gold standard. Self-reported scales suit older, verbal children, while behavioral scales, from neonatal tools to versions adapted for neurodivergent patients, fill the gap, each with defined age ranges, strengths, and limitations to consider when choosing the best fit for the patient.
- What role should parents and caregivers have?
- Parents know the child’s baseline better than anyone, but they can support or unintentionally hinder the encounter. A structured approach works best: involve the parents at the beginning of the encounter for input on the best approaches to their child, communicate directly with the child without interjection, and then cross-reference the information that was gathered.
- When are laboratory studies and imaging indicated?
- The threshold for workup differs for verbal and nonverbal children, whose differential is almost always broader. Certain historical and physical examination findings point toward a surgical etiology and should prompt workup, with ultrasound as the first-line imaging modality and computed tomography or rapid magnetic resonance imaging reserved for select situations.
- How should pain be managed?
- A graduated, step-up approach works best: nonpharmacologic measures and nonopioid analgesics first, escalating to ketamine, opioids, or anxiolytics when pain is not adequately controlled, with the route of administration matched to the patient and family input on the best way to give medications.
Case Snapshots
CASE 1 — Increased Fussiness in a 14-Month-Old: A well-appearing girl presents after a night of hourly screaming. She winces intermittently during the visit and has dark, sticky stools attributed to spinach. The issue discusses what further assessment is needed when the examination is benign but the history raises questions.
CASE 2 — Fever and Vomiting in a 3-Year-Old: A boy with a flat affect has rebound tenderness and guarding concerning for appendicitis. The surgical resident asks that pain medication be withheld to avoid “interfering with examinations.” The issue explores how to manage his pain while the surgical evaluation proceeds.
CASE 3 — Nonverbal Autistic Boy With Abdominal Pain: An agitated 8-year-old boy presents with dark, foul-smelling urine and lower abdominal pain. His mother shares his sensory preferences and past hospital experiences. The issue considers how to treat the boy’s agitation and pain while preserving patient and parent rapport.

Risk Management Pitfalls
- Underestimating pain when a child does not exhibit typical pain behaviors
- Rushing the examination instead of incorporating parents’ knowledge of a neurodivergent child’s needs
- Withholding pain medication because of concerns it will interfere with evaluation and diagnosis
- Attributing infant lethargy to a nonabdominal cause without ruling out intussusception
- Examining a patient in a chair rather than a recumbent position and missing conditions requiring intervention
