Child Abuse

Missed inflicted injury can lead to recurrent, more severe harm, including fatal head trauma. The ED must protect the child while preserving a careful, objective medical evaluation.

A 7-month-old girl arrives after her father reports that she “rolled off the couch.” Her left arm rests against her chest, and she cries sharply whenever anyone reaches toward it. The bruising on her cheek is faint, while the story changes from “she was fine” to “she may have been sleepy” during questioning. Her next examination and safety decision have not yet been made.

What must happen before this child leaves the department?
Which occult injuries require screening even when the child looks well?

When to Think of It

Entertain abuse when the history is inconsistent, changes with retelling, is developmentally impossible, lacks an appropriate witness, or does not explain the injury. Red flags include bruising in a nonmobile infant, bruises on the torso, ears, neck, or frenulum, patterned injuries, burns with sharp borders, multiple injuries in different healing stages, posterior rib fractures, metaphyseal lesions, intracranial injury without adequate trauma, and delay in seeking care.

Sick or Not Sick

The key call is whether the child can safely return to the current caregiver. Any concern for immediate danger, serious injury, unreliable supervision, or caregiver access to the suspected perpetrator requires hospital protection, social work/child-protection involvement, and usually admission or placement planning.

The First Fifteen Minutes

Any child with airway, breathing, or circulation compromise: initiate pediatric trauma resuscitation, oxygen and monitoring; obtain IV/IO access because occult multisystem injury may be present.
Hemorrhagic shock: balanced crystalloid 10 mL/kg IV/IO, reassess, then packed RBCs 10 mL/kg IV/IO if ongoing shock or major blood loss; blood restores oxygen-carrying capacity rather than diluting clotting factors.
Suspected opioid toxidrome with hypoventilation: naloxone 0.1 mg/kg IV/IM/IN, maximum 2 mg per dose, repeat every 2–3 minutes as needed; it reverses opioid-mediated respiratory depression. (Use local pediatric protocol for infants and concentrated products.)
Painful injury after life threats are addressed: acetaminophen 15 mg/kg PO/IV every 6 hours, maximum 75 mg/kg/day; it treats pain without impairing the neurologic examination. Avoid NSAIDs when significant bleeding, renal injury, or intracranial hemorrhage is possible.
Do not confront the caregiver or conduct repeated accusatory interviews; separate interviews and a neutral, verbatim history preserve safety and evidence.

Definitive Care & Disposition

Perform a complete undressed examination with a chaperone, document body diagrams and measurements, and photograph injuries according to institutional policy. Involve the child-protection team, social work, and the mandated reporting pathway; report reasonable suspicion rather than waiting for proof. Obtain skeletal survey in children younger than 24 months when abuse is suspected; repeat it in approximately 2 weeks when indicated. Head CT is urgent for altered mental status, seizures, vomiting with concerning findings, neurologic signs, or suspected abusive head trauma; MRI follows when stable. Consider CBC, coagulation studies, metabolic panel, lipase/transaminases, urinalysis, and targeted bleeding-disorder testing. Admit when injury is significant, the evaluation is incomplete, or safe disposition is unavailable; discharge only after a multidisciplinary safety plan confirms a safe caregiver and follow-up.

How This One Kills

The lethal failure is accepting a benign explanation for a nonspecific symptom—such as sleepiness, vomiting, or irritability—and discharging an infant with occult abusive head trauma back to the suspected perpetrator.

The Differential — What Else Looks Like This

Accidental bruising — bruises over bony prominences in a mobile child with a consistent mechanism; confusing it with abuse can cause unnecessary disruption, while missing abuse risks recurrent injury.
Bleeding disorder — diffuse bruising or abnormal screening studies with a compatible family history; assuming abuse alone can delay treatment, while attributing sentinel bruises to hemophilia can miss inflicted trauma.
Osteogenesis imperfecta — characteristic bone fragility, blue sclerae, and family history; confusing it with abuse can derail care, but it does not explain every soft-tissue or intracranial finding.
Infection or metabolic disease — fever, systemic illness, or laboratory abnormalities; mistaking it for trauma delays disease-specific treatment.

The Second-Day Story

Infants rarely provide a history, and serious injury may present only as poor feeding, vomiting, lethargy, apnea, or “not acting right.” Bruising may be absent despite intracranial injury, and a partially treated or delayed presentation can erase obvious findings. Developmental capability, caregiver timeline, serial neurologic examinations, careful skin inspection, and a low threshold for multidisciplinary evaluation recover the signal.

Back to Our Patient

Back to the 7-month-old girl: the developmental history makes an unobserved “roll off the couch” less reassuring, and the changing story plus arm pain and facial bruising trigger recognition of possible inflicted injury. She is currently perfusing and breathing normally, so the immediate fork is not airway rescue but whether she can safely leave—it is no, because the history is unreliable and the alleged mechanism is inadequate. During the first fifteen minutes, the team monitors her, obtains access, performs a gentle complete examination, treats pain with weight-based acetaminophen, and avoids repeated questioning. Child protection and social work are engaged, a skeletal survey and targeted head evaluation are arranged, and she is admitted while a safe disposition is established.

Patient Presentation to Attending

How you’d present this patient on the floor — tight, pertinent positives and negatives, no rambling

“This is a 7-month-old previously healthy girl brought for left arm pain after her father reports she rolled off a couch, with a changing history and no witnessed event. She is alert with normal perfusion and respirations but cries with left arm movement and has a faint cheek bruise; there are no reported seizures, vomiting, or loss of consciousness, though the history is unreliable. The mechanism is developmentally and biomechanically concerning, and the combination of a nonmobile infant, unexplained extremity pain, and bruising raises concern for inflicted injury. I plan continuous monitoring, a complete undressed examination with documentation, weight-based acetaminophen, skeletal survey, targeted head imaging and screening labs as indicated, and immediate child-protection and social-work consultation. She should be admitted until occult injury is excluded and a safe disposition is confirmed.”

Study Directive

Memorize the TEN-4-FACESp bruising regions and age threshold.
Practice a neutral abuse history using open-ended questions, then write one objective injury description with measurements.
Review local mandated-reporting and child-protection consultation procedures.
Complete five pediatric abuse imaging questions, including when to obtain skeletal survey and neuroimaging.
Draw a disposition algorithm from “reasonable suspicion” to safe discharge versus admission.

Trauma-Informed Care

Trauma-informed care improves trust, disclosure, examination quality, and follow-up while reducing retraumatization. It is not a substitute for urgent...

0:00 / –:–– AI‑generated audio

The Case

A 34-year-old woman sits rigidly on the edge of the stretcher, clutching her coat around her chest. The smell of antiseptic mixes with cigarette smoke on her clothes, and she flinches when a staff member reaches for the blood-pressure cuff. She says, “I don’t want to talk about it,” while her partner waits just outside the curtain. The examination has not yet begun.

Before You Read

How can routine ED actions unintentionally recreate a patient’s trauma?
What does a safe, noncoercive examination sound like?
How do you preserve autonomy while still treating an emergency?

Why It Matters

Trauma-informed care improves trust, disclosure, examination quality, and follow-up while reducing retraumatization. It is not a substitute for urgent stabilization; it is the manner in which stabilization is delivered.

When to Think of It

Use a trauma-informed approach when a patient appears hypervigilant, dissociative, withdrawn, fearful, angry, unable to tolerate touch or enclosed spaces, or reluctant to disclose sensitive history. It is appropriate for everyone because trauma history is often unknown and may include violence, abuse, war, racism, medical trauma, or prior coercive care.

Sick or Not Sick

The key call is whether immediate physiologic danger overrides the usual pace of consent and privacy. In an unstable patient, perform necessary lifesaving care while explaining what is happening and preserving as much choice and dignity as possible; in a stable patient, slow down, ask permission, and maximize control.

The First Fifteen Minutes

Any patient needing examination or procedure: introduce yourself, explain the next step, ask permission, and offer choices such as positioning, examiner gender when feasible, support person, or a pause; predictability reduces threat responses.
Severe pain or agitation impairing necessary care: ketamine 1 mg/kg IV or 4 mg/kg IM for procedural sedation when indicated, with full monitoring and airway readiness; it provides dissociation when cooperation is impossible. Confirm local sedation protocol and dosing.
Anxiety in a stable patient: do not reflexively medicate; use grounding, paced breathing, a quieter space, and a trusted support person because sedation can impair autonomy and obscure medical assessment.
Acute opioid-related respiratory depression: naloxone 0.04 mg IV, repeat and titrate every 2–3 minutes to adequate ventilation; titration avoids abrupt withdrawal while reversing life-threatening hypoventilation.
Hemorrhagic instability: balanced crystalloid 10 mL/kg IV or blood products according to trauma protocol; explain each action even during rapid resuscitation because communication preserves agency.
Never force disclosure of trauma details that are not medically necessary in the first minutes, and never require the alleged abuser to remain present.

Definitive Care & Disposition

Offer private interviewing, professional interpreters, chaperones, and domestic-violence or sexual-assault advocacy when relevant. Use universal, nonjudgmental language: “Many people experience things that affect health; has anyone made you feel unsafe?” Assess immediate safety, suicidal thoughts, access to weapons, children or dependents at risk, and safe communication methods. Document the patient’s words, consent, refusals, injuries, and resources offered. Disposition should include a medically safe plan, confidential follow-up, crisis resources, shelter or advocacy referral when desired, and mandated reporting when legally required or when a child or dependent adult is at risk.

How This One Kills

The specific failure is interpreting a trauma response—freezing, dissociation, delayed disclosure, inconsistent recall, or refusal of touch—as noncompliance or deception, then abandoning evaluation or forcing an examination that drives the patient away.

The Atypical Presentation

Some patients appear calm, overly agreeable, detached, or eager to leave rather than visibly distressed. Others disclose only after several encounters or after the suspected perpetrator leaves. Trauma memories may be fragmented, and avoidance can look like inconsistency. Preserve privacy, ask behaviorally specific questions without demanding a coherent narrative, and let the patient control pace whenever physiology permits.

Back to Our Patient

Back to the 34-year-old woman: her flinch, rigid posture, reluctance to speak, and partner outside the curtain are cues to use trauma-informed care, not proof of a diagnosis. Because she is currently stable, the team asks permission before touching her, offers a private room and a professional interpreter or support person, and interviews her alone without coercion. They screen for immediate medical danger and safety concerns, explain each examination step, and stop when she asks unless an emergency requires continuation. She receives confidential advocacy and follow-up planning and leaves only with a medically and personally safe disposition.

Patient Presentation to Attending

“This is a 34-year-old woman presenting with chest discomfort and marked distress during routine triage, with a partner waiting outside and no current evidence of physiologic instability. She flinches with touch and initially declines discussion, but she is alert, speaking normally, and has no syncope, focal neurologic deficit, respiratory distress, or obvious traumatic bleeding. I am concerned about possible prior or ongoing interpersonal violence as well as medical causes of her symptoms, so I will first complete a focused assessment privately and with permission. I plan to explain each step, offer choices and a chaperone, check glucose and vital trends, and avoid sedating medication unless safety or a necessary procedure requires it. I will assess immediate safety, document her words accurately, involve advocacy with consent, and arrange a safe follow-up or admission based on medical findings.”

Study Directive

Practice a 30-second trauma-informed introduction and permission statement.
Role-play interviewing a patient privately while a partner attempts to remain in the room.
Review local protocols for intimate-partner violence, sexual assault, mandated reporting, and confidential documentation.
Identify three ED processes that can retraumatize patients and propose a safer alternative for each.
Complete five cases distinguishing trauma responses from delirium, intoxication, hypoglycemia, and neurologic emergencies.

Key Medications

Ketamine for procedural sedation: 1 mg/kg IV, repeat 0.25–0.5 mg/kg IV as needed; 4 mg/kg IM when IV access is unavailable. Verify institutional sedation protocol.
Naloxone: 0.04 mg IV, repeat every 2–3 minutes and escalate as needed to restore ventilation; higher initial doses may be used for apnea.
Midazolam, if required for severe agitation or procedural anxiolysis: 1–2 mg IV, repeat cautiously; dose reductions and monitoring are essential, particularly with opioids or alcohol. Check local protocol.
Avoid benzodiazepines as routine treatment for trauma-related distress; they can worsen disinhibition, respiratory depression, and impaired consent.
Pediatric and pregnancy dosing require age- and condition-specific references; verify with Lexicomp, UpToDate, or institutional protocol.

High-Yield Pearls

A calm or agreeable patient may still be dissociating; absence of visible distress is not evidence of safety.
Ask about immediate safety and safe contact methods before handing a patient written resources.
Consent is an ongoing process: explain, ask, proceed, and re-check.

The Mimics

Delirium or intoxication — fluctuating attention, abnormal vital signs, or toxidrome; attributing medical delirium to trauma delays treatment.
Hypoglycemia — diaphoresis, confusion, agitation, or unusual behavior; missing a glucose check can be immediately fatal.
Psychosis or mania — disorganization, hallucinations, or pressured speech; framing all distress as trauma can miss a primary psychiatric or medical emergency.
Neurologic injury — focal deficit, seizure, or altered consciousness; trauma-informed communication must accompany, not replace, a neurologic evaluation.

Board Question

A stable patient becomes visibly distressed when asked to undress for examination and says, “No one listens to me.” What is the best next response?

A“You need to cooperate so we can rule out serious disease.”
BProceed with the examination without discussion
CExplain the reason for the examination, ask permission, and offer choices about how it is performed
DDischarge the patient because the examination was refused

Reveal answer

Correct: C

Trauma-informed care emphasizes safety, transparency, collaboration, and patient choice while still addressing medical necessity. If the patient remains stable, the clinician should negotiate an acceptable approach rather than coerce or abandon care.
