Burns, Cuts, and Head Injuries — A Decision Map for "Go Now or Wait and Watch"

Lead

Children's injuries do not always match their apparent severity. A cut with considerable bleeding may require no stitches, while a head injury with no visible wound may need careful observation. Making a good call in a moment of panic is easier when the relevant criteria are already in mind. This article covers three of the most common injury types — burns, lacerations, and head trauma — with specific decision criteria for each.

Burns: What the Evidence Supports

The best-supported initial intervention for a burn is cooling with running water. Japanese burn care guidelines (3rd revised edition) recommend starting water cooling as soon as possible after injury and continuing for 15–20 minutes [6]. Cooling begun even within three hours of injury has been shown to reduce burn depth progression, so there is value in starting promptly even if the injury is not brand new.

The water should be cool but not ice-cold. Cooling with ice water risks hypothermia, particularly in young children, and is not recommended. Folk remedies — butter, toothpaste, soy sauce applied to the burn — should not be used; they increase infection risk and interfere with evaluation.

Criteria for seeking care (based on American Burn Association guidelines [2]):

Blistering has formed (indicates or )
The burn involves the face, hands, feet, genitals, or a joint (regardless of area)
There is concern that smoke or hot gases were inhaled
In young children, burn area estimates should apply more conservative thresholds, since body surface area is proportionally smaller

A rough field estimate: the child's palm represents approximately 1% of their body surface area.

Lacerations: Stitches or No Stitches?

The question of whether a laceration requires suturing turns less on the amount of bleeding than on wound depth. A superficial skin laceration — even one that bleeds freely — may close adequately with five to ten minutes of firm, clean pressure, without requiring emergency evaluation [5].

Criteria that suggest suturing is likely needed:

The wound is deep and the edges gape open
Bleeding continues despite sustained pressure (especially pulsatile bleeding suggesting arterial involvement)
The laceration is on the face or over a joint where function or cosmesis is at stake

Facial lacerations often warrant plastic surgical management for cosmetic outcome. Even when suturing is not necessary, medical-grade closure strips (Steri-Strips) or wound-closure tape can be applied in a clinical setting to approximate the wound edges — this is worth an outpatient evaluation when in doubt.

Head Trauma: Using the PECARN Decision Rule

The (PECARN) published a validated clinical decision rule in 2009, based on a prospective cohort of more than 42,000 children, for stratifying the risk of clinically important [1]. It classifies children into high-, intermediate-, and low-risk groups.

Seek emergency care immediately (high risk):

Any loss of consciousness, even momentary
Altered mental status or neurological symptoms (lethargy, unresponsiveness)
Signs of skull fracture (palpable step deformity, boggy swelling over bone)
Vomiting two or more times
In children aged 2 or older: severe mechanism of injury (fall from significant height, high-speed impact)

Consider evaluation (intermediate risk):

A single vomiting episode
In children under 2: fall from a height greater than 90 cm [1]
Persistent severe headache

Observation at home is usually appropriate (low risk):

Normal consciousness and conversation
Behaving normally after the injury
None of the above findings

PECARN sensitivity for clinically important intracranial injury is reported at 98–100% [1]. "Low risk by PECARN" is not a reason to stop watching — for 24 hours following any significant head impact, changes in behavior, repeated vomiting, or increasing drowsiness warrant a reassessment.

A note on CT scans: CT carries radiation exposure. One of PECARN's explicit design goals was reducing unnecessary CT use while reliably identifying serious injuries. When there is genuine uncertainty, consultation with a pediatric emergency physician is the right step rather than self-administering a CT decision.

Three Practical Framings

Writing "cool with running water for 15–20 minutes" on the refrigerator or inside the first-aid kit makes it retrievable in a stressful moment when memory fails.
After a head injury, allocating the two to four hours following impact to observation — noting whether the child seems normal, whether vomiting occurs, whether eye tracking looks right — makes the "go or stay" decision much easier.
For a laceration where stitches are uncertain, applying firm pressure with a clean cloth while going to urgent care or an emergency room is the reliably correct course.

Summary

For pediatric injuries, the most useful assessment criteria are not visual drama — blood volume, size of the mark — but specific clinical indicators: burn location and blistering, wound depth and edge approximation, and the PECARN neurological findings for head trauma. "Something feels off" is a valid reason to seek evaluation. The purpose of having criteria in advance is not to make parents into clinicians, but to reduce the number of decisions being made purely on panic.
