Bleeding
When It’s an ER Emergency

Most cuts in kids look dramatic but stop with pressure. Emergency evaluation matters when bleeding is hard to control or your child seems unwell.

Bring your child to the ER now if:

• Bleeding won’t stop after 10–15 minutes of firm pressure

• A cut is deep, gaping, or you can see fat/tissue underneath

• There’s a nosebleed that won’t stop after proper pressure

• Bleeding follows a head injury or a significant fall

• Your child is very sleepy, pale, weak, dizzy, or hard to wake

• There’s blood in vomit or stool, or stools look black/tarry

Step 1: Try quick first-aid (if it’s safe)

• Apply firm, direct pressure with clean gauze/cloth

• Keep pressure continuous (don’t peek every few seconds)

• If blood soaks through, add more layers — don’t remove the original cloth

• For nosebleeds: sit upright, lean slightly forward, and pinch the soft part of the nose

If bleeding is heavy or you feel faint/weak, skip home care and come in now.

Common bleeding situations — and what to do

Nosebleed

• If it lasts longer than ~15–20 minutes despite proper pressure, or you feel dizzy/weak, get emergency care.

GI bleeding (vomiting blood / blood in stool)

• Vomiting blood, “coffee-ground” vomit, black/tarry stools, or bright red blood in stool can signal serious bleeding — go to the ER.

Bleeding after surgery or a procedure

• If a wound reopens, bleeds steadily, or saturates dressings, contact your surgeon — but if it’s persistent or heavy, ER evaluation may be needed the same day.

Cuts and lacerations

• ER care is appropriate if the cut is deep, won’t stop bleeding, may need stitches, is on the face, or involves numbness/limited movement.

If you’re on blood thinners, don’t “wait it out”

Blood thinners can make bleeding harder to control — and injuries (especially head injuries) carry higher risk.

Go to the ER for:

• Bleeding that’s more than minor, recurring, or hard to stop

• Any significant fall or head injury while on anticoagulants, even if symptoms seem mild

Common blood thinners include:

• Warfarin (Coumadin)

• Apixaban (Eliquis)

• Rivaroxaban (Xarelto)

• Dabigatran (Pradaxa)

• Heparin / Enoxaparin (Lovenox)

“ER or urgent care?”

Choose the ER if bleeding is heavy, persistent, associated with fainting/dizziness, occurs after major injury (especially head injury), or there’s blood in vomit/stool.

Consider urgent care only if:

• bleeding is minor and clearly controlled,

• you feel well,

• and there are no red flags.

If you’re unsure, it’s reasonable to choose ER care — bleeding can be deceptive.

• Wound care and bleeding control (when appropriate)

• On-site imaging (CT, X-ray, ultrasound) to assess internal injury/bleeding risk when clinically needed

• Cardiac care if bleeding is paired with chest symptoms, weakness, or concerning vital signs

• Trauma care support when bleeding follows an injury
