Peripheral arterial line - infants: when to get help

Go through these in order and stop at the first one that applies. If you are reading this for someone else, answer for them.

  1. 1

    Is any of this happening now?

    Call 911

    Active bleeding that does not stop with firm pressure, rapid swelling around the site, or a disconnected line requires immediate help.

    Use the bedside call system rather than trying to reconnect or adjust the equipment yourself.

    Call emergency services for severe bleeding or if your infant becomes unresponsive or has serious breathing difficulty.

    Other emergency signs, for anyone
    • Someone who is struggling to breathe, gasping, choking, or cannot get words out
    • Someone who has chest pain, tightness or pressure lasting more than a few minutes
    • Someone who has sudden weakness or drooping on one side of the face or body, slurred speech, or sudden confusion
    • Someone who is unconscious, or cannot be woken
    • Someone who is bleeding heavily and it will not stop with firm pressure
    • Someone who has had a seizure that will not stop, or does not wake up afterwards
    • Someone who has lips or skin that look pale, blue, grey or blotchy
    • Someone who you believe has taken an overdose or swallowed something poisonous
  2. 2

    Is any of this happening?

    Be seen today

    While your infant is in hospital, tell the nurse promptly if you notice new redness, swelling, leaking, bleeding, a loose dressing, or signs that the line has been pulled.

    Ask for an urgent assessment if the hand or foot beyond the line becomes pale, blue, unusually red, cold, swollen, or more painful, or if the fingers or toes move less than before.

    These changes can suggest reduced circulation or pressure on the limb.

    Seek urgent advice for continued bleeding, spreading redness, pus, fever, or a cool or discoloured limb.

  3. 3

    Does any of this apply?

    Book an appointment

    After line removal, routine questions about mild bruising or the dressing can be raised with the healthcare team.
