In short. The findings that cannot wait, the ones that are checked at the next visit, and the reasoning that separates the two in practice.
Key points
- Mark the edge of the swelling on the skin with something soft, write down the time, and repeat after twenty minutes.
- If the swelling has moved past the mark, it is growing and it needs to be dealt with.
- If it has not, and it feels firm rather than tense, it can be raised at a review.
Knowing when to act and when to wait is the whole of this subject, and the reasoning that separates the two is short enough to remember. It rests on two questions rather than on how the area feels.
The two questions
Is the swelling under tension? And is it growing? Everything urgent on this site is urgent because the answer to one of those is yes, and everything that can wait can wait because both answers are no. A soft swelling that is not growing is observed. A tense swelling, or one that is measurably larger than it was, is dealt with now. The size of the bruise does not enter into it, and neither does how uncomfortable the area feels in the absence of those two findings.
Two questions, and one measurement
Mark the edge of the swelling on the skin with something soft, write down the time, and repeat after twenty minutes. If the swelling has moved past the mark, it is growing and it needs to be dealt with. If it has not, and it feels firm rather than tense, it can be raised at a review. That is the entire triage, and it requires nothing more than a mirror and a pen.
What waits for a review
A soft swelling that is not growing. Bruising that is spreading a little and then fading, including bruising that has travelled downwards with gravity. Swelling that is reducing week by week. A firm ridge under the scar that is softening over several weeks. A wound that is dry, with the edges held together and no spreading redness. All of those are the ordinary course, and all of them are worth mentioning at a review rather than acting on now.
What does not wait
A swelling that is tense and growing over hours. Pain that is getting worse instead of settling, and particularly pain that is worsening alongside a swelling that is hardening. Skin over the swelling that has turned dusky, shiny, blistered or cold. Bleeding that is continuing from a wound that was dry. And a wound that is opening. Each of those is a reason to contact the team immediately, and where the skin has changed, to attend the nearest emergency department rather than wait for a reply.
The findings that do not wait
- A swelling that is tense and growing, shown by a mark or a measurement.
- Pain that is worsening, or a wound leaking blood steadily.
- Skin over the swelling that has changed colour, or that has become blistered or cold.
The purpose of the triage is not to make every swelling frightening. It is to make the small number of findings that cannot wait unmistakable, so that everything else can be left to heal without an unnecessary journey and nothing urgent is left until the next appointment.
Frequently asked questions
What can safely wait for a review?
A soft swelling that is not growing, bruising that is fading, swelling that is reducing, a firm ridge under the scar that is softening, and a wound that is dry with the edges held together. Those are the ordinary course of recovery and are raised at a review rather than urgently. The absence of tension and the absence of growth are what make them safe to wait.
What cannot wait?
A swelling that is tense and growing over hours, pain that is worsening rather than settling, skin over the swelling that has turned dusky, shiny, blistered or cold, and bleeding that is continuing from a wound that was dry. Any of those is dealt with now rather than at the next appointment.
How do I judge growth if I am not sure?
Mark the edge of the swelling lightly on the skin, note the time, and look again in twenty minutes. That converts an impression into a comparison. A swelling that has moved past the mark is growing; one that has not is stable. Where you cannot mark it, a photograph with something for scale in the frame and the time recorded does the same job.
Risks & Limitations
- A hematoma is blood collecting where it should not. The findings that matter are tension, growth over hours and a change in the skin over the swelling, not the size of the bruise.
- Blood removed early leaves little trace. Blood left under pressure can compromise the skin over it and can organise into a firm mass that changes the contour permanently.
- A collection is more likely after a rise in blood pressure, after straining or lifting too early, and in a patient who takes medication that affects clotting.
- A wound that has been reopened for evacuation goes through a second period of healing, and the scar can settle less well than it would have done.
- A collection can recur after it has been drained, which is why the provoking factors are reviewed and the restrictions on lifting are part of the treatment.
- No assessment predicts a collection exactly, which is why the warning findings are taught to every patient rather than only to those at higher risk.
When to Seek Care
- A swelling that is tense, tight and larger on one side, growing over hours &mdash — seek emergency care now.
- Pain that is getting worse instead of settling, with a hard swelling &mdash — seek emergency care now.
- Skin over the swelling turning dusky, shiny, blistered or cold &mdash — seek emergency care now.
- Fresh blood leaking steadily through a wound that was dry — contact the team the same day.
- Bruising that keeps spreading well beyond the operated area, or a wound that is coming apart.
- Fever, spreading warmth or discharge around the wound, or feeling generally very unwell.
