In short. The findings at an incision that must not wait for a scheduled appointment, each with the specific action and the timeframe that belongs to it.
Key points
- Redness that is spreading is judged by comparison, and a line drawn around it with the time written beside it turns an impression into a measurement.
- It is the single most useful thing a patient can bring to a same-day assessment, and it takes no more than a pen.
- Do the same with the discharge: note how many dressings a day.
A red flag is not the most painful thing that can happen after an operation. It is a finding that is moving under its own momentum, at a point where acting today is easier than acting next week. That is why the list is short, and why each item carries its own timeframe rather than a general instruction to seek help.
Emergency care now
Bowel or deeper tissue visible in the gap where the incision has parted. Bleeding that does not stop with firm pressure held on the wound. Fever with chills or shivering. Redness spreading away from the incision with skin that is hot, hard and tender. Chest pain or difficulty breathing. Feeling faint, or being unable to keep fluids down. Cover the wound, take the discharge summary, and go to the nearest emergency department rather than telephoning first.
Contact the team the same day
An incision that has parted but looks shallow. Discharge that is increasing rather than drying, or that has turned yellow, creamy or foul-smelling. Pain that is far worse than the operation would explain, or that has returned after several comfortable days. A soft bulge under the scar that appears when you cough or stand. A gap that is widening. Each is a telephone call rather than an attendance, and none should wait for a scheduled appointment.
Mark the edge and note the hour
Redness that is spreading is judged by comparison, and a line drawn around it with the time written beside it turns an impression into a measurement. It is the single most useful thing a patient can bring to a same-day assessment, and it takes no more than a pen. Do the same with the discharge: note how many dressings a day.
Why the timeframe is not severity
A patient can be in considerable pain and belong in the telephone group, and feel almost nothing and belong in the emergency group. Fever with chills and a spreading redness can be quiet at the start, while a wound that has opened a little can be the most uncomfortable thing in the room. The timeframe is set by what the finding might be, not by how much it hurts.
If you are unsure
Take the higher one. Being seen and told that nothing is wrong costs an evening, and the other error costs the interval in which a treatable problem becomes a settled one. If the team cannot be reached and the hours are passing, attend rather than wait. Say what operation you had, on which date, what you are seeing now, and which way it is moving, and say the thing you are most worried about first.
Seek emergency care now if
- Bowel or deeper tissue is visible where the incision has parted, or bleeding will not stop with firm pressure.
- There is fever with chills or shivering, or redness spreading with heat and hardness.
- There is chest pain, difficulty breathing, or the person feels faint or cannot keep fluids down.
Frequently asked questions
Which findings at an incision mean I should not wait for my review appointment?
An incision that has parted, discharge that is increasing rather than drying, pus or a bad smell, pain far worse than the operation would explain, and a soft bulge under the scar that appears when you cough or stand. Each of those is moving under its own momentum, and each is easier to manage on the day it appears than a week later. Telephone the surgical team rather than waiting.
How quickly should I act on a red flag?
The timeframe belongs to the finding rather than to how worried you feel. A separation with deeper tissue showing, bleeding that will not stop, fever with chills or shivering, spreading redness with heat and hardness, chest pain or difficulty breathing, and feeling faint or unable to keep fluids down are all emergency care now. The rest of the list is a telephone call the same day.
What if I telephone the team and cannot reach anyone?
Attend rather than wait for a call back, if the finding is in the same-day group and the hours are passing. A wound that has parted, discharge that is increasing or pain that is worsening do not stop for a telephone queue. If you are unsure whether the finding belongs to the emergency group, treat it as though it does, and let the team move it down rather than up.
Risks & Limitations
- Every incision carries a risk of separating, and no operation can make that risk disappear.
- A wound that has opened heals with a scar, and scarring is permanent. It matures over 6 to 12 months but does not disappear.
- Healing after a separation takes longer than the original recovery, and the interval varies between people.
- Most separations are managed with dressings rather than further surgery, and some are not. A revision is another operation with its own recovery.
- The final appearance is judged months after the wound has closed, not at the first dressing change.
When to Seek Care
- Difficulty breathing or chest pain, or bleeding from the wound that does not stop with firm pressure: emergency care now.
- Fever with chills or shivering, or redness spreading with heat and hardness around the incision: emergency care now.
- An incision that has parted with bowel or deeper tissue visible in the gap, or feeling faint or unable to keep fluids down: emergency care now.
- An incision that has parted but looks shallow, discharge that is increasing, pus or a bad smell, or pain far worse than expected: contact the surgical team the same day.
