In short. Depth, tissue viability, infection and the general state of the patient are assessed together before any decision about closing the wound.
Key points
- Patients often bring a measurement of the gap.
- What changes the plan is which layer has given way and what the edges look like.
- A long superficial split and a short deep one are different problems, and only one is a same-day matter.
An open wound is assessed in a settled order, and each part answers a question that changes what happens next rather than one that is merely recorded. Closing a wound that should have been left open is a worse error than leaving open a wound that could have been closed.
Depth, and what is inside
The first question is which layers have parted. Skin that has separated over intact tissue is a surface problem; a separation that exposes the layer beneath the skin, or anything deeper, is not. It is established by looking inside the gap in good light rather than by measuring it from outside, which is why the assessment is made at the wound rather than over the telephone.
Whether it can hold
The edges are examined for colour, warmth and how readily they bleed. Tissue that is healthy holds a repair; tissue that is dusky, grey or cold, or that does not bleed when touched, does not, and the plan turns towards letting the wound heal from its base. Swelling and tension are read the same way, because a closure under tension tends to come apart again.
Depth is judged inside the gap
Patients often bring a measurement of the gap. What changes the plan is which layer has given way and what the edges look like. A long superficial split and a short deep one are different problems, and only one is a same-day matter.
Infection, excluded first
Redness, heat, hardness, pus, smell and the amount of discharge are recorded with the temperature, the pulse and how unwell the person looks. A wound that has opened is more likely to be infected than one that has not, and infection is dealt with first, because closing over it traps what should drain and tends to fail. A soft bulge that appears when you cough, or a wound that keeps weeping after the edges have met, suggests fluid gathering under the incision; it is felt for by hand as well as looked for.
The patient, and the reasons
Weight, nutrition, blood sugar, smoking, steroid or other medication, and how much you have been doing since discharge are part of the assessment, because they are the reasons a wound fails to hold and the parts a patient can change. Asking about them is not a search for blame; it is how the plan is made realistic.
You should leave with a decision and a timescale: what is being done to the wound now, how the dressing is managed at home, what is being watched for, when it will be reviewed, and who to contact in between. An assessment that ends with reassurance and no interval leaves you judging the next change alone.
Seek emergency care now if
- Bowel or deeper tissue is visible in the gap, 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
What happens at an appointment for a wound that has opened?
The wound is examined by hand and in good light. Depth is established by what is visible inside the gap, the edges are checked for colour and bleeding, infection is looked for and excluded, and any fluid collecting under the scar is felt for. Your temperature, blood sugar control, medicines and how much you have been doing are reviewed at the same time, because those shape what happens next.
Will I need a scan or a blood test for a wound that has opened?
Sometimes, and only where the result changes the plan. A blood test is used when infection or poor nutrition is a real question rather than a routine, and imaging is used when a collection deep to the wound is suspected and its size decides whether it needs releasing. A normal test does not cancel what a clinician can see at the wound.
Does a wound that has opened always need to go back to theatre?
No. Most shallow separations are managed with dressings and review and heal from their base without further surgery. Going back to theatre is considered when the separation is deep, when tissue has lost its blood supply, when something is collecting that needs releasing, or when the wound cannot be kept clean at home. The decision is made after the wound has been examined, not from its appearance.
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.
