In short. How patients are assessed before reconstructive surgery: health screening, anesthesia evaluation, smoking and medicines, and what a hospital setting adds to safety.
Key points
- Smoking is the single most correctable risk in reconstructive surgery: nicotine constricts the small vessels that keep flaps, grafts, and delicate skin covers alive, and reconstruction in an active smoker fails measurably more often.
- Surgeons will ask you to stop well before and after surgery, and some reconstructions should simply not be offered to someone who cannot.
- Medicines that affect clotting are reviewed individually and adjusted with the prescribing doctor — never stop them on your own.
Reconstructive surgery is elective surgery: nobody needs it today, which means there is always time to do it safely. Pre-operative assessment is the unglamorous work that decides who can proceed, what must be optimized first, and where the operation should happen. Done properly, it prevents most preventable disasters.
Health screening
Assessment starts with your medical history: heart and lung conditions, diabetes, blood pressure, previous anesthesia problems, bleeding history, and healing problems. Blood tests, an ECG, and imaging are added as age and condition dictate. Uncontrolled conditions are reasons to postpone and optimize, not to cancel forever — controlled diabetes and treated hypertension change the risk genuinely.
Smoking, medicines, and supplements
The honest rules
Smoking is the single most correctable risk in reconstructive surgery: nicotine constricts the small vessels that keep flaps, grafts, and delicate skin covers alive, and reconstruction in an active smoker fails measurably more often. Surgeons will ask you to stop well before and after surgery, and some reconstructions should simply not be offered to someone who cannot. Medicines that affect clotting are reviewed individually and adjusted with the prescribing doctor — never stop them on your own. Many supplements affect bleeding too; declare everything, including the ones that seem harmless.
Anesthesia assessment
Most reconstructive operations use general anesthesia, assessed beforehand by an anesthesiologist who reviews airway, heart, lungs, medicines, and previous anesthetic experiences. In a tertiary hospital this assessment is a formal process with the full monitoring, blood bank, and intensive care infrastructure behind it — relevant for long operations such as free-flap breast reconstruction or rib cartilage harvest.
Why the setting matters
The same operation carries different real-world risk in different buildings. A hospital setting means resuscitation capability, intensive care, and specialist colleagues are immediately present if bleeding, an anesthetic problem, or flap trouble occurs in the hours after surgery — the window when most serious complications declare themselves. Ask where your operation will be performed and what backup exists.
Your part
Answer health questions completely, including the embarrassing parts; follow fasting instructions exactly; arrange help at home for the first days; and report any new illness before surgery day — operating through a fresh cold is a bad trade.
Risk, stated plainly
No assessment makes surgery risk-free; it makes risk visible and manageable. Even well-prepared patients occasionally have complications. The point of assessment is that your individual risk is known, minimized, and honestly discussed before you consent.
Tell your team before surgery if
- You smoke or use nicotine in any form, or have recently stopped — the plan may need to change, not just the lecture.
- You take any blood-thinning medicine or daily supplement, however routine it seems.
- You develop a cold, fever, skin infection near the surgical site, or any new symptom in the days before the operation.
Frequently asked questions
Why does smoking matter so much before reconstruction?
Nicotine constricts the small vessels that keep flaps, grafts, and delicate skin covers alive, and reconstruction in an active smoker fails measurably more often. Surgeons ask patients to stop well before and after surgery, and some reconstructions should not be offered to someone who cannot.
Should I stop my blood-thinning medicines before surgery?
Not on your own. Medicines that affect clotting are reviewed individually and adjusted together with the prescribing doctor, and many supplements affect bleeding too. Declare everything you take, including the products that seem harmless.
Why does the hospital setting matter for safety?
The same operation carries different real-world risk in different buildings. In a hospital, resuscitation capability, intensive care, and specialist colleagues are immediately present if bleeding, an anesthetic problem, or flap trouble occurs in the hours after surgery — the window when most serious complications declare themselves.
Risks & Limitations
- Reconstruction is usually staged — more than one operation is normal, and the plan may change as healing progresses.
- Donor-site scarring and discomfort, including after rib cartilage harvest.
- Partial or complete failure of a flap or graft, which may require further surgery.
- Scars are permanent. They mature and fade but never disappear.
- Asymmetry and the inherent limits of matching a normal side.
- Altered sensation, numbness or weakness in the operated area.
- Contracture, which may need release procedures later.
- Final assessment is made at 6–12 months, and longer in growing children.
When to Seek Care
- A flap or graft that turns dark, cold, black or stops bleeding when pricked.
- Fever above 38 °C, or spreading redness, warmth or discharge around a wound.
- New or worsening pain, swelling or fluid leakage from the operative site.
- Bleeding that does not stop with gentle pressure.
- Any change in a reconstructed area that concerns you, however minor.
