Smoking Cessation Before Surgery: Why It Matters and When to Stop

Smoking triggers several mechanisms that impair wound healing, tissue oxygenation and immune response. That is why stopping before a planned operation is one of the strongest contributions a patient can personally make to surgical safety.

How does smoking affect surgery?

• Wound healing may be delayed and the risk of wound dehiscence rises
• Post-operative lung complications (atelectasis, pneumonia) become more frequent
• Reduced tissue oxygenation increases the risk of infection
• Vascular spasm and clot risk rise; cardiovascular events may occur more often
• Airway reactivity and cough during anaesthesia can increase

How far in advance should you stop?

The 2020 WHO patient guidance emphasises that stopping at least 4 weeks before surgery meaningfully reduces the complication rate. International ERAS (Enhanced Recovery After Surgery) protocols point in the same direction. Even short-term cessation (48–72 hours) can lower carbon monoxide levels and improve tissue oxygenation — so every day is a gain.

How is nicotine replacement planned?

Nicotine patches, gum or prescription medications can make cessation easier. These treatments are started after a medical review. In cardiovascular disease, pregnancy or other specific conditions the choice may differ. Support can also be obtained through primary care or dedicated smoking-cessation clinics.

How the process works in Antalya

• Smoking history is asked in detail during pre-operative assessment
• A target quit date is agreed together
• Referral to primary care or a smoking-cessation clinic is arranged if needed
• Practical suggestions are offered to maintain cessation after surgery
