What is the rationale for smoking cessation before surgery?

• A. It delays anesthesia onset.
• B. It has no effect.
• C. It reduces pulmonary complications, improves wound healing, and lowers complication rates.
• D. It improves hair growth.

Answer: (C)

Quitting smoking before surgery improves outcomes by boosting tissue oxygen delivery and reducing airway and wound-healing problems. When a person stops, levels of carbon monoxide fall, so hemoglobin carries oxygen more effectively to tissues, which supports healing and helps the lungs function better after anesthesia. The airway benefits come from improved mucociliary clearance and reduced airway inflammation, which lowers the risk of bronchospasm, pneumonia, and other pulmonary complications in the perioperative period. Nicotine and other smoke toxins also cause vasoconstriction, limiting blood flow to surgical sites; stopping helps restore perfusion and supports faster wound healing. Overall, these changes translate into fewer pulmonary problems, better wound healing, and lower complication rates after surgery. Stopping smoking does not relate to hair growth, and indeed it does affect perioperative risk rather than having no effect.
