Stop smoking before surgery

Studies have shown conclusively that patients who stop smoking before surgery have fewer complications and heal faster than those who continue to smoke.
Smoking cessation before surgery
2012 systematic review demonstrates cessation interventions are effective for surgical patients

The objective of the review was to assess the effect of preoperative smoking intervention on smoking cessation at the time of surgery and 12 months postoperatively and on the incidence of postoperative complications. Eight random controlled trials were included. The analysis demonstrates both intensive and brief intervention significantly increase smoking cessation at the time of surgery. Interventions that begin four to eight weeks before surgery, include weekly counseling, and use nicotine replacement therapy are more likely to have an impact on long-term smoking cessation.
