New data on quitting smoking and surgical risks
Posted on June 20, 2013
New data suggests that one year after quitting smoking, your risks of a smoking-related surgical complication are the same as a non-smoker. The study, published in JAMA Surgery, looked at over 600,000 adult patients between 2008 and 2009, and assessed the effects of current and past smoking (>1 year prior) on postoperative outcomes.
The authors tracked 30-day postoperative mortality, heart attack & stroke, DVT and pulmonary embolism, and respiratory events (pneumonia, unplanned intubation, or ventilator requirement >48 hours).Results: If you were a “current smoker”, your odds of postoperative death were significantly increased, beginning at 10 pack-years of smoking exposure (= 1 pack a day x 10 years), and increasing from there, based on your total exposure.
Smoking cessation at least 1 year before major surgery was found to eliminate the increased risk of postoperative mortality, and also reduced the risks of perioperative heart attack, stroke, DVT and respiratory events.
Editor’s comment: In plastic surgery, we know that smokers have a much higher risk of complication for the surgeries where large flaps of tissue are moved – like facelifts, tummy tucks and breast lifts. The tissues can literally turn black and die…which is a bad thing. While this study didn’t track flap necrosis as a complication, we usually recommend quitting smoking completely for at least 2 months before these kinds of surgeries. But maybe, as this study shows, that time frame isn’t long enough – further research will have to be done to settle that question.
