Abstaining Smokers Fare Better After Surgery

11.01.2002


Authors of a study in this week’s issue of THE LANCET conclude that smokers should avoid smoking for around two months before surgery to reduce the risk of cardiovascular or wound-healing complications.



Smokers are at higher risk of cardiopulmonary and wound-related postoperative complications than non-smokers due to the adverse effects of tobacco smoke on the body’s cardiopulmonary function and immune system. Ann Moller and colleagues from Bispebjerg University Hospital, Copenhagen, Denmark, investigated the effect of preoperative smoking intervention on the frequency of postoperative complications in patients undergoing hip and knee replacement.

120 patients who were daily smokers were randomly assigned 6–8 weeks before scheduled surgery to either the control or smoking intervention group. Smoking intervention involved counselling and nicotine replacement therapy, and either smoking cessation or at least 50% smoking reduction. The overall complication rate was 18% in the smoking intervention group and 52% in control patients. The most substantial effects of intervention were seen for wound-related complications (5% compared with 31%), cardiovascular complications (0% compared with 10%), and secondary surgery (4% compared with 15%). The average length of hospital stay was reduced in the smoking intervention group compared with controls (11 days compared with 13 days).


Ann Moller comments: “Smoking is a risk factor for wound infection and cardiopulmonary complications in almost any type of surgery; smokers make up a considerable proportion of the total number of postoperative complications. If preoperative smoking intervention can reduce these complications, the savings in personal suffering and financial expense should be substantial. The results of our study should be consolidated by a health-technology assessment, to test applicability and cost benefit when the intervention is implemented in general practice.”

She concludes: “An effective smoking intervention programme applied 6–8 weeks before surgery more than halved the frequency of postoperative complications, with the greatest effect on wound-related and cardiovascular complications. Although the exact duration of smoking abstinence necessary cannot be concluded from these data, we recommend cessation of smoking for at least 6 weeks on the basis of our results.”

Im Focus: Dresdner scientists print tomorrow’s world

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.

The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".

Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
