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: High-pressure scientists in Bayreuth discover promising material for information technology

Researchers at the University of Bayreuth have discovered an unusual material: When cooled down to two degrees Celsius, its crystal structure and electronic properties change abruptly and significantly. In this new state, the distances between iron atoms can be tailored with the help of light beams. This opens up intriguing possibilities for application in the field of information technology. The scientists have presented their discovery in the journal "Angewandte Chemie - International Edition". The new findings are the result of close cooperation with partnering facilities in Augsburg, Dresden, Hamburg, and Moscow.

The material is an unusual form of iron oxide with the formula Fe₅O₆. The researchers produced it at a pressure of 15 gigapascals in a high-pressure laboratory...

Im Focus: A step towards controlling spin-dependent petahertz electronics by material defects

The operational speed of semiconductors in various electronic and optoelectronic devices is limited to several gigahertz (a billion oscillations per second). This constrains the upper limit of the operational speed of computing. Now researchers from the Max Planck Institute for the Structure and Dynamics of Matter in Hamburg, Germany, and the Indian Institute of Technology in Bombay have explained how these processes can be sped up through the use of light waves and defected solid materials.

Light waves perform several hundred trillion oscillations per second. Hence, it is natural to envision employing light oscillations to drive the electronic...

Im Focus: Freiburg researcher investigate the origins of surface texture

Most natural and artificial surfaces are rough: metals and even glasses that appear smooth to the naked eye can look like jagged mountain ranges under the microscope. There is currently no uniform theory about the origin of this roughness despite it being observed on all scales, from the atomic to the tectonic. Scientists suspect that the rough surface is formed by irreversible plastic deformation that occurs in many processes of mechanical machining of components such as milling.

Prof. Dr. Lars Pastewka from the Simulation group at the Department of Microsystems Engineering at the University of Freiburg and his team have simulated such...
