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: Gamma-ray flashes from plasma filaments

Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.

Stable joint cartilage can be produced from adult stem cells originating from bone marrow. This is made possible by inducing specific molecular processes occurring during embryonic cartilage formation, as researchers from the University and University Hospital of Basel report in the scientific journal PNAS.

Certain mesenchymal stem/stromal cells from the bone marrow of adults are considered extremely promising for skeletal tissue regeneration. These adult stem...
