[In which operations is antibiotic prevention carried out with only a a single dose? Results of a survey among chief physicians in general surgery in German-speaking Switzerland].

We have been asking 108 surgeons in chief of the German speaking part of Switzerland in what operations they are giving an antibiotic prophylaxis. We wanted to know how far the application of the single-dose concept has been entering every day's practice in Switzerland. Its value has been proven in several prospective, randomized, controlled studies. Out of 84 valid questionnaires we could see that single-dose prophylaxis has not yet come into common use, although it is not only more reasonable but also less expensive than a prolonged course. Fortunately, already 90% of the surgeons are giving an antibiotic prophylaxis in colorectal surgery and 53% in biliary tract surgery. A majority of surgeons do not yet provide antibiotic prophylaxis in gastric surgery nor in appendectomies, where the single-dose prophylaxis is effective as well.
