[Perioperative infection prophylaxis in gastrointestinal surgery].
Antibiotic perioperative prophylaxis is known to reduce postoperative infections and is generally administered as single-dose regimen today. Effective prophylaxis requires plasma- and tissue concentrations above the MIC of the expected bacterial spectrum throughout the whole operation from skin incision to wound closure. In longlasting operations a second dose after 4 hours is recommended. Indications for antibiotic prophylaxis are clean-contaminated or contaminated procedures according to Cruse and in patients with elevated risk of infection. Generally antibiotic prophylaxis is administered intravenously. Chinolons achieving high tissue- and plasmalevels and showing a broad antibacterial spectrum seem appropriate to be used for oral prophylaxis. In a prospective study in 36 patients pharmocokinetics of ofloxacin were measured perioperatively and proper plasma- and tissue concentrations were attained. A following prospective randomized study in 56 patients undergoing colonic or pancreatic resections oral prophylaxis did not show a higher infection rate compared with a standard intravenous prophylaxis. Therefore oral prophylaxis seems to be an attractive option, its effectivity needs to be proven by studies with sufficiently high patient numbers.
