[Use of preventive intra-operative antibiotic administration in appendectomy. A pharmacokinetic study].

Studies on Cefazedone-kinetics in serum and subcutaneous fat tissue showed an early and lasting tissue concentration high above minimal inhibitation concentrations so that intraoperative single-shot administration of antibiotics are proven to be effective. Due to these pharmacokinetic patterns the results of an earlier prospective trial is confirmed that single-shot antibiotics during surgery are useful to reduce postoperative wound sepsis rate after appendectomy.
