Single-dose oral ciprofloxacin plus parenteral metronidazole for perioperative antibiotic prophylaxis in colorectal surgery.

From 1983 until 1990 our standard antibiotic prophylaxis in colorectal surgery has been 80 mg gentamicin plus 500 mg metronidazole, both administered intravenously at the beginning of anesthesia, and then 80 mg gentamicin every 8 h for 3 days. In this time period, 718 patients undergoing elective colorectal surgery by abdominal approach were treated with this prophylactic procedure. The mean wound infection rate was 13.

Penetration of ciprofloxacin and metabolites into human lung, bronchial and pleural tissue after 250 and 500 mg oral ciprofloxacin.

Ciprofloxacin (CIP) and metabolite concentrations in lung tissue, parietal pleura and bronchial tissue were assessed in 43 adult patients who underwent lung surgery. A single oral dose of CIP was given for prophylaxis of bacterial infections. Two to 6 h prior to tissues sampling, 23 patients received 250 mg and 20 subjects 500 mg of the substance.

Transintestinal elimination of ciprofloxacin.

This study identified the routes of elimination of ciprofloxacin in two groups of five subjects each: one of healthy volunteers; the other of patients with severe renal failure having mean creatinine clearance of 12 ml/min (range, 8-16 ml/min). Each subject received one dose of 200 mg ciprofloxacin infused intravenously (IV) over 30 min. In an effort to recover the total drug administered, all urine and feces were collected for 7 days following dosing.
