Pre-emptive antibiotic treatment vs 'standard' treatment in patients with elevated serum procalcitonin levels after elective colorectal surgery: a prospective randomised pilot study.
Procalcitonin (PCT) is regarded as a specific indicator of bacterial infection. Infectious complications in patients after colorectal surgery are a common cause of morbidity and mortality. The aim of this study was to investigate (a) whether PCT could serve as a negative predictive marker for postoperative complications and (b) whether, in patients with elevated PCT levels, a pre-emptive treatment with the third-generation cephalosporin ceftriaxone is superior to an antibiotic treatment starting later on the appearance of clinical signs and symptoms of infection.. By screening 250 patients with colorectal surgery, we identified 20 patients with PCT serum levels more than 1.5 ng/ml on at least 2 of the first 3 postoperative days. The remaining 230 patients were followed-up for the occurrence of infectious complications. The 20 patients with elevated PCT were included in a prospective randomised pilot study comparing pre-emptive antibiotic treatment with ceftriaxone vs standard treatment.. The negative predictive value of PCT for systemic infectious complications was 98.3%. In patients receiving pre-emptive antibiotic treatment (ceftriaxone), both the incidence and the severity of postoperative systemic infections were significantly lower compared to those in a control group (Pearson's chi(2) test; p=0.001 and p=0.007, respectively). Major differences were also observed with respect to duration of antibiotic treatment and length of hospital stay.. PCT is an early marker for systemic infectious complications after colorectal surgery with a high negative predictive value. A significant reduction in the rate of postoperative infections in patients with elevated PCT serum concentrations was achieved by means of pre-emptive antibiotic treatment.

Single dose ceftriaxone as prophylaxis for sepsis in colorectal surgery.
During the period May 1986 to July 1989, a prospective, double blind, randomized trial of antibiotic prophylaxis in colorectal surgery was undertaken at the Royal Brisbane Hospital. Three hundred and thirty patients were considered eligible for the trial. Three regimens were compared: a combination of 2 g ceftriaxone and 1 g metronidazole; a single dose of 2 g ceftriaxone; or 1 g cefazolin and 1 g metronidazole, as antibacterial prophylaxis in colorectal surgery. Fifty patients were excluded from analysis. The overall incidence of wound sepsis was 7.9% (22 patients). There was no statistical difference in the incidence of wound infections between the three groups. The presence of drains and the non-performance of a bowel anastomosis at the time of surgery predisposed patients to wound infection. Staphylococcus aureus or Staphylococcus epidermidis were the cause of wound infection in 16 cases. Patients in the cefazolin and metronidazole group had a significantly higher number of postoperative urinary tract and respiratory tract infections than the other two groups combined (P less than 0.01). There did not appear to be any change in sensitivity patterns to ceftriaxone during the 3 year trial. During the 3 year period of the study, ceftriaxone was found to be a safe and effective drug in antibacterial prophylaxis in colorectal surgery.

Short-term antibiotic prophylaxis in elective colorectal surgery.
In the last 2 years, 50 patients who underwent elective colorectal surgery were prospectively studied about antibiotic prophylaxis. Two groups of 25 patients each were randomly selected. Both received: (a) a colic preparation: hypactic drugs and two enemas during the day before surgery and (b) metronidazole 0.5 g plus neomycin 1 g per 8 h orally for 1 day before surgery. Every group also received: group A, metronidazole 0.5 g plus amikacin 500 mg i.v. 2 h before surgery and the same doses per 8 or 12 h, respectively, for 2 days postoperatively; group B, ornidazole 1 g by intravenous infusion plus ceftriaxone 2 g i.v. 2 h before surgery and the same doses of the drugs per 24 h for 2 days postoperatively. Wound infection occurred in 1 case of group A versus 2 cases of group B (p greater than 0.25). Ornidazole plus ceftriaxone prophylactic antibiotic therapy is therefore as effective as a classic therapy (metronidazole plus amikacin) and constitutes an alternative choice for patients undergoing elective colorectal surgery, because the simple manner of its administration (once per 24 h) is resulting in cost saving due to gained nursing time.

[Preliminary results of a bacteriologic and immunologic study in patients subjected to colorectal surgery].
This study examines patients undergoing colorectal surgery for carcinoma, bacteriological data in faecal and systemic immunological data; these patients before surgery received short-term chemoprophylaxis with ceftriaxone (2 g e.v.) and thymopentina (1 phial/day for 15 days) and after surgery thymopentina (1 phial for three time a week). With these data the authors try to create immunomodulation and antibiotic chemoprophylaxis protocol for the reduction of the septic complications due to intestinal bacterial flora and immunological defence reduction.
