I1: Cefoxitin 24 h iv with first<br />

1 g dose given in the emergency<br />

department + q 6 h<br />

4 total doses (n=148)<br />

I2: 5 days of iv cefoxitin as<br />

above + q 6 h 20 total doses<br />

Demographics similar.<br />

Overall incidence of infection<br />

76 pts (25.3%) no difference<br />

between groups. Chock<br />

and colon injury predicted<br />

infection but no difference<br />

trauma<br />

Penetrating abdominal<br />

injury. At least one hollow<br />

viscus perforation each.<br />

18–65 years. Computergenerated<br />

randomisation.<br />

Defined SSI. Coverage<br />

of enterococcus. 809 pts<br />

screened. 317 (39%) met<br />

inclusion criteria.<br />

Follow-up 28 days<br />

Iv ampicillin/sulbactam 3 g<br />

(ampicillin 2 g and sulbactam<br />

1 g) as soon as possible, but<br />

not more than 2 h before<br />

operation. After receiving<br />

24 h of unblinded ampicillin/<br />

sulbactam, pts were then<br />

randomised into one of<br />

two groups<br />

I1: 4 more days of drugs iv<br />

I2: 8 pts<br />

High<br />

Number of total transfusions<br />

important risk factor as well<br />

as numbers of organs injured<br />

and presence of hypotension.<br />

The severity of colon injury<br />

was not a risk factor – skin<br />

left open. Low infection rate<br />

overall. Enterococci not a<br />

problem. One day of ab<br />

enough<br />

Overall mortality<br />
