Effects of prophylactic antibiotics on wound infection after elective colon and rectal surgery: 1960 to 1980.

ABSTRACT

Wound infection continues to be a common complication of elective colon and rectal surgery. During the period from 1960 to 1980, 42 prospective, controlled prophylactic antibiotic trials were undertaken which addressed this problem. In this report we have analyzed these trials and compared them to all noncontrolled, prospective wound infection surveys and a representative sample of the retrospective surveys of the same period. From this analysis several conclusions have become apparent (1) wound infection remains a common complication for which prophylactic antibiotics are generally effective, (2) the most effective agents are those with activity against anaerobic bacteria, (3) orally administered nonabsorbable antibiotics have little effect on reducing wound infection following these procedures, and (4) the optimal antibiotic regimen is yet to be found. The data do suggest, however, the more preferred regimens currently available as well as those worthy of further investigation.
