Prevalence of surgical site infection in two methods of patients preoperative preparation

الملخص EN

Surgical site infections are the second most common nosocomial infections.

As surgical site infection is the cause of significant mortality and morbidity in patients, recognition of risk factors and routs of decreasing their incidence is of considerable value.

In this study, 1383 orthopaedic operations, which were conducted from 1999 to 2000 in Shariati Hospital, were reviewed.

There were two groups of patients: In the first group, the patients were shaved on the day before operation and in operating room, after application of betadine 7.5%, the patients were painted with betadine 10% before the operation.

In the second group, shaving and painting (without scrub) was done in the operating room just before surgery.

The prevalence of surgical site infection in these two groups was recorded.

Statistical analysis with T-test and Chi-square methods revealed that although overall surgical site infection prevalence in two groups was the same, but the prevalence of deep infection in group twp was significantly lower than that of group 1 (P < 0.01).

This difference leads to a decrease in therapeutic cost of approximately 560000000 Riyals each year in this country.
