Pro operative Risks Influencing Wound Infection in Acute Non Perforating Appendicitis

Abstract

                A prospective study was performed to determine the preoperative risk factors of wound infection alter appendectomy that indicated for prophylactic antibiotics in acute non perforating appendicitis.

                Eighty two cases were included in the study. Postoperative wound infections were detected in 7 cases (8.5%). There was no wound infections in all patients that WBC < 15,000 cell/cu.mm. In 21 cases that WBC > 20,000 cell/cu.mm., 10 cases of preoperative prophylactic antibiotics treated patients were discharged without wound infection but there were 4 wound infections in the other 11 patients without antibiotics. The other 2 wound infection cases were older than 40 year old, so the infection rate in the patients that were older than 40 year old was 2 in 9 cases (22%). The other one was short, fat and thick abdominal wall.

                So prophylactic antibiotics in acute non perforating appendicitis those were beneficial in cases of WBC > 20,000 cell/cu.mm. Those who were older than 40 years old, and the obese patients.
