[Operating site infection in the orthopedic surgery department at the hospital of Sikasso].

Introduction: The objective of this study was to determine the incidence of the operating site infection, precise the etiologies and identify the risk factors.

Patients And Method: This was a prospective study conducted at the department of orthopedics and traumatology at the hospital of Sikasso. The study was conducted from January 2016 to December 2018. The infection criteria were those of CDC from Atlanta.

Result: This study was conducted on 140 patients including 105 men and 35 women with an average age of 40, 1 years old (3 and 88 years old). We have made 150 interventions including 131 osteosynthesis, 14 arthroplasties and 5 corrective osteotomies. The global incidence of the operating site infection was of 19, 3% with a 13, 4% incidence in surgery class I, 21, 4% in the class II, 26, 5% in the class III and 50% in the class IV. . It was superficial in 18 cases (62, 1%) and deep in 11 cases (37, 9%). The average post-surgery hospitalization duration was 13 days (5 and 70 days in extreme cases). The isolated germs were in 6 cases (37,5 %), in 3 cases (18,7 %), 3 cases (18,7%), (12,5 %,), in 1 case (6,3% (6,3%). They were 100% sensible to imipramine. 90% of the cases were resisting to ampicillin and penicillin G.

Conclusion: The incidence of the ISO in our department was high. The risk factors of Operating Sites Infections were: hospitalization duration beyond 2 days, ASA Score over 2 days long, the surgical intervention class and the operation duration higher than 3 hours.
