Prevalence of Antibiotic Resistant Pathogens in Post-Orthopedic Implant Site

Abstract

Objective: To assess the frequency of infective organisms and their changing antibiotic sensitivity trends in surgical site infection after orthopedic implant surgeries.

Study Design: Cross sectional study.

Place and Duration of Study: This study was conducted at the Department of Orthopedic Surgery, Divisional HQ Hospital Mirpur AJK from January 2018 to December 2018.

Materials and Methods: Ninety six patients of both genders and age between 16-80 years with surgical site infection after elective surgeries were included. Patients’ demographics were recorded. Type of most common pathogen and its sensitivity pattern were recorded.

Results: The mean age of patients was 45.93±10.58years. There were 51 (53.1%) males and 45 (46.9%) females. There was Staphylococcus aureus was found in 33 (33.96%) cases, MRSA was found in 18 (18.75%) cases, E. coli was found in 15 (15.63%) cases. Ceftriaxone was sensitive in 88 (91.7%) cultures, Ampicillin was sensitive in 62 (64.6%) cultures, and Metronidazole was sensitive in 58 (61.4%) cultures.

Conclusion: The frequency of Staphylococcus aureus was found to be most common pathogen in SSI and ceftriaxone was most sensitive antibiotic for SSI management.
