Orthopedic Implant Related Surgeries: Early Surgical Site Infection Bacterial Pathogenecity.
Pak J Med Health Sci Jan ;12(1):564-6.

Aim: To estimate the bacterial pathogen frequencies at surgical site infection among patients with orthopaedic implant surgeries Methods: This descriptive study was carried out at Department of Orthopedics, Qazi Hussain Ahmad Medical Complex, Nowshera and King Abdullah Teaching Hospital, Mansehra from January 2017 to December 2017 and comprised 200 cases. The patient’s demographics, length of hospital stay, provisional diagnosis, procedure performed, culture sent and micro-organism isolated were recorded. All patients with close fractures of long bones for elective surgery, age 5 to 75 years both sexes were included. Patients with soft tissue operations, emergencies and non-implant surgeries were excluded . Results: There were 200 patients Out of which, 1 54 (77%) were male and 46(23%) were females. Among these, infectious micro-organisms were isolated from 1 8 (9%) patients. Klebsiella species were found to be most prevalent 7 cases (38.8%) followed by pseudomonas aeruginosa 5 cases (27. 8%), coagulase negative staphylococci 4 cases (22.2%) and methicillin susceptible S. aureus 2 cases (11 .2%) in the descending order. Twelve (66 .6%) of these patients were treated in the ward for more than 2 weeks and most common isolate in correlation with the prolong stay was pseudomonas aeruginosa. Conclusion: Klebsiella was the most common bacterial agent for causing early surgical site infections. The frequency of various bacterial infections at SSI among patients admitted for closed fracture procedure was upto 9%. Patients having a prolonged hospital stay were more prone towards pseudomonas aeruginosa infection.
