Study of Bacteriological Profile of Post Operative Wound Infections In Obstetrics And Gynaecological Surgeries In A Tertiary Care Hospital
Keywords:
Surgical site infection, antibiotic resistance, MRSAAbstract
Background & objectives: Surgical site infections (SSI) are third most commonly reported nosocomial infections. For any given type of operation, development of a wound infection approximately doubles the cost of hospitalization. So the present study conducted to isolate different organisms from post-operative wound infections from Obstetrics and Gynaecology surgeries, to determine antibiotic sensitivity pattern of these isolates and to determine the rate of SSI. Methods: All the pus samples of clinically suspected SSI cases were immediately processed by standard bacteriological techniques. Antibiotic susceptibility testing was performed. Results: The incidence of SSI in our set up was 1.64 %.The most common organism isolated from SSI cases was staphylococcus aureus (41.42%). 31.03% MRSA were isolated from SSI cases. All the MRSA were sensitive to vancomycin and Linezolid. Gram negative bacilli showed maximum sensitivity towards piperacillin-tazobactam, imepenem & polymyxin B.The production of ESβL among Gram negative bacilli varies from 25% to 33% and Ampc β lactamase production varies from 12% to 25%. Interpretation & conclusion: Guidelines and protocols for basic infection control practices such as hand washing, written protocols of perioperative, intraoperative and post operative infection control practices should be widely available and adhered to.
