Prevalence of MRSA among Post Operative Surgical Site Infection of Laparotomy cases in a Tertiary Care Hospital

Dr. V. Kanchana, Dr. S. Radha Kumari

Abstract :

This study was conducted to investigate the prevalence rate of MRSA and their susceptibility pattern among surgical site infection (SSI) in laparotomy cases for 1 year period to provide guidelines for empirical antibiotic therapy and prevention of transmission of MRSA in post operative infections. During the study period , 720 patients underwent Laparotomy surgery , among them SSI was observed in 100 cases . In that about 52% were Gram positive organisms and 46% were Gram negative organisms and 2% were culture negative. Staphylococcus aureus was the predominant causative agent ( 40%) followed by Escherichia coli (17%) . Among 40 Staphylococcus , MRSA was identified in 15 isolates(15%) by disc diffusion method using cefoxitin and rest of them are MSSA (25% ). In that more than 80% of MRSA were resistant to Ampicillin, Gentamycin & Doxycycline & 100% sensitive to Vancomycin, Linezolid & Teicoplanin.
