Introduction: Surgical Site Infections (SSIs), previously called post operative wound infections, result from bacterial contamination during or after a surgical procedure.Surgical site infections are the third most common hospital associated infection, accounting for 14-16 per cent of all infections in hospitalized patients

Aims and objectives:

  1. To establish the pattern of wound infection in terms of aerobic organisms after contaminated and infected surgical procedures.
  2. To study the incidence of septic complications.

 3.Pattern of antibiotic sensitivity for different organism in the present era

Materials and methods:50 patients having emergency or elective traumatic or non- traumatic abdominal operations who fulfil the criteria of infected and contaminated wounds are included in the study. Patients to be studied were selected in random basisâ

A-Per operative-Swab culture, Peritoneal fluid culture in syringe, Tissue, Pus

B-Post operative- On 3rd/4thpost-operative day wound exudate{if present} Wound Swabs(2 in nos.)/Pus in syringe/Tissue

Sample are processed for Aerobic culture and antibiotic sensitivity.



The incidence of wound infection is 31.57% in contaminated surgical procedures and 29.03% in infected surgical procedure. Operation in emergency set up results in an increased risk of wound infection. Patients with positive intra operative bacteriology runs a higher risk of developing wound infection. The commonest organism isolated from intra operative swab cultures were E.coli followed by klebsiella in both infected and contaminated procedures. Presence of polymicrobial flora in intraoperative swab culture is associated with higher rate of wound infection.Staph Aureus was found to sensitive to vancomycin,Tiecoplanin, Linezolid whereas Streptococcus was sensitive to Levoflox, Ampicillin and Vancomycin. E.coli ,Klebsiella were found to hav sensitivity towards Amikacin,Levofloxacin
