To determine the incidence, risk factors and common bacterial pathogens in surgical site infection (SSI) following C–section in a tertiary care centre. A hospital based prospective study conducted for a period of 6 months. 62 women were studied whose C–section was complicated by SSI within 5 days postoperatively; Risk factors for SSI were identified and microbiological pattern was studied. During this study period post caesarian SSI incidence was 0.34%. In this study post C–section SSI found as high as 43.55%, in lower socio economic status; Among all patients, un–booked were 62.90%, Referred patients were as high as 67.74%. SSI developed in 69.35% patients without preoperative antibiotic prophylaxis. C–section done in PROM in 64.50% and as an elective emergency 79.03%, blood transfusion needed in 59.68% and type of incision being transverse(Pfannenstiel) in 88.71%. subcutaneous suture technique used in 75.81% and secondary healing occurred in 67.74%. Most common organism grown was CoNS(coagulase negative staphylococcus) 29.03% in SSI.
