Retrospective Study of Surgical Site Infection in an Urban Centre of Eastern India
Background: In compromised operation room and ward environment does extended prophylactic antibiotic for beyond 24 h
do better for preventing surgical site infection (SSI)?
Materials and Methods: In this retrospective transverse cross-sectional study 899 (major = 699 and minor = 230) post-operated
patients are investigated for the incidence of infection. The patient population is distributed in trauma, arthroplasties, and others
as 508, 106, and 285, respectively.
Results: In major procedures infection developed as superficial incisional, deep incisional, and deep organ space are 4.33%,
1.20%, and 1.05%, respectively, and average total being 6.93%. In minor procedure, the values are 2.17%, 0.43%, and 2.70%.
The incidence of SSI in arthroplasties was 11 (10.38%). Minimum period for identification for SSI 6 days in 11 cases and as late
as 53 days in 1 case. Organism prevalence was Staphylococcus aureus 51.92% (MRSA = 51.85%), Staphylococcus epidermidis
in 8, Streptococcus in 12, Escherichia coli in 2, Klebsiala in 1, and Pseudomonas in 2 cases. Combining debridement and
suitable antibiotics SSIs controlled in 27 cases and failed in 25 cases.
Conclusion: Prolonged prophylactic antibiotic use cannot reduce the incidence of SSI. It makes delay in identification of SSI
leading to difficulties in controlling it. Prophylactic antibiotic is never an alternative for the antiseptic surgical protocol.
