Culture and Antibiotic Sensitivity of Bacterial pathogens responsible for Post Caesarean Wound Infection in a Tertiary Hospital

Abstract

The objective of this study was to find out the most common bacterial pathogens responsible for post-caesarean wound infection and to determine their antibiotic sensitivity profile. This descriptive cross sectional study was carried out in Obstetrics & Gynaecology Department of Sir Salimullah Medical College & Mitford Hospital from September 2016 to February 2017. 50 admitted patients experienced post-caesarean wound infections and were enrolled in this study. Mean age of study patients was 24.24 years ± 4.39 SD, ranges 17-36 years, 60.0% of them were literate and 40.0% respondents came from lower middle class society. 68.0% respondents were multiparous and 48.0% had regular antenatal check-up. Anemia, hypertension and diabetes mellitus were associated in 54.0%, 18.0% and 6.0% respectively. Rupture of membrane and fetal distress were found in 52.0% and 32.0% cases respectively. In 40.0% cases no growth of organism took place. Growth of Staphylococcus aureus was noticed as predominant organism (28.0%). Pseudomonas, Acinetobacter, E. coli, Klebsiella and Staphylococcus epidermidis were found in 10.0%, 6.0%, 6.0%, 6.0% and 4.0% respectively. S. aureus was sensitive to meropenem (50.0%), imipenem (42.8% ), cefuroxime, doxycycline and amikacin (28.5%). Pseudomonas spp. was sensitive to imipenem (80.0%), meropenem and amikacin (60.0%). Acinetobacter showed 100.0% sensitivity to imipenem followed by piperacillin and meropenem (66.6%). Klebsiella was sensitive to imipenem and amikacin (66.6%). E. coli was sensitive to imipenem (66.6%), meropenem and cefuroxime (33.3%). S. epidermidis was 100.0% sensitive to meropenem followed by doxycycline and imipenem (50%). This study concludes that there is an alarming increasing of wound infections caused by antibiotic-resistant bacteria. Staphylococcus aureus is the commonly responsible organism. Particularly, Pseudomonas and E. coli resistance to third generation cephalosporins are the real threats to control hospital acquired infection.
