To Study Bacteriological Profile and Antibiotic Sensitivity Pattern in Cases of Neonatal Sepsis

Abstract

Objective: To study the bacteriological profile and sensitivity pattern in cases of Neonatal sepsis at 12 bedded Neonatal Intensive Care Unit (NICU). Methods: This was a prospective study of neonates admitted to our NICU from Jan 2010 to Oct 2011 with diagnosis of neonatal sepsis or those who developed sepsis later during their stay in NICU. All newborns diagnosed as a case of neonatal sepsis, based on clinical features with positive sepsis screen and/or positive blood culture, were included in our study. Blood Culture&Sensitivity was done with conventional non-automated method using Herley's Broth. Results: Out of 55 cases blood culture was positive in 27 (49.09%) cases. Klebsiella Pneumoniae 15 (55.55%) was the most common organism isolated in both early and late onset sepsis showed sensitivity to collistin in 86.6% of cases followed by sensitivity to imipenam-cilastin in 46.67% cases. Only 20% Klebsiella isolates were sensitive to drugs like Ampicillin-sulbactum, Amikacin, Tazobactum, cefpime and for other antibiotics like Meropenam, Piperacillin-tazobactum, Vancomycin it was less than 20%. Other organisms isolated were Staph. aureus, E. Coli, Pseudomonas, Enterobactor, Acinetobactor and candida species. Conclusion: Gram negative organisms are most common cause of early as well as late onset sepsis and there is alarming degree of antibiotic resistance to commonly used antibiotics.
