Large number of vascular catheters (central line, arterial line, peripheral venous catheters) are inserted into patients which serve as a source of nosocomial infections, resulting in septicaemia associated with substantial mortality and morbidity. Aim is to study the risk factors, bacteriological profile and antimicrobial susceptibility pattern of bacterial isolates from vascular catheter segments and tips. Total 69 vascular tips and 69 blood culture from the same patients were analyzed for culture and sensitivity by standard microbiological procedure and the associated risk factors were identified. Out of 69 vascular tips, 31 (44.92 %) showed significant growth. Forty two percent were gram negative bacilli, 51.61% gram positive cocci and 6.45 % showed growth of Candida species. Staphylococcus aureus and Klebsiella pneumoniae were the most frequently isolated organisms. Only 5 blood culture samples were positive. Most effective antibiotic for Staphylococcus aureus was Cotrimoxazole and Gentamicin (7/12, 58.33%).Most susceptible antibiotic for Enterobacterales was Tigecycline(7/9,77.77%). Staphylococcus aureus remains the most common organism isolated from vascular tip. Prolonged ICU (intensive care units) stay and longer duration of catheterization are most common risk factors leading to increased colonisation and morbidity in cases of vascular catheter infections. Regular surveillance of vascular catheter associated infections is required for better patient care outcomes. Strict adherence to infection control protocols need to be there while insertion and removal of catheter.
