Incidence of catheter-related infections in hospitalized cardiovascular patients

Abstract

Background:Catheter Related Blood stream Infections (CRBSI) are prevalent and a potentially fatal complication pertaining to cardiovascular implant devices. There have been no major studies on bacterial colonization of catheters in cardiovascular patients in Iran.Objectives:To evaluate the incidence of catheter colonization of bacteria in the largest Iranian cardiovascular center.Patients and Methods:March 2011 to 2012, Cauterization procedures performed on 60 patients hospitalized in Rajaie Cardiovascular Medical and Research Center, Tehran, Iran, with arterial or venous catheterization, inserted 48 hours or more, catheter evaluations done by culture methods. Blood cultures were also obtained simultaneously.Results:Forty-four out of 60 catheters (73.3%) were positive with a significant colony count. Of 44 positive cases, 11 patients had positive blood culture. Three most frequently isolated microorganisms were Staph Albus [14 (32%)], Entrococcu [12 (27%)] and Acinetobacter [5 (11%)]. gram-positive cocci were sensitive to Vancomycin and Linezolid and gram-negative bacilli were sensitive to Amikacin, Gentamicin, Tobramycin and Imipenem.Conclusions:The study findings revealed that the catheter infection in our patients had sources other than normal skin flora. These results will assist in determining the possible source of the infections, furthermore, how they are transmitted, moreover aid in controlling and preventing these dangerous in- infections.

Antimicrobial resistance pattern of Gram-positive bacteria during three consecutive years at the nephrology ward of a tertiary referral hospital in Shiraz, Southwest Iran

“…[14] The rate of MRSA reported from other studies in Iran ranges from 40% to 100%. [1518] This ranges between 30% and 40% in different regions of the neighboring country, Saudi Arabia. [19] MRSA frequency largely depends on several factors such as infection control activities and antimicrobial selection pressure.…”

Risk factors and microbial profile of central venous catheter related blood stream infection in medical cardiac care units, National Heart Institute, Egypt

“…Surveillance Methodology: The collection of data for BSIs was performed using active, patient-based, prospective surveillance of the population at risk (i.e., patients who have central line). This means that the infection was sought out during a patient’s stay by screening a variety of data sources, such as microbiology reports, patient records, clinical notes, temperature charts which were recorded in our questionnaire 8 …”

Impedimetric method to monitor biological layer formation on central venous catheters for hemodialysis made of carbothane

“…It is estimated that every year 12-25% of patients die due to complications and infections [14], [15]. Moreover, the number of such cases increases approximately by 1.5% per year [15] and the cost of complications amounts to more than 2.3 billion dollars [16]. The majority of pathogens that cause infections are microorganisms inhabiting the skin, mainly Staphylococcus epidermidis, Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Enterococcus spp., Acinetobacter spp., Klebsiella pneumonae, Enterobacter cloaca [2], [10].…”
