Cefotaxime-heparin lock prophylaxis against hemodialysis catheter-related sepsis among Staphylococcus aureus nasal carriers.

Staphylococcus aureus nasal carriers undergoing hemodialysis (HD) through tunneled cuffed catheters (TCCs) form a high-risk group for the development of catheter-related bloodstream infections (CRBSI) and ensuing morbidity. The efficacy of antibiotic-locks on the outcomes of TCCs among S. aureus nasal carriers has not been studied earlier.

Vascular access related infections in hemodialysis patients.

Hemodialysis (HD) patients are at considerably high risk for vascular access-related blood stream infections (VRBSI) that result in serious complications. Such severe infections are a great deal more frequent with central venous catheters (CVCs) and polytetrafluoroethylene (PTFE) grafts than with arteriovenous fistula (AVF). Nonetheless, the CVCs, though having "undesirable" side effects, remain "unavoidable" for the patients requiring instant dialysis access, as a consequence of the unpredictable course of chronic renal disease.

Vascular access related septicemia in hemodialysis: a focus on bacterial flora and antibiotic access salvage.

A good vascular access is the lifeline of patients on long-term hemodialysis (HD) and anteriovenous fistula is considered the ideal access. Vascular access related septicemia (VARS) is the second most common cause of mortality among HD patients. Such infections could also lead to loss of vascular access unless specific measures are taken to preserve the accesses.

Prevalence of hepatitis C antibodies among hemodialysis patients in Al-hasa region of saudi arabia.

The prevalence of anti-HCV antibodies among hemodialysis (HD) patients was studied at King Fahad Hospital, Hofuf, Saudi Arabia. The records of 189 patients undergoing HD were reviewed. The overall prevalence of anti-HCV antibodies was 43.

The Prevalence of Nasal Carriage of Staphylococcus aureus and Associated Vascular Access-Related Septicemia Among Patients on Hemodialysis in Al-Hasa Region of Saudi Arabia.

A high Staphylococcus aureus nasal carriage rate is frequently seen among patients on hemodialysis (HD) and consequently, these patients appear to be at a higher risk for endogenous S. aureus associated vascular access-related septicemia (VARS). The prevalence of nasal carriage of S.

The role the type of vascular access plays in the transmission of hepatitis C virus in a high prevalence hemodialysis unit.

Background: The necessity of having a vascular access site as well as extracorporeal blood circulation, may add to the risk for patients being dialyzed in units with high HCV prevalence of acquiring hepatitis C virus (HCV) infection. This study endeavors to determine the role the type of vascular access plays in the transmission of HCV infection in the hemodialysis (HD) unit of a Middle Eastern country.

Methods: The records of 198 patients with end-stage renal disease (ESRD) enrolled on maintenance HD from November 1995 to November 2000 at this tertiary care center, were retrospectively reviewed to match the HCV prevalence and seroconversion rates among patients groups being dialyzed through various types of vascular accesses.

The role of the Staphylococcus aureus nasal carriage and type of vascular access in the outcome of high-risk patients on hemodialysis.

Background: Populations of elderly and type-II diabetics are increasing worldwide. Therefore elderly diabetics on hemodialysis (HD), known to have higher nasal carriage rates, are also increasing. These patients are more often dialyzed through central venous catheters (CVCs).

Tunneled catheters' outcome optimization among diabetics on dialysis through antibiotic-lock placement.

Efficacy and safety of antibiotic 'locks', in prevention of thrombotic and infectious complication-related morbidity and mortality, among diabetics dialyzed through tunneled-cuffed catheters (TCCs) has not been effectively investigated. This trial was designed to investigate the outcome of TCCs (n = 109), inserted among 96 diabetic end-stage renal disease patients (March 2002-February 2003), by comparing the catheter thrombosis, catheter-related bloodstream infections (CRBSI), catheter survival, and mortality rates, between the cohorts of 49 patients who had TCCs (n = 51) 'locked' with cefotaxime/heparin (group I) and 47 patients with TCCs (n = 58) filled with standard heparin (group II). Thrombosis was defined as the inability to use catheter at a blood flow of 200 ml/min despite intraluminal thrombolysis.

Enhancing the survival of tunneled haemodialysis catheters using an antibiotic lock in the elderly: a randomised, double-blind clinical trial.

Background: Tunneled-cuffed catheters (TCC) are often used among the elderly to commence and carry out haemodialysis (HD). Complications like infection and thrombosis frequently reduce the lifespan of TCC. The role of an antibiotic heparin 'lock' in the prevention of thrombotic and infectious complications and enhancement of TCC survival in the elderly has not been investigated previously.

The impact of catheter-restricted filling with cefotaxime and heparin on the lifespan of temporary hemodialysis catheters: a case controlled study.

Background: Reduction in the rates of major complications such as infection and thrombosis that limit the lifespan of hemodialysis (HD) catheters could conceivably lead to improved survival of "temporary" non-tunneled HD catheters (NTCs). This study was designed to evaluate the impact of the "locking"' of a broad-spectrum antibiotic-cefotaxime with heparin, on the incidence of catheter thrombosis, catheter-related bloodstream infections (CRBSI) and the NTC lifespan.

Methods: This prospective study included 208 (109 males and 99 females) end-stage renal disease (ESRD) patients of diverse etiology enrolled for long-term HD from July 2002 to June 2003 at our tertiary care hospital.

Prevalence of methicillin-resistant and methicillin-sensitive Staphylococcus aureus nasal colonization among patients at the time of admission to the hospital.

Background: Methicillin-resistant Staphylococcus aureus (MRSA) is an important agent of hospital-acquired infection. The mode of entry of MRSA in the hospital might be on admission of patients with MRSA infection or nasal colonization. The present study was undertaken to determine the prevalence of MRSA nasal colonization among patients on admission to hospital.

Contamination of patients' files in intensive care units: an indication of strict handwashing after entering case notes.

Background: The extent to which bedside patients' files become contaminated and the range of bacterial flora attributable to contamination in high-risk areas of the hospital are not known with certainty. The aim of the present study was to determine the degree of contamination of the patient's files and also to analyze and compare the spectrum of contaminant bacterial flora between the intensive care unit (ICU) and surgical wards, the 2 most high-risk areas for nosocomial transmission of infection.

Methods: Microbiologic samples were collected from the exposed outer surface of the patients' files kept bedside in the ICU and surgical wards with sterile swabs moistened with sterile normal saline.
