Catheters Dysfunction Rate After Instillation of Ethanol 60% Lock Solution in Tunneled Silicone Catheter of Chronic Hemodialysis Patients

Catheters Dysfunction Rate After Instillation of Ethanol 60% Lock Solution in Tunneled Silicone Catheter of Chronic Hemodialysis Patients

The primary objective of the study is to examine the risk of catheter dysfunction during the dialysis session that follows the instillation of ethanol 60% as lock solution in tunneled silicone catheters of end stage renal failure patients treated by hemodialysis.

The catheters dysfunction rate is the primary outcome. The dysfunction is defined as partial or complete occlusion or infection associated with dialysis catheter.

As a secondary outcome, the dialysis quality is also examined (urea reduction rate, total ultrafiltration)

Inclusion Criteria:

Exclusion Criteria:

• Antibiotic therapy during selection phase,
• Partial or complete catheter occlusion during selection phase,
• Venous pressure at dialysis connection > 300 mmHg,

• Patient involved in any other clinical trial or in the exclusion period
• Severe co-morbidity
• Acute or chronic infectious disease
• Evolutive neoplasia,
• HIV, HCV positive serology at inclusion,
