“…Mean blood flow over the life of the catheters was calculated as the mean of all eligible dialysis treatments. Blood flow was modeled using mixed models to account for repeated measures, calculate trends over time, and adjusted for any differences among the groups (5,6). Blood flow between catheters was compared using unpaired t-tests and by including catheter type as an independent variable in the mixed model.…”

“…Previous studies of temporary catheters report mean blood flows in the range of 250-300 mi/mm with recirculation less than 5% in neck catheters but increasing up to 22% in short femoral catheters (4,5). Walters and colleagues in a non-randomized study report average blood flows of 254-264 ml/min (6). Hirsh and colleagues did not report blood flows but were able to achieve a urea reduction ratio of 64.2% using temporary catheters for long term access in ambulatory patients (7).…”

Temporary catheters are still essential for acute dialysis access but their performance has not been compared in randomized trials. We conducted a randomized trial of our standard catheter and a newly designed catheter. The primary outcome was maximized blood flow over the entire use of the catheter. Seventy-six patients provided maximum blood flows. The new catheter provided an average blood flow of 349 ml/min and the standard catheter provided flows of 320 ml/mm (p=0.09). Lumen reversal occurred in 56.8% of dialysis sessions with the standard catheter compared to 27.4% with the new catheter (p<0.001). Left-sided internal jugular catheters and catheters inserted in females provided 103 ml/min and 36 ml/min less blood flow, respectively, compared to right sided catheters and catheters placed in males. Approximately 20% of catheters were removed for poor blood flow. Left sided catheters and catheters in females were more likely to need removal for malfunction but catheter design did not influence removal rates.

“…Previous prospective studies of acute dialysis catheters report mean blood flow rates of 254–298 cc/min with recirculation ranging 3–10% (15,16). Recirculation increases to 18% in short femoral catheters (15 cm) at blood flow rates of 250‐ml/min (17).…”

Acute dialysis catheters are non-cuffed, non-tunnelled catheters used for immediate vascular access. They are primarily used for acute renal failure in bed-bound patients and for short-term use in patients with malfunction of permanent access. Long-term use of acute catheters is not recommended, but does occur with acceptable infection rates in dialysis centers where tunnelled, cuffed catheters are not available. Most acute catheters are made of polyurethane, but silicone catheters are now available with larger lumen sizes capable of delivering blood flow rates over 300 ml/min. Acute catheters should be inserted in the internal jugular or femoral vein under ultrasound guidance to minimize complications. Subclavian catheters cause stenosis, thrombosis, and perforation of vessels. Intermittent catheter malfunction still occurs, particularly for left-sided internal jugular catheters and catheters placed in women. Blood flow may improve with lumen reversal, intraluminal t-PA, or guidewire exchange. Limiting duration of use and dressing catheter exit sites with dry gauze and antiseptic ointments can prevent catheter-related infections.

“…Likewise, Walters et a]. (17), in a study of nontunneled, temporary catheters, required UK lock treatment in up to 9% of hernodialysis sessions. In some reports of the use of thrombolytic therapy to treat catheter clot, neither the drug used nor the method of administration is specified Catheter Lock Technique.…”
